Description

  The present invention relates to an information providing apparatus and an information providing method.

  In recent years, SNS (Social Networking Service) has become widespread as a service for realizing communication between users on the Internet. In SNS, a message can be sent to a large number of specific or unspecified users, and the user can directly send a message from the terminal or send information collected by a program or device automatically. Is possible.

  An example of a technique in which a device automatically sends a message is a mailbox described in Non-Patent Document 1. According to this technique, when a mail piece is posted, the arrival of the mail piece and the type of the mail piece can be notified to the user via Twitter (registered trademark) which is a kind of SNS.

  Further, although the target is not SNS, there is a technology in which a communication terminal automatically transmits its current position to others by automatically transmitting GPS position information to a network (Non-patent Document 2). According to the technology, the service provider can always grasp the current location of the user, so that it is easy to distribute information according to the location and area, such as weather forecasts, event information, and tourist information. Become.

Mizushima, Yuji, Tsukada, Koji, Shiio, Ichiro, “Postal Arrival”, Information Processing Society of Japan, Human Computer Interaction (2010-HCI-137), No. 7, pp.1-6, 2010.3.19 "Auto GPS", [online], NTT Docomo, [October 7, 2011 search], Internet <URL: http://www.nttdocomo.co.jp/service/information/auto_gps/>

  There is a desire to transmit information through SNS even while driving a car. In the conventional form, when it is desired to send information about where and what is being done via the network, it is necessary to stop the car and operate the portable terminal to actively send information. For this reason, SNS users who are driving a car cannot participate in communication even when SNS is widely used and who knows where and what can be done easily.

  In order to solve this, a form in which a communication device mounted on an automobile automatically transmits information to the SNS is conceivable. However, according to the prior art, the communication device can only transmit the information it has to the network as it is. For example, in the technique described in Non-Patent Document 1, the fact that a mail piece has arrived and information on the mail piece detected by the sensor and the camera can be transmitted. It is not possible to notify anything other than information.

Further, according to the technique described in Non-Patent Document 2, it is possible to notify a user's position information to a third party via a network. However, in this technique, simple information such as latitude and longitude is determined at a predetermined timing. You can only send information. For this reason, the user who has acquired the information cannot specifically imagine where the target vehicle is, and cannot know the state of the vehicle.

  As described above, in the prior art, there is a mechanism in which a device automatically sends a message to a network. However, for example, only the facts such as “current position” and “registered mail have arrived” are sent as they are. There was no device that autonomously created and sent messages by replacing the surrounding situation with easy-to-understand words for the purpose of interacting with other users.

  The present invention has been made in consideration of the above-mentioned problems. A message is created with words close to human expression from the acquired sensor information, and communication is made with other users by speaking automatically. It is an object of the present invention to provide an information providing apparatus capable of providing information.

  In order to achieve the above object, in the information providing apparatus according to the present invention, a message is created from the acquired sensor information and transmitted by the following means.

  The information providing apparatus according to the present invention includes sensor information acquisition means for acquiring sensor information that is information read by the sensor device from the connected sensor device. Sensor devices include GPS for acquiring position information, vehicle speed sensors, switches such as turn signals and wipers, acceleration sensors, throttles and steering sensors, inter-vehicle radars, illuminance meters, rain gauges, and other vehicle conditions and vehicles It is a device that can acquire the surrounding state. For example, if the apparatus is mounted on a vehicle, the sensor information may be information such as the current position and speed of the host vehicle, or may be information such as weather and the density of surrounding vehicles. The sensor information may be any information that can be read by a device that can acquire information, such as the genre of music flowing in the vehicle and the video of an in-vehicle camera. Further, the installation destination of the device is not limited to the vehicle.

  In addition, the information providing apparatus according to the present invention includes an event selection unit that determines an event that is currently occurring based on the acquired sensor information, and a keyword that is readable based on the determined event and the sensor information. Keyword generating means for generating. An event is information for identifying one's own situation or surrounding situation that can be derived from sensor information such as “in a specific area”, “congested”, “raining”. The keyword is a sensor information converted into readable information, such as “40 km / h” for the vehicle speed pulse signal and “near Tokyo Skytree” for the latitude / longitude information. The read value is replaced with a word that is easy for the user to understand. For example, an event “Registered landmark is in the vicinity” is selected from position information that is one of the acquired sensor information, and a keyword “Tokyo Sky Tree” is determined from the selected event and position information. With this configuration, it is possible to generate information on what is happening now and what the details are.

In addition, the information providing apparatus according to the present invention includes a message template storage unit that stores a message template in which a template of a message to be transmitted to the network is defined;
A message template selection unit that selects the message template corresponding to the determined event, the message template selected by the message template selection unit, and a transmission message that generates a message from the keyword generated by the keyword generation unit It has a production | generation means and a message transmission means which transmits the produced | generated transmission message to a network. The message template is a type of message to be transmitted to the network, and a message template corresponding to each event is defined.

  For example, if the event is “the registered landmark is in the vicinity”, the message template “currently running near XX” is selected. By combining the determined keyword with the selected template, it is possible to generate a message to be transmitted such as “Now traveling near Tokyo Skytree”.

  The message template selection unit may select the message template in consideration of the keyword generated by the keyword generation unit.

  With this configuration, it is possible not only to select a message template corresponding to each event, but also to select a more appropriate message template depending on the content of the keyword.

  The information providing apparatus according to the present invention is an information providing apparatus mounted on a mobile body, further comprising landmark data in which a correspondence between a landmark name and position information is defined, and the sensor information is , Including the position information acquired from the GPS device possessed by the mobile body, and when the event selecting means selects an event of approaching a predetermined position, the keyword generating means A landmark name in the vicinity of the moving object is determined as a keyword from the mark data, and the transmission message generation unit generates a transmission message by inserting the landmark name into a message template that informs position information. It is good.

  By having data in which location information and landmark names are associated, the location information acquired by the GPS device can be replaced with words such as base names and area names. Can create messages that are easy to understand. The landmark is not limited to a building or the like, and may be information such as a region name, a mountain, a port, a lake, or the like where the current position can be imagined.

  The event selection unit may further generate a parameter indicating a pseudo emotion based on the sensor information, and the transmission message generation unit may change the transmission message based on the pseudo emotion. .

  Pseudo-emotion is a pseudo-expression of the emotion that the device has depending on the situation. For example, if the sensor information indicates the occurrence of a traffic jam, a negative emotion is selected, and a message is selected based on the selected emotion. With this configuration, a message closer to a human can be created. The message change refers to adding an emotion expression to the generated message by means such as adding a sentence or changing the ending or tone.

  The information providing apparatus according to the present invention further includes a preference data storage unit that stores a user's preference, and the keyword generation unit preferentially applies the keyword that matches the user's preference. May be a feature.

  The preference data is data that holds the hobby / preference of the driver. For example, if the driver has a preference for gourmet information, the keyword “Yokohama Chinatown” is applied in preference to the keyword “Yamashita-cho, Naka-ku, Yokohama-shi”. With this configuration, it is possible to make a remark that suits the personal preference.

Further, the event selection means determines an operation command for an external device from the acquired sensor information, issues the operation command to the external device, and the transmission message generation means sends the issued operation command The processing result corresponding to the above may be generated as a transmission message.

  The operation command is command information and destination information for operating an external device such as an in-vehicle camera connected to the information providing apparatus according to the present invention, and corresponds to, for example, a shooting command of the in-vehicle camera. With this configuration, it is possible to make an operation request to a connected device, such as taking a picture at a timing approaching a registered landmark, and transmit the result together with a message.

  The information providing apparatus according to the present invention may transmit a message to a social networking service through the network. By transmitting the determined message as “tweet” or “diary”, it is possible to communicate with other users.

  According to the present invention, it is possible to provide an information providing apparatus capable of communicating with other users by creating a message using words close to human expression from acquired sensor information and autonomously speaking. Can do.

(First embodiment)
The information providing apparatus according to the first embodiment is an in-vehicle information providing apparatus mounted on an automobile. FIG. 1 is a block diagram illustrating a configuration of the in-vehicle information providing apparatus according to the first embodiment, and FIG. 2 is a flowchart of the in-vehicle information providing apparatus according to the first embodiment. The in-vehicle information providing apparatus 10 includes a sensor group 11, a sensor information acquisition unit 12, an event selection unit 13, a keyword generation unit 14, a transmission message creation unit 15, and a network transmission / reception unit 16, and the event selection unit 13 includes event data. 13a, the keyword generation unit 14 has keyword data 14a, and the transmission message creation unit 15 has a message template 15a. The operation of the in-vehicle information providing apparatus according to the first embodiment will be described with reference to the block diagram of FIG. 1 and the flowchart of FIG.

The sensor group 11 is a sensor device group provided for collecting information on the vehicle and the vehicle periphery. This sensor group is constituted by a plurality of sensors for acquiring the state of the vehicle or the state around the vehicle, such as the vehicle speed, parking brake, turn signal, and steering. The sensor group may include a GPS device for acquiring the current position (latitude / longitude) of the vehicle, or may be connected to an in-vehicle camera, an in-vehicle music player, or the like. Information such as images acquired from the in-vehicle camera and album and track numbers being reproduced by the in-vehicle music player can also be handled as sensor information. Information acquired by the sensor group 11 is sent to the sensor information acquisition unit 12. In transmission, a signal can be transmitted by a predetermined communication means. For example, it may be sent by communication means such as an in-vehicle LAN (Local Area Network).

  The sensor information acquisition unit 12 is means for acquiring information sent from the sensor group 11, and is sensor information acquisition means in the present invention.

  The event selection unit 13 is a means for selecting a state of the vehicle or a state around the vehicle (hereinafter referred to as an event) based on the acquired sensor information, and is an event selection means in the present invention.

  The event selection unit 13 has event data 13a. In the event data, for example, events that can be acquired from the sensor information such as “running in a specific area”, “in a traffic jam”, and “raining” are defined in association with the sensor information. An example of event data is shown in FIG. If the input sensor information matches all of “condition 1” to “condition 3”, the event defined in the “event” column is selected. Thereby, the event selection part 13 can determine the kind of event which wants to transmit to a user based on sensor information.

  The keyword generation unit 14 is a keyword generation unit in the present invention, and is a unit that creates a keyword obtained by converting sensor information into readable information based on the event selected by the event selection unit 13. The keyword generation unit 14 has keyword data 14a. The keyword data is information for converting the acquired sensor information into readable information, and is different for each corresponding event. For example, when an event “near a specific landmark” is selected, keyword data for converting the position information into the name of the area or the name of a landmark existing in the vicinity is selected, and the position information is input. By doing so, the name can be obtained.

  An example of the keyword data is shown in FIG. In the keyword data illustrated in FIG. 4A, the position information is associated with the name of a landmark or area existing near the position, and the genre. The latitude / longitude information acquired by the GPS device is associated with the keyword data. Can be converted to a name. Moreover, if the keyword data illustrated in FIG. 4B is used, the remaining fuel amount and the travel distance, which are sensor information, can be converted into a keyword of a travelable distance. Thus, the keyword data may be anything as long as the sensor information can be converted into readable information.

  With the above configuration, the event selection unit 13 and the keyword generation unit 14 can select an event to be transmitted to the user based on the sensor information, and generate detailed information describing the selected event.

  The transmission message creation unit 15 is a means for creating a message to be transmitted to the network from the selected event and the generated keyword. The transmission message creation unit has two roles. One is a means for selecting a message template corresponding to the event selected by the event selection unit 13, and corresponds to the message template selection means in the present invention. The other is a means for generating a message by inserting the generated keyword into the determined message template, and corresponds to the transmission message generating means in the present invention. Each will be described.

The transmission message creation unit 15 has a message template 15a. It is a message template storage means in the present invention. The message template is data in which a template of a message corresponding to the selected event is defined.
A word to be transmitted to S is defined. An example of the message template is shown in FIG. The message template illustrated in FIG. 5 defines the correspondence between events (and supplementary information) and message templates. The transmission message creation unit 15 selects a message template to be used from the selected events, and creates a final transmission sentence by inserting a keyword as necessary.

  The network transmission / reception unit 16 is a means for transmitting the created message, and is a message transmission means in the present invention. For example, it has a communication means that can be connected to the Internet, and can log in to a vehicle account provided in the SNS and post a message. It is also possible to acquire a reply message transmitted from another user to the vehicle account.

  Next, the operation of the apparatus will be described in detail with reference to FIG. 2 which is a flowchart of the in-vehicle information providing apparatus according to the first embodiment. When the apparatus starts operation, it is checked whether a certain time has passed since the previous message transmission, and if not, the apparatus waits until the condition is satisfied (S11). Next, sensor information is acquired from the sensor group 11 (S12). In the present embodiment, the sensor information includes the current position (latitude / longitude) of the vehicle that can be acquired from the GPS device.

  Next, a corresponding event is selected from the acquired sensor information and event data 13a (S13). When the event data shown in FIG. 3 is used, if the condition “the landmark defined in the keyword data is near” is met, the event “landmark approach” is selected, and the fuel remaining amount is 5 L or less. In some cases, the event “near fuel shortage” is selected.

Next, a keyword corresponding to the selected event is acquired (S14).
When the event “landmark approach” is selected in step S13, a keyword is acquired using keyword data (referred to as landmark data) in which position information is associated with a landmark name. FIG. 4A shows an example of landmark data. For example, when the current position of the vehicle is in the vicinity of 35.451 degrees north latitude and 139.634 degrees east longitude, the keyword “Yokohama Landmark Tower” is acquired, and the information “genre: tower building” is also acquired.

  When the event “near fuel shortage” is selected, a keyword is acquired using keyword data in which the remaining amount of fuel is associated with the travelable distance. FIG. 4B is an example of keyword data for generating a travelable distance. For example, when the tank capacity is 45 L, the remaining fuel amount is 5 L, and the travel distance from the previous refueling is 500 km, the keyword “62.5 km” is acquired. As described above, the keyword data may be anything as long as the sensor information is associated with the information that can be understood by the user.

  In the processing of steps S13 and S14, only the event may be determined without determining the keyword. For example, when the average speed for the latest 5 minutes is 30 km / h or more and the number of stops is 5 or less, an event “signal waiting” occurs. Since there is no corresponding item in the keyword data, no keyword is acquired.

  In step S15, it is confirmed that the event or keyword has been properly selected. If there is no event and keyword corresponding to the acquired sensor information, the process returns to step S11. If there is a previously transmitted message, it is confirmed whether the selected event or keyword is different from the previous one (S16). If the same item is selected, the process returns to step S11.

  Next, the transmission message creation unit 15 selects a message template corresponding to the selected event from the message template 15a, and creates a message by inserting the generated keyword into the selected message template (S17). . Here, the selected event is “landmark approach”, and the keyword is “Yokohama Landmark Tower”. Since the genre of Yokohama Landmark Tower is “Tower Building”, the message template to be selected is “Ah, that big, (keyword name)?”. The transmission message creation unit 15 inserts the keyword “Yokohama Landmark Tower” in the keyword name portion, and the message to be created is “Ah, that big, Yokohama Landmark Tower?”. If the genre is “Gourmet”, the message created will be “Yokohama Chinatown passing. Are you hungry?”

  In this embodiment, the message template is selected using the event “landmark approach” and the genre information corresponding to the keyword “tower building”, but the information defined together with the keyword is The message template may be selected using only the event without using it.

  Further, the selected event may be irrelevant to driving. For example, when music is played by an on-board music player and the genre is jazz, the event “BGM with atmosphere” is selected. By acquiring a song name from a music player and using it as a keyword, a message such as “BGM is (song name). Good atmosphere.” Can be created.

  The created message is transmitted by the network transmitting / receiving unit 16 (S18). As described above, the vehicle has a unique account, and by posting to a service such as SNS, it is possible to obtain an effect as if the vehicle is muttering.

  The fixed time described in step S11 may be a random time, or the waiting time may be changed depending on the time zone, for example, a message transmission interval becomes longer at midnight.

  In addition, a voice input device or the like may be connected to the sensor information acquisition unit. For example, when there is an input from a voice input device, an event “driver utterance” may be selected, and the content input by voice may be transmitted as a message. In this case, by setting the result of speech recognition as a keyword, it becomes possible to create a message such as “The driver says something.“ (Keyword) ”. In this way, the driver can transmit an arbitrary message to the SNS without interrupting the driving operation.

  By configuring as described above, communication with the outside of the vehicle, which could not be conventionally performed during driving, becomes possible. In addition, by giving an account to the vehicle and letting it speak autonomously with words close to human expressions, it is possible to create an environment where other users can easily talk.

(Second embodiment)
In the second embodiment, in addition to the first embodiment, a process other than message creation is performed on a device that the vehicle has. The system configuration diagram of the second embodiment is shown in FIG.

The in-vehicle information providing apparatus according to the second embodiment has a function of operating the in-vehicle device 17 based on the selected event. FIG. 7 is an example of the event data 13a according to the present embodiment. Compared with the event data used in the first embodiment, the definition of external processing is added. The configuration other than the device 17 and the event data 13a is the same as that of the first embodiment.

  In the first embodiment, an event corresponding to the sensor information is selected in step S13. In this embodiment, an operation command is issued to the corresponding external device simultaneously with the selection of the event. For example, the operation command is a request that can be issued to a device that the vehicle has, such as a still image acquisition request issued to an in-vehicle camera or a traffic information acquisition request issued to an in-vehicle communication device. It may be a thing. In the example of FIG. 7, when the condition “the landmark defined in the keyword data is near” is met and “genre = place where the sea can be seen” is selected, the event “the sea was seen” is selected. At the same time, a still image video is acquired from the in-vehicle camera and attached to the created message.

  In this way, by sending a request to the equipment of the vehicle according to the selected event and sending the processing result as a message, it can behave as if the vehicle has a personality. It becomes possible.

  Further, as exemplified in the first embodiment, an external device can be operated by a driver's voice input by connecting a voice input device to the sensor information acquisition unit. For example, when the word “photographing” is input from the voice input device, an event “photographing request” may be selected, a still image may be captured by the in-vehicle camera, and transmitted to the SNS.

(Third embodiment)
In the third embodiment, in addition to the first embodiment, a pseudo emotion is selected to decorate a message. The system configuration of the third embodiment is the same as that of the first embodiment. In addition, only differences will be described for the processing.

  FIG. 8 is an example of event data according to the third embodiment. In addition to the event, the event data shown in FIG. 8 includes a parameter “emotion”. This is information that defines what kind of emotion the vehicle has from the input of the sensor in order to give a human impression to the message issued by the vehicle. For example, when the average speed for the latest 5 minutes is 15 km / h or less, an event “congested” is selected and an emotion “unlucky” is selected. On the other hand, when the wiper is operating further, it has rained in addition to the traffic jam, so the event remains “medium traffic” and the emotion changes to “worst”. Since the selected “emotion” is a parameter for giving a human touch, it is not used for information transmission, but is used for message decoration such as changing the ending of a message or adding a word.

  In the processing step S17 in the first embodiment, the created message can be changed or modified using the selected emotion. FIG. 9 shows a message template 15a in the third embodiment. If the selected event is “low signal waiting” and the emotion is “fun”, in the first embodiment, a message “Today signal connection is good!” Is generated that represents the event. However, you may connect the message “Fuufufu ♪” to express your feelings. As mentioned earlier, “emotion” is a parameter that gives the message a human touch. By connecting two messages, you can express “information linked to the event” and “emotion”. Natural sentences can be generated.

Note that either one of the message representing the event and the message representing the emotion may be transmitted, or only the emotion may be transmitted as a message at a timing not applicable to any event. When only feelings are transmitted, a message may be transmitted at a completely random timing. As for emotions, if a plurality of messages are defined for the same emotion and are selected at random, it is possible to create a more natural message because the same content is not repeated.

  Moreover, the expression of emotion may change not only the connection of messages but also the generated message itself. For example, if an emotion of “fun” is set for an event “approaching destination”, the message “You are about to arrive (keyword name) soon! If you have the feeling, “Finally arrived at (keyword name! Sleepy! Tired!”). As described above, the content of the generated message may be different depending on emotions.

  Although not used in the description of the present embodiment, the message template of FIG. 9 illustrates the item “personality type”. This expresses the setting that the personality is different depending on the vehicle. For example, “personality A” has a high tension and “personality B” is easy to use. Of course, the personality type may be switched depending on the time zone in the same vehicle, or the personality may change when entering the expressway.

(Modification)
The above description is merely an example for explaining the present invention, and each embodiment can be modified without departing from the gist of the present invention. For example, in the description of the embodiment, the information providing apparatus has been described as being mounted on the vehicle. However, the information providing apparatus may be a fixed device and sensor information may be collected from a moving body. In this case, the in-vehicle information providing apparatus 10 can be replaced with a fixed computer, and the sensor group 11 can be replaced with a vehicle. The information providing device is connected to the vehicle by a wireless communication line or the like.

  In the description of the embodiment, the example in which the information providing device 10 is mounted on the vehicle and the position information by the GPS device is used has been described, but the information providing device may not be provided in the vehicle. For example, it may be a ship or a fixed weather observation device. Further, the position information is not necessarily used.

  In the description of the embodiment, “event”, “keyword”, and “emotion” are defined in the output of the event selection unit. However, other items may be added, and the output is not used as it is. May be. For example, when a plurality of events and emotions are applicable, the final output content may be determined by calculating a value.

  In the description of the embodiment, an example in which a message is transmitted to the SNS has been described. However, the present invention may be applied to other services as long as information can be transmitted through the network.

  In addition, when the information providing apparatus according to the present invention is mounted on a vehicle, a database that records the driver's preferences may be prepared so that information that does not match may not be transmitted, or information that matches may be transmitted preferentially. You may make it do. For example, it may be defined that “when a plurality of events are applicable, priority is given to gourmet information over hot spring information”. FIG. 10 shows an example in which priority is added to keyword data. When matching with a plurality of items, the keyword generating unit 14 preferentially extracts keywords having high priority. The priority column included in the keyword data is the preference data storage means in the present invention. A priority with a small value may be preferentially selected, or selection may be suppressed by setting a specific value.

Further, information that can be referred to when creating a message may be added. For example, a means for storing a travel history may be added so that information similar to information transmitted in the past may be preferentially transmitted, or a geographical database or music database that is more detailed than the keyword data in FIG. You may do it.

  In the description of the embodiment, a message in a form that can be easily read and understood by other users is created. However, a message that is processed by another computer may be transmitted. For example, it is possible to determine the rain region by transmitting information that the wiper is operating to the information collection server together with the position information. If traffic jam information is transmitted, it can be used for traffic control. In this way, the transmitted information may be processed by a computer.

  In the description of the embodiment, an event is selected using the event data 13a. However, if an event to be notified is fixed, the event data may not be used. For example, if you want to notify only location information, you can create a message and send it by inserting only a keyword (landmark name) after fixing the template of the message to be sent without selecting an event. Aim can be achieved.
