Patent No. 6643606 Patent No. 5702753 JP 2013-168021 A

One object of the present invention is to improve the prior art, for example, to provide an electronic device or the like capable of displaying an appropriate message based on information acquired by the device.

The object of the present invention is not limited to this, and we have the intention to acquire rights by divisional application, amendment, etc. for the structure aiming to obtain the effect of the structure disclosed in the specification and drawings. For example, the present specification discloses a problem in which the descriptions such as "can do", "possible", etc. are replaced with "is a problem". The problems are described as independent ones, and we intend to acquire the rights for the structure for solving each problem independently by filing a divisional application, an amendment, etc. Even if the problem is implicitly grasped from the description of the specification, the applicant intends to claim part of the configuration described in this specification in an amended or divisional application. It also discloses a configuration that solves a problem that combines these independent problems, and has the intention to acquire the right.

(1) In the electronic device, a control unit that acquires message information including a message including traffic-related information from a messaging service and performs control to output the message included in the message information to the user of the vehicle. Be prepared.

In this way, the user can receive messages on the electronic device containing traffic information from the messaging service. As a method of outputting a message to the user, for example, if the in-vehicle device is equipped with a display device or a voice output device, traffic information based on the message may be displayed on the display device, or the message may be displayed on the voice output device. may output traffic information based on the message.

Here, the information about traffic may be information about traffic events that the user should consider while traveling in a vehicle, particularly information about traffic congestion, information about safe driving, or the like. For example, the information may include keywords related to traffic congestion such as "traffic jam", "accident", and "under construction", and keywords related to safe driving such as "policing", "reverse driving", and "wind driving".

In particular, the messaging service may be a social networking service (SNS), and the control unit may have a function of acquiring traffic-related information from messages of the social networking service. In this way, the user can receive traffic-related information among many messages handled by the social networking service. Information related to traffic may be information related to the use of vehicles. In this way, the user can receive information related to the use of the vehicle. As for the use of a vehicle, it is particularly preferable to drive the vehicle.

(2) The control unit preferably has a function of acquiring message information including a keyword related to traffic from the messaging service as the information related to traffic and performing control for outputting the message information.

In this way, the user can receive messages from the messaging service that include traffic-related keywords. Although the messaging service includes messages posted by users other than the user, it is preferable to have a function of obtaining messages including keywords related to traffic from messages posted by other users. Also, it is preferable to have a function not to acquire messages that do not contain traffic-related keywords from the messaging service. In this way, the output messages can be narrowed down to messages containing traffic-related keywords, and the user can avoid receiving messages that do not contain traffic-related keywords from the messaging service.

As a messaging service, for example, Twitter (registered trademark) may be used. In Twitter, a message posted by each user is also called a tweet, and is created and distributed by a user using the service. It may be provided with the ability to periodically retrieve messages from the messaging service via an API. Also, it is good to get messages in real time. In this way, the user can obtain messages containing keywords related to transportation from the messaging service in real time.

(3) The control unit preferably has a function of extracting and outputting a message containing the keyword as a word in the message or as a tag in the message.

In this way, when retrieving a message from a messaging service, a user can receive a message extracted based on keywords or tags included in the message.

For example, a keyword or tag related to the message may be obtained separately from the message. Or you might include the tag in the message, so get that message. At this time, by using this tag, a keyword or tag related to the message may be acquired separately from the predetermined topic message, but the predetermined topic may be a topic related to traffic. The messaging service may be, for example, Twitter (registered trademark) as a social networking service. The tag should be a hashtag, and it is better to use what is included as part of the content of the tweet.

A configuration may be adopted in which messages posted by other users are periodically obtained from the messaging service. In this way, the user can use the system as if he were receiving traffic information. If you want to fetch messages on a regular basis, you may want to fetch messages based on tags. For example, if a tag indicating "#congestion" is used as a traffic-related tag, a message including "congestion" is displayed periodically, so that the user can use the system as if he were receiving traffic information.

(4) The message information may include an attribute related to the message, and the control unit may have a function of outputting the attribute together with the message.

In this way, the user can confirm not only the message but also the attributes of the message. The attribute of the message may be an attribute that serves as an index of the degree of importance of the message. Such an attribute may be, for example, an attribute relating to location or an attribute relating to message rating. By outputting the attributes of the message together with the message, the user can determine the importance of the message according to the content of the output message and the attributes of the message.

(5) The attribute may be at least one of the number of times the message has been reposted, the number of times a reply message has been attached to the message, and the number of times the message has been evaluated.

In this way, the user can specify at least one of the number of times the message has been reposted, the number of times the message has been replied to, and the number of times the message has been evaluated, as attributes corresponding to the message. You can receive it with your message. These attributes may be displayed together with the message, or these attributes may be output by voice together with the message. In this way, the user can grasp the number of times the message has been reposted, the number of times the message has been replied to, and the number of times the message has been rated as ratings for the message.

Here, it is preferable that the messaging service is, for example, Twitter, which is a social network service. In this case, the number of times the message has been reposted may be the number of retweets, the number of times the message has been replied to may be the number of replies, and the number of times the message has been rated may be the number of times it has been "liked." It is preferable that the attribute is obtained by accessing the API provided by the messaging service via the network.

For example, it is preferable to output "X number of retweets have been made" along with the message. In this way, the user can grasp not only the message but also the number of times it has been reposted. For example, the user can infer that the more frequently a message is retweeted, replied, or the like, the more people have instructed the message, and the more reliable the message is.

(6) The message information includes information about the first account that posted the message, and the control unit has a function of outputting information about the first account together with the message. good.

In this way, the user can receive information about the first account that posted the message. The information on the first account may be information handled by the messaging service, for example, information that can identify the account such as the account name and account ID, an image associated with the account, detailed information on the account, and information on the account. At least one of profile information is recommended. In this way, the user can keep track of who posted the message or information about who owns the account.

(7) The control unit preferably has a function of changing the output mode of the message according to information about the first account.

In this way, it is possible for the user to easily grasp the information regarding the account that posted the message according to the output mode of the message. For example, it is preferable to have a function of displaying a message on the display unit as the output destination of the message, and it is preferable to change the display mode such as the color of the message, the size of the font, and the type of the font. In this way, the user can easily determine the information about the account and easily grasp the information. Specifically, for example, in the case of an account related to a user, it is preferable to change the font color and display it. Also, for example, it is preferable to change the size of the message or change the color of the message according to the number of accounts related to the account that posted the message (number of followers/number of followers).

Also, for example, it is preferable to output the voice from the voice output unit as the output destination of the message, and it is preferable to change the output mode such as the volume, tone, and output speed of the voice. This makes it easier for the user to grasp the account information. Specifically, for example, in the case of an account that is not related to the user, the message may be output in a male voice, and in the case of an account related to the user, the message may be output in a female voice.

(8) The control unit preferably has a function of acquiring and outputting any one of profile information, follower count information, and follower count information regarding the first account, based on the account information. .

In this way, the user receives one or a plurality of information regarding the profile, information regarding the number of followers, information regarding the number of followers, etc. as information regarding the account that posted the message, and can grasp information regarding the first account. can.

For example, the profile of the user who posted the message (for example, area of residence, hobbies, favorite things) may be output together. Also, information on the number of followers and information on the number of followers may be output individually, or a plurality of pieces of information may be output together. In this way, the user can obtain information about the account that posted the message.

(9) The information about the account is associated with the second account of the user and the first account that posted the message, or the third account associated with the first account that posted the message. It is preferable that the information is either the number of

In this way, the user can receive information as to whether the account of the user who posted the message is associated with his or her own account. The messaging service may be a social networking service such as Twitter. In this way, the user can know information such as whether the user who posted the message is being followed or whether the user is following the user. As the information on whether or not the account is associated, information that can identify the account of a friend or the account of an acquaintance may be used. In this way, if the user's second account is associated with the first account, the user knows that the post is not from an unrelated account. Therefore, users can follow highly reliable accounts. At that time, if the account that posted the second message follows the account, the user can determine that the message has been posted from a highly reliable account.

Also, it is preferable to obtain the number of accounts associated with the first account that posted the message. The messaging service may be a social networking service such as Twitter. In this way, the user can receive the number of followers of the first account and the number of followers.

Thus, the user can determine that the account is highly reliable when the number of accounts associated with the first account is large. For example, when the messaging service is a social networking service such as Twitter, for example, if the number of followers of the account that posted the message is more than a predetermined number, the user is a message posted from a highly reliable account. can be determined. Further, for example, when the user can determine that the first account is an account of an influencer or the like, the user may determine that the message has been posted by an account with high reliability.

(10) The fact that the user's second account and the first account that posted the message are associated means that the user's second account follows the first account that posted the message. It may be in a state where

In this way, the user can know that the posted message was posted from the account they are following. Here, "following" can be said to relate accounts of other people, and is a function implemented in social networking services, for example. Messages posted by accounts you follow should be displayed on your timeline.

For example, the messaging service may be a social networking service such as Twitter. In this way, it is possible to know information such as whether the user who posted the message is being followed or whether the user is following the user.

(11) The number of third accounts associated with the first account that posted the message may be the number of followers or followers of the first account.

In this way, the user can receive the number of followers or followers of the account that posted the message along with the posted message. For example, a user can determine the credibility of a message or account based on the influence of the account that posted the message (eg, an influencer's account with a large number of followers, etc.). Further, it is preferable to have a function of judging the reliability of an account or a message posted by the account based on the number of followers or followers of the account and outputting the result. For example, if the number of followers is greater than the number of followers by a predetermined percentage or more, the account may be determined to be highly reliable.

(12) The information about the account is whether the second account of the user is associated with the first account that posted the message, and the control unit determines whether the second account of the user is associated with the first account that posted the message. It is preferable to provide a function of outputting information about the first account when the first account that posted the message is not associated with the first account.

In this way, the user can receive information about the account that posted the message if the account that posted the message is not associated with his account. The user's account and the account that posted the message are not associated, for example, when they are not in a friend relationship or in a follower relationship in the social network service. Since the account that posted the message is not associated with it, the user can get information about that account. In this way, the user can confirm what kind of user posted the message. Here, the information about the account may be, for example, the place of residence, birthday, hobbies, etc. of the user who posted the message.

(13) When the second account of the user and the first account that posted the message are not associated, the control unit associates or recommends to associate the first account that posted the message. It is preferable to have a function to

In this way, if the account of the user who posted the message is not associated, the user can receive information that associates or recommends to associate the first account that posted the message. The user can determine whether or not to associate based on this information. For example, when a user sees a message and determines that the user is posting a useful message, the user can easily follow the user. For example, Twitter or the like may be used as the social network service, and if the user does not follow the second account, the user may be recommended to follow the second account. Also, for example, if the user is not following the second account, it may be automatically followed. In addition, it is preferable to have a function of preferentially obtaining messages posted by accounts followed by the user and changing the output mode.

(14) It is preferable to have a function of outputting a fact when the information about the first account that posted the message matches a specific condition.

In this way, the user can confirm that the account that posted the message is an account that meets specific conditions. Here, as a specific condition, for example, if the user has entered a predetermined keyword, the keyword may be included in the profile information of the account that posted the message. As a specific condition, for example, it is preferable that, as an attribute of an account, an attribute value (specifically, the number of followers/the number of followers, etc.) of a related account is equal to or greater than a predetermined threshold. Also, as a specific condition, for example, the account may be an account certified by the messaging service. By knowing that a specific condition has been met, the user can determine, for example, whether to associate the account (eg, follow). In addition, the user can determine whether or not the reliability of the message is high by knowing that the specific condition is met.

(15) The specific condition may be that the first account that posted the message is an established corporate account or an official account authenticated by a messaging service.

In this way, the user can know whether the account that posted the message is an established corporate account or an official account authenticated by the messaging service. The user can determine that the corporate account method is more trustworthy than the personally owned account. In this way, by outputting that the account that posted the message is a company account or a preset company account, the user can determine that the message is highly reliable. For example, it is preferable to have a function that allows the user to set a corporate account in advance, so that the user who posted the message can know that the user has a corporate account. Here, a corporate account is preferably an account owned by a company for the purpose of promotion or public relations activities, and is officially operated by the company, or one or more employees operate under the name of the company. should be an account. In addition, the corporate account may be an account of a private company, but as an account of an organization, an account of an organization such as a national or local government office, an institution, a foundation corporation, a medical corporation, a school corporation, an NPO corporation, etc. should be an account.

For example, it is preferable to have a DB (Data Base), inside or outside the device, in which the user can register a specific account (for example, NEXCO) as a trustworthy account. Also, for example, by analyzing the profile of the account information, it is preferable to specify that it is a corporate account.

Also, if the messaging service is, for example, an authenticated official account (for example, an account with an official badge displayed on the account), a different output mode may be used. In this way, if the account of the poster is an official account and the user determines that the account is highly reliable, knowing the official account can be used to determine the reliability of the message.

(16) The control unit preferably has a function of changing an output mode and outputting the message when the message is addressed to the second account of the user.

In this way, the user can receive the message addressed to him/herself in an output manner different from that of other messages, thereby making it easier to check the message addressed to himself/herself. As for the message addressed to the user, it may be provided with a function of extracting from among the messages obtained from the messaging service, but may also be provided with a function of separately obtaining only the message addressed to the user.

Here, the message addressed to the user's account means, for example, that the message includes information about the second account, that the message includes a mention addressed to the second account, or that the message includes a mention of the second account. It is good to say that there was a reply to a message posted from the account of

(17) The message may be a message referring to a second account of the user.

In this way, users can receive messages that mention their account in the message. Also, for example, it is preferable to have a function to change the output mode of a message referring to the user's account in the message. In this way, the user can receive messages in which he is mentioned. Here, the message referring to the user's account is, for example, information indicating the user's own account in the message (for example, it may be the same as the above-described information indicating the account, such as an identification ID). It should be a message that Also, the messaging service may be, for example, Twitter, which is a social network service, and the message referring to the user's account may be a message mentioning the user.

(18) The control unit preferably has a function of outputting a message to that effect when the posted message indicates that the poster of the message is driving.

In this way, when the user receives the message, he or she can confirm that the message was posted while driving. For example, the message may be a message about traffic jams. When judging that the message sent by the actual driver is highly reliable, the user can confirm the highly reliable message among the displayed messages regarding traffic congestion.

(19) The control unit preferably has a function of not outputting the message when the message is a repost message.

In this way, the user can avoid receiving reposted messages, thereby reducing the number of messages with duplicate content. For example, it is preferable to provide a function of acquiring messages other than reposted messages. By doing so, it is possible to prevent a situation in which the user cannot confirm messages other than reposted messages. For example, if a given posted message is reposted multiple times, the reposted message is not output, so the user can be prevented from receiving messages with duplicate content. Also, when a message is reposted by various users, the same message is repeatedly re-output. The user can avoid having to check the same reposted message repeatedly.

The messaging service may be, for example, Twitter, which is a social network service, and the repost message may be a retweet message. Also, a message containing a specific character string such as "RT" may be used as a retweet message. Also, for example, the repost message may include a quoted retweet. For example, it is preferable to determine that a quoted retweet is a message that includes another message other than the message following "RT" or that includes "QT". Also, for example, it is preferable that the message part following "RT" is not output as a message for the part not output as the message.

(20) Further comprising a location information acquiring unit for acquiring location information of the device itself, the message information includes location information of the message, and the control unit is included in the peripheral range of the location information of the device itself. It is preferable to provide a function of acquiring the message information received from the terminal and adjusting the size of the peripheral range so that the number of acquired message information is included in a predetermined range.

In this way, the user can receive the messages of the peripheral range of the location information of the user's own device so as to be included in the number of cases within the predetermined range. In addition, a predetermined range is searched from the location information of the device so that the number of messages to be output is included in the predetermined range, and messages posted by accounts included within the predetermined range are acquired. It is good to have a function.

At this time, if the number of messages acquired by the device itself is large, the size of the peripheral range should be reduced. Also, when the number of messages acquired by the in-vehicle device is small, the size of the peripheral range may be reduced.

In this way, it is preferable to change the range from which messages are acquired so that the number of displayed messages is within a predetermined range. For example, the range from which the message is acquired may be represented by the distance of the peripheral range centered on the target person's position. Also, for example, the range of message acquisition may be contents such as the age group and sex of the account, the type of car of the installed device, and the attributes of the message.

For example, in the case of information about traffic jams, it is preferable to output a message near where the vehicle is located or to output it preferentially. Preferential output may be output in a manner in which the preferentially output message is easily perceived by the user. Alternatively, the message to be output preferentially should be output earlier than other messages in terms of time, or the message to be output preferentially should be displayed in a more conspicuous position than other messages. . Also, it is preferable to adjust the size of the peripheral range so that the number of acquired message information items is included in the predetermined range. For example, if the number of message information items is 30, a range based on position information may be specified so as to be included in the 30 items. For example, if the number of acquired messages exceeds the range of 20 to 30, control should be performed to reduce the size of the peripheral range. Also, if the number of acquired messages is less than 20 to 30, control should be performed to increase the size of the peripheral range.

Further, the size of the peripheral range may be changed simply by the distance from the center, or may be changed according to the traveling direction of the vehicle, for example. In the latter case, for example, the peripheral range in the traveling direction of the vehicle may be widened. For example, when the vehicle is traveling north on an expressway, the area on the north side in the direction of travel may be expanded. In this way, it is possible to obtain messages related to the direction in which the user is going.

(21) Further comprising a location information acquiring unit for acquiring location information of the device itself, the message information includes location information of the message, and the control unit obtains the location information of the device itself and the location information of the message. It is preferable to have a function of comparing the position information and changing the output mode of the message.

In this way, the user can confirm the relationship between the position where the message was posted and the position with respect to the user, by changing the output mode of the displayed message. For example, a message posted from a position close to the position of the device may be displayed by changing the color, changing the character size, or adding a symbol. In this way, the user can confirm that the content of the message is what is occurring nearby. In addition, it is preferable to change the priority of outputting messages in conjunction with changing the output mode, or instead of changing the output mode. For example, messages within a predetermined distance from the position of the electronic device may be preferentially output.

(22) The control unit preferably has a function of changing an output mode of messages included within a predetermined distance range from the position information of the own device.

In this way, the user can confirm that the message is within a predetermined range from the user's own device by the change in the output mode of the message. Changing the output mode may be, for example, changing the color, changing the size, or changing the font when displaying the message. When the message is output by voice, it is preferable to change the output volume, voice tone, output speed, or the like. The predetermined range may be a range of a predetermined distance close to the position of the device itself. In this case, when the user is driving, since the output mode of the messages included in the range of the predetermined distance from the own device changes, it is possible to preferentially check the messages closer to the own device. .

Also, the predetermined range may be a far distance range instead of or in addition to the short predetermined distance range from the own device. For messages in the long distance range, it is preferable to change the output mode of messages at a predetermined distance or more from the user's position. Here, the near distance range may be, for example, a range equal to or less than the first threshold distance, and the far distance range may be a range exceeding the first threshold distance. Also, the far distance range may be a range exceeding a second threshold distance that is larger than the first threshold. Also, changing the output mode may include not outputting. For example, the message may not be displayed, or the message may not be output by voice.

(23) The control unit preferably has a function of specifying an address or a road name from the message and outputting an output message containing the address or the road name instead of the acquired message.

In this way, the user can receive a message containing an address or road name instead of the acquired message. For example, each user of a messaging service posts messages with different content. The user can check the message posted to the messaging service in an easy-to-understand output rather than as it is. Here, the address may be a combination of the name of the municipality and the name of the town, but it is better to use the name of the prefecture and the name of the municipality. Also, the address may represent any region, such as an intersection name, facility name, or landmark name. Also, the address may be latitude/longitude information or information indicating an area or location, such as a map code. Also, the road names may be names such as National Highway X and Prefectural Road X, road names such as Meiji Dori and Yasukuni Dori, and expressway names such as Chuo Expressway, Tomei Expressway, and Metropolitan Expressway.

(24) The control unit may further include a keyword included as traffic-related information in the output message.

In this way, the user can receive messages containing traffic-related information. Here, for example, traffic information such as "congestion", "traffic congestion", "accident congestion", and "construction congestion", information related to congestion such as "construction", "accident", and "closure", It is preferable to include information on safe driving such as "dangerous driving", "policing", and "police car". Also, the traffic-related information may be content that affects traffic, and may include disaster-related information such as "heavy rain," "flooding," "fire," and "earthquake."

(25) The control unit may further include a function of including in the output message a time that has elapsed since the acquired message was posted.

In this way, the user can check how much time has passed since the message was posted. Therefore, the user can confirm when the message was posted and how long ago the message is, along with the message. For example, if the message indicates a traffic event, such as a traffic jam, the elapsed time may be displayed along with the event. In this way, the user can know that an event related to traffic has occurred, and also confirm when the event occurred and how much time has passed since the event was posted. can do.

Here, the time that has elapsed since the message was posted may be obtained from the difference between the date and time when the message was posted and the current time, if the date and time when the message was posted can be acquired. Also, for example, the elapsed time may be obtained from keywords indicating time in the message (for example, "yesterday", "last night", "today", and "a while ago"). In addition, the control unit analyzes the message, and, for example, outputs that it is past information for a past sentence (for example, when it is determined as a sentence in the past tense). The elapsed time may be, for example, a specific elapsed time such as X minutes ago or X hours ago. good. Also, it is preferable to change the output mode of the message according to the time that has passed since it was posted. For example, when displaying a message, it is preferable to change the output mode based on the elapsed time since the message included in the output message was posted. It is preferable to change the mode of display such as reducing the size.

(26) The control unit preferably has a function of collecting and outputting related messages.

In this way, the user can confirm related messages in an aggregated state. A related message may be, for example, a messaging service in which one message is related to another message. For example, Twitter, which is a social networking service, may be used as the messaging service. By aggregating related messages, users don't have to check similar messages over and over again. For example, in the case of a reposted message, a similar message is output for the reposted message. Therefore, for example, by outputting the reposted message only once, the user can confirm only one of the related messages.

In addition, the collective output here means that a plurality of messages may be collectively output. The collective output may be, for example, displaying only one representative message. As one representative message, the first posted message may be selected, but a new message may be generated and output.

(27) The control unit preferably has a function of collecting and outputting one or more messages that have been replied to one message.

In this way, the user can confirm messages that have been replied to one message in an aggregated state. For example, for a message that is a reply (for example, reply) to a certain message, only the reply source message may be output, but it is preferable not to display the reply (for example, reply) message. As a method of using the messaging service, for example, the reply message often contains more important information than the reply message. Therefore, it is preferable to output the message of the reply source. Also, even if messages are returned to a single message in the form of a thread, it is preferable to aggregate them as related messages.

(28) The control unit preferably has a function of collecting and outputting messages obtained by reposting one message.

In this way, the user can collectively receive the reposted messages. For example, as a repost message (for example, retweet) for one message, only the message of the repost source (for example, retweet source) should be output. In this case, the reposted message (for example, retweet) can be prevented from being displayed. . In general, a reposted (for example, retweeted) message has almost the same content as the reposted (for example, retweeted) message, so it is preferable to display the reposted (for example, retweeted) message.

(29) The control unit preferably has a function of outputting a message including some or all of the messages that are the sources of aggregation.

In this way, the user can receive some or all of the messages that are the sources of aggregation. For example, it is preferable to output (for example, as it is) all of the aggregated messages among the aggregated messages. For example, when messages are aggregated, the user can confirm what kind of messages have been aggregated by outputting the original message as it is or by outputting a part of the message.

(30) The control unit preferably has a function of outputting together the number of messages obtained by consolidating the messages.

In this way, the user can also confirm the number of messages in which the messages are aggregated. For example, the number of times the message has been reposted (eg, retweeted) or the number of replies (eg, the number of replies) may be output together with the message. By confirming the message and the number of aggregated messages, the user can recognize that the message has a greater response. For example, the user can recognize that a message that receives a large response is important or highly reliable.

(31) The control unit preferably has a function of acquiring reposting number information indicating the number of times the message has been reposted, and changing an output mode of the message according to the reposting number information.

In this way, the user can recognize how many times the message has been reposted according to the output mode of the message. For example, when the number of times the message is reposted (the number of replies) is large, the control unit may change the font type or size of the message, or change the color of the characters. Also, it is preferable to gradually change the output mode of the message according to the number of times the message is reposted (the number of replies). In this way, the user can check how often the message has been reposted. For example, as the number of reposts increases, the color of the text may change from white to red. In this case, the user may perceive that the closer the color of the text is to red, the greater the number of reposts (the greater the number of replies). can recognize.

(32) The control unit preferably has a function of displaying the message in a larger size according to the number of reposts.

In this way, the user can recognize how many times the message has been reposted based on the size of the message. For example, the number of reposts may be displayed together with the message, and whether the number of reposts is large or small may be displayed according to the size of the message or the size of the display area. In addition, the user can recognize a message that has been reposted a large number of times as an important message because it is a message that has spread to many people. Therefore, the more important a message is reposted, the larger the message is displayed, so that the user can intuitively grasp the importance of the message.

(33) A light-emitting unit may be further provided, and the control unit may have a function of changing a light-emitting method of the light-emitting unit according to the repost count information.

Thereby, the user can recognize how many times the message has been reposted by the light emission pattern of the light emitting unit. This means that when the device is provided with a light emitting unit, the light emitting method of the light emitting unit changes according to the number of times of reposting. For example, as a light emission method, it is preferable to change the number of flashes, change the luminance, or change the color. For example, in the case of a message that has been reposted many times, it is preferable to increase the frequency of light emission. By doing so, the user can be alerted. In addition, the user can recognize the approximate number of reposts of the message from the light emission pattern of the light emitting unit. For example, when displaying a message with a large number of reposts among displayed messages, it is preferable to output a light emission pattern indicating that the number of reposts is large. In this way, the user can recognize whether or not the message has been reposted many times without bothering to read the message.

(34) The control unit preferably has a function of outputting an aggregated message when the output message is selected.

In this way, the user can receive the aggregated message by selecting the message. For example, if an aggregated message is displayed, the user may select the aggregated message. In this way, the messages that have been aggregated up to now are expanded and displayed so that the user can check each message. As a method of outputting the aggregated messages, for example, the aggregated messages may be sequentially displayed one by one, but it is preferable to display them one by one in a thread.

(35) The control unit may have a function of outputting a two-dimensional code for displaying the aggregated message.

In this way, the user can confirm the aggregated message using the two-dimensional code. For example, the user causes another terminal device (smartphone, tablet, etc.) to read the two-dimensional code. The terminal device displays the aggregated message based on the information (for example, URL, etc.) indicated by the two-dimensional code. Here, the two-dimensional code preferably contains, for example, a URL for displaying a list of aggregated messages. In addition, the aggregated messages may be displayed one by one, for example, but it is preferable to display them in a thread. Note that an encoded image obtained by encoding information other than the two-dimensional code may be used.

(36) The control unit may have a function of changing a message output method according to the number of acquired messages.

In this way, the user can recognize the number of acquired messages depending on the message output method. For example, when the acquired message is displayed by scrolling, it is preferable to switch the speed of scrolling display. Further, for example, when displaying the obtained messages in a predetermined area, it is preferable to change the font size or the size of the display area according to the number of messages. Also, when outputting the acquired messages by voice, it is preferable to change the voice output speed according to the number of acquired messages. In this way, since the message output method changes according to the number of messages, the user can also recognize whether the number of acquired messages is large or small when viewing or listening to the acquired messages. .

(37) The output method may be the output speed or number of messages.

In this way, the user can recognize the speed at which messages are output and the number of messages acquired according to the number of messages being output. For example, when scrolling the messages, the scrolling speed should be increased if there are many messages, and the scrolling speed should be decreased if there are few messages. In this way, for example, the user Depending on the message display speed, it is easy to visually recognize whether the number of acquired messages is large or small. Also, when outputting messages, all the acquired messages may be output, but it is preferable to output within a range corresponding to the number of displayed messages. For example, when a predetermined number (100) or more of messages have been obtained, the predetermined number of messages may be output. At this time, the control unit may also output that not all the acquired messages have been displayed.

Also, for example, when the number of messages is large, it is preferable to increase the scroll display speed of the messages. In this way, the user can confirm many messages. In addition, for example, by viewing messages that are scrolled at a high speed, the user can not only understand that the number of posts is large, but also obtain a sense of realism (for example, an image of a large amount of information flowing). be able to. Also, if the number of acquired messages is small, the scroll display speed should be slowed down. When the scrolling display speed is slow, the user can not only understand that the number of acquired messages is small, but also can easily check the messages and feel calm.

(38) The control unit preferably has a function of changing the output method according to the number of messages obtained per unit time.

In this way, the user can recognize the number of messages depending on the message output method. For example, if the number of messages acquired per unit time is large, the output method should be to output messages quickly, and if the number of messages acquired per unit time is small, the output method should be to output messages slowly. In this way, the user can understand that many messages can be obtained per unit time if the messages are output quickly. Also, the user will know that if the messages are output late, fewer messages will be retrieved per unit time. Also, as a method of outputting the message, when changing the speed, for example, the scrolling speed may be changed, but it is preferable to change the display speed of the telop.

(39) The control unit preferably has a function of judging the reliability of the acquired message and preferentially displaying a message with high reliability or changing an output method.

In this way, the user can preferentially confirm messages with high reliability. For example, messages posted to messaging services contain a mixture of correct and incorrect information. Also, for example, messages posted to messaging services are mixed with messages containing only facts, comments of users who posted, and irrelevant messages. In this way, the messages posted on the messaging service include unreliable messages such as messages not related to traffic, messages contrary to the facts, and messages that are true but have passed since the event occurred. It may contain so-called noise messages such as content messages. By determining the reliability of messages, it is possible to suppress the output of messages that are noise or to give higher priority to messages that are not noise. In this way, the user can preferentially confirm messages other than noise that the user needs.

(40) If the account of the person who posted the message is an account with a predetermined number of followers or more, a set company account, or an official account authenticated by a messaging service, the control unit can provide a highly reliable message. It is preferable to have a function to determine that there is

In this way, the user can confirm the message posted from the accounts with a predetermined number of followers or more, the set company accounts, and the official accounts as highly reliable accounts. For example, the accounts mentioned above are more likely to post with accurate information than private accounts used by individuals. Therefore, these accounts should be determined as highly reliable accounts, and messages posted from these accounts should be determined as highly reliable messages. In this way, the user can preferentially check messages posted from such highly reliable accounts.

(41) The control unit may have a function of determining that the message is highly reliable when the message has been reposted a predetermined number or more or has been evaluated a predetermined number or more. .

In this way, users can receive highly reliable messages determined based on the number of reposts of messages and the number of ratings. For example, in a messaging service, a message that has been reposted (e.g., retweeted) more than a certain number of times or rated more than a certain number (e.g. It should be determined that the message has a high In this way, it is preferable to preferentially display messages determined to be highly reliable. In this way, users can preferentially receive highly reliable messages.

(42) It is preferable to further include a voice input unit capable of voice input, and the control unit has a function of saving the output message as a bookmark when a registration operation is performed by voice input from the user.

In this way, the user can save the message output by voice input as a bookmark. For example, when the user wants to check the output message again or use it later, the message may be saved in the bookmark when the user utters a command indicating the content to be saved in the bookmark. In addition, since the user can perform the registration operation by voice, the output message can be saved as a bookmark even in an environment in which the user cannot perform the operation, such as when the user is driving. Bookmarking means saving a message as information such as favorites. The location where messages are saved as bookmarks may be, for example, a device, but may also be on a messaging service. Messages may also be saved as bookmarks on other devices connected to the device. In addition, a message (eg, message information) itself may be stored as a bookmark, or identification information (eg, a message ID, a URL indicating a message, etc.) specifying the message may be stored.

(43) The control unit may further have a function of obtaining the message information by searching from the messaging service using words that can be extracted as trends in the messaging service as search keywords, and controlling the output.

In this way, the user can receive messages containing trending words in the messaging service. For example, the message to be obtained may be obtained by performing an AND search for words that can be extracted as a trend together with traffic-related information, or by performing an OR search. For example, only trending messages may be acquired from traffic information, or messages including trending words may be acquired together with traffic information. Also, when displaying a message including a trending word, it is preferable to change the output mode of the message. Also, the trending words may be included in a part of the message, or may be included as a tag.

(44) A storage unit that stores login information of a second account that is a user account, wherein the control unit logs into the messaging service based on the login information of the second account, and the control unit may obtain message information based on a second account logged in from the messaging service.

In this way, the user can have the information for logging into the messaging service stored on the electronic device itself. For example, since the login information is stored in the electronic device that the user owns, the user can use the messaging service without worrying about leakage of the login information. Also, for example, the user can reduce the trouble of inputting login information when using a messaging service.

(45) the login information of the second account includes a plurality of pieces of login information, and the control unit logs in to the messaging service based on the plurality of pieces of login information to acquire message information; When outputting the message, it is preferable to change the output mode of the message based on the account logged in when the message is acquired.

In this way, the user can store multiple pieces of login information in the electronic device and switch the login information to receive messages from the messaging service. In this way, since a plurality of login information can be stored, a user can, for example, use a private account that is normally used as login information and an account that is used for the purpose of collecting traffic information with an electronic device. can be used to store two Also, the control unit may use a plurality of stored login information together, but preferably has a function of switching between them. For example, the control unit outputs only the message acquired by logging in based on the first login information when the user switches, or outputs only the message acquired by logging in based on the second login information. It is good to Moreover, when using both, the user should log in based on the first login information and the second login information, and output the messages obtained from both.

(46) The control unit has a function of logging in based on the login information of a plurality of different accounts, and outputting only one of the duplicated messages when the messages obtained from each account overlap. good.

In this way, even when messages are obtained based on a plurality of different accounts, the user can receive only one duplicate message among the messages obtained from each account. For example, when a user outputs messages obtained from different accounts together, if each user's account follows the same other user's account, duplicate messages may be received. Therefore, the control unit should display only one message instead of outputting each duplicate message. By doing so, the user can avoid receiving the same message repeatedly. Also, since duplicate messages are not output, the control unit may, for example, output other messages accordingly. Also, the control unit preferably changes the display mode of the message when, for example, overlapping messages are combined into one.

(47) It is preferable that a display section is further provided, and the control section has a function of displaying on the display section as an output destination of the message.

In this way, the user can confirm the received message through the display unit and can visually see the message. Since the message is displayed on the display unit, for example, when the electronic device changes the output mode, it is preferable to change the display mode. For example, when the electronic device displays by changing the output mode or output method, it can change the size of characters, change the font, change the display color and / or background color of characters, change the display speed, etc. Do things.

(48) A terminal device having a display unit can be connected, and the control unit preferably has a function of displaying the message as an output destination on the display unit.

In this way, the user can see the message through the display section of the terminal device. For example, if the display of the electronic device is small and the display of the terminal is larger, the user can see the message displayed on the display of the larger terminal. Also, for example, even if the electronic device does not have a display unit, the user can view the message through the display unit of the terminal device. As the terminal device, for example, a portable terminal device such as a smart phone, or another in-vehicle display device such as a car navigation device may be used.

(49) The control unit preferably has a function of including pictograms displayed in the messaging service in the message and displaying the message as it is.

In this way, the user can also see the displayed pictogram when viewing the message. In addition, at this time, the user can also view the pictogram displayed by the messaging service as it is on the electronic device. Emojis may be used to express emotions and states. In addition, since the same pictogram used by the user is displayed on the messaging service and on the electronic device, the user can receive the message more easily. When displaying pictograms as they are, the control unit may display pictograms having the same appearance, or may display pictograms that mean the same content even if the pictograms have different appearances. For example, for pictograms of "smiley face", it is preferable that the character codes indicating the pictograms are at least the same.

(50) It is preferable that an audio output unit is further provided, and the control unit has a function of outputting audio to the audio output unit as an output destination of the message.

In this way, the user can confirm the message by voice. Since the user can confirm the message by voice, the user can confirm the message without paying attention to the electronic device even while driving. Therefore, the user can safely confirm the message. Changing the output mode and output method described above may be done by changing the volume of the sound output from the sound unit, changing the tone of voice, or changing the speed at which the sound is output. Also, the method of outputting sound may be, for example, a method of outputting a warning sound or music.

(51) The electronic device is connectable to a management device, and the control unit has a function of acquiring message information including a message including traffic-related information from a messaging service via the management device. Be prepared.

(52) The control unit acquires a message from a management device that acquires message information including a message including traffic-related information from a messaging service, and outputs the message included in the message information to the user. Be prepared.

In this way, the message can be output to the user based on the message information acquired by the management device from the messaging service. For example, a management device obtains a message from a messaging service and outputs it to an electronic device. Since the necessary message is acquired from the management device, the message can be acquired and output without processing by the electronic device.

(53) It is preferable that the computer is provided with a program for realizing the functions of the control section of the electronic device described above.

In this way, the user can receive a message containing traffic-related information via the electronic device via the management device. The electronic device may or may not have, for example, the ability to connect directly to the messaging service in order to obtain messages via the management device.

(54) A system including an electronic device and a management device, wherein the management device acquires message information including a message including traffic-related information from a messaging service, and transmits the message information to the electronic device. and a control unit for controlling the electronic device to receive the message information and output the message included in the message information to the user of the vehicle. should be

In this way, the user can receive a message about traffic information from the messaging service via the management device via the in-vehicle device. The configuration can be simplified because the electronic device does not need to have a communication function with the messaging service.

(55) A function of acquiring message information including a message including traffic-related information from a messaging service, and a function of controlling output of the message included in the message information to a vehicle user through an electronic device; A system having: In this way, the user can receive messages on the electronic device containing traffic information from the messaging service.

Also, the functions (1) to (52) described above can be realized by the management device. That is, the functions described from (1) to (52) can be realized by the electronic device and the management device.

(56) The method includes the steps of: acquiring message information including a message including traffic-related information from a messaging service; and outputting the message included in the message information to a user of the vehicle. It is preferable to use a message output method that

EMBODIMENT OF THE INVENTION Hereinafter, the form for implementing this invention is demonstrated with reference to drawings. The embodiment shown below is one embodiment that provides the present invention, and the content of the present invention should not be construed as being limited based on the following description. In the following description, parentheses may be used, but this does not necessarily mean that the terms in parentheses and the terms before the parentheses have the same meaning.

A service that distributes information to terminal devices and electronic devices in real time is known. For example, as information provided by the service, contents such as traffic accidents, traffic jams, dangerous driving (reckoning driving, reverse driving), fires, etc. included in the disaster feed can provide useful information for users. be. In addition, since the information is distributed at any time, it is useful to convey a sense of realism to the user.

In addition, various methods are known, such as distributing contents related to current affairs news, and expressing and distributing earthquake information (epicenter and seismic intensity) on a map.

However, when viewed at the national level, there is a lot of real information, and although it seems useful at first glance, there is a problem that the amount of information is reduced at the municipal level and the driving road level. rice field. For example, even if a fee-based information distribution service is used, it is good when distributing information on a national level, but when it comes to the level of municipalities and roads, the information is limited, and users feel that the cost is relatively high. There was a problem that the necessary information could not be obtained.

In addition, when receiving content related to current affairs news, there is a problem that generally it can only be viewed and cannot be used as data.

Therefore, in this specification, the above-described problems are solved by utilizing messaging services and social networking services (SNS).

In recent years, services that provide user-generated information, such as messaging services and social networking services, are known. However, there are various messages in this service, and there is not necessarily only valid message.

If the information obtained from these services is displayed as it is on an in-vehicle device, there is a high possibility that the driver will be gazing at the display screen while driving, resulting in safety problems. In some cases.

In addition, since the content sent by each user varies, it is not always the case that the appropriate content is output from the in-vehicle device or the like.

After considering these issues, we decided to solve problems when using messaging services and social networking services (SNS).

By using the name recognition of the above services and the ability to attract customers, for example, it will be an opportunity for more people to know products (such as electronic devices) that correspond to the services, and it will become an opportunity for many young people who use SNS. It is also possible to have the effect of having expectations for purchase desire.

For example, traffic congestion, accident information, and dangerous driving information, which are the contents of messages in a messaging service, can be provided more quickly than other information distribution services, and can provide a lively feeling due to the characteristics of the service. By linking such services, it is possible to provide a system that users find "interesting". In addition, since information can be delivered immediately, it is possible to provide a practically effective system.

By using an interface (for example, twitterAPI) available in the messaging service, it is possible to extract a message (tweet) that allows traffic-related keyword searches on the service. As a result, it is possible to deliver real information using a messaging service even if it is not possible to deliver information with a high degree of urgency, such as paid information delivery services or earthquake early warnings, by interruption.

In addition, it is possible to use the message as it is, but for example, by judging the event from the text and distributing it collectively as "Information on traffic congestion" or "Reported tailgating", it is possible to make it easier for the user to understand. We can provide you with an easy system.

Also, a messaging service interface (eg, twitter API) can automatically post a message (tweet). In this case, it is also possible to provide useful information to other people by posting or reposting (RT) messages directly from an electronic device or from an electronic device via a server, not from a smartphone. can.

In addition, when posting a message, by adding the product name of the electronic device and information on the manufacturer to the message, it is possible to expect the effect of creating an opportunity for many people to know the product.

Messages can be obtained, extracted, and posted (automatically posted) by obtaining the key used in the interface of the messaging service in advance from the service provider.

Also, the electronic device may display information based on the acquired message. For example, if the electronic device can already display telop information such as crackdown information, it is also possible to display telop messages (tweets, reply messages, for example, the contents of Instagram comments).

In addition, the electronic device already displays, as a telop display, enforcement information of the jurisdictional police station based on the municipality in which the electronic device is located. Therefore, the messages to be displayed may be related to the same municipality as the own vehicle.

In addition, electronic devices can display points on a map or blink roads if they are data that can identify locations such as addresses, latitude and longitude, road names, IC, JCT, SA and PA names. It is also possible to identify and display

In addition, if a message (tweet) or a comment is quoted as it is, it may be difficult for the user to understand, and there is a possibility that the contributor will complain about the unauthorized display. Therefore, the contents of the text may be automatically analyzed and converted into "Information on traffic congestion" or "Information on danger of driving in the wrong direction" for display.

In addition, it is difficult to determine the temporal end of the information in the message, and it is difficult for the user to understand. Therefore, "X minutes before" and "X minutes past" may be displayed from the occurrence time. Further, the degradability of information may also be represented by making the color of road blinking lighter according to the elapsed time.

Also, when electronic equipment is used in a vehicle, it is better to avoid manual operation as much as possible. Therefore, it is better to enable the electronic device to operate or post by screen operation by voice recognition. Also, it may be possible to recognize the input voice and create sentences, which are messages to be posted.

Embodiments for implementing the above-described contents will be described below with reference to the drawings.

[1. First Embodiment]
[1.1 Explanation of system]
[1.1.1 System overview]
FIG. 1 is a diagram for explaining the entire system 1. As shown in FIG. The system 1 is configured such that an electronic device 10 that can be placed in a vehicle 50 and a service providing device 30 (server device for providing service) that provides messaging services can be connected via a network NW.

As will be described later, the electronic device 10 may be directly connected to the service providing device 30 via the network NW, or may be connected to a management device, another terminal device (for example, an information processing device such as a smartphone or a tablet, or a car navigation device). device, etc.).

[1.1.2 Description of messaging service]
Next, the messaging service in this embodiment will be explained. A messaging service is a service that allows a user to exchange messages with other users. Unless otherwise specified, the messaging service of the present embodiment assumes a social networking system (SNS), particularly a system using Twitter (registered trademark). Among messaging services, SNS is characterized by the fact that messages are often exchanged between a large number of specified or unspecified users, and the destination of the message (that is, the person to whom the message is to be read) is specified. Many messages are also exchanged. And among the messages exchanged, there is a mixture of messages that contain the information that the users themselves need and those that do not, and often the latter messages are much more numerous. Although this embodiment has been made in consideration of such characteristics of messaging services, it is not intended to exclude messaging services other than SNS.

A messaging service (service) can deliver messages posted by users and systems to terminal devices of each user. Each user's terminal device can acquire messages from the messaging service and display them in chronological order to generate and display a so-called timeline. Also, the individually acquired messages may be displayed on a display device or output as audio from an audio output device.

Here, posting a message means transmitting message information from any terminal device or other service to the server device of the messaging service. The message information includes messages and attributes related to the messages. The message in this embodiment is mainly text, but also includes images (including one or both of still images and moving images) and voice. Attributes also include, for example, information about an account that posts a message (for example, a user ID that identifies an account, an account ID, a user name of a user who uses the account, a message posting date and time, etc.). Also, the message information transmitted from the messaging service to the terminal device may include other attributes. For example, attributes include information about messages that replied to messages, information about reposts (e.g., number of reposts, information about users who reposted), information about ratings (e.g., number of ratings, information about the user) and the like may be included. Further, the image may include information about the image, and the image itself may be included in the message, or information indicating a link destination of the image (for example, URL) may be used.

Also, when the messaging service distributes the message, the terminal device receives the message information from the server device of the messaging service. The terminal device may request and acquire message information from the server device. Also, message information may be periodically transmitted from the server device to the terminal device.

Note that the message information in this embodiment will be described for a case where the terminal device posts to the messaging service and a case where the messaging service distributes the message information to the terminal device, but the message information may differ in content.

The functions of the messaging service will be described, for example, using the timeline in FIG. 2 as an example. The timeline in FIG. 2 displays messages acquired from the service providing apparatus 30 in chronological order on any terminal apparatus. For example, the timeline may be displayed on the display device of the electronic device 10 or may be displayed on the display device of the mobile terminal device 40 .

The acquiring terminal acquires the message from the messaging service. For example, in FIG. 2, four messages are retrieved: messages MS100, MS102, MS104, and MS106.

The terminal device acquires message information from the service providing device 30 . The message information may include user name, account ID, posting date and time, location information, user icon, etc. as information about the user who posted the message. For example, in message MS104, the user name is displayed in area R100, the account ID is displayed in area R104, the posting date and time is displayed in area R106, and the message is displayed in area R108.

Here, the account ID corresponding to the user name refers to the character string after "@". The account ID is any combination of characters such as alphanumeric characters and symbols. Also, the account ID may include double-byte characters such as Japanese.

The user's account may also display a mark (eg, area R130) indicating that the service provider has authenticated. If the user of the message is a celebrity or a company, a third party can easily confirm that the user is not a spoof by displaying the mark.

User accounts can also be associated. For example, by associating a second user, a first user can obtain messages of the second user or obtain information of the second user. In this way, for example, "following" refers to associating special characters. In this case, the first user is a "follower" from the second user's point of view.

In addition, in this embodiment, when a reply is made to a reply-source message, a message is created by including the account ID of the reply-source message in the message. The reply function is called, for example, a reply function or a comment function.

(2) Repost (area R112)
Repost the same content as the message. This reposting may be done by posting the original message as it is, or by reposting it in the form of quoting it in your own message. For example, in FIG. 2, message MS 106 is a reposted message. In this case, the original message is displayed as is. Also, in the area R132, an identification display is performed to indicate that the message is reposted. In area R132, an icon indicating reposting and the user name of the user who made the reposting are displayed. The repost function is, for example, a function called a retweet function or a repost function.

(3) Evaluation (Region R114)
Evaluate messages. This evaluation may be, for example, a positive evaluation such as "like" or a function such as "favorite". Also, it may be possible to evaluate both "Good" and "Bad". In the case of this embodiment, when the user selects the icon of the evaluation function displayed in the area R114, the evaluation is added to the message. Also, when the user selects the icon of the evaluation function again, the evaluation of the message may be canceled. The evaluation function is, for example, what is called a favorite function or a Favorite function.

Note that the buttons displayed in association with the reply function, repost function, and evaluation function described above may be displayed as icons or characters. Also, for example, each function may be executed by performing a gesture operation on a message (eg, tapping or swiping the message).

In FIG. 2, buttons (icons) that can perform each function are displayed. In addition, the number of people who actually performed is displayed next to each button.

Also, the posted message can include location information (latitude and longitude information, location information such as landmarks, etc.) and information about content (for example, ID of uploaded content, URL of content).

The message posting unit 105 posts the message generated by the message generating unit 104 to the service. The message posting unit 105 may simply send a message to the service (server device within the service), or may send posted message information to the service. Hereinafter, the term "transmitting a message" includes not only transmitting a message to a service but also transmitting message information as necessary. Posting a message refers to the process of outputting message information so that the message is posted to the messaging service. The output destination of the message information may be, for example, a device that provides a messaging service, or another device (for example, a relay device such as a management device) interposed between a device that provides a messaging service and an electronic device. good.

The message acquisition unit 106 acquires a message from a service (server device within the service). Specifically, the message acquisition unit 106 acquires the specified number of messages from the service by specifying the number of messages to be acquired, for example. For each message, the service acquires the message and information (acquired message information) including information about the message and attributes.

The acquired message information includes one or more messages. Also, each message may contain information and attributes related to the message. The information and attributes related to the message include, for example, an ID (message ID) that identifies the message, the account ID of the user who posted the message, the account name of the user who posted the message, the date and time when the message was posted, and the place of posting. may be included. Also, the message information may include a message ID to be a reply destination (reply destination).

Note that the message acquisition unit 106 can acquire messages according to conditions. For example, the message acquisition unit 106 may acquire messages based on specified keywords. A keyword may be any character contained in a message, a tag, or the like. Attributes related to the message may include, for example, the number of times the acquired message has been replied to, the number of times it has been reposted, the number of times it has been evaluated, and the like.

Here, the message acquisition unit 106 can acquire the acquisition message information (message) from an acquisition destination as needed. For example, the message acquisition unit 106 may acquire necessary messages directly from the service. Also, the message acquisition unit 106 may acquire a necessary message from acquired message information once stored in the message information storage area 196 .

For example, the message acquisition unit 106 specifies the number (number of cases) of acquisition message information to be acquired from the service, and acquires the message information. At this time, keywords required for the service can be specified. For example, by designating the keyword "accident", the message acquisition unit 106 can acquire messages containing "accident" in the message. Also, by designating the tag "#accident", the message acquisition unit 106 can acquire messages including the tag "#accident" from the service.

Further, when the number of messages is simply specified, the message acquisition unit 106 acquires as many messages as the number of messages that can be acquired. Then, message acquisition section 106 stores the acquired message (acquired message information) in message information storage area 196 . It should be noted that the message information storage area 196 may temporarily store the obtained message information, may store only a predetermined period of time, or may store the entire message information.

Then, the message acquisition unit 106 may acquire a message containing a predetermined keyword (for example, “accident”) from the acquired message information stored in the message information storage area 196 .

In this way, the case where the message acquisition unit 106 acquires a message includes the case where the message is acquired directly from the service and the case where the message is acquired from the message stored in the message information storage area 196. can be selected accordingly.

Note that these two acquisition sources may be combined. For example, messages from the previous day or earlier may be obtained from the message information storage area 196, and messages for the current day may be obtained from the service. Also, the message acquisition unit 106 may acquire the message from the message information storage area 196 when the message cannot be acquired from the service due to the communication environment.

The message output unit 107 outputs the acquired message. For example, the message included in the obtained message information and the information/attributes related to the message can be displayed or output by voice.

Also, the message output unit 107 may display each message one by one, or may display a timeline arranged in chronological order.

The timing determination unit 108 determines the timing of posting a message to the service and the timing of acquiring the message from the service. For example, the timing determining unit 108 prompts the message generating unit 104 to generate a message when determining that it is time to post a message based on the state of the vehicle. Further, when a message is generated by the message generation unit 104 or when a message is input by the user, the message posting unit 105 is prompted to post the message.

Also, the timing determination unit 108 determines the timing of posting a message from the service and the timing of acquiring the message. For example, when it is determined that it is time to post a message, the message generating unit 104 is prompted to generate a message. Further, when the timing determining unit 108 determines that it is time to acquire a message from the service, the timing determining unit 108 prompts the message acquiring unit 106 to acquire the message from the service.

Here, the timing determination unit 108 determines that it is time to post a message when a trigger for posting a message is detected. For example, the timing determination unit 108 may detect a trigger at the timing when the state of the vehicle 50 changes, or may detect an operation input from the user as the trigger. Triggers may also be received from other devices (eg, drive recorders, etc.). In addition, the timing determination unit 108 changes the state of the vehicle 50, for example, when there is a traffic jam, when there is an accident, when the vehicle is subjected to tailgate driving, when the control radar is received, and when the car location radio is received. This is the case when there is some change.

More detailed processing and operations of the message generation unit 104, the message posting unit 105, the message acquisition unit 106, the message output unit 107, and the timing determination unit 108 will be described in detail in the following embodiments.

The storage unit 190 secures an account information storage area 192 , a vehicle information storage area 194 , a message information storage area 196 and a setting information storage area 198 .

The account information storage area 192 is information relating to user accounts. For example, it stores IDs (account IDs) and passwords related to user accounts. Also, for example, authentication information and access tokens may be stored together as information related to the user's account.

The vehicle information storage area 194 stores information about the vehicle 50 acquired by the electronic device 10 . The timing to be stored as vehicle information is stored at predetermined time intervals (for example, every 5 minutes, every 10 minutes, every hour, once a day).

The message information storage area 196 stores information about messages. For example, it stores a message (posted message information) generated by the message generating unit 104 and a message (obtained message information) obtained by the message obtaining unit 106 from the service.

[1.2.2 Other devices]
The service providing device 30 is a device that provides a messaging service, and is a device that includes, for example, a control unit, a communication unit, and a storage unit. The service providing device 30 is, for example, a device owned by a business that provides messaging services. For example, Twitter (registered trademark) as an SNS, Facebook, Instagram, Sina Weibo, TikTok, etc. It may be a device owned by a service provider, or a messaging device that can be connected via a network. It may be a device having a function of providing a service. Hereinafter, the term "service" is simply used to include messaging services and social networking services.

The mobile terminal device 40 is a device owned by a user and capable of processing information, and includes, for example, a control unit, a communication unit, a storage unit, a display unit, and the like. The mobile terminal device 40 is specifically a device such as a smart phone or a tablet. It should be noted that any device such as a car navigation system provided in a vehicle may be used as long as it is a terminal device.

The electronic device 10 may communicate with the management device 20 and the service providing device 30 by using the communication function (for example, tethering function) of the mobile terminal device 40 .

[1.3 Flow of processing]
Next, the flow of processing in this embodiment will be described.

The overall flow of system 1 will be described. FIG. 9 is a diagram for explaining the flow of processing in this embodiment.

First, the control unit 100 determines whether or not it is time to post a message (step S102). Here, whether or not it is time to post a message is determined by determining whether it is time to post a message to the service or whether it is time to post a message. These may be determined by the timing determination unit 108 .

When determining to post a message (step S102; Yes), the control unit 100 executes message generation processing (step S104). In the message generation process, for example, the message generation unit 104 generates a message to be posted and posted message information. The generated message (posted message information) may be temporarily stored in the message information storage area 196 .

Subsequently, control unit 100 executes message posting processing (step S106). For example, the message posting unit 105 posts the message (posted message information) created by the message generating unit 104 to the service.

Also, the control unit 100 determines whether it is time to acquire a message from the system (step S110). When it is time to acquire a message (step S110; Yes), the control unit 100 executes message acquisition processing (step S112). For example, the message obtaining unit 106 obtains obtained message information from a service. Then, the control unit 100 executes message output processing (step S114). For example, the message output unit 107 displays one or a plurality of messages included in the acquired message information on the display unit 120, and outputs audio from the audio output unit 130. FIG.

In this way, by executing the processing of the present embodiment, it is possible to post a message from the electronic device 10 to the service. Also, the electronic device 10 can obtain and output a message from the service. That is, information can be easily shared between users through the service.

[1.4 Example]
Examples that can be implemented using this system are described below. It should be noted that the following examples respectively describe aspects of the present embodiment. Although the embodiments are described separately for convenience of explanation, a plurality of embodiments may be combined.

[1.4.1 Example of Posting a Message According to Vehicle State]
This embodiment is an embodiment in which the electronic device 10 determines a trigger for posting a message from the state of the vehicle and posts the message to a service. Users can share vehicle status with other users through postings to the messaging service. As an effect of sharing with other users, for example, sales of in-vehicle devices such as the merit of safe driving support on the user side, appeal to young people with many SNS users, and expectation of improvement of purchase desire It is possible to expect merits on the side of the sales company, such as improved recognition of the company and sales promotion. The state of the vehicle may be the state of the vehicle itself, but may also be the state of the surroundings of the vehicle.

The state of the vehicle may be, for example, a state in which the vehicle is in contact with a predetermined event in traffic, and particularly an event that may hinder the vehicle from proceeding. Such events include traffic jams around the vehicle, accidents, construction work, speed control, bad weather, fires, landslides, and flooding. At least one of the following: Other disasters have occurred, and traffic closures and other traffic restrictions are in place. It is preferable to specify based on the vehicle speed of the vehicle that the vehicle is hindered from advancing due to an event, such as congestion around the vehicle. The vehicle speed may be specified based on the change in the positional information acquired by ), but it is preferable to acquire the vehicle speed information from the vehicle and specify the vehicle speed. If information can be obtained from the vehicle, such as when the system is implemented in an on-board device, the vehicle speed can be obtained via the OBDII ("II" is the Roman numeral for "2") connector. .

Here, the vehicle is preferably a two-wheeled vehicle or a four-wheeled vehicle with a motor, but may be a vehicle such as a passenger car, truck, or bus that travels on roads. The state of the vehicle may be obtained based on information obtained from a sensor or the like provided in the vehicle, but may be determined based on information obtained from a sensor provided in the vehicle.

The sensor may be, for example, an acceleration sensor, a gyro sensor, a GPS module, or the like. It is preferable to determine the state of the vehicle by comparing the information acquired from the sensor and the information stored in advance. As regards the state of the vehicle as being in a certain state, only being in a predetermined state itself may be considered, but it is more preferable to include being in a state similar to the predetermined state. The surrounding conditions of the vehicle include, for example, a state in which the following vehicle is unusually approaching (for example, the following vehicle is driving on the road), a state in which another vehicle encounters dangerous driving, or a vehicle running in the wrong direction. It is preferable to assume that there is a

Generating the message information based on the state of the vehicle may be generating the message information so as to include a message reflecting the state of the vehicle. All of the messages included in the message information may be automatically generated without the user's character input operation, that is, without manual input, but a part of the message may be generated. The former is particularly advantageous in that it reduces the user's operational burden associated with creating a message for the driver, etc., and can be easily posted, while the latter improves the degree of freedom in creating messages to be posted. It is advantageous in that it enables posting of various message information. Reflecting the state of the vehicle may allow the user to directly or indirectly grasp the state of the vehicle. The messaging service may be, for example, Twitter (registered trademark) as a social networking service. In Twitter, messages created and posted by each user are also called tweets.

In the first embodiment described below, as an example of the state of the vehicle, a case will be described in which "traffic jam" is detected as an event that may hinder the progress of the vehicle, and a message is posted.

In this embodiment, the control unit 100 determines that it is time to post a message when the vehicle 50 is in a traffic jam. Here, by posting a message to the service when the vehicle 50 is in a traffic jam, information can be shared with other users almost in real time.

Here, for example, the following processing is conceivable as the processing by which the control unit 100 determines that the vehicle 50 is in a state of traffic congestion.

(1) Speed of vehicle 50 The control unit 100 determines that the vehicle 50 is in a traffic jam when the current speed of the vehicle 50 is equal to or lower than the judgment speed and the time during which the vehicle 50 is running at the judgment speed or lower continues for the judgment time. .

The determination speed and determination time are stored in the setting information storage area 198 as setting information in advance or by the user. For example, if the determination speed is 10 km/h or less and the determination time is 3 minutes, the controller 100 determines that there is a traffic jam if the vehicle continues to travel at 10 km/h or less for 3 minutes or more.

Also, the determination speed and the determination time may be changed according to the type of road. For example, the determination speed may be stored as 10 km/h for general roads and 40 km/h for highways.

(2) Position of vehicle 50 The control unit 100 determines that there is traffic congestion when the current position of the vehicle 50 does not move from the same place or within a predetermined range for a predetermined time. For example, the control unit 100 determines that there is traffic congestion when the vehicle 50 is included in a certain range even after the determination time has elapsed. Also, the control unit 100 may determine that there is a traffic jam when the vehicle 50 stops frequently.

(3) Determination from external information For example, when the electronic device 10 can acquire image data that can capture the situation outside, the control unit 100 may determine that there is a traffic jam by analyzing the image. . For example, it may be determined that the image data being shot is congested when the video data changes slowly or when there is no change for a predetermined period of time. Further, it may be determined that the traffic is congested when the brake lamp of the preceding vehicle is continuously lit.

Subsequently, the message generation unit 104 generates a message indicating that there is a traffic jam. The message generator 104 may generate messages that are useful to other drivers. For example, the message generation unit 104 may generate a message that simply indicates that there is a traffic jam, such as "We are currently in a traffic jam." Also, the message generation unit 104 may generate an easy-to-understand message such as "Ah, it's a traffic jam. It's frustrating." Such a message is to create and post a message (article) that is useful to the person (driver) using the service.

Further, the control unit 100 may include in a message and transmit according to the driver's emotions and actions. For example, the control unit 100 may determine from the vehicle information of the vehicle 50, when it detects that the brakes are being stepped on frequently, to determine the feeling of "wouldn't you like to go faster?" and include it in the message. Further, the control unit 100 determines from the vehicle information of the vehicle 50, when the vehicle 50 frequently changes lanes (for example, when many turn signal signals are detected), the emotion "I want to get out of the traffic jam!" and may be included in the message.

Also, the control unit 100 may include corresponding pictograms according to the driver's emotions and actions. For example, the control unit 100 may include a "smiley" emoticon in the message when things are progressing smoothly. In addition, the control unit 100 may include a “crying face” emoticon in the message when the traffic is congested.

Also, the control unit 100 may change the pictogram according to the length of the traffic jam and the time spent in the traffic jam. For example, the control unit 100 may include many pictographs of cars when the congestion is long. For example, the control unit 100 may increase the number of pictograms by one every time five minutes have passed since the time of being stuck in a traffic jam.

By posting messages over time, other users can check the traffic situation in real time. For example, by periodically displaying traffic jams on the timelines displayed on other users' terminal devices, not only can the traffic jams be realistically communicated, but also the extent of the traffic can be seen. can be confirmed.

In addition, since a plurality of users of the electronic devices 10 post messages in the same way, other users can also confirm that many people are stuck in a traffic jam. As a result, the message is based on the actual state of the vehicle 50 as compared with general traffic jam information, so that it is easier to grasp the occurrence of traffic jam.

Thus, according to this embodiment, the state of the own vehicle can be shared with other users through posting to the service. For example, it can be shared with the state of the vehicle (for example, traffic congestion is occurring due to the speed of the vehicle).

In addition, recognition of sellers of in-vehicle equipment (an example of electronic equipment), such as benefits for users to support safe driving, appeal to young people with many SNS users, and expectations for increased purchase desire Merits on the side of the seller, such as improvement and sales promotion, can be expected.

Also, by posting messages on a regular basis, increasing the number of accounts related to the account (e.g., followers, friends), it is important to have a mechanism to nurture the account so that the message will be displayed on the timeline. Yes, we can provide such a mechanism.

Users can also share messages with other users through postings to the messaging service, indicating that the vehicle has encountered an event that could impede its progress as a vehicle condition. Events that can cause the vehicle to be impeded are as described above. It is preferable to provide a function of posting when it is determined that the vehicle has come into contact with an event that may hinder the vehicle from proceeding. In this way, the messaging service enables third parties to receive information in real time about events that may cause the vehicle to be impeded. In addition, since the information is actually generated based on the state of the vehicle, it can be created and posted more easily than when the user manually creates and posts all of the message information. In addition, since the information is actually generated based on the state of the vehicle, the user can share more correct information with third parties. Traffic congestion is an event that can hinder the progress of a vehicle, and is an event that users have relatively many opportunities to come into contact with, and sharing that information is particularly valuable. You can easily create and post messages about

Users can also share generated messages with other users through postings to the messaging service, based on detailed information about events that may cause the vehicle to be impeded. For example, the detailed information about the event may be, for example, the situation in which the event is occurring, the time actually taken to avoid the event, and the like. In this way, a third party can not only know that an event is occurring that may cause the vehicle to be impeded, but also recognize more detailed information. If the event is a congestion, the message may be generated based on the congestion detail information about the congestion, so that detailed information about the congestion can be shared.

Users can also include pictograms based on event details in their messages and share the messages with other users through posting to the messaging service. Pictograms here are preferably pictograms that can be used in messaging services. Also, it is good to use pictograms included in other people's messages (tweets). Emojis may be used to represent emotions and states. Also, it is preferable that the same pictogram used by the user is displayed in the messaging service and in the display on the vehicle side. In this way, pictograms that look the same are displayed, so that the user and the third party can see messages using the same pictograms on both the messaging service and the display on the vehicle side. Pictograms may have different appearances, but it is better to display pictograms that mean the same content. For example, for pictograms of "smiley face", it is preferable that the character codes indicating the pictograms are at least the same. If the event is traffic congestion, the third party can intuitively grasp the traffic congestion situation through the pictograms.

In addition, the user can post a message to a messaging service with a different number or content of pictograms depending on the size of the occurrence range and/or the time it takes to pass through the occurrence range of an event that can hinder the progress of the vehicle. Can be shared with other users. For example, when the occurrence range of the event is large, it is preferable to repeatedly display many pictograms. For example, if it takes time to pass through the generation range, one pictogram may be used. For example, when changing the contents of pictograms, it is preferable to change the pictograms expressing the user's state of mind according to the occurrence range of the event. For example, if the range of occurrence of the event is small, emoticons that express the state of mind such as "smile" or "expressionless" are used, and if the range of occurrence of the event is large, "anger" or "sadness" is used. It is preferable to use emoticons that express such a feeling. In this way, a third party can easily determine the degree of occurrence of an event that may hinder the progress of the vehicle by looking at the pictogram. If the event is traffic congestion, it is preferable to increase the number of pictograms or change the content each time the traffic congestion distance increases by a predetermined distance such as 2 km, 5 km, 8 km, and so on. In this way, a third party can easily determine whether the traffic jam that has occurred is long or short by looking at the pictograms.

In addition, the user can include in the message information about the image stored in the storage unit that stores the image, and share the message with other users through posting to the messaging service. The information about the image should be in the form of an image file. Also, the information about the image may be link information (for example, URL) indicating the image file. In this way, the third person can not only check the message only by text, but also check the image represented by the image file, so that the third party can obtain information in a more comprehensible manner. The information about the image may be, for example, useful information for grasping the occurrence of an event that may hinder the progress of the vehicle. In this way, the user can easily share the exact content of the situation of occurrence with a third party. The information about the image may be the image itself stored in the storage unit, or may be information generated from the image stored in the storage unit. The information generated from the image may be information describing the content of the image, for example, text information. As the text information, for example, it is preferable to perform image recognition and generate text information describing the occurrence of an event based on the recognition result.

The user can also include in the message information about the captured image of the display screen to assist in driving the vehicle, and share the message with other users through posting to the messaging service. An information processing terminal carried by a user such as a smartphone may be used as a device for displaying a display screen for assisting driving of a vehicle. It should be a screen. Examples of in-vehicle devices include a drive recorder that provides shooting and recording functions, a navigation device that provides navigation functions such as route guidance, and a detector that has a notification function that notifies that a speed control point is in a predetermined proximity relationship. (For example, a radar detector, a laser detector, etc.). A map is often displayed on a display screen for assisting driving of a vehicle. Therefore, for example, a display screen including a map may be captured as a display screen for assisting driving of a vehicle, and a message including an image including the map may be generated. It is preferable to capture the display screen including the location (eg address or road name) and generate a message including the image including the location. In this way, a third party can use the image included in the message to check a map of the area where an event that could impede the progress of the vehicle has occurred, and also the location from the image. Become. Execution of the capture may be instructed by manual input by the user, for example, it may be possible to perform a one-touch operation. Capturing may be performed without explicit user direction, for example, when certain events occur, or periodically. The image used for posting may be instructed by the user, or may be selected without such instruction.

Also, after including information about the image taken outside the vehicle in the message, the message can be shared with other users through posting to the messaging service. The outside of the vehicle preferably includes at least one of the forward, rearward, and lateral directions of the vehicle, and preferably includes the forward direction. A third party can visually confirm to what extent the condition has occurred if the image shows a situation in which an event that may cause the vehicle to be hindered from proceeding is captured. If the event is a traffic jam, it is preferable to photograph the outside of the vehicle, particularly the area in front of the vehicle. In this way, a third party can visually confirm how much the state is occurring from a congested train or the like. Here, the photographing device may be provided in the in-vehicle device, or may have a configuration separate from the in-vehicle device. For example, the in-vehicle device may be equipped with a camera that captures the front of the vehicle. Alternatively, an image from a drive recorder installed in the vehicle may be used. Alternatively, a camera provided in a smartphone or other information processing device owned by the user may be used.

A user can also include a location-based map in a message and share the message with other users through posting to a messaging service. The map based on the positional information may be a map of the vicinity of the position indicated by the positional information, for example, a map of a predetermined distance range centered on the position. In this way, by checking the map, a third party can grasp the specific position at which an event that may hinder the progress of the vehicle has occurred. If the event is a traffic jam, an image of a map around the place where the traffic jam is occurring may be used. This makes it easier for a third party to understand the relationship between the location and the occurrence of traffic congestion.
Next, an embodiment based on the idea as described above will be described.

[1.4.2 Example of Posting Detailed Message of Congestion]
This embodiment is an embodiment in which the details of the traffic congestion are included in the message when the vehicle 50 is in a traffic congestion state.

For example, in the first embodiment, the message generation unit 104 generates a message indicating that there is a traffic jam. In this embodiment, the message further includes detailed information about the traffic jam (detailed traffic jam information).

Here, the traffic congestion detailed information may include the extent of traffic congestion and the cause of traffic congestion. For example, the start time and start position of the traffic jam, the time and position of exiting the traffic jam, the time spent in the traffic jam (the time the vehicle 50 passed through the traffic jam range), the length of the traffic jam (distance ) may be included in the message.

For example, the control unit 100 detects that the vehicle 50 is congested by the method described above. The control unit 100 provides traffic congestion information such as the date and time, the position of the vehicle 50 (latitude and longitude information, landmark information, mobile phone base station information, etc.), the prefecture in which the vehicle 50 is located, the municipality, the name of the town, and the location of the vehicle 50. Acquire one or a plurality of traveling directions (directions of roads), road names, and the like.

Then, the message generator 104 may include in the message one or a plurality of pieces of the acquired traffic jam detailed information. At this time, the user may select information to be included in the message.

Also, the cause of the traffic jam and the location may be included in the message as tags. The message may also include the names of congested roads, municipalities, and landmarks. Also, road names, municipalities, and landmarks may be included as tags.

The operation of the message generating unit 104 when generating detailed traffic congestion information will be described. The control unit 100 acquires the position at which the vehicle 50 is in a congested state as the first position. Then, the position where the vehicle 50 has left the state of congestion is acquired as the second position. The congested position is the start position at which the vehicle 50 is determined to be congested as described above. Further, when the vehicle 50 transitions from the state of the traffic jam described above to a state in which the traffic jam is removed, the control unit 100 determines that the traffic jam has passed.

As a result, the message generator 104 can create a message that was congested from the first location to the second location. At this time, the message generation unit 104 may include in the message the time it took for the vehicle 50 to clear the traffic jam and the distance indicating the extent of the traffic jam. The message generation unit 104 may also include the road (name of the road) on which the traffic is congested, the direction of the road (the direction in which the vehicle travels on the road), the names of landmarks near the congested area, and the like.

For example, the first point at which the vehicle 50 is congested is "near the intersection of Minami-Ikebukuro 1-chome", and the second point at which the vehicle 50 is out of traffic is "above". When it is determined that the traffic is near an intersection in Ikebukuro,” the message generation unit 104 may generate a message saying, “There was a traffic jam from Minami-Ikebukuro 1-chome to Kami-Ikebukuro.”

Further, the control unit 100 may generate a message saying that "traffic jam near the intersection in Kami-Ikebukuro" is generated after the traffic jam clears (passes through the second point).

In addition, the message generating unit 104 may also include the name of the road on which the traffic is congested in the message or as a tag. For example, if the name of the congested road can be acquired as Meiji-dori, the tag "#Meiji-dori" may be added to the message.

In addition, the message generation unit 104 may generate a message including the names of landmarks included in the congested section. For example, in the case of the above section, since Ikebukuro Station is included in the congested section, the message generating unit 104 may generate a message saying "There was traffic congestion near Ikebukuro Station."

In addition, the message generation unit 104 may include in the message an image of a map corresponding to the traffic congestion section. For example, the message generation unit 104 may change the color of the road in the portion corresponding to the area of traffic congestion in the image data of the map. Also, the message generator 104 may display pins at the first point and the second point.

Also, the message generator 104 may include the cause of the traffic jam in the message. For example, if a second point of congestion is undergoing construction, a message may be generated that the congestion is caused by construction. In this case, the image around the second point may be included in the message, or the user may select the cause. In addition, the control unit 100 may acquire the cause of traffic congestion from other information such as VICS (registered trademark).

In this way, by posting a message containing detailed information about traffic congestion to the service, more detailed information can be shared with other users. In particular, since the message is posted to the service, it becomes easier for users who are not associated with the service to search for information on traffic jams. For example, in the case of the Twitter service, real-time traffic information can be shared by users who do not follow users by searching with keywords or tags, or by registering in a list. In addition, as detailed information on traffic congestion, information obtained by actually driving a vehicle, such as the length of traffic congestion and the time involved in traffic congestion, can be easily obtained.

Users can also share messaging services with other users through postings to the messaging service that tell them about location information as well as the occurrence of events that could cause the vehicle to be impeded. The position information may indicate the position at which the vehicle encountered an event that could cause the vehicle to be impeded. This positional information indicates the position or its surroundings where an event that may hinder the progress of the vehicle is occurring. In this way, the user can share the highly accurate message that the location where the event is occurring is the vehicle's current location with a third party. Also, when a third party sees the message, he/she can recognize that an event that may hinder the progress of the vehicle is occurring and the location where the event is occurring. If the event is a traffic jam, a message will be generated that includes content related to traffic congestion and content based on location information.

In addition, users can share with other users through messages and postings to messaging services, including the causes of events that may hinder the progress of the vehicle. By doing so, a third party can recognize the cause of the occurrence. The message may include information indicating the cause of an event that may hinder the progress of the vehicle, such as "accident", "construction", "landslide", "flood", "fire", and "disaster". In this way, a third party can determine whether the cause of the occurrence is a usual reason or an unusual reason, and whether it will take time for the event to be resolved. It is sufficient if an event and its cause are paired. For example, an event that can hinder the progress of a vehicle is "traffic jam" and its cause is an "accident." The possible event may be an "accident" and the cause may be a "collision between vehicles". If the event is a congestion, the message may be generated based on the congestion detail information about the congestion, so that detailed information about the congestion can be shared. A third party can determine whether the cause of the traffic congestion is the usual reason, whether it is an unusual reason, or whether it will take time for the congestion to be resolved. Causes include "accidents," "construction," "landslides," "flooding," "fires," "disasters," and "collisions between vehicles." good too.

Users can also share with other users through postings to the messaging service the extent of events that may cause the vehicle to be impeded. The range of congestion may be, for example, a range from the first point to the second point. The first point may be, for example, at or near the beginning of the range of events. The second point may be at or near the end of the range of events. A third party can confirm whether the event occurs at a place where the event occurs normally, or confirm the distance at which the event occurs. By doing so, for example, a third party can make a decision to bypass the route that is included in the range where the event is occurring. If the event is a traffic jam, the occurrence range of the event may be the range from the head to the tail of the vehicle line, the length of the vehicle line that constitutes the traffic jam, or the like.

In addition, as the range of occurrence of an event that may cause the vehicle to be impeded, the user first determined to have come in contact with the event, and determined to have exited the state of coming into contact with the event. The second point can be shared with other users through posting to the messaging service. A third party can check the message to see where the first and second points are relative to the starting and ending points of the event and how long it spans. can recognize. Further, by doing so, for example, a third party can confirm the range in which the event is occurring, so that it becomes easier for the third party to select a route to avoid coming into contact with the event, for example. If the event is a traffic jam, the vehicle can share the origin point of the traffic jam and where it got out of the traffic jam. You can check the information based on

In addition, the user can post to the messaging service a message that includes information on the distance and time of the occurrence of an event that may hinder the progress of the vehicle, and share the message with other users. A third party who has confirmed the message can easily determine whether to continue driving or to avoid the occurrence range, based on the length of the occurrence range of the event. If the event is a traffic jam, it is good to post the area where the traffic jam occurs and the passage time when the vehicle enters the area. This can be used for route selection, travel time estimation, and the like.

In addition, when an event occurs on the road on which the vehicle is traveling that may impede the progress of the vehicle, the user can post a message containing the name of the road with other users through posting to the messaging service. can be shared. Since the road name is included in the message, a third party can grasp the road on which the event is occurring. In addition, since the road name is included in the message, a third party can know information about the event in a manner similar to traffic information broadcast on news programs such as radio. If the event is a traffic jam, a third party can confirm which road name is causing the traffic jam, and use this information to select a route when traveling by vehicle, estimate travel time, etc. can.

In addition, users can share with other users not only the name of the road on which the vehicle is traveling, but also the direction of the road on which an event that can cause the vehicle to travel is occurring, through posting to the messaging service. can. The direction of a road may be the direction in which a vehicle determined for the road should travel, for example, up/down, eastbound/westbound, southbound/northbound, outer/inner, and the like. In this way, a third party can confirm not only the road name but also the direction of the road in the message. It becomes easier for the user to determine whether or not the traffic jam affects the direction of travel of the user. If the event is a traffic jam, a third party can check more detailed information such as the name of the road where the traffic jam is occurring, the direction of the road where the traffic jam is occurring, along with the driving status of the vehicle. This can be used for route selection and travel time estimation.

The user may also send a message to the messaging service, with the message including a location-based map identified with detailed information about the event that could cause the vehicle to be impeded. can be shared with other users through posts. When a third party confirms the message, for example, the third party can confirm not only the text information but also the map identified and displayed based on the detailed information of the event. The map based on the positional information may be a map of the vicinity of the position indicated by the positional information, for example, a map of a predetermined distance range centered on the position. As the identifiably displayed state, for example, it is preferable to identifiably display the place where the event is occurring or the occurrence range of the event. In this way, a third party can visually determine the occurrence range and distance of the event. If the event is a traffic jam, the third party can express detailed information about the traffic jam on the map. , making it easier for the third party to grasp detailed information about traffic congestion. As a messaging service, for example, Twitter or the like may be used. In Twitter, text information is text information posted by each user, and is also called a tweet. The text information may include tags, and the tags may be hash tags. The map may be posted using a Twitter function that attaches an image file.

Users can also include tags generated based on event details in messages and share the messages with other users through posting to the messaging service. The tag may be, for example, text information indicating an item included in the detailed event information, such as the location where an event that may hinder the progress of the vehicle has occurred, the name of the road, and the like. In this way, a third party can easily retrieve the detailed information by selecting the tag in the messaging service. As a messaging service, for example, Twitter or the like may be used. In Twitter, tags may be included, and the tags may be hashtags. If the event is a traffic jam, information about the traffic jam that occurred around the vehicle is included in the tag and shared, so that a third party who sees the tag can more reliably receive information about the traffic jam.

In addition, as the position information, the user can specify a specific position where an event that may hinder the progress of the vehicle is occurring, such as latitude and longitude information, the name of a municipality, the name of a landmark, or the name of an intersection. Content can be included in a message and then shared with other users through posting to a messaging service. If a third party wants to know the traffic congestion related to the event, it is conceivable that the third party may search by specifying at least one of latitude and longitude information, the name of the municipality, the name of the landmark, and the name of the intersection. Get to your messages easily.

Users can also include tags generated based on location information in messages and share the messages with other users through postings to messaging services. The tag generated based on the position information may be, for example, a city/town/village name, a road name, or a landmark name. A third party can easily search for messages related to predetermined location information by using the tag. For example, it is conceivable that it becomes easier to communicate with a person who has a message in the same area. If the event is a congestion, then a tag related to congestion may be generated. In this way, third parties can retrieve messages related to congestion and location information.

Also, the user sends a message including at least one of the type of event, information related to the time when the event occurred, the road name of the road on which the event occurred, and the address on which the event occurred to the messaging service. You can share it with other users through posts. The information related to the time when the event occurred is not limited to the time when the event occurred, but may include, for example, the time elapsed since the event occurred. Also, the name of the road on which the event occurred may be, for example, a numerical representation such as National Highway X, or a street name such as ○○ Street. Also, the address where the event occurred may be, for example, the name of the prefecture or the name of the municipality, but may also include the name of the town or street address. Information based on the generated address may include, for example, facility names and landmark names. Examples of facility names and landmark names include facility names such as government offices (municipal government offices, police stations, fire departments, etc.), stations, airports, PA/SA, parks, amusement parks, shopping malls, gas stations, etc. Good.

In addition, when the user includes in the message the type of the event that occurred, information related to the time the event occurred, the road name of the road on which the event occurred, and the address on which the event occurred, the user can add tags to the message. Once included, the message can be shared with other users through posting to a messaging service. In particular, road names and addresses are tagged and included in the message based on the knowledge that they are easily used in searches using tags. This makes it easier for a third party to use the tag handled in the messaging service to display and confirm the message in association with the road name and/or address.

[1.4.3 Example of posting vehicle status other than congestion]
This embodiment is an embodiment in which a message is generated and posted when, for example, the vehicle is in a state other than traffic congestion, such as when the vehicle is driving at the tail end, or when the vehicle has passed through an enforcement point.

For example, the control unit 100 acquires images captured by a drive recorder connected via the communication unit 146 . Then, the control unit 100 (timing determination unit 108) analyzes the image to detect that tailgate driving has occurred as a trigger. Then, the message generation unit 104 generates a message indicating that there was tailgating.

Further, when the control unit 100 (timing determination unit 108) receives the radar for crackdown from the radar receiving unit 140, the crackdown may be detected as a trigger. The message generator 104 generates a message indicating that crackdowns are being carried out.

In addition, the timing determination unit 108 may detect the trigger according to the state of the vehicle 50 in addition to this. A message generator 104 generates a message according to the trigger. For example, the message generation unit 104 may generate a message to that effect when receiving a police radio, or when receiving a car location radio from a police car.

Also, the control unit 100 acquires and analyzes an image captured by a drive recorder connected via the communication unit 146 . Then, when it is detected that crackdowns are being carried out as a result of analyzing the image, a message to that effect may be generated.

Thus, according to this embodiment, information other than traffic congestion can be easily shared with other users via the service (messaging service). In particular, by using the service, it is possible to share information immediately about situations that are "currently occurring" such as tailgating. For example, if you know that there is a car that is driving tailgate, you can avoid trouble in advance by changing the driving route or stopping driving (for example, taking a rest at a facility).

Also, when tailgating, a message including an image of the tailgating vehicle may be generated and posted to the service. Other users who read the message can avoid trouble in advance by avoiding the vehicle when it arrives.

Also, for example, if the vehicle is hit-and-run or hit-and-run, a message including an image of the vehicle may be generated and posted to the service. By sharing the image in the service, the vehicle in the image can be found, and other users can report it, thereby solving the problem.

In this way, the information about the image taken outside the vehicle can be included in the message, and the message can be shared with other users through posting to the messaging service. The outside of the vehicle preferably includes at least one of the forward, rearward, and lateral directions of the vehicle, and preferably includes the forward direction. A third party can visually confirm to what extent the condition has occurred if the image shows a situation in which an event that may cause the vehicle to be hindered from proceeding is captured. If the event is a traffic jam, it is preferable to photograph the outside of the vehicle, particularly the area in front of the vehicle. In this way, a third party can visually confirm how much the state is occurring from a congested train or the like. Here, the imaging device may be provided in the electronic device, but may be configured separately from the electronic device. For example, the electronic device may be equipped with a camera that captures the front of the vehicle. Alternatively, an image from a drive recorder installed in the vehicle may be used. Alternatively, a camera provided in a smartphone or other information processing device owned by the user may be used.

Users can also share messages with other users through postings to the messaging service, indicating at least the type of event that has occurred, such as tailgating, crackdowns, road closures, or dangerous driving. For the type of event that occurred, the type of event that occurred may be set as a category.

[1.4.4 Example of Posting Messages by Combining Multiple Vehicle Conditions]
This embodiment is an embodiment in which the message generation unit 104 generates a message by combining the traffic congestion state and other states.

For example, when the control unit 100 detects that another vehicle has cut in front by analyzing the image of the drive recorder or the detected acceleration, it further generates a message such as "Mumm, mumm, cut in". may In addition, the message generating unit 104 may post an image captured at that time (an image showing the vehicle that cut in) included in the message. For example, about 47% of drivers have experienced behavior such as rush driving due to frustrated driving. Therefore, by intentionally posting the situation as a message, it is possible for the driver to restrain himself/herself.

Thus, it is possible to post a message to the service from the electronic device 10 as described in the above embodiments. Events related to traffic information such as traffic accidents, traffic jams, road closures, dangerous driving (reversing driving, reverse driving), fires and floods, as well as events related to enforcement information such as traffic enforcement by radar, laser, police motorcycles and masked police cars are electronically recorded. It is possible to post to the service from the device 10 .

Note that, as described in the second embodiment, the management device 20 may be included between the electronic device 10 and the service (service providing device 30). Electronic device 10 transmits character data (posting information) and image data to management device 20 in order to generate a trigger for posting. Management device 20 may generate posted message information based on character data and image data and post it to the service.

The content of the message posted at this time is generated within a range determined by the service provider. For example, if there is a constraint of 140 characters or less, it is generated within 140 characters. Also, the message posting unit 105 posts messages so as to conform to the rules of the service provider. For example, if the service provider stipulates that the posting interval should be 10 minutes and that the same content should not be posted, messages are posted according to the rule.

Also, the message generation unit 104 may post a message with a predetermined fixed phrase. Also, the message generation unit 104 may generate an arbitrary message based on input from the user (for example, voice input).

Thus, according to this embodiment, it is possible to determine a plurality of states from the state of the vehicle, generate a message, and post it. This allows other users to obtain multiple pieces of information in real time via the service. In addition, since a message is generated based on the state of one or more vehicles 50, by following a user who posts information necessary for other users, necessary information can be acquired as appropriate. is.

[1.4.5 Example of posting a message at an arbitrary timing]
This embodiment is an embodiment in which trigger detection is performed at a user's (eg, driver's) arbitrary timing.

For example, the body portion 10100 may be provided with a physically operable operation button. For example, as shown in FIG. 10, an operation button 1502 is provided on the main body part 10100 . When the user selects operation button 1502, timing determination unit 108 detects a trigger. As a result, the message generation unit 104 generates a message, and the message posting unit 105 posts the message to the service.

At this time, when the operation button 1502 is selected, the message generation unit 104 may generate and post a predetermined message, or generate a message according to the state of the vehicle 50 at that time. good too.

For example, when the operation button 1502 is selected by the user, the message generation unit 104 may generate a message indicating traffic congestion, such as "currently in traffic", if the vehicle 50 is in traffic. Accordingly, by operating the operation button 1502, the user can post a message according to the situation to the service.

Also, the characters associated with the operation button 1502 may be posted to the service each time. For example, every time the operation button 1502 is selected, "I found dangerous driving" may be posted to the service. In this case, control unit 100 may post a message including the state of vehicle 50 when operation button 1502 is selected. For example, the current position of the vehicle 50 or an image of an external drive recorder may be transmitted each time.

Also, an operation button may be provided for each function. For example, in FIG. 10, an operation button 1502 and an operation button 1504 are provided. In this case, the type of message to be posted may be changed for each operation button, or the type of message to be posted may be changed. For example, in FIG. 10, by selecting the operation button 1052, the message generation unit 104 generates a message about congestion. Also, when the operation button 1054 is selected, an image currently captured by a drive recorder or the like is included in a message and transmitted.

Also, since it is difficult to send a message while driving, the operation buttons described above may be provided with a "voice tweet button", a "video tweet button", and a "photo tweet button". This allows the user to switch and send a plurality of messages with a simple operation. With such operation buttons, for example, when a user encounters an accident scene or a fire scene, the user can quickly take a picture and post a message.

Further, the control unit 100 may detect a touch operation input from the touch sensor 152 as a trigger for generating a message. For example, the control unit 100 displays software buttons on the display unit 120 . Control unit 100 may generate a message by detecting that a software button has been touched by touch sensor 152 .

Also, the control unit 100 may display one or more candidates on the display unit 120 . Then, a message may be generated according to the candidate selected by the user.

Further, when the touch sensor 152 detects a predetermined operation, the control unit 100 may detect it as a trigger for generating a message. For example, it may be detected that a trigger for generating a message is input by tapping the touch sensor 152 three times by the user.

Also, the control unit 100 may receive the trigger from the user by an input method other than the operation button. For example, the control unit 100 may detect that a trigger for generating a message has been input due to voice input through the microphone 154 . At this time, the control unit 100 may simply detect a volume equal to or higher than a predetermined value as a trigger, or may detect a predetermined voice command as a trigger.

Further, when a voice is input, the control unit 100 may include characters recognized from the voice in the message. Further, when the voice is input, the control unit 100 may attach the input voice data itself to the message and generate the message.

Also, the control unit 100 may recognize a user's motion. For example, it may be detected that a user waves his or her hand in front of the electronic device 10 to input a trigger for generating a message.

Thus, according to this embodiment, the user can post a message at any timing. As a result, information that the user considers necessary can be shared with other users via the messaging service each time.

In addition, in the above-described embodiment, the timing for generating a message can be input not only by touch operation but also by voice operation or gesture operation. Thus, messages can be generated and posted to the service on the fly without disrupting driving.

In addition, the user can more accurately identify the type of event that actually occurred, and share the message including the type of event with other users through posting to the messaging service. The event type options may include event options that the user is likely to encounter, such as congestion, accidents, and speed control. For example, when the user wants to post a message about "accident" at any time, he or she can post a message containing the word "accident" by selecting "accident".

In addition, when the user selects an event, the user can select using a touch panel or voice recognition, and the user can select the event in a simple manner. The touch panel or the voice recognition device may be provided in an in-vehicle device arranged in the vehicle. In this way, it is easy for the user in the vehicle to operate. Under the configuration of selecting by voice recognition, for example, when the user is driving, by using voice recognition, an event can be easily selected without releasing the hand. Therefore, the user can operate the device while paying attention to safe driving.

In addition, by selecting an operation button, the user can share a message regarding the state of the vehicle corresponding to the operation button with other users through posting to the messaging service. Also, this operation button is preferably provided independently of the button for generating and posting a message. This makes it difficult for the user to get lost in the operation. In addition, it becomes easier for the user to easily share the information that the user has determined to share with other users via the messaging service. The operation button may be a soft button displayed on the display screen, but may be a physical button.

In addition, the user can share a message regarding the state of the vehicle corresponding to each operation button of the plurality of operation buttons with other users through posting to the messaging service. For example, an operation button may be assigned to each event, or an operation button may be assigned to each message to be generated. For example, a first button may be assigned the function of simply generating a textual message, and a second button may be assigned the function of generating a message with a picture (e.g., including a picture of the front of the vehicle). .

In addition, users can easily create messages about "accidents" and "traffic jams," which are likely to be encountered while using a vehicle, and share them with other users through posting to messaging services. can be done.

Also, a message can be generated based on voice input from the user, and the message can be shared with other users through posting to the messaging service. The voice input from the user may be voice uttered by the user. A message may be generated by triggering the recognition of the voice uttered by the user. For example, an event message may be generated and posted in association with a predetermined keyword uttered by the user (for example, "dangerous" or "crowded"). Although the message may contain a predetermined keyword uttered by the user, it is easier for a third party to comprehend if a message describing an event inferred from the keyword is generated. Also, a message may be generated when the volume of the input user's voice is equal to or higher than a predetermined volume. Alternatively, speech recognition may be performed based on the input speech, and a message may be generated including the result of speech recognition.

A user can also include the audio itself in a message and share the message with other users through posting to a messaging service. Users can post messages more easily by including the audio itself in the message. As a messaging service, for example, Twitter as a social networking system may be used. Since Twitter has a function of posting voice messages, it is recommended to use this function.

[1.4.6 Example in which Predetermined Keyword is Included in Message]
This embodiment is an embodiment in which a message is generated including a predetermined keyword. The message generation unit 104 generates a message by attaching a predetermined keyword to the message, like a signature. Here, the message generation unit 104 may store the keyword attached to the message in the storage unit 190 as setting information.

Here, the predetermined keyword may be, for example, a user name or a vehicle name. Alternatively, the manufacturer name or model name of the electronic device 10 may be used. In the case of the manufacturer name and model name of the electronic device 10, they may be stored in the storage unit 190 in advance. In addition, the manufacturer name and model name of the electronic device 10 may be stored in advance at the time of shipment. Further, in the case of the manufacturer name and model name of the electronic device 10, the user may not be able to change them.

For example, a message is generated by adding "#transmitted from Jupiter radar detector" to the message. This allows other users to recognize that the message is being sent from a Jupiter radar detector. Also, the above-mentioned message may be generated with one line blank (including a linefeed code that results in a blank line). That is, as a specific keyword, the company name of the manufacturer of the electronic device 10 or the product name may be displayed so as to be distinguishable from other message contents.

Also, the predetermined keyword may be added to each message, or may be added to the message at predetermined intervals. For example, the message generation unit 104 may include a predetermined keyword in the message at the timing of generating the first message, or may include it at each frequency (for example, every five times) or time (for example, every hour, morning, noon, etc.). , in the evening)).

Also, the predetermined keyword may include a command. For example, the command "<location>" is included in the keyword. In this case, the message generation unit 104 may generate a message by replacing “<location>” with the current location of the vehicle 50 (latitude/longitude information, address, road name, etc.).

According to this embodiment, it is possible to include a predetermined keyword in a message and post it to the service. Therefore, for example, by using the company name as a keyword in the case of one's own shop or a business vehicle, an advertising effect can be expected.

In addition, it is possible to inform other users of the manufacturer name and/or product name of the in-vehicle device that has been posted, while making it possible for other users to know what the vehicle status message is. For example, it is possible to expect merits on the side of sellers such as an increase in recognition and sales promotion of in-vehicle equipment sellers, such as an appeal to young people with many SNS users and an expectation of increased purchase desire.

In this way, the user can take a questionnaire for third parties through the in-vehicle device. As a messaging service, for example, Twitter as a social networking system may be used. Since Twitter has a questionnaire function, it is good to use it. The questionnaire function may be realized by directly using a message or the like. By executing a questionnaire function, for example, a questionnaire may be conducted to confirm whether or not a message posted by a user is correct with a third party, and the message may be evaluated by the questionnaire. The contents of the questionnaire by the questionnaire function may be manually set by the user, but may be determined without such setting. For example, the content of the questionnaire may be determined according to the state of the vehicle. For example, when it is determined that traffic congestion is occurring, a questionnaire function is executed to determine whether it is better to select a route with traffic congestion or a route that avoids traffic congestion. It is advisable to confirm this with a questionnaire.

Moreover, after including a predetermined keyword in the message, the message can be shared with other users through posting to the messaging service. The predetermined keyword may be, for example, a message that the user always wants to include in the message, or a message that includes greetings. Predetermined keywords may include, for example, an announcement of the user's store, a link to the user's profile page, and the like. As for the predetermined keyword, when the user always attaches a predetermined tag, the tag may be set in advance as the keyword. The predetermined keyword may be manually specified by the user, or may be determined by the in-vehicle device and inserted without user's specification.

It should be noted that setting in advance means that the same keyword is always used while using the in-vehicle device, instead of being input each time. Therefore, the keyword may be stored at the time of shipment from the factory, or may be stored as setting information in the in-vehicle device.

Also, the message may include the manufacturer name and/or product name of the device that acquires the vehicle status, and the message may be shared with other users through posting to the messaging service. Since the third party thinks that the same function can be realized by using the product, it can be expected that the third party will be motivated to purchase the same product. As the device for acquiring the state of the vehicle, it is preferable to use a drive recorder, a navigation system, a detector (for example, a radar detector, a laser detector), etc. as described above. In each message, insert the manufacturer and product name of the device that acquires the vehicle status. By doing so, a higher advertising effect can be expected. In addition, for example, since the fact that the manufacturer name and/or product name of the device is used becomes clear, a third party can understand that the message is posted from the device, and the reliability of the message is confirmed. It can be expected to be recognized as high.

In addition, the manufacturer and/or product name of the device being used by the user may be communicated to third parties through postings to the messaging service, while allowing other users to know which vehicle status messages are. can be shared. For example, users of SNS such as Twitter as a messaging service and as a social networking system are mostly young and purchasing. It is possible to expect merits on the side of the seller, such as improved quality and sales promotion.

[1.4.7 Example of outputting a message according to an acquired message]
This embodiment is an embodiment in which the message output unit 107 outputs a message based on the obtained message information obtained by the message obtaining unit 106. FIG.

The message acquisition unit 106 acquires acquired message information including one or more messages from the service and stores it in the message information storage area 196 .

At this time, the message acquisition unit 106 may acquire the message based on a predetermined keyword. For example, the message acquisition unit 106 may acquire a message containing any of the words "place name" and "accident" as keywords. In addition, the message acquisition unit 106 can detect traffic conditions such as “accident congestion”, “traffic congestion”, “dangerous driving”, “push driving”, “single accident”, “multiple accidents”, “reverse driving”, “#accident congestion”, and “#traffic congestion”. As information related to traffic information, a message likely to be related to traffic information may be acquired. That is, traffic-related keywords may be acquired.

The traffic-related information (traffic-related keywords) may be related to traffic events that the user should consider while traveling in a vehicle, particularly information related to traffic congestion, information related to safe driving, or the like. For example, the information may include keywords related to traffic congestion such as "traffic jam", "accident", and "under construction", and keywords related to safe driving such as "policing", "reverse driving", and "wind driving".

In particular, the messaging service may be a social networking service (SNS), and the electronic device may have a function of obtaining traffic-related information from messages of the social networking service. In this way, the user can receive traffic-related information among many messages handled by the social networking service. Information related to traffic may be information related to the use of vehicles. In this way, the user can receive information related to the use of the vehicle. As for the use of a vehicle, it is particularly preferable to drive the vehicle.

Also, the message acquisition unit 106 may acquire a message containing a predetermined keyword as a "tag". For example, messages containing tags such as "#accident" and "#Tomei expressway" may be obtained.

For example, a keyword or tag related to the message may be obtained separately from the message. Or you might include the tag in the message, so get that message. At this time, by using this tag, a keyword or tag related to the message may be acquired separately from the predetermined topic message, but the predetermined topic may be a topic related to traffic. The messaging service may be, for example, Twitter (registered trademark) as a social networking service. The tag should be a hashtag, and it is better to use what is included as part of the content of the tweet.

A configuration may be adopted in which messages posted by other users are periodically obtained from the messaging service. In this way, the user can use the system as if he were receiving traffic information. If you want to fetch messages on a regular basis, you may want to fetch messages based on tags. For example, if a tag indicating "#congestion" is used as a traffic-related tag, a message including "congestion" is displayed periodically, so that the user can use the system as if he were receiving traffic information.

Also, the message acquisition unit 106 may acquire the message based on the location information. For example, the position information of the electronic device 10 may be used as a reference, and messages within a predetermined range of distance may be acquired. At this time, the message acquisition unit 106 acquires the message based on the location information together with the keyword described above.

Also, the message acquisition unit 106 may acquire the message based on the state of the vehicle. For example, the electronic device 10 acquires vehicle information via OBDII. Then, the message acquisition unit 106 identifies a keyword based on the vehicle information and acquires messages containing the keyword. For example, the message acquisition unit 106 acquires the voltage of the vehicle from OBDII and identifies a keyword according to the voltage. For example, the specified keyword may be a state such as "voltage is low" or a voltage value such as "12.0V". In addition, the message acquisition unit 106 may use keywords for engine-related information such as oil temperature, turbo pressure, and water temperature, or keywords for travel-related information such as idling stop time and average running time.

In addition, the message acquisition unit 106 may change the range acquired from the position information according to the number of acquisitions. When the message acquisition unit 106 acquires messages based on location information, the message acquisition unit 106 may change the range of message acquisition based on location information so that the number of messages reaches a predetermined number. For example, if the number of acquired messages is 20 or more, the range of message acquisition based on location information may be expanded until the number of acquired messages reaches 20 or more. For example, the position information may be extended from the current acquisition position to 1 km, 5 km, and 10 km. In addition, the area such as adjacent municipalities or prefectures may be expanded.

Also, the message acquisition unit 106 may narrow the range when the number of acquired messages is too large. For example, if the message acquisition unit 106 acquires a threshold value or more (for example, 20 or more) when acquiring messages, the range of location information acquisition may be narrowed to less than 20 messages.

Also, the message acquisition unit 106 may change the range of message acquisition so that the number of displayed messages is within a predetermined range. For example, the range from which the message is acquired may be represented by the distance of the peripheral range centered on the target person's position. Also, for example, the range of message acquisition may be contents such as the age group and sex of the account, the type of car of the installed device, and the attributes of the message.

For example, in the case of information about traffic jams, it is preferable to output a message near where the vehicle is located or to output it preferentially. Preferential output may be output in a manner in which the preferentially output message is easily perceived by the user. Alternatively, the message to be output preferentially should be output earlier than other messages in terms of time, or the message to be output preferentially should be displayed in a more conspicuous position than other messages. . Also, it is preferable to adjust the size of the peripheral range so that the number of acquired message information items is included in the predetermined range. For example, if the number of message information items is 30, a range based on the position information may be specified so as to be included in the 30 items. For example, when the number of acquired messages exceeds the range of 20 to 30, the control unit may perform control to reduce the size of the peripheral range. Also, if the number of acquired messages is less than 20 to 30, control should be performed to increase the size of the peripheral range.

Further, the size of the peripheral range may be changed simply by the distance from the center, or may be changed according to the traveling direction of the vehicle, for example. In the latter case, for example, the peripheral range in the traveling direction of the vehicle may be widened. For example, when the vehicle is traveling north on an expressway, the area on the north side in the direction of travel may be expanded. In this way, it is possible to obtain messages related to the direction in which the user is going.

Also, when outputting the acquired message, the output mode may be changed. The user can confirm the relationship between the position where the message was posted and the position with respect to the user by the change in the output mode of the displayed message. For example, a message posted from a position close to the position of the device may be displayed by changing the color, changing the character size, or adding a symbol. In this way, the user can confirm that the content of the message is what is occurring nearby. In addition, it is preferable to change the priority of outputting messages in conjunction with changing the output mode, or instead of changing the output mode. For example, messages within a predetermined distance from the position of the electronic device may be preferentially output.

Note that if the search interval (interval at which messages are acquired) by the keyword is short, the message acquisition unit 106 may impose a load on the service or violate the terms of service providers. Therefore, it is preferable to obtain the messages with a certain interval between them. The interval at which messages are acquired may be, for example, within a range defined by the service provider.

Then, the message output unit 107 outputs the message acquired by the message acquisition unit 106 . Specifically, the message output unit 107 acquires the message on the display unit 120 .

For example, FIG. 11 is an example of a display screen displayed on the display unit 120. As shown in FIG. For example, as shown in FIG. 11A, the message may be scroll-displayed in a partial region R100 of the display screen W100. The message displayed in region R100 may be superimposed on the display screen that is normally displayed, or may be displayed in another region. Also, the message in the area R100 may be horizontally scrolled (for example, displayed moving from the right end to the left end of the display screen W100).

Further, as shown in FIG. 11B, an area for displaying a message may be provided in a partial area R110 of the display screen W110. For example, the region R110 may be vertically scrolled to display messages. Specifically, the area R110 may display new messages on the upper side of the screen and scroll down older messages.

In addition, the message output unit 107 may display attributes of the message when outputting the message. For example, the message output unit 107 outputs not only the message, but also the account name and account ID, as well as the number of ratings (number of likes, number of likes), number of reposts (number of retweets), , the presence or absence of replies (the number of replies) may be displayed. Further, in the case of an official account, the message output unit 107 may also display that it is an official account.

Also, the message output unit 107 may display these together with pictograms and symbols. For example, when displaying the number of likes as the number of evaluations, the number of likes may be displayed together with a heart pictogram.

11C and 11D are examples of display screens actually displayed on the electronic device 10. FIG. In FIG. 11C, the map is displayed on the display screen, and the message is displayed as it is on the lower side. This message is displayed so as to flow from right to left on the display screen. Also, if the message includes pictograms, the pictograms may be displayed together. By displaying pictograms, the user's emotions can be expressed along with the message. For example, by displaying an "angry face", you may express that you are irritated. Also, by displaying a "crying face", you may express that you are in trouble. In addition, the pictogram of "police car" may be displayed to indicate that there is a crackdown, or the pictogram of "construction" may be displayed to indicate that construction is underway. By including pictograms in the message in this way, the user can provide a highly visible message.

The pictograms used here may be the same pictograms used in the service. By displaying pictograms used in the service as they are, it becomes easier for the user to convey the situation (for example, the feelings of the poster).

FIG. 11D displays a message generated by the electronic device 10, for example. In this case, a display may be made to identify that the message is obtained from the service. For example, by changing the color of the message, the message obtained from the service and the message generated by the electronic device 10 may be displayed so as to be distinguished from each other. Also, as shown in FIG. 11D, the elapsed time from the first time when the event was acquired may be displayed together. Also, as shown in FIGS. 11C and 11D, the display screen may display, for example, the speed of the vehicle, the current time, the address corresponding to the current position, and the name of the road on which the vehicle is traveling. Also, other vehicle information may be displayed according to user settings.

Also, the message output unit 107 may display the message repeatedly. For example, when the obtained messages stored in the message information storage area 196 are telop-displayed (scroll-displayed), they are repeatedly displayed. For example, when there are 10 acquired messages, the message output unit 107 may sequentially display the oldest message from the first one, and after displaying the tenth message, may display the first message again.

Also, the message output unit 107 may switch the display speed depending on the number of messages to be displayed. For example, the scroll speed may be increased when there are many messages, and decreased when there are few messages. That is, the message output unit 107 may adjust the number of outputs to be displayed per unit time.

Also, the message output unit 107 may change the display mode of the message according to the state of the vehicle. For example, the message output unit 107 may acquire vehicle information by OBDII via the terminal unit 172 . For example, the message speed may be switched according to the speed of the vehicle based on the vehicle information.

Also, the message output unit 107 may switch the display speed between the most recent message and the past message.

Also, the message output unit 107 may change the output mode (display mode) according to the attribute of the message. For example, if the number of evaluations and reposts for a message is large, the display speed of the message may be slowed down, and if the number of evaluations of the message and the number of reposts is small, the display speed of the message may be increased. Also, instead of changing the display speed of the message, the message output unit 107 may change the color of the message or change the size or type of font. In addition, the message output unit 107 may change the output mode of, for example, a reply message (when the own account is included in the reply destination) as a message attribute.

In this way, the user can receive the message addressed to him/herself in an output manner different from that of other messages, thereby making it easier to check the message addressed to himself/herself. As for the message addressed to the user, it may be provided with a function of extracting from among the messages obtained from the messaging service, but may also be provided with a function of separately obtaining only the message addressed to the user.

Here, the message addressed to the user's account means, for example, that the message includes information about the second account, that the message includes a mention addressed to the second account, or that the message includes a mention of the second account. It is good to say that there was a reply to a message posted from the account of

Users can receive messages that mention their account in the message. Also, for example, it is preferable to have a function to change the output mode of a message referring to the user's account in the message. In this way, the user can receive messages in which he is mentioned. Here, the message referring to the user's account is, for example, information indicating the user's own account in the message (for example, it may be the same as the above-described information indicating the account, such as an identification ID). It should be a message that Also, the messaging service may be, for example, Twitter, which is a social network service, and the message referring to the user's account may be a message mentioning the user.

Also, in the above embodiments, the user can see not only the message, but also the attributes of the message. The attribute of the message may be an attribute that serves as an index of the degree of importance of the message. Such an attribute may be, for example, an attribute relating to location or an attribute relating to message rating. By outputting the attributes of the message together with the message, the user can determine the importance of the message according to the content of the output message and the attributes of the message.

In addition, as an attribute corresponding to the message, the user may specify at least one of the number of times the message has been reposted, the number of times the message has been replied to, and the number of times the message has been evaluated, together with the message. can receive. These attributes may be displayed together with the message, or these attributes may be output by voice together with the message. In this way, the user can grasp the number of times the message has been reposted, the number of times the message has been replied to, and the number of times the message has been rated as ratings for the message.

Here, it is preferable that the messaging service is, for example, Twitter, which is a social network service. In this case, the number of times the message has been reposted may be the number of retweets, the number of times the message has been replied to may be the number of replies, and the number of times the message has been rated may be the number of times it has been "liked." It is preferable that the attribute is obtained by accessing the API provided by the messaging service via the network.

For example, it is preferable to output "X number of retweets have been made" along with the message. In this way, the user can grasp not only the message but also the number of times it has been reposted. For example, the user can infer that the more frequently a message is retweeted, replied, or the like, the more people have instructed the message, and the more reliable the message is.

Also, for example, when the number of messages is large, it is preferable to increase the scroll display speed of the messages. In this way, the user can confirm many messages. In addition, for example, by viewing messages that are scrolled at a high speed, the user can not only understand that the number of posts is large, but also obtain a sense of realism (for example, an image of a large amount of information flowing). be able to. Also, if the number of acquired messages is small, the scroll display speed should be slowed down. When the scrolling display speed is slow, the user can not only understand that the number of acquired messages is small, but also can easily check the messages and feel calm.

Also, the user can recognize the number of messages depending on the message output method. For example, if the number of messages acquired per unit time is large, the output method should be to output messages quickly, and if the number of messages acquired per unit time is small, the output method should be to output messages slowly. In this way, the user can understand that many messages can be obtained per unit time if the messages are output quickly. Also, the user will know that if the messages are output late, fewer messages will be retrieved per unit time. Also, as a method of outputting the message, when changing the speed, for example, the scrolling speed may be changed, but it is preferable to change the display speed of the telop.

Also, the message output unit 107 may change the display mode when the account that posted the message is an official account or a corporate account.

Also, if the content of the message or the location information included in the message is close to the location of the electronic device 10, the message output unit 107 may change the display mode.

Also, the message output unit 107 may switch the timing of outputting the message according to the state of the electronic device 10 . For example, the message output unit 107 may output a message (display a message) when the vehicle 50 equipped with the electronic device 10 is stopped or moving at a low speed.

In addition, the message output unit 107 may stop the voice output when music or radio is playing inside the vehicle 50, for example, when voice output is performed. Further, by setting, the message output unit 107 may output the message with a louder volume than usual when the vehicle 50 is running and the noise is loud.

As described above, according to this embodiment, it is possible to obtain not only messages but also messages as needed. In the service, a simple search will extract many messages. Therefore, it is possible to obtain a message according to need and to display the necessary message in a different display mode.

According to this embodiment, the user can receive messages from the messaging service that include traffic-related keywords among the messages. Although the messaging service includes messages posted by users other than the user, it is preferable to have a function of obtaining messages including keywords related to traffic from messages posted by other users. Also, it is preferable to have a function not to acquire messages that do not contain traffic-related keywords from the messaging service. In this way, the output messages can be narrowed down to messages containing traffic-related keywords, and the user can avoid receiving messages that do not contain traffic-related keywords from the messaging service.

As a messaging service, for example, Twitter (registered trademark) as a social networking system may be used. In Twitter, a message posted by each user is also called a tweet, and is created and distributed by a user using the service. It may be provided with the ability to periodically retrieve messages from the messaging service via an API. Also, it is good to get messages in real time. In this way, the user can obtain messages containing keywords related to transportation from the messaging service in real time.

A user can receive a message on an electronic device that includes traffic information from a messaging service. As a method for an electronic device to output a message to a user, for example, if the electronic device has a display device or a voice output device, the display device displays traffic information based on the message, A voice output device may output traffic-related information based on the message.

In addition, according to the present embodiment, it is possible for the user to easily grasp the information regarding the account that posted the message according to the output mode of the message. For example, it is preferable to have a function of displaying a message on the display unit as the output destination of the message, and it is preferable to change the display mode such as the color of the message, the size of the font, and the type of the font. In this way, the user can easily determine the information about the account and easily grasp the information. Specifically, for example, in the case of an account related to a user, it is preferable to change the font color and display it. Also, for example, it is preferable to change the size of the message or change the color of the message according to the number of accounts related to the account that posted the message (number of followers/number of followers).

Also, when the user views the message, the user can also view the displayed pictogram. In addition, at this time, the user can also view the pictogram displayed by the messaging service as it is on the electronic device. Emojis may be used to express emotions and states. In addition, since the same pictogram used by the user is displayed on the messaging service and on the electronic device, the user can receive the message more easily. When displaying pictograms as they are, the control unit may display pictograms having the same appearance, or may display pictograms that mean the same content even if the pictograms have different appearances. For example, for pictograms of "smiley face", it is preferable that the character codes indicating the pictograms are at least the same.

[1.4.8 Example of Outputting Required Messages Among Acquired Messages]
A present Example is an Example which hides a message as needed among the acquired messages. Since there is a lot of useless data in the acquired messages, it is preferable to extract the appropriate messages.

For example, when the message acquired based on the keyword is a reposted message, the control unit 100 (message output unit 107) may display only one message and may not display the rest.

for example,
"@NEX <Closed due to fire> Tomei Expressway Down line 195.5 KP vehicle fire, closed between Yoshida IC and Sagara Makinohara IC"
There is a message, and as a repost of the message,
"RT @NEX <Closed due to fire> Tomei Expressway Down line 195.5KP vehicle fire, closed between Yoshida IC and Sagara Makinohara IC"
If there are multiple "RT" messages, the message containing "RT" may be hidden. In addition, the message output unit 107 may display all the messages, assuming that many reposted messages are important messages.

Also, the message output unit 107 may perform identification display on the first message. For example, the message output unit 107 may change the color or font of only the first message. In addition, the message output unit 107 may also display the number of reposts. Also, if the message output unit 107 cannot acquire the first message (message without RT), the message output unit 107 may display only the oldest message among the acquired messages. Further, the message output unit 107 may display a reposted message at a predetermined timing among the reposted messages. For example, the message output unit 107 may display every 5 minutes or every 10 of the acquired messages.

Also, the message output unit 107 may preferentially display a message with a high evaluation score (a message with a large number of likes). Also, the importance of a message may be determined by using a learning model learned by machine learning from these message wordings and attributes.

In addition, the message output unit 107 may not display messages that have little relevance. In this case, the hidden keyword may be set in advance, or may be registered by the user. For example, keywords such as "large public bath", "sexual activity", and "tasting" may be registered, and messages containing such messages may be hidden or may be displayed only once.

In addition, the message output unit 107 may not display a message including an itemized list.

Also, the message output unit 107 may not display messages that are not in the traveling direction. For example, assume that the vehicle 50 is traveling on the Tomei Expressway from Tokyo toward Nagoya in the down direction. At this time, the message output unit 107 outputs information about Shizuoka Prefecture and Aichi Prefecture when the vehicle is traveling in Shizuoka Prefecture. Also, the message output unit 107 may not output information about Kanagawa and Tokyo.

In this way, since many messages are included in the service, if it is simply extracted, more messages than necessary will be output. can be done. Also, since the messaging service can be easily used by young people, it includes messages that generally do not need to be displayed, such as messages between friends. In this embodiment, by excluding such messages, more necessary information can be obtained and output.

[1.4.9 Example of Generating New Messages from Periodically Acquired Messages]
This embodiment is an embodiment in which the message acquisition unit 106 periodically acquires messages and generates new messages.

That is, the message acquired by message acquisition unit 106 is stored in message information storage area 196 . The message generator 104 generates a new message (posted message) from the messages stored in the message information storage area 196 .

Then, this newly generated posted message may be posted to the service by the message posting unit 105 . In addition, among the messages acquired by the message acquisition unit 106 at this time, the control unit 100 (the message generation unit 104 or the message posting unit 105) may generate related messages collectively as a message.

Here, the related message is a message determined by the control unit 100 to be similar to the message, a message associated in the service (eg, reply message (eg, reply message), or a reposted message (eg, , retweet messages).

Similar messages refer to, for example, messages containing the same wording to some extent. For example, if the type of event (keyword indicating category) and location (time of occurrence of event, road name, municipality) are common, the control unit determines that the messages are similar. Moreover, the control unit 100 may score the inclusion of a plurality of words, and determine that the words are similar when the score is high. For example, the control unit 100 determines that the messages are similar when the messages share the keywords "congestion" and "Hakozaki" and the posted times of the messages are different. Also, the control unit 100 determines that a message containing words common to those of a highly reliable account is a similar message. Also, the control unit 100 may determine whether the messages are similar by machine learning.

For example, the control unit 100 may add a link to the newly generated message so that a summary message in which related messages are collectively displayed can be displayed. By selecting the link, the user can see the original message or messages that created the new message. On the site where this summary message is displayed, related messages may be displayed as threads, for example. Also, the two-dimensional code of the site where this summary message can be displayed may be displayed together.

Also, the newly generated posted message may be output by the message output unit 107 . For example, a new message may be displayed on the display unit 120 or may be voice-outputted on the voice output unit 130 .

Here, a mechanism by which the message acquisition unit 106 acquires messages will be described. For example, the message acquisition unit 106 periodically acquires messages from services using predetermined keywords. For example, the message acquisition unit 106 may cyclically search all messages provided by the service and acquire messages that match the keyword. Also, messages matching the keyword may be obtained from messages (timeline of the user) of accounts related to the user's account (for example, the user's followers or accounts registered as favorites).

For example, traffic-related keywords are set as predetermined keywords (categories) for API search of services. A traffic-related keyword is a keyword related to traffic information or a keyword that is effective when driving a car. Specifically, keywords such as "traffic congestion", "accident congestion", "vehicle closure", "speed control", "dangerous driving", etc., are searched using these keywords as search keys.

Alternatively, a keyword (for example, "vehicle closed") may be used to compose a sentence using a pre-registered road name or a character string that matches the IC. That is, control unit 100 generates a new posted message.

Then, the message generator 104 acquires the event from the message and generates a message containing the event.

In addition, it is preferable that the new message from the message generation unit 104 includes a phrase related to any region. For example, it is preferable to include one or a plurality of phrases related to the area such as the name of the municipality where the event occurs, the name of the intersection, the name of the road, the name of the IC or SA/PA, and the section where the event occurs.

Categories corresponding to these keywords indicate types of events, and may be predetermined or may be added by the user. Moreover, a category may newly add an event. For example, if "pedestrian obstruction" is a hot topic in the news, the event type of "pedestrian obstruction" may be added as a new category.

An example of the message format in this case is shown in FIG. Examples of messages generated by this embodiment include, for example, "category", "time", "road name", "address", "mention", "hashtag", and "signature".

An example of the control unit 100 of this embodiment is shown in FIG. 12B, and an example of the configuration of the storage unit 190 is shown in FIG. The configuration of FIG. 12 is added to the configurations shown in FIGS. 8A and 8B.

The message control unit 109 generates a new message from the acquired message or the like, or processes the message. Also, at this time, using a dictionary database (DB) 199 stored in the storage unit 190, the message control unit 109 generates a message.

In this embodiment, when the user selects or inputs a category, the message control unit 109 generates a new message based on the message obtained from the service.

Here, the user inputs the category by voice input or selection by touch operation. Also, the user may input a category by operating an operation button. This is because in the case of the in-vehicle electronic device 10, characters cannot be typed in like a smartphone. Therefore, by selecting a category by voice or touch operation, a message (for example, a tweet article) is automatically composed. In addition, for the remaining messages other than the category, the content of each delimited frame is automatically generated using the location information (for example, GPS information by GPS) acquired by the electronic device 10 and the map information. can be done.

Also, for example, a standby screen for posting may be provided on the standby screen so that the user can easily post. For example, by taking a screenshot of the standby screen for posting, it can be posted as a posted image. Each item shown in FIG. 12A will be described below.

(1) Creation of categories It is preferable that the categories to be posted are phrases related to traffic. For example, it is preferable to list words that are easy to recognize by voice, such as "traffic jam", "reverse run", "tilt", and "police", and search words that are often used in messaging services. The categories may also match the keywords described above.

In addition, in the case of voice recognition, words that tend to produce score values may also be registered as registration words for voice recognition.

For example, in the case of "traffic jam", "jutai" may be registered in addition to "jutai". Similarly, if it is "closed", "Two Code Me" is registered in addition to "Tsukou Dome", if it is "reverse run", "Gyakuso" is also registered in addition to "Gyakuso", and if it is "runaway", "Boso" is also registered. Keep These are stored in the category dictionary 1982 of the dictionary DB 198 stored in the storage unit 190 shown in FIG. 12(C).

Also, a keyword corresponding to the category may be added. In this case, circulating keywords and keywords corresponding to messages are extracted and used as keywords. In this case, the keyword may be enclosed in parentheses to make it stand out, or may be enclosed in a command (eg, html tag) that can be identified later.

(2) Time The time managed by the electronic device 10 is used. At this time, for example, the date information of GPS or the time managed by the clock unit 103 of the electronic device 10 is used to automatically generate.

(3) Road name The road name is automatically generated by referring to the road dictionary 1988, for example. The road dictionary 1988 stores road link data, latitude/longitude, and road names in association with each other. The control unit 100 uses the name of the road on which the vehicle 50 is currently traveling based on the acquired position information (latitude and longitude information). Road names may be automatically generated.

(4) Address The address is automatically generated by referring to the address dictionary 1986, for example. The address dictionary 1986 stores map administrative boundary polygons, latitude and longitude information, municipality names, and town names. Then, the control unit 100 uses the address where the vehicle 50 is currently traveling based on the acquired position information (latitude and longitude information). The address may be automatically generated.

(5) Mention Mention includes the user account in the message so that, for example, the user who posted it can be identified. That is, a link (sometimes called a mention) to the user account is attached in the messaging service. Account information stored in the account information storage area 192 may be used for this user account.

In addition, third parties can view the user's profile page by linking to the user account. This leads to building a relationship of trust between the third party and the user who posted.

Also, the person who posts the message may be the account of the user using the electronic device 10, or may be the account associated with the management device when the message is posted via the management device or the like.

In addition, in order to indicate that a message has been posted to the user, it has been described that the mention to the user is included, but the posted message may be sent by direct message or e-mail.

(6) Hashtags Municipality names and road names are included in the message as hashtags. For example, a hash tag may be added with a specific character (string) to a character string of a municipality name or a road name. For example, by combining the specific character "#" and the road name "National Highway No. 1", the hashtag "#National Highway No. 1" is added to the message. Hashtags may be automatically generated. A hashtag is an example of a tag.

(7) Signature Any character string can be added as a signature. For example, by registering the name of the manufacturer of the electronic device 10 in advance, the technical capabilities of the manufacturer of the electronic device 10 can be appealed. Also, a character string arbitrarily created by the user may be added each time as a signature.

In this way, by circulating messages and describing them collectively, a new message is generated that is easier to understand than when the message is simply displayed.

The items (1) to (7) described above may be configured so that the user can select items to be included in the message. For example, (6) may not be included in the message. Also, the order in which messages are generated may be changed.

Also, the message generator 104 may include the number of related messages when there are multiple related messages. For example, the message generator 104 may display "There are 10 other messages regarding the accident of XX".

Moreover, when this number is displayed, this number may be the number of summarized messages.
In this case, when the user selects the number of messages included in the message or selects the link included in the message, a page may be displayed for confirming the summary message.

Also, a plurality of messages may be grouped by event or grouped by region. For example, a message such as "There are XX messages regarding accidents" or a message such as "There are XX messages in the vicinity of Nagoya Station" may be generated. Also, messages with the same event may be grouped together. For example, a message such as "There are XX messages regarding traffic jams at Chuo Expressway Rigging Slope SA" may be generated.

Also, the newly generated message may include part of the acquired message. For example, it may include the most recent messages, messages posted by trusted accounts, or portions of highly trusted messages. Another embodiment will explain whether the account or message is highly reliable.

As described above, in this embodiment, the message can be processed and displayed according to need without obtaining the message as it is. In particular, many messages are posted to messaging services, and there are necessary messages and unnecessary messages. Moreover, even a seemingly necessary message may be, for example, a mere repost message (retweet), and only a part of the necessary information may be included. Even in such a case, by generating a new message, it is possible to post or display a message with high information value.

In addition, the user can post a message to the messaging service based on traffic-related keywords such as "traffic jam", "accident", or "reverse run", and share the message with other users through posting to the messaging service. can. Then, as a new posted message, it is possible to generate a message regarding traffic jam, accident, or wrong-way driving. These keywords are considered to be keywords that are highly necessary for third parties, and users can easily post messages that are highly necessary for third parties.

In addition, for the user, multiple related messages are not displayed on the electronic device, and the user can collectively check the posted messages as one. For example, messages distributed in a messaging service may be collectively generated and posted as a posted message. This makes it easier for third parties to come into contact with posted messages containing necessary information by referring to the posted messages.

In addition, the user can include information identifying the user's account in the posted message and share the posted message with other users through posting to the messaging service. The information that identifies the user's account may be information handled by the messaging service, such as account ID, account name, and the like. In this way, even if the account that posted the message is different from the account of the person who posted the acquired message, the third party can post the message regardless of who the message is from.

In addition, the user can include the account of the person who posted the message as information identifying the account, and share the posted message with a third party through posting to the messaging service. Therefore, a third party can easily confirm who posted the message.
Also, the user's account may be the account of the user who logs into the management device.
In this way, even if the account of the user logging in to the management device is different from the account transmitted by the management device, the user can clearly indicate it to a third party. Also, a user who posts a message using the management device can know that the message was posted by the management device.

[1.4.10 Example of adding an image to a message]
In addition to the above-described embodiments, this embodiment posts images. That is, the message control unit 109 attaches the image to the generated message. A message with an image can be posted by the message posting unit 105 posting the message generated by the message control unit 109 to the service. This embodiment is particularly effective when the message posting unit 105 posts a message generated by the message control unit 109 to a service.

For example, if a drive recorder is connected to the electronic device 10, the image to be posted may be acquired from the drive recorder. Also, if the electronic device 10 is provided with an imaging device, an image may be acquired from the imaging device. Also, if the electronic device 10 can be connected to another device, for example, a terminal device such as a user's smart phone, the image may be acquired from the terminal device. Alternatively, an image obtained by capturing the display screen of the display unit 120 of the electronic device 10 may be used. Alternatively, it may be an image representing map information (for example, a map including the current position) that can be acquired by the electronic device 10 .

Here, the screen displayed on the display unit 120 of the electronic device 10 may be a display screen for assisting the driving of the vehicle. For example, the display screen may include traffic regulations (speed restrictions, road sign content). Also, the display screen may include vehicle information (for example, vehicle information acquired by OBDII). The display screen may also include the location of the traffic enforcement and the content of the traffic enforcement. In addition, a combination of these pieces of information may be displayed on the display screen. For example, the display screen may include a map including the current position, information on traffic regulations, and vehicle information (for example, vehicle speed).

Further, the electronic device 10 may add information to the image described above. For example, one or a plurality of images may include information indicating the current position acquired by the electronic device 10 (for example, the name of a town including a city), a road name, the state of the vehicle 50, and the date and time.

Here, if there is a limit on the size of the image in the service, the size and resolution of the image may be converted so as to fit within the limit. For example, the image is converted so that the maximum horizontal size is 600 pixels, the vertical size is unlimited, the aspect ratio is 16:9, the extension is PNG, JPG, or GIF image format, and the file size is 5 MB or less.

In this way, the user can include in the message information about the captured image of the display screen for assisting the driving of the vehicle, and share the message with other users through posting to the messaging service. can be done. The device that displays the display screen for assisting the driving of the vehicle may be an information processing terminal carried by the user, such as a smartphone, but the display screen of an electronic device that provides a function exclusively for assisting the driving of the vehicle. should be

Electronic devices include, for example, a drive recorder that provides shooting and recording functions, a navigation device that provides navigation functions such as route guidance, and a detector that has a notification function that notifies that it has a predetermined proximity relationship with a speed control point ( For example, radar detectors, laser detectors, etc. may be used. A map is often displayed on a display screen for assisting driving of a vehicle. Therefore, for example, a display screen including a map may be captured as a display screen for assisting driving of a vehicle, and a message including an image including the map may be generated. It is preferable to capture the display screen including the location (eg address or road name) and generate a message including the image including the location. In this way, a third party can use the image included in the message to check a map of the area where an event that could impede the progress of the vehicle has occurred, and also the location from the image. Become. Execution of the capture may be instructed by manual input by the user, for example, it may be possible to perform a one-touch operation. Capturing may be performed without explicit user direction, for example, when certain events occur, or periodically. The image used for posting may be instructed by the user, or may be selected without such instruction.

Also, when posting an image, the standby screen of the electronic device 10 may be set to a post standby state in which "posting" is possible. For example, the electronic device 10 provides an environment in which a message containing an instant image can be posted without an activation phrase for voice recognition.

Note that when posting to a service, the message posting unit 105 may post the message under conditions within the constraints of the service. For example, if the use of API access keys for posting to a service is combined with the process of confirming 200 of messages to be obtained, the posting interval may be set to 10 minutes or more, and posting may be performed according to service restrictions. . Also, the message posting unit 105 may impose a restriction such that the same message (data) is not sent continuously.

Thus, according to this embodiment, a message including an image can be posted. In general, images are displayed on the screen (timeline) that displays service messages. Therefore, when other users view the shared message, they can create and post messages that include images that are more appealing to other users than text only.

In addition, when posting an image, information including the link destination of the image may be included in the message, but even if the information indicating this link destination is included, the number of characters must be included in the terms of service. good too. For example, the message may be created within 140 characters including the information indicating the link destination.

[1.4.11 Example of Converting and Outputting Acquired Messages in an Easy-to-understand Way]
In this embodiment, when the message output unit 107 outputs a message, it converts the acquired message itself into a message that is easy for the user to understand and outputs it.

That is, the control unit 100 generates and outputs a new message based on the newly obtained message information.

For example, since there is a possibility that the message cannot be used as it is, the message output unit 107 determines an event from the message and displays the message on the display unit 120 .

For example, the message output unit 107 displays "accident traffic information" if the message is related to "accident". In addition, if the message is related to "wind driving", the message output unit 107 displays the message "wind driving has been reported". In this way, the content in the sentence may be automatically analyzed and a converted message may be output. If the message part is quoted as it is, it may be included in the claim, so it is possible to change the expression and output it. In addition, if the message is displayed as it is, it contains various expressions, so it is possible to create and output a unique wording.

Also, related messages may be combined into one message. For example, messages relating to the same accident in the same area may be combined into one message. Also, if the messages are related to the message (for example, the message that is sent back), they may be grouped into one message.

These messages may be managed as collective messages. Summary messages can be displayed as one thread. A summary message may be, for example, a single related topic and summarizes messages about a single event (eg, an accident or a traffic jam).

It is also possible to prepare a correspondence list between the word list string and the array wording, and display the replaced message when the character string in the message matches.

Also, the replaced message may be posted to the service by the message posting unit 105 . At this time, the message to be posted may further include information on the account of the posting user (for example, account name and account ID).

For example, as shown in FIG. 12D, search words, elapsed time, addresses, road names, detailed information, accounts, hashtags, etc. are newly generated, and the message output unit 107 outputs the message to the display unit 120. may

At this time, the electronic device 10 may display the above-described message together with the existing enforcement information. For example, when the existing control information is displayed as a telop, the above-mentioned messages may be displayed continuously or alternately.

Also, since the municipality is known, the message output unit 107 may display only the contents of the same municipality, like the existing enforcement information.

Also, the message output unit 107 may not only simply display the message, but may combine it with different displays. For example, if the message output unit 107 contains information that can identify a location such as an address, latitude and longitude, road name, IC/JCT/SA/PA name, landmark name, etc., the message output unit 107 outputs a location on a map or a road. may blink, change color, or display a pin.

Also, the message output unit 107 may output together with the elapsed time. The elapsed time may display the time that has passed since the date and time when the message was posted. Also, the elapsed time may specify the occurrence time of the event of the message, and may be the elapsed time from the occurrence time. For example, if the message includes "15:10 accident occurred", "15:10" may be set as the time of occurrence.

Also, the message output unit 107 may change the display mode according to the elapsed time. For example, in addition to displaying "X minutes ago" and "X minutes past" from the time of occurrence or message posting time, the color of road blinking can be made lighter or the brightness can be changed to reduce the deterioration of information. may be expressed. Also, the displayed message time may be limited to a specific range. For example, messages within 10 hours from the time of occurrence or the time of posting may be displayed.

Also, if the content (case) of the message is a reference to something in the past, it does not have to be displayed. It may be determined whether the content of the message (incident) is at the time of occurrence of the incident or at the end of the incident. In this case, the message output unit 107 may determine both the content of the message and the posted date and time.

For example, if the message "The traffic jam at Temmabashi yesterday was terrible" was posted today, the message output unit 107 may display the message as it is if the message was posted today. In this case, the posted date and time may be clearly displayed, and a predetermined time period (for example, 10 hours) may be displayed.

Also, if the content (case) of the message is in the past, it may be excluded from the display targets. In this case, the message ``The traffic jam at Temmabashi yesterday was terrible'' is excluded from the display objects because it has the keyword ``yesterday''.

Also, related messages may be obtained from a single piece of information, and the date and time of occurrence of the incident may be specified. For example, in the case of the message "The traffic jam at Temmabashi was terrible", a new message is acquired from the service based on the keywords "Temmabashi" and "traffic traffic accident" included in the message. At this time, if the contents of the acquired message or the date and time of posting are in the past, the message may be excluded from the display targets.

Further, information such as different services, news sites, weather information, and traffic congestion information (VICS information) may be searched for to specify the date and time of occurrence of an incident based on a keyword.

Also, the message output unit 107 may analyze the content of the message and determine whether to display it. For example, if the expression of the message is "I couldn't get through" instead of "I can't get through", it may be excluded from the display targets.

Here, the message acquisition unit 106 acquires a related message from the search word using, for example, the API of the service. The message acquisition unit 106 stores the acquired message in the storage unit 190 in a predetermined format (for example, CSV format).

Next, think of phrases (keywords) that are likely to be caught in a search, and search for an appropriate message. Specifically, a keyword is stored in the storage unit 190 in advance, and a search is performed using the keyword. The message output unit 107 creates a display message from the message including the keyword.

A specific example will be described. For example, in the case of Twitter as a messaging service, created_at, user.location, user.name, user.name, user.screen_name, user.followers_count, text, etc. are output in CSV format from tweets.json of the extraction source. Then, the message output unit 107 extracts and analyzes the data corresponding to the "date and time", "twitter name", "account", "place of occurrence", and "tweet" from the output CSV file, and creates a message for display. . As a result, the electronic device 10 can handle data in the same manner as existing public enforcement information data, and can display data in the same manner.

Here, the message output unit 107 analyzes the message by the following method. First, as analysis of the address data, the message output unit 107 confirms prefectures (47 items) and municipalities (1718 items) from the message. Also, since there is a possibility that there is a town character, the message output unit 107 adopts it as the name of the city, ward, town, and village if the terminal symbol is "wait". Here, the address dictionary 1996 shown in FIG. 12(C) may be used.

The analysis of the road data determines if the message contains road names for the entire country. Here, the road dictionary 1998 shown in FIG. 12(C) may be used.

Frequently used character strings may be registered in advance as a dictionary. For example, the message output unit 107 may adopt a message in the case of "traffic congestion" if it includes a character string of "single accident, multiple accident, injury or death, collision accident, truck accident, motorcycle accident, etc.". Also, the word dictionary 1994 shown in FIG. 12C may be used.

Note that the message output unit 107 may analyze the message using, for example, the message control unit 109 of FIG. 12 and output the message in the form of FIG. 12(D).

Also, the message output unit 107 may display related information. For example, news information obtained from a news site, weather forecast information, and the like may be output together as a message.

According to this embodiment, it is possible to convert the acquired message into a message in a predetermined format and post it. As a result, when other users check the message in the service, they can easily obtain the information because the message is output in a fixed format.

Also, the user can receive a message including an address or road name instead of the acquired message. For example, each user of a messaging service posts messages with different content. The user can check the message posted to the messaging service in an easy-to-understand output rather than as it is. Here, the address may be a combination of the name of the municipality and the name of the town, but it is better to use the name of the prefecture and the name of the municipality. Also, the address may represent any region, such as an intersection name, facility name, or landmark name. Also, the address may be latitude/longitude information or information indicating an area or location, such as a map code. Also, the road names may be names such as National Highway X and Prefectural Road X, road names such as Meiji Dori and Yasukuni Dori, and expressway names such as Chuo Expressway, Tomei Expressway, and Metropolitan Expressway.

Also, the user can receive messages containing information about traffic. Here, for example, traffic information such as "congestion", "traffic congestion", "accident congestion", and "construction congestion", information related to congestion such as "construction", "accident", and "closure", It is preferable to include information on safe driving such as "dangerous driving", "policing", and "police car". Also, the traffic-related information may be content that affects traffic, and may include disaster-related information such as "heavy rain," "flooding," "fire," and "earthquake."

Also, the user can check how much time has passed since the message was posted. Therefore, the user can confirm when the message was posted and how long ago the message is, along with the message. For example, if the message indicates a traffic event, such as a traffic jam, the elapsed time may be displayed along with the event. In this way, the user can know that an event related to traffic has occurred, and also confirm when the event occurred and how much time has passed since the event was posted. can do.

Here, the time that has elapsed since the message was posted may be obtained from the difference between the date and time when the message was posted and the current time, if the date and time when the message was posted can be acquired. Also, for example, the elapsed time may be obtained from keywords indicating time in the message (for example, "yesterday", "last night", "today", and "a while ago"). In addition, the control unit analyzes the message, and, for example, outputs that it is past information for a past sentence (for example, when it is determined as a sentence in the past tense). The elapsed time may be, for example, a specific elapsed time such as X minutes ago or X hours ago. good. Also, it is preferable to change the output mode of the message according to the time that has passed since it was posted. For example, when displaying a message, it is preferable to change the output mode based on the elapsed time since the message included in the output message was posted. It is preferable to change the mode of display such as reducing the size.

[1.4.12 Example of Determining Reliability of Acquired Message]
This embodiment is an embodiment in which the control unit 100 determines whether or not the content of the message acquired by the message acquisition unit 106 is reliable. The control unit 100 may calculate the credibility of the message and the credibility of the account based on information that can be obtained from the message and information on the poster's account. Then, the control unit 100 may determine the reliability of the message and the reliability of the account from the calculated reliability.

For example, the messages acquired by the message acquisition unit 106 include false alarms and messages related to rumors. For such fake information, for example, the control unit 100 may refer to the account information of the poster who posted the message.

For example, if the posted account is a corporate account, the control unit 100 determines that the message is highly reliable. Also, if the account that posted is an influencer account (for example, an account (number of followers) associated with the account is 3000 or more), the message is determined to be reliable.

These highly reliable accounts may be listed and stored in the storage unit 190 . The control unit 100 determines that messages posted from these highly reliable accounts are influential information. The message output unit 107 displays a message if the account is highly reliable.

Also, the message output unit 107 may change the mode of output according to the reliability of the message. For example, the message output unit 107 may display a message in blue for a message with high reliability, and display a message in yellow for a message with low reliability. In addition, the message output unit 107 may change the density of the characters, change the size of the characters, or change the scroll speed according to the reliability of the message.

Also, if the account is an official account, the control unit 100 may determine that the account is highly reliable. In this case, the message output unit 107 may also output that it is an official account.

Also, when a message is posted from an account with relatively low account activity, the control unit 100 may determine that the message is highly reliable. For example, when information such as an accident can be suddenly acquired from a message of an account with relatively low activity, it may be determined as information with a higher angle than information of a person with high activity.

Also, the control unit 100 may determine that a message to which location information is added is highly reliable. Also, the control unit 100 may determine that a message to which a predetermined keyword is added is highly reliable. For example, the control unit 100 may determine that a message added with a signature indicating that it has been output by the electronic device 10 is highly reliable.

Thus, according to this embodiment, processing can be executed based on highly reliable messages. Since services contain various messages, they are not always reliable. However, according to the present embodiment, it is possible to determine the reliability based on the account and the reliability of the posted message, and limit the processing to those determined to be highly reliable.

Alternatively, the number of accounts associated with the account that posted the message (the number of followers) may be obtained and output. In addition, the follow count may be obtained and output as the number of accounts associated with the account that posted the message. The messaging service may be a social networking service such as Twitter. In this way, the user can receive the number of followers of the first account and the number of followers.

In addition, when a large number of accounts are associated with the account of the user who posted, the user can determine that the account is highly reliable. For example, when the messaging service is a social networking service such as Twitter, for example, if the number of followers of the account that posted the message is more than a predetermined number, the user is a message posted from a highly reliable account. can be determined. Further, for example, when the user can determine that the first account is an account of an influencer or the like, the user may determine that the message has been posted by an account with high reliability.

In this way, the user can receive the number of followers or followers of the account that posted the message along with the posted message. For example, a user can determine the credibility of a message or account based on the influence of the account that posted the message (eg, an influencer's account with a large number of followers, etc.). Further, it is preferable to have a function of judging the reliability of an account or a message posted by the account based on the number of followers or followers of the account and outputting the result. For example, if the number of followers is greater than the number of followers by a predetermined percentage or more, the account may be determined to be highly reliable.
In this way, the user can know whether the account that posted the message is an established corporate account or an official account authenticated by the messaging service. The user can determine that the corporate account method is more trustworthy than the personally owned account. In this way, by outputting that the account that posted the message is a company account or a preset company account, the user can determine that the message is highly reliable. For example, it is preferable to have a function that allows the user to set a corporate account in advance, so that the user who posted the message can know that the user has a corporate account. Here, a corporate account is preferably an account owned by a company for the purpose of promotion or public relations activities, and is officially operated by the company, or one or more employees operate under the name of the company. should be an account. In addition, the corporate account may be an account of a private company, but as an account of an organization, an account of an organization such as a national or local government office, an institution, a foundation corporation, a medical corporation, a school corporation, an NPO corporation, etc. should be an account.

For example, it is preferable to have a DB (Data Base), inside or outside the device, in which the user can register a specific account (for example, NEXCO) as a trustworthy account. Also, for example, by analyzing the profile of the account information, it is preferable to specify that it is a corporate account.

Also, if the messaging service is, for example, an authenticated official account (for example, an account with an official badge displayed on the account), a different output mode may be used. In this way, if the account of the poster is an official account and the user determines that the account is highly reliable, knowing the official account can be used to determine the reliability of the message.

In addition, the user can preferentially check messages with high reliability. For example, messages posted to messaging services contain a mixture of correct and incorrect information. Also, for example, messages posted to messaging services are mixed with messages containing only facts, comments of users who posted, and irrelevant messages. In this way, the messages posted on the messaging service include unreliable messages such as messages not related to traffic, messages contrary to the facts, and messages that are true but have passed since the event occurred. It may contain so-called noise messages such as content messages. By determining the reliability of messages, it is possible to suppress the output of messages that are noise or to give higher priority to messages that are not noise. In this way, the user can preferentially confirm messages other than noise that the user needs.

[1.4.13 Example of User Evaluation Based on Posted Message]
A present Example is an Example which evaluates a user (driver) from the posted message. The control unit 100 determines the mental cycle (psychological state) based on the number of messages posted by the user and the timing of the messages.

For example, the message posted by the message posting unit 105 is stored in the message information storage area 196 . Then, the control unit 100 analyzes the message, determines the possibility of a traffic accident or dangerous driving, and evaluates the driving. That is, since many of the messages posted in the present embodiment have traffic-related content, it is possible to determine a cycle in which traffic accidents and dangerous driving occur frequently. For example, quantitative changes may be revised in chronological order, and, for example, it may be determined that there is a risk X minutes after driving, or the risk may be determined for each road (for example, expressway, general road). Specifically, the control unit 100 extracts messages containing the word "frustration". If there are many such messages while driving on an expressway, a notification may be issued to call attention to driving on the expressway. This provides an opportunity for the user to prevent accidents.

Also, the control unit 100 may evaluate the user's activity pattern from the activity cycle based on the time when the message was posted. For example, if there are many messages from 6:00 to 21:00, the control unit 100 knows that the user is active during that time. Also, if there are many messages posted during the daytime, the control unit 100 may determine that it is the lunch break.

In this embodiment, the control unit 100 analyzes the message posted by the message posting unit 105, but may also analyze the message acquired by the message acquisition unit 106, for example. In this case, the message of the account of the account information stored in the electronic device 10 may be analyzed, or the analysis may be performed based on another person's account.

According to this embodiment, various evaluations such as the user's state of mind and whether the user is driving safely can be evaluated based on the message posted to the service. For example, a safe driving ranking or the like can be performed by setting a plurality of evaluation targets. The user can also easily analyze the driving tendency and the like from the posted content.

[1.4.14 Example of Performing Voice Recognition Together with Message Output]
This embodiment is an embodiment that combines voice recognition with message display. For example, when posting a message from the electronic device 10, any message can be input in addition to automatically creating a message. Also, when outputting a message to the electronic device 10, the message can be output not only as a display but also as a voice.

In this case, the message posting unit 105 posts a message input by the user from the software keyboard of the electronic device 10 or a message generated based on words selected from the selection list.

Furthermore, the message posting unit 105 may generate a message to be posted by voice recognition. For example, the control unit 100 may generate a message by recognizing words input as voice, converting them into character strings. Further, the control unit 100 may display the categories of "accident", "traffic jam", "dangerous driving", and "disaster" on the display unit 120, and select from a word list on the screen to create a message. At this time, the control unit 100 may select the category based on the voice input by the user. Further, if the message is recognized as "traffic jam at the intersection" at this time, the control unit 100 may select the category "traffic jam" from the keyword "traffic jam".

In addition, when a word that is not included in the word list described above and can be in a category is voice-inputted, the message posting unit 105 may recognize the voice-inputted word and select it as a new category.

Also, screen transitions and the like may be performed by voice operation. For example, when the message output unit 107 is outputting a message and the user inputs "next message" as voice input, output of the current message may be interrupted and the next message may be output.

Also, during or immediately after outputting a voice message, the user may input whether or not he or she wishes to be notified of the follow-up to the current message by voice input.

Further, the message output unit 107 may output the message by voice together with displaying the message (for example, display by telop). The user may be able to select whether to display the message or output the message by voice. Also, the message output unit 107 may switch between displaying the message and outputting the message by voice according to the content of the message.

Also, the message output unit 107 may output the post category as voice each time the message is output as voice.

Speech recognition may also be performed by other devices. For example, when the electronic device 10 can be connected to a smart phone or the like, voice is input by the smart phone and the voice is recognized. Then, the smartphone may transmit the result of voice recognition to the electronic device 10 .

As described above, according to the present embodiment, it is possible not only to display information on the electronic device 10 but also to perform voice output and voice recognition operation. In particular, when the electronic device 10 is an in-vehicle device and is used by a driver, the screens that can be operated are limited. Therefore, by using voice recognition, the driver, who is the user, can operate the device without letting go of the hand, which contributes to safe driving.

Also, the user can confirm the message by voice. Since the user can confirm the message by voice, the user can confirm the message without paying attention to the electronic device even while driving. Therefore, the user can safely confirm the message. Changing the output mode and output method described above may be done by changing the volume of the sound output from the sound unit, changing the tone of voice, or changing the speed at which the sound is output. Also, the method of outputting sound may be, for example, a method of outputting a warning sound or music.

[1.4.15 Example of outputting detailed messages and related messages]
A present Example is an Example in the method in which the message output part 107 displays a more detailed message and a related message.

For example, when the message output unit 107 outputs a message, it outputs a summarized message. For example, in the case of an accident message including "#Chuo Expressway" in the hash tag, the control unit 100 may collectively output a message such as "Chuo Expressway Accident X cases".

In this case, the control unit 100 also displays the hashtag “#Chuodo”. When the user selects a hash tag, the message output unit 107 may sequentially display the messages before grouping.

Further, when the message itself is selected, the control unit 100 may switch and display the message that is the source of the combined message.

Further, when the display area of the display unit 120 is limited (narrow), the control unit 100 may enable display on another device. For example, the control unit 100 may display a two-dimensional code including information for guiding to a screen to be collectively displayed. The user may display the details of the message by reading this two-dimensional code on a terminal device such as a smartphone.

Also, the two-dimensional code may include a link for displaying a list of summary messages. A summarized message is, for example, a message in which reply messages (replies) to a predetermined message are summarized. The two-dimensional code includes a URL that can display this summary message in a list.

By reading this two-dimensional code in a terminal device such as a smart phone, a list of summary messages can be displayed on the terminal device.

Also, when a new message is added to the summary message, the electronic device 10 may display that the message has been added. For example, if the message acquired by the message acquisition unit 106 is one of summary tweets, the display unit 120 may display that a new message has been added. Also, at this time, a two-dimensional code may be displayed together.

According to this embodiment, it is possible to summarize related messages as a summary message. A messaging service can put messages together, for example, by using a reply function. In this embodiment, it is possible to collect related messages by utilizing the reply function.

In addition, for the user, multiple related messages are not displayed on the electronic device, and the user can collectively check the posted messages as one. For example, messages distributed in a messaging service may be collectively generated and posted as a posted message. This makes it easier for third parties to come into contact with posted messages containing necessary information by referring to the posted messages.

Also, if the user wants to display a related message, the related message can be viewed by selecting the link. When a link is selected, a list of related messages should be displayed. Also, it is good to display related messages in threads. In this way, the user can view the message in a highly viewable state.

Also, the user can check the related message associated with the link by reading the two-dimensional code on a terminal device such as a smartphone. For example, it is preferable to jump to a site displaying a list of related messages from a link included in the two-dimensional code and display it on the terminal device. Note that an encoded image obtained by encoding information other than the two-dimensional code may be used.

Also, the user can confirm the content of the acquired message by referring to the posted message. At this time, all contents included in the acquired message may be included, but only part of the contents may be included. Since the acquired message is included in the posted message, the user can easily confirm the content of the message posted by the posted user.

Also, the user can check related messages in an aggregated state. A related message may be, for example, a messaging service in which one message is related to another message. For example, assuming that Twitter, which is a social networking service, is used as a messaging service, in this case, a reply (reply), a repost (retweet), or the like may be used. By aggregating related messages, users don't have to check similar messages over and over again. For example, in the case of a reposted message, a similar message is output for the reposted message. Therefore, for example, by outputting the reposted message only once, the user can confirm only one of the related messages.

In addition, the collective output here means that a plurality of messages may be collectively output. The collective output may be, for example, displaying only one representative message. As one representative message, the first posted message may be selected, but a new message may be generated and output.

In addition, the user can confirm messages that have been replied to one message in an aggregated state. For example, for a message that is a reply (for example, reply) to a certain message, only the reply source message may be output, but it is preferable not to display the reply (for example, reply) message. As a method of using the messaging service, for example, the reply message often contains more important information than the reply message. Therefore, it is preferable to output the message of the reply source. Also, even if messages are returned to a single message in the form of a thread, it is preferable to aggregate them as related messages.

In addition, the user can collectively receive the reposted messages. For example, as a repost message (for example, retweet) for one message, only the message of the repost source (for example, retweet source) should be output. In this case, the reposted message (for example, retweet) can be prevented from being displayed. . In general, a reposted (for example, retweeted) message has almost the same content as the reposted (for example, retweeted) message, so it is preferable to display the reposted (for example, retweeted) message.

Also, the user can receive some or all of the messages that are aggregated. For example, it is preferable to output (for example, as it is) all of the aggregated messages among the aggregated messages. For example, when messages are aggregated, the user can confirm what kind of messages have been aggregated by outputting the original message as it is or by outputting a part of the message.

In addition, the user can also check the number of messages in which the messages are aggregated. For example, the number of times the message has been reposted (eg, retweeted) or the number of replies (eg, the number of replies) may be output together with the message. By confirming the message and the number of aggregated messages, the user can recognize that the message has a greater response. For example, the user can recognize that a message that receives a large response is important or highly reliable.

Also, the user can recognize how many times the message has been reposted according to the output mode of the message. For example, when the number of times the message is reposted (the number of replies) is large, the control unit may change the font type or size of the message, or change the color of the characters. Also, it is preferable to gradually change the output mode of the message according to the number of times the message is reposted (the number of replies). In this way, the user can check how often the message has been reposted. For example, as the number of reposts increases, the color of the text may change from white to red. In this case, the user may perceive that the closer the color of the text is to red, the greater the number of reposts (the greater the number of replies). can recognize.

Also, the user can recognize how many times the message has been reposted based on the size of the message. For example, the number of reposts may be displayed together with the message, and whether the number of reposts is large or small may be displayed according to the size of the message or the size of the display area. In addition, the user can recognize a message that has been reposted a large number of times as an important message because it is a message that has spread to many people. Therefore, the more important a message is reposted, the larger the message is displayed, so that the user can intuitively grasp the importance of the message.

Also, the user can use the two-dimensional code to check the collected messages. For example, the user causes another terminal device (smartphone, tablet, etc.) to read the two-dimensional code. The terminal device displays the aggregated message based on the information (for example, URL, etc.) indicated by the two-dimensional code. Here, the two-dimensional code preferably contains, for example, a URL for displaying a list of aggregated messages. In addition, the aggregated messages may be displayed one by one, for example, but it is preferable to display them in a thread. Note that an encoded image obtained by encoding information other than the two-dimensional code may be used.

[1.4.16 Example of Switching Message Output Method]
A present Example is an Example which switches the output method when outputting a message.

The message output unit 107 switches the output method according to the hash tag included in the message. The message to be acquired may include a hash tag of the target type for distinguishing the incident and the name of the place where the incident is occurring in the hash tag. Here, the place names and the like may be those included only in hashtags.

For example, messages announcing current road conditions often use hashtags to indicate the location.

Message A: "# Accident congestion # Hanshin Expressway # Moriguchi Line"
Message B: "#Osaka #Rinkai #Accident traffic #Prefectural road No. 29 facing south
#Near Takaishi Bridge
Message C: "#Matsumoto City #Accident Traffic #What a day"
Message D: "#Aqua Line #Accident Congestion"
Message E: "#Himeji Bypass #Accident Congestion #People Who Forgot It's a Holiday"
#holiday saturday
With respect to such messages, the control unit 100 executes search with hash tag and search without hash tag for the same keyword. Information based on messages with hash tags and information based on messages without hash tags may be output in different notification modes.

Also, the range of posting dates and times to which the message output unit 107 outputs a message (notification target) may differ for each type (for example, each hashtag). The range of this post governor may be set for each type. For example, the range of messages to be acquired may be set to 1 day for "# traffic congestion" and 7 days for "# crackdown".

In addition, the message output unit 107 may output an account (a message of a follower) whose message contributor is related to the user of the electronic device 10 in a different manner. For example, the voice quality (TTS) to be read out may be changed, the speed of reading out may be changed, and the volume may be changed.

Further, when the light emitting unit 180 is used for notification, the message output unit 107 may change the color of the LED to be issued or the light emission pattern.

As a result, even when the user is driving, it is possible to easily determine whether the message is simply a message about an accident or the like, or whether it is a message from someone who is following. Also, the user can easily pay attention to information such as an accident.

In addition, the message output unit 107 may output an action (for example, a reply (reply tweet), a repost (retweet), or an evaluation (like)) to one's own message in a manner different from other actions. good.

In addition, the message output unit 107 may further play music (play a predetermined audio file) in the case of an action for its own message. In this case, the message output unit 107 does not need to play music when outputting a mere message.

According to this embodiment, necessary notifications can be made according to the tags included in the message and actions. Many messages are posted on messaging services, and it is highly likely that you will miss them if you simply display them. Therefore, for example, by giving a different notice for an action addressed to oneself, it is possible to prevent an action addressed to oneself from being overlooked. In addition, by utilizing hashtags in messaging services, information can be obtained quickly from services. In particular, hashtags are highly likely to contain related messages, so effective use of hashtags enables effective notification.

According to this embodiment, a user may receive information whether the user's account that posted the message is associated with his or her own account. The messaging service may be a social networking service such as Twitter. In this way, the user can know information such as whether the user who posted the message is being followed or whether the user is following the user. As the information on whether or not the account is associated, information that can identify the account of a friend or the account of an acquaintance may be used. In this way, if the user's second account is associated with the first account, the user knows that the post is not from an unrelated account. Therefore, users can follow highly reliable accounts. At that time, if the account that posted the second message follows the account, the user can determine that the message has been posted from a highly reliable account.

Also, for example, it is preferable to output the voice from the voice output unit as the output destination of the message, and it is preferable to change the output mode such as the volume, tone, and output speed of the voice. This makes it easier for the user to grasp the account information. Specifically, for example, in the case of an account that is not related to the user, the message may be output in a male voice, and in the case of an account related to the user, the message may be output in a female voice.

Also, in the posted message, if the person who posted the message is driving, that fact may be output. When receiving the message, the user can confirm that the message was posted while driving. For example, this message may be a traffic jam message. When judging that the message sent by the actual driver is highly reliable, the user can confirm the highly reliable message among the displayed messages regarding traffic congestion.

Also, the user can recognize the number of acquired messages by the message output method. For example, when the acquired message is displayed by scrolling, it is preferable to switch the speed of scrolling display. Further, for example, when displaying the obtained messages in a predetermined area, it is preferable to change the font size or the size of the display area according to the number of messages. Also, when outputting the acquired messages by voice, it is preferable to change the voice output speed according to the number of acquired messages. In this way, since the message output method changes according to the number of messages, the user can also recognize whether the number of acquired messages is large or small when viewing or listening to the acquired messages. .

Also, the user can recognize how many times the message has been reposted by the light emission pattern of the light emitting unit. This means that when the device is provided with a light emitting unit, the light emitting method of the light emitting unit changes according to the number of times of reposting. For example, as a light emission method, it is preferable to change the number of flashes, change the luminance, or change the color. For example, in the case of a message that has been reposted many times, it is preferable to increase the frequency of light emission. By doing so, the user can be alerted. In addition, the user can recognize the approximate number of reposts of the message from the light emission pattern of the light emitting unit. For example, when displaying a message with a large number of reposts among displayed messages, it is preferable to output a light emission pattern indicating that the number of reposts is large. In this way, the user can recognize whether or not the message has been reposted many times without bothering to read the message.

[1.4.17 Example when the acquired message is a reposted message]
This embodiment is an embodiment in which at least a part of the original message is used as information on an accident or the like and is output as it is, and a repost is not output as it is.

When the acquired message information is a reposted message, the message output unit 107 may output the message as it is or may output only a part of the message. In addition, when the obtained message includes a quoted message from another user, the message output unit 107 may output the message without quoting the quoted part, omit part of the message, or output the message according to a predetermined wording. A message may be output instead.

Also, the message output unit 107 may switch the message output method according to the type of repost (retweet). For example, when a message such as an accident is reposted, the control unit 100 may output the message together with the number of reposts counted by a predetermined method. In addition, the control unit 100 may perform totalization at regular time intervals.

For example, the message output unit 107
"There is a message saying 'It looks like an accident at Yahagi Bridge. You're late because of heavy traffic.'"
It is also possible to output "The earlier message 'Accident at Yahagi Bridge' has been reposted three times in the last five minutes."

Furthermore, after another 5 minutes, the message output unit 107
"The earlier message 'Accident at Yahagi Bridge' has been reposted 30 times in the last 10 minutes."
and periodically output a message.

Also, when messages containing the same keyword (for example, a proper noun such as a place name) are within a predetermined time range, the message may be output (announced) as a related message.

For example, after the notification described above, the message output unit 107
12 minutes ago, there was a tweet related to "Accident at Yahagi Bridge". "An ambulance came to Yahagi Bridge, but I'm in trouble because I can't get to the site."
and output a message.

In addition, when there are a predetermined number or more of new messages containing the same keyword (for example, a proper noun such as a place name) within a predetermined time range, the message output unit 107 may output (notify) the number as related tweets. good.

At this time, the user may select whether to repost the message or output the message that was the source of the quote.

For example, when the user instructs to output a message by voice, the message output unit 107 may determine that the user has instructed to read aloud, and may output the message by voice.

For example, the control unit 100 says, "There are 12 related messages of 'accident at Yahagi Bridge' five minutes ago. Would you like to read? ” is output from the voice output unit 130 . When the user inputs "read aloud" by voice operation or touch operation, the voice output unit reads out the related message.

In addition, the message output unit 107 may display the temporal transition of the number of reposted messages, related messages, etc. in a graph or the like for each type and total. The message output unit 107 may display this graph when reading the message. Further, when displaying a message, the message output unit 107 may display a graph or the like together with the message to be displayed.

In addition, the message output unit 107 may output (notify) a reposted message or a related message more conspicuously as the number of related messages increases.

For example, the message output unit 107 may enlarge the character size of the message to be displayed, or may increase the frequency of light emission of the light emitting unit 180 . Also, the message output unit 107 changes the color of the LED of the light emitting unit 180 from blue→yellow→red, or changes the sound output from the voice output unit 130 from “pop” to “pyrrilro pyrrilro”. good too.

Furthermore, if the posted message or the place where the incident contained in the message occurred is known, it is preferable to make the notice conspicuous by taking into consideration the state of proximity to the place in addition to the above-described control of the notice.

Thus, according to this embodiment, if the obtained messages are replies (reposts), the messages may be output collectively. In particular, in the service, a message with many reposts (retweets) may be determined to be of high importance. Also, by outputting the message including the number of times of reposting, other users may recognize how important the message is.

Also, the user can hide the content of the reposted message from the posted message. Generally, the reposted message contains the same content as the message that was the subject of the repost. Therefore, it is possible to prevent the same content from being displayed by including a repost message. As a messaging service, for example, Twitter as a social networking system may be used. In Twitter, a reposted message is a retweet.

In addition, when there is a message to be reposted among the acquired messages, the user can recognize how much the message has been spread by checking the number of times the message has been reposted. In general, the higher the number of reposts, the more credible the message can be rated.

In addition, the transition of the number of times of reposting is displayed in a graph, so that the user can easily visually grasp what kind of diffusion transition occurred.

Also, the user can opt out of receiving reposted messages, thereby reducing the number of messages with duplicated content. For example, it is preferable to provide a function of acquiring messages other than reposted messages. By doing so, it is possible to prevent a situation in which the user cannot confirm messages other than reposted messages. For example, if a given posted message is reposted multiple times, the reposted message is not output, so the user can be prevented from receiving messages with duplicate content. Also, when a message is reposted by various users, the same message is repeatedly re-output. The user can avoid having to check the same reposted message repeatedly.

The messaging service may be, for example, Twitter, which is a social network service, and the repost message may be a retweet message. Also, a message containing a specific character string such as "RT" may be used as a retweet message. Also, for example, the repost message may include a quoted retweet. For example, it is preferable to determine that a quoted retweet is a message that includes another message other than the message following "RT" or that includes "QT". Also, for example, it is preferable that the message part following "RT" is not output as a message for the part not output as the message.

[1.4.18 Example of outputting a newly output message]
This embodiment is an embodiment for outputting new messages excluding messages that have been output until the previous time.

For example, the control unit 100 outputs, at regular time intervals (for example, once a day), a new message obtained from the service with the keyword registered by the user, excluding the previously notified search results. good too.

Further, the control unit 100 may output a newly acquired message from the previous time to the current time, for example, when the power of the electronic device 10 is turned on. For example, when the power is turned on, the control unit 100 may output (read out) a new message as voice.

Also, the control unit 100 may output a makurakotoba before outputting the message. For example, it is possible to output first, "Today's new message with the registered keyword 'construction traffic jam' will be read aloud."

According to this embodiment, it is possible to notify at regular intervals based on a predetermined keyword. Therefore, when the vehicle is used for the first time, traffic-related information or general news information may be distributed.

[1.4.19 Example of processing for account]
This embodiment is an embodiment in which, when outputting a message, an additional message is output according to the poster (account) of the message to be output, or processing is performed for the account.

For example, if the account that posted the message to be output is not associated with the account of the user of the electronic device 10 (for example, if the account of the user is not followed), the text of the profile of the account is output as voice. may

In addition, while the message output unit 107 is outputting the message or after outputting the message, the control unit 100 inputs an instruction to associate (follow) the account that posted the message with the user's account, or automatically associates the account. You may decide to do (follow).

As a result, for example, when the acquired message is output by voice in the electronic device 10, the control unit 100 determines that the account that posted the message is followed by the account of the user using the electronic device 10 ( related). Then, when determining that the user's account is not being followed, the control unit 100 notifies the user that the account is not being followed during or after outputting the message by voice, or notifies the user that the account is not being followed. You may output a profile by voice. In addition, the control unit 100 may confirm whether to follow the unfollowed user or automatically follow the user. Alternatively, for example, the control unit 100 may add the unfollowed user to the list.

Also, the method of association (following) may be changed by user settings. For example, in normal follow-up, it is common to select people whose hobbies you want to receive messages from in the future. So once you follow someone, you are less likely to unfollow them. On the other hand, there is a period when people are interested in news information such as accidents.

Therefore, the control unit 100 may extract related accounts and temporarily register them in a group (for example, follow group or list).

That is, in addition to the linking (following) function provided by the service, the storage unit 190 may store information related to related accounts.

According to this embodiment, the user can receive information about the first account that posted the message. The information on the first account may be information handled by the messaging service, for example, information that can identify the account such as the account name and account ID, an image associated with the account, detailed information on the account, and information on the account. At least one of profile information is recommended. In this way, the user can keep track of who posted the message or information about who owns the account.

Also, the user can receive information about the account that posted the message if the account that posted the message is not associated with the user's account. The user's account and the account that posted the message are not associated, for example, when they are not in a friend relationship or in a follower relationship in the social network service. Since the account that posted the message is not associated with it, the user can get information about that account. In this way, the user can confirm what kind of user posted the message. Here, the information about the account may be, for example, the place of residence, birthday, hobbies, etc. of the user who posted the message.

In addition, the user can receive one or a plurality of information on the profile, information on the number of followers, information on the number of followers, etc. as information on the account that posted the message, and grasp information on the first account.

For example, the profile of the user who posted the message (for example, area of residence, hobbies, favorite things) may be output together. Also, information on the number of followers and information on the number of followers may be output individually, or a plurality of pieces of information may be output together. In this way, the user can obtain information about the account that posted the message.

Also, the user can receive information to associate or recommend to associate the first account that posted the message if the account of the user who posted the message is not associated. The user can determine whether or not to associate based on this information. For example, when a user sees a message and determines that the user is posting a useful message, the user can easily follow the user. For example, Twitter or the like may be used as the social network service, and if the user does not follow the second account, the user may be recommended to follow the second account. Also, for example, if the user is not following the second account, it may be automatically followed. In addition, it is preferable to have a function of preferentially obtaining messages posted by accounts followed by the user and changing the output mode.

In this way, the user can confirm that the account that posted the message is an account that meets specific conditions. Here, as a specific condition, for example, if the user has entered a predetermined keyword, the keyword may be included in the profile information of the account that posted the message. As a specific condition, for example, it is preferable that, as an attribute of an account, an attribute value (specifically, the number of followers/the number of followers, etc.) of a related account is equal to or greater than a predetermined threshold. Also, as a specific condition, for example, the account may be an account certified by the messaging service. By knowing that a specific condition has been met, the user can determine, for example, whether to associate the account (eg, follow). In addition, the user can determine whether or not the reliability of the message is high by knowing that the specific condition is met.

[1.4.20 Example when having multiple account information]
This embodiment is an embodiment in which there are multiple user accounts using the electronic device 10 . The account information storage area 192 can store one or more pieces of account information about a user.

For example, when the message output unit 107 acquires a message from a service, the message output unit 107 may output the message differently according to the acquired account. For example, when the message output unit 107 displays a message, the message display color (character color, background color), message font, telop display speed, etc. may be switched in association with the account. Also, when the message output unit 107 outputs the message by voice, the tone of the voice output may be changed. This allows the user to easily determine from which account the message was obtained.

Further, when the message acquisition unit 106 acquires messages from multiple accounts, duplicate messages may not be output. Also, the message output unit 107 does not have to output the same message even if the account is different. Also, if the character strings included in the messages are the same or substantially the same even if the accounts are different, the message output unit 107 does not need to output the messages.

For example, different accounts may follow the same user's account. If the electronic device 10 notifies each of them, the user feels annoyed. Therefore, only one duplicate message may be output, and the other messages may not be output.

Also, the message posting unit 105 may post from at least one predetermined account.

In this way, the user can have the information for logging into the messaging service stored on the electronic device itself. For example, since the login information is stored in the electronic device that the user owns, the user can use the messaging service without worrying about leakage of the login information. Also, for example, the user can reduce the trouble of inputting login information when using a messaging service.

Also, the user can store multiple pieces of login information in the electronic device and switch the login information to receive messages from the messaging service. In this way, since a plurality of login information can be stored, a user can, for example, use a private account that is normally used as login information and an account that is used for the purpose of collecting traffic information with an electronic device. can be used to store two Also, the control unit may use a plurality of stored login information together, but preferably has a function of switching between them. For example, the control unit outputs only the message acquired by logging in based on the first login information when the user switches, or outputs only the message acquired by logging in based on the second login information. It is good to Moreover, when using both, the user should log in based on the first login information and the second login information, and output the messages obtained from both.

Also, even if messages are obtained based on a plurality of different accounts, the user can receive only one duplicate message among the messages obtained from each account. For example, when a user outputs messages obtained from different accounts together, if each user's account follows the same other user's account, duplicate messages may be received. Therefore, the control unit should display only one message instead of outputting each duplicate message. By doing so, the user can avoid receiving the same message repeatedly. Also, since duplicate messages are not output, the control unit may, for example, output other messages accordingly. Also, the control unit preferably changes the display mode of the message when, for example, overlapping messages are combined into one.

[1.4.21 Example of Posting According to Posting Conditions of Service]
This embodiment is an embodiment in which the message posting unit 105 posts a message to a service according to posted information on the service.

For example, a contract is shown when using a service from a service provider. The message posting unit 105 posts messages according to the rules. For example, if the service has a rule that the posting interval is 10 minutes, the message posting unit 105 posts the message after 10 minutes.

Also, the message acquisition unit 106 may acquire the message according to the service agreement. For example, in the case of 10 times in 10 minutes, obtaining messages at shorter intervals than that number should be avoided, and messages should be obtained within the number of times.

According to this embodiment, even if the service side imposes restrictions on the use of the system, it is possible to operate according to the restrictions.

[1.4.22 Example of changing the display mode of the message according to the size of the display part]
This embodiment is an embodiment in which the display mode of the message changes according to the size of the display unit.

When the message output unit 107 outputs the message to the display unit or the display device, the display mode of the message may be changed according to the size and resolution of the display unit.

For example, the message output unit 107 may scroll the message horizontally in the case of the display unit 120 having a wider horizontal resolution or a display device. In addition, the message output unit 107 may scroll the message vertically in the case of the display unit 120 having a wider vertical resolution or a display device.

Also, the arrangement of the messages may be changed according to the resolution of the display unit 120 or the display device. The message output unit 107 may change the direction in which messages are displayed, the arrangement of messages, and the direction of scrolling according to the type of display device. For example, when displaying on the display unit 120 of the electronic device 10, the size is limited. Alternatively, if the size of the display unit of the car navigation device is large, the scrolling direction of the message may be changed.

[1.4.23 Example of cooperating with another device]
A present Example is an Example which evaluates the reliability of a message from the driving|running|working history etc. which were transmitted from other apparatuses, or estimates a place.

For example, the electronic device 10 transmits travel history information indicating a travel history as one piece of vehicle information. As a transmission destination, for example, the travel history information is transmitted to a server device capable of managing it. Also, the electronic device 10 may transmit to another electronic device 10 as necessary.

Control unit 100 receives travel history information from another device via communication unit 146 . The travel history information may be, for example, a GPS log or the like. In addition, the travel history information includes date and time, travel speed of the vehicle 50, latitude and longitude information, travel distance, address, municipality name, road name, etc., as required.

In addition, the electronic device 10 transmits travel history information to the server device as necessary. The electronic device 10 may transmit to the server device periodically (for example, every hour) or may transmit when the power is turned on. Further, the electronic device 10 may transmit at the timing when the size stored in the travel history information becomes a predetermined size. Further, the electronic device 10 may transmit, for example, when an abnormality of the vehicle 50 is detected or when an accident is detected.

The control unit 100 may determine the reliability of the message from the travel history information. For example, in response to the message "A traffic jam is occurring at Nagoya Station", travel history information including the area around Nagoya Station is acquired. Here, it is determined whether or not the traffic is really congested from the travel history information including the area around Nagoya Station.

Further, the control unit 100 may detect congestion or an accident from the travel history information. In this case, the message generating unit 104 may generate a message saying "it seems that there is a traffic jam".

In addition, the control unit 100 may automatically send a message asking for details to the user for information such as information on accidents and traffic jams that particularly requires immediacy. The message sent to the user may be a direct message (for example, a direct message) that can be communicated one-to-one.

Then, the electronic device 10 may perform processing according to the content of the returned message. For example, the user may perform the process of adding more words, or the process of taking the word to increase reliability.

Also, for direct messages, a template may be stored in advance, and the message may be posted as a reply tweet to the original message using the template as the text.

[1.4.24 Example for Implementing Questionnaire Function]
A present Example is an Example using the questionnaire function provided in the service.

For example, the message generator 104 generates a message using a questionnaire function provided in the service. A message posting unit 105 posts a message using the questionnaire function to the service.

Thus, for example, it is possible to tally whether or not the collected information is correct using the questionnaire function of the message service. The questionnaire function of the service may use, for example, the questionnaire function of Twitter.

For example, FIG. 13 is an example showing a display screen W150 displaying a message including a questionnaire. The display screen W150 displays a message display region R150, a quoted message R152 to be surveyed, and a survey response region R154. Also, as functions provided by the service, the number of votes and the remaining time of the questionnaire are displayed.

By using the questionnaire in this way, the user can evaluate whether or not the posted message was appropriate.

Also, the questionnaire results may be graphed in real time and output. For example, the message acquisition unit 106 periodically acquires the number of poll votes. A line graph, a bar graph, a circle graph, or the like is generated for the number of votes in the questionnaire, and displayed on the display unit 120 . Also, the control unit 100 may post a message including the graphed result to the service again.

Further, the questionnaire results may be aggregated by an external server device and distributed to the electronic device 10 . For example, the external server device acquires the number of questionnaire responses from the service every predetermined time. Then, the external server device may aggregate the results of the questionnaire based on the number of responses to the questionnaire. Electronic device 10 may display the results on display unit 120 upon receiving the results of the questionnaire from the external server device.

In addition, the external server device may transmit summarized information (for example, aggregated results of a questionnaire) to the electronic device 10 according to the status of reposting of the questionnaire message (the number of retweets).

Alternatively, the external server device may conduct a questionnaire as a service instead of the reposting status, and then transmit the aggregated results to the electronic device 10 based on the questionnaire status. For example, the external server device may transmit the aggregate results of the questionnaire to the electronic device 10 when the number of questionnaire responses reaches a target value or when a certain number of responses are collected.

Further, the external server device or the electronic device 10 may change the questionnaire time according to the number of collected questionnaires. For example, if the number of responses is insufficient, the message including the questionnaire may be posted to the service again.

In addition, the external server device or the electronic device 10 may delete the tweets in the questionnaire when the number of responses for tallying the questionnaire has been collected (when the set number of responses has been reached).

In this case, the external server device or electronic device 10 may send a message to the service based on the results of the questionnaire. For example, the external server device or electronic device 10 may post a screenshot image showing the results of a questionnaire to the service. Also, the external server device or the electronic device 10 may post numerical values indicating the results of the questionnaire to the service.

Note that the questionnaire may be implemented by individual messages (for example, direct messages) to each user instead of public messages.

In this way, the user can take a questionnaire for third parties through the in-vehicle device. As a messaging service, for example, Twitter as a social networking system may be used. Since Twitter has a questionnaire function, it is good to use it. The questionnaire function may be realized by directly using a message or the like. By executing a questionnaire function, for example, a questionnaire may be conducted to confirm whether or not a message posted by a user is correct with a third party, and the message may be evaluated by the questionnaire. The contents of the questionnaire by the questionnaire function may be manually set by the user, but may be determined without such setting. For example, the content of the questionnaire may be determined according to the state of the vehicle. For example, when it is determined that traffic congestion is occurring, a questionnaire function is executed to determine whether it is better to select a route with traffic congestion or a route that avoids traffic congestion. It is advisable to confirm this with a questionnaire.

[1.4.25 Example using trend]
A present Example is an Example using the trend in a service. Trends refer to phrases contained in many messages in the service. If there is a word or phrase included in the trend ranking that should be output as a message, the control unit 100 outputs a message based on the word or phrase included in the trend ranking. Here, the message output unit 107 may distinguish between the message acquired based on the words included in the trend ranking and other messages and display them. For example, distinguishing information may be added and displayed, or the color or font of the message may be changed. Also, the message output unit 107 may change the voice tone when outputting the message by voice.

In this way, the user can receive messages containing trending words in the messaging service. For example, the message to be obtained may be obtained by performing an AND search for words that can be extracted as a trend together with traffic-related information, or by performing an OR search. For example, only trending messages may be acquired from traffic information, or messages including trending words may be acquired together with traffic information. Also, when displaying a message including a trending word, it is preferable to change the output mode of the message. Also, the trending words may be included in a part of the message, or may be included as a tag.

[1.4.26 Example of searching for related places]
This embodiment is an embodiment of displaying a message with additional information added from a character string included in the message or posting the message to a service.

For example, the control unit 100 determines an accident or traffic jam message from the acquired message. Then, the control unit 100 acquires the latitude and longitude information of the location included in the message.

The control unit 100 acquires surrounding area information from the acquired latitude and longitude information. Then, a word or phrase that is trending in the region may be obtained and added to the message. Further, the control unit 100 may acquire surrounding messages and area information from the latitude and longitude information, and improve the message system. For example, the control unit 100 includes latitude and longitude information in a message including "traffic jam". At this time, the message acquisition unit 106 acquires messages posted around the latitude/longitude information. Then, if the control unit 100 can acquire a message about "traffic jam" from other messages posted around the latitude/longitude information, the control unit 100 can determine that the reliability of the first message is high.

Also, the control unit 100 may search for related information from the service. For example, from the obtained latitude and longitude information, a message including nearby facilities and events is obtained, or information about a store is obtained. For example, if the user is stuck in a "traffic jam," information can be provided that allows the user to stop by a store or enjoy an event to avoid the traffic jam.

According to this embodiment, when a message is acquired, surrounding area information is acquired based on the posted content of the message or location information included in the message. Then, it is possible to extract a message containing information about the surrounding area. This allows the reliability of a message to be evaluated based on other messages. Also, the user can be further provided with additional information when the user is stuck in traffic.

[1.4.27 Example using RSS]
The electronic device 10 has a function of registering an RSS feed on the net and displaying information delivered by the RSS feed as a telop.

The services described above may be RSS feeds. That is, the message acquisition unit 106 may acquire messages based on RSS feeds.

This RSS feed may be registered by the electronic device 10 or may be registered by another device. For example, an RSS feed may be registered using a dedicated application, or information registered on a website may be acquired. RSS feeds may also be registered using the user's browser. For example, the registered information may be obtained by pressing the Follow button or the like of the browser.

For example, an external server device, the electronic device 10, or another device equipped with a browser acquires the address information of the RSS registered in the user's browser. When the information (RSS feed) of the address is updated, the information may be summarized and distributed to the electronic device 10 or displayed.

Alternatively, it is possible to determine (by filtering, etc.) whether or not the RSS contains traffic-related information, and aggregate the information containing traffic-related information and distribute it to the electronic device 10 .

[1.4.28 Example of setting the message output destination to a service]
This embodiment is an embodiment in which another device (server device) or the like is used as a message output destination.

For example, the message output unit 107 described above outputs a message generated by the control unit 100 (for example, the message control unit 109). The message output unit 107 has output destinations such as message display by the display unit 120, audio output by the audio output unit 130, LED lighting by the light emitting unit 180, and the like. The message output unit 107 may output to other devices and services other than the output destinations described above.

For example, the message output unit 107 may display a message created based on the acquired message on the display unit 120 and output the message to a service. The message output unit 107 outputting a message to a service means posting the message to the service via the message posting unit 105, for example.

Here, the message output unit 107 may output (post) the message only to the service without outputting the message in the electronic device 10, or may output (post) the message to the service in conjunction with outputting the message in the electronic device 10. You may output (post) a message. Also, the message output unit 107 may switch the output destination according to the importance or reliability of the message. For example, it is assumed that the message control unit 109 creates a summarized message based on the messages acquired by the message acquisition unit 106 . At this time, if the original message is highly evaluated or the number of reposts is large, the control unit 100 may determine that the message is important.

If the control unit 100 (message output unit 107, message posting unit 105) determines that the message is of high importance, it posts the generated message to the service. At this time, the message posting unit 105 may post the message in the form of replying to the original message, or may post the message in the form of quoting (quoted retweet).

[1.4.29 Example using bookmark function]
A present Example is an Example using the bookmark function which a service has. If a "bookmark" is recognized by voice recognition while a message is being read aloud in the vehicle by the electronic device 10 or the like or a Twitter client application for a smartphone, the message is saved as a bookmark.

The user may be allowed to select whether this storage location is a Twitter bookmark (on a Twitter server) or only inside the device such as the electronic device 10 .

Here, the function selected by the user may be set in advance on the setting screen and determined according to the contents of the setting. In addition, the storage destination may be designated by changing the words for speech recognition.

This is because information such as traffic jams is often temporary information, so the period for which it is desired to be bookmarked is often short, unlike tweets or the like in a field one is interested in.

It is preferable to store the traffic congestion tweets in the electronic device 10 without mixing such traffic congestion messages (tweets) and interest field messages (tweets). In this way, in this embodiment, it is preferable to have a function to change the storage location of the message to a different location physically (locally, spatially).

Alternatively, when the control unit 100 recognizes the information about the storage period by voice, the control unit 100 may store the information for that period and then delete the information.

For example, the control unit 100 changes the storage period between "save this message for a while" and "save this message carefully". The former is deleted after one week, but the latter may not be deleted. In addition, when a specific period is specified, the control unit 100 deletes after the period has elapsed. Tweets recognized as "save this tweet for one week" are saved for one week. For tweets for which a retention period has not been specified, it is advisable to save them using the service's bookmark function.

Also, the type of bookmark to be saved may be changed. For example, the storage period may be changed according to the importance of the message.

In this way, the user can save messages output by voice input as bookmarks. For example, when the user wants to check the output message again or use it later, the message may be saved in the bookmark when the user utters a command indicating the content to be saved in the bookmark. In addition, since the user can perform the registration operation by voice, the output message can be saved as a bookmark even in an environment in which the user cannot perform the operation, such as when the user is driving. Bookmarking means saving a message as information such as favorites. The location where messages are saved as bookmarks may be, for example, a device, but may also be on a messaging service. Messages may also be saved as bookmarks on other devices connected to the device. In addition, a message (eg, message information) itself may be stored as a bookmark, or identification information (eg, a message ID, a URL indicating a message, etc.) specifying the message may be stored.

[1.4.30 Example using audio conference]
A present Example is an Example using a voice conference. For example, the control unit 100 generates a cluster of messages (tweets) with a series of place-and-temporal cohesion for a service that provides an audio conference.

Then, the control unit 100 transmits an invitation message (link information) to a conference room such as a space (preferably providing an audio conference room) to the users in the cluster. Then, in either the service that provides the conference room, the service that provides the messaging service, or the external server device, the contents of the exchanges in this conference room (audio conference room) are transcribed into characters, and the contents of the sentences and the emotions of the voice are recorded. It is preferable to perform a process of determining whether or not the original message is to be distributed by recognition or the like, or notifying the address of this conference room to users who are interested in the distributed tweet. This allows the user to check the situation by voice while driving.

[1.4.31 Electronic equipment]
This embodiment is an embodiment for explaining a method of realizing the device of the electronic device 10 . For example, although the electronic device 10 has been described as an in-vehicle device as shown in FIG. 1, it may be another device. The electronic device 10 may be, for example, a device such as a drive recorder. Further, the electronic device 10 may be realized by, for example, a combination of a substrate of a mirror-integrated drive recorder, which is a drive recorder attached to a rear-view mirror and used, and a liquid crystal.

Further, the electronic device 10 may install an application capable of realizing the functions realized by the control unit in FIG. 8 in the smartphone. Also, the electronic device 10 may be realized by a car navigation device.

[2.3 Flow of processing]
The flow of processing according to this embodiment will be described below. This embodiment is an embodiment in which the management device 20 executes some of the functions of the electronic device 10 described in the first embodiment. In the first embodiment, for example, the management device 20 may implement a part of the functions of the processing described with reference to FIG. 9 . That is, in the first embodiment, the processing implemented only by the electronic device 10 may be implemented via the management device 20 in the second embodiment.

Specifically, the management device 20 acquires a message from the service and posts the message to the service. Electronic device 10 transmits information necessary for generating a message to management device 20 . Also, the electronic device 10 acquires a message from the management device 20 and outputs the message.

That is, in this embodiment, the functions of the electronic device 10 described in the first embodiment are distributed to the electronic device 10 of the second embodiment and the management device 20 as necessary.

For example, the processing of the second embodiment will be described with reference to FIG. First, electronic device 10 executes post information generation processing (S1100). When the electronic device 10 executes the posted information generation process, the electronic device 10 generates posted information based on the state of the vehicle 50, an input from the user, and the like.

The electronic device 10 transmits the generated posted information to the management device 20 (S1102). When receiving the posted information, management device 20 generates a message based on the posted information.

Here, the posted information includes information necessary for generating a message such as the state of the vehicle 50 and information input by the user. The management device 20 determines that the state of the vehicle 50 is congested, for example, according to the moving speed, moving distance, and position information of the vehicle 50 included in the posted information. Then, management device 20 generates a message to the effect that there is a traffic jam from the posted information.

Further, if position information is included in the posted information, management device 20 may generate a map image from the position information. Further, if the posted information includes an image (for example, a captured image of the display screen of the display unit 120 of the electronic device 10), the management device 20 may generate a message including the image.

Also, the management device 20 may generate a new message from the message information stored in the message information storage area 224 .

Management device 20 executes a message posting process (S1300). Specifically, management device 20 transmits the generated posted message information to service providing device 30 . Thereby, the message is posted to the service via the management device 20 .

Also, the management device 20 executes message control processing at a predetermined timing (S1400). The message control process generates a new message based on the obtained message information and executes a message obtaining process for obtaining a message from the service (S1450).

Then, the acquired message information is received as an acquired message information response from the service providing apparatus 30 (S1454).

The management device 20 transmits the message information to the electronic device 10 based on the obtained message information (S1460). The electronic device 10 executes message output processing (S1500). In the message output process, the message included in the message information received from the management device 20 is displayed on the display unit 120 and the voice is output from the voice output unit 130. FIG.

[2.4 Example]
The examples of this embodiment can be applied as they are to the examples described in the first embodiment. That is, among the processes performed by the electronic device 10 , message generation, message posting, message acquisition, and message control may be realized by the management device 20 as appropriate. For example, in the first embodiment, the contents of the message generated by the electronic device 10 can be directly implemented by the management device 20 .

Also in the second embodiment, the electronic device 10 may generate the message. In this case, the posted information may include the message to be posted as a text. Then, management device 20 may generate posted message information in a format that is actually posted in a message.

As described above, the example described in the first embodiment can be applied to the second embodiment, but the example in the second embodiment will be described below for convenience. It goes without saying that the following examples may be applied to the first embodiment and implemented in the electronic device 10 .

[2.4.1 Example of generating and posting a message]
A present Example is an Example which posts a message to a service from the electronic device 10 at arbitrary timings.

For example, the display unit 120 of the electronic device 10 has categories of "accident", "traffic jam", "dangerous driving", and "disaster". to generate

For example, "I'm stuck in a traffic jam at an intersection" is selected from the word list of "traffic jam". Note that the message may include a pictogram of a plurality of cars lined up indicating a traffic jam. Also, a tag based on an address or road name may be added to the message.

At this time, post information including the date and time, address, road name, and message is transmitted from the electronic device 10 to the management device 20 . Note that if the account information is already held in the electronic device 10, login authentication may have already been performed in the service, or authentication may be performed in the service each time.

Management device 20 generates a message based on the content included in the posted information. For example, FIG. 18A shows an example of a generated message. Also, at this time, if image data is included from the electronic device 10, the image data may be included in the message. Here, the image data included in the message may include the image data itself in the message, or may include the URL where the message is uploaded.

The management device 20 posts a message on the service using the interface of the service. For example, if the service is Twitter, the message is tweeted using the Twitter API.

FIG. 18(B) is an example showing a state posted to practice. In this case, the account that posted the message may be an account owned by management device 20 (that is, an account for posting used in the system, regardless of the account of electronic device 10), or an account of the user of electronic device 10. can be an account.

Also, when the message is posted using an account owned by the management device 20, the message may include an account mention indicating the user who posted the original message. This allows other users to confirm from whom the information is based.

Also, by posting a message using an account held by the management device 20, other users can obtain information including traffic information by obtaining the message of the account.

A specific operation in the case of including image data will be described below. First, the electronic device 10 generates a text file (for example, “20100428010101.txt”) using a message to be posted in the posted information as text data. The electronic device 10 transmits (uploads) the text file, which is wording data, to the management device 20 .

It also generates image data to be posted (for example, “20210428010101.jpg”). The image data to be posted is transmitted (uploaded) to the management device 20 with an extension format of PNG, JPG, or GIF.

Management device 20 functions as a post server. For example, the management device 20 is installed with posting software composed of PHP or the like. Then, it circulates through folders containing posted data (posted information), and posts wording data (text data) and image data to the service. At this time, the management device 20 needs to undergo access key authentication for the twitter API. Also, the management device 20 may use an HTTP response status code when posting.

Also, the management device 20 may generate an image based on other information. For example, if the posted information includes latitude and longitude information, map image data may be generated based on the latitude and longitude information. By generating map image data in the management device 20, an image based on the latest map can always be generated.

[2.4.2 Distributing acquired messages to services and electronic devices]
This embodiment is an embodiment in which a new message is generated from the message acquired by the management apparatus 20, and the electronic device 10 can display a telop or post it to a service.

For example, the management device 20 acquires a related message (Tweet information) from a search word using a service interface (for example, TwitterAPI). Then, the management device 20 once stores the acquired message in CSV format. Here, the keywords, which are search words, are preferably traffic-related keywords.

For example, FIG. 19 is a diagram showing an example of stored CSV information. The management device 20, for example, extracts a keyword related to the accident from the top message. From this message, we can see that it was an "accident" and that the accident occurred in "Oto-cho, Sasebo City". Therefore, as a message to be distributed (for example, a posted message to be posted to a service), a message "<Accident traffic jam> 1 hour ago, Oto-cho, Sasebo-shi, truck accident" is generated. The management device 20 may deliver this generated message to the electronic device 10 . When the electronic device 10 acquires the message, it can display a telop. Also, the management device 20 may post the generated message to a service. Also, when posting to a service, the message may be posted to the service with the account of the person who posted the message (here, @yakyu) included in the message.

The second message from the top in FIG. 19 is a message indicating that an accident has occurred. On the other hand, the third and fourth messages are reposts (RTs) of the second message. In this case, management device 20 may generate a message to be distributed based on the second message. That is, the management device 20 may determine that the second to fourth messages are related messages.

For example, the management device 20 generates a message “<accident traffic jam> 30 minutes ago Chugoku Expressway outbound accident near Takarazuka Interchange” and delivers it to the electronic device 10 . At the same time, the message is posted to the service.

At this time, the management device 20 may determine whether or not the message has been delivered to the electronic device 10 . For example, the second message from the top in FIG. 19 is a reposted message and has a high degree of importance. Therefore, it distributes to the electronic device 10 and posts the message to the service. However, the first item in FIG. 19 has not been reposted by another user. In this case, for example, the message may be posted to the service but not delivered to the electronic device 10 .

Thus, according to this embodiment, the management device 20 can regenerate a post message based on the acquired message and post it to the service. Management device 20 can also deliver the posted message to electronic device 10, and electronic device 10 can output the received posted message.

Also in the present embodiment, the method described in the first embodiment may be applied to the method of summarizing messages and the method of determining the reliability of messages, for example.
