DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram showing a configuration of a mobile content providing system according to a first embodiment of the present invention.
This system is configured as an in-vehicle system 10 installed in an automobile. The in-vehicle system 10 includes an information processing device 11 that forms the center of the system, and an input device 12, a current location acquisition device 13, a tuner 14, a media driver 15, an output device 16, and a communication device 17 connected to the information processing device 11.

[0011]
The information processing apparatus 11 includes a route creation / guidance unit 111, a scenario generation / correction unit 112, and a content selection unit 113 as functions realized by the operation of a predetermined program.
[0012]
The route creation / guidance unit 111 implements a navigation function for guiding a vehicle by searching for a route from the current location to the destination, and is configured as shown in FIG. 2, for example. The destination input via the input device 12 and the current location of the vehicle detected by the current location acquisition device 13 are given to the route search unit 1111, and the route search unit 1111 receives the optimum route from the map database (DB) 1112. Explore. At that time, the route may be determined based on an instruction such as a highway priority or a general road priority input separately, or the route may be determined by separately inputting information about a passing point on the way. The required time predicting unit 1113 is a required time from the route searched by the route searching unit 1111 to the destination, or in addition to this, a required time to enter the highway, for example, a required time to get off the highway Calculate the required time to the passing point on the way. In calculating the required time, it is desirable to use a vehicle speed in consideration of traffic jam information and the like separately received by the current location acquisition device 13 in addition to the average vehicle speed. The route attribute detection unit 1114 breaks down the route searched by the route search unit 1111 into shorter segments, and for each segment, the type of road (national road, prefectural road, highway, etc.) and the type of area (city area, Feature attributes such as suburbs, mountainous areas, etc.) are detected based on the data in the map DB 1112. These routes, required time, route attributes, etc. are stored as route information in the route information storage unit 1116, and this route information is output to the output device 16 for navigation together with map data. The route information is also given to the scenario generation / correction unit 112. The traveling state recognition unit 1115 compares the current location information and current time from the current location acquisition device 13 with the route information stored in the route information storage unit 1116, and the deviation from the guided route and the predicted requirement The deviation from the time is recognized as route deviation information and supplied to the scenario generation / correction unit 112.
[0013]
The scenario generation / correction unit 112 has a function of creating and correcting a scenario for determining the optimum content for the user, the provision order and provision timing based on the route information from the current location to the destination. For example, FIG. It is configured as shown. The route information supplied from the route creation / guide unit 111 is input to the scenario configuration / reconstruction unit 1121. The scenario composition / reconstruction unit 1121 includes a series of contents to be provided to the user on the route from the current location to the destination based on the content information evaluated by the content evaluation unit 1122 in addition to the input route information. Then, a scenario that defines the provision order and provision timing is generated. The generated scenario is stored in the scenario storage unit 1124 and supplied to the content selection unit 113. The scenario configuration / reconfiguration unit 1121 also sequentially corrects the generated scenarios based on the path deviation information. The content evaluation unit 1122 has a higher evaluation score that matches the user's preference from the user's preference information stored in the preference information storage unit 1125 or stored in the preference information storage unit 1125 after being received by communication from the outside. Evaluate each content to be Also, the user's current situation from the user situation recognition unit 1123 is received, and the evaluation score is uniformly added (subtracted) and corrected according to the type of each content (music, video, e-mail, etc.). . The user's situation includes, for example, the current user's feelings (happy, sad, etc.), physical condition, passengers (family, children, lovers, etc.), etc. Recognize based on the detected data. In addition, when the user situation changes, the user situation recognition unit 1123 transmits the situation to the content evaluation unit 1122, and the content evaluation unit 1122 performs addition correction of similar evaluation points according to the changed situation. At this time, the user situation recognition unit 1123 notifies the scenario configuration / reconstruction unit 1121 that the situation has changed. When the scenario configuration / reconstruction unit 1121 receives a notification from the user situation recognition unit 1123 that the situation has changed, in addition to the scenario correction due to the path deviation described above, the scenario configuration / reconfiguration unit 1121 refers to the content evaluation unit 1122 And correct the scenario.
[0014]

The output device 16 includes a voice synthesizer that reads out text information by voice, in addition to a speaker for voice output, a display device for image output, and the like. In addition, content correction means such as changing the playback speed of content or generating and playing back a digest so as to match the content playback time instructed from the scenario generation / correction unit 112 may be included. The tuner 14 is a tuner such as FM, AM, or TV. The media driver 15 is a playback driver such as a CD, DVD, MD, cassette tape or the like. As the current location acquisition device 13, a current location detection system using a satellite such as GPS can be typically used. In addition to this, for example, a system that detects its own position from the travel distance and direction inside the system, or a current location is detected outside this system, and this system obtains the position information by broadcast waves or the like. Of course, such a structure may be sufficient. The communication device 17 includes a mobile phone, a wireless telephone device such as PHS, and a short-range wireless device such as Bluetooth.
[0015]
The in-vehicle system 10 is connected to the information center 20 via the communication device 17. The information center 20 is connected to the content servers 40 and 50 via the Internet 30 and is connected to the user's home PC 70 via the Internet 30 and the provider 60. Further, the communication device 17 of the in-vehicle system 10 may be connectable to the home PC 70 via short-range wireless communication such as Bluetooth.
[0016]
Next, the operation of the system configured as described above will be described.
FIG. 4 is a flowchart for explaining the operation of this system.
First, when the user starts the vehicle engine and activates the in-vehicle system 10 (S1), the current location acquisition device 13 acquires the current location and transfers it to the route creation / guide unit 111 (S2). When the user inputs a destination using the input device 12 (S3), the route creation / guidance unit 111 searches for a route from the current location to the destination (S4). This route information is supplied to the scenario generation / modification unit 112, where a scenario is generated (S5).
[0017]
Examples of content that is the basis of the scenario are radio, television program content provided from the tuner 14, music information such as CD, DVD, MD, and cassette tape provided from the media driver 15, video information, and the communication device 17. It includes text, images, audio information received from an external server, route information generated by the route creation / guide unit 111, and the like. Here, for example, in the case of moving picture information compliant with MPEG7, metadata indicating the content and nature of the content is attached, and the music information recorded on the subchannel of the CD is referred to such metadata. The content most suitable for each segment in the route is selected by referring to it. Specific examples of scenario data will be described later.
[0018]
When the scenario is generated, the content selection unit 113 selects a series of contents defined in the generated scenario in a specified order for a specified time and provides it to the user via the output device 16 ( S6). Thereafter, the traveling state recognition unit 1115 periodically monitors the traveling state (S7), and if a deviation occurs in the planned route and the required time, the scenario is sequentially corrected (S8). For example, if a delay in predicted arrival time is detected, an additional scenario is inserted. And if a vehicle arrives at the destination, a process will be complete | finished (S9).
[0019]
Here, an example of the route information will be described with reference to FIG. Assume that a route is searched from the current location A to the destination B via points C, D, and E as shown in FIG. From the route information, it can be seen that the road between A and C is a city road, the required time is 20 minutes, the point A has not passed in the past, the road between A and C is complicated, etc. From these facts, the generation / correction unit 112 determines that navigation from the route creation / guide unit 111 is provided as content from point A to point C. Next, from point C to point D, the scenario generation / correction unit 112 is based on information that the road is a highway, the required time is 30 minutes, and that the user or passenger is a soccer fan. Decides to broadcast last weekend's soccer game from point C to point D with a 30-minute digest. Further, since the points D to E from the expressway are urban areas, the video is stopped, and instead, it is decided to play the latest user's favorite song for 10 minutes. In addition, from point E to point B, as preparation before arriving at home, content is provided that reads out an e-mail addressed to the user with a speech synthesizer. When arriving at the destination home, the information acquisition history in the vehicle is stored in the home PC 70 via the communication device 17, and seamless cooperation between the in-vehicle system and the external device (home PC 70) is achieved.
[0020]
An example of scenario data based on the above route information is shown in FIG. The first column shows the type of content, and the second column shows data for executing the content. The data for executing the content is, for example, the program program ID of the access destination if the content is a program program, the URL address of the access destination if it is a home page on the Internet 30, and the data if it is music. CD name and song name. Of course, the contents of the second column depend on the devices 14 to 16 of the system, and are not limited to this designation method. In addition, each line of the scenario data is in the order of the traveling direction of the vehicle, that is, here, the first line is from point A to C, the second line is from point C to D, and so on. It is registered. In such scenario data, for example, when it is predicted that the point C is not yet reached even after 20 minutes from the point A, the traveling state recognition unit 1115 is stored in the route information storage unit 1116. Based on the route information, it is understood that a delay has occurred, and route deviation information is sent to the scenario configuration / reconstruction unit 1121. Based on this path deviation information, the scenario composition / reconstruction unit 1121 decides to send the same type of content as the current content, refers to the content information of the content evaluation unit 1122, and is registered in the scenario data with the same type. The content information with the highest evaluation score is selected and added to the end of the data for executing the content in the first row and second column of the scenario data. On the other hand, for example, when it is predicted that the vehicle will reach point C in 15 minutes from point A during driving, scenario configuration / reconstruction unit 1121 receives route deviation information in the same manner, Is determined to be deleted, and the deletion is corrected by the amount considered necessary in order from the end of the data for executing the contents of the first row and second column of the scenario data. Further, upon receiving notification of a change in the user situation from the user situation recognition unit 1123, the scenario configuration / reconstruction unit 1121 refers to the evaluation point of each content information adjusted by the content evaluation unit 1122, and if necessary, Correct the scenario data. As described above, the scenario data indicates a series of reproduction contents on the route, and can be dynamically corrected while traveling.
[0021]
Content can also be collected from the Internet 30 via the information center 20, but in this case, useful information scattered on the network is collected using agent technology (for example, Japanese Patent Laid-Open No. 10-149287). can do. In this case, the content can be increased in stages rather than collecting all at once. The scenario generation / correction unit 1121 evaluates the content that has been collected by the content evaluation unit 1122 and generates a scenario. Thereafter, the collected content is evaluated by the content evaluation unit 1122 at that time, and the scenario generation / correction unit 1121 determines whether to modify the scenario such as replacement or addition of the content. If it is known in advance that content will increase in stages, the scenario generation / correction unit 1121 may be operated so as to generate a scenario after predicting content that will be added in the future. . However, when the predicted content cannot be acquired, the scenario generation / correction unit 1121 may replace the content of the part with another content.
[0022]
In this way, in this system, it is possible to provide the optimum content at the optimum timing based on the route from the current location to the destination, so that traveling to the destination is meaningful and enjoyable. it can.
[0023]
In addition, this invention is not limited to embodiment mentioned above.
In the above embodiment, the scenario generation / correction unit 112 is provided in the in-vehicle system 10. However, as illustrated in FIG. 7, the scenario generation / correction unit 21 is provided on the information center 20 ′ side, and the communication devices 22, 17. The scenario may be transmitted to the in-vehicle system 10 ′ via the. In this case, a profile management unit 23 that manages profiles such as the user's name, age, occupation, gender, family structure, and preference information, and the profile registered and updated by the profile management unit 23 are stored in the information center 20 ′. A profile storage unit 24 is provided, and a user profile is registered in advance via the Internet 30 using, for example, a home PC 70. Then, the scenario generation / correction unit 21 generates a scenario based on the route information and user status information transmitted from the in-vehicle system 10 ′ to the information center 20 ′ via the communication devices 17 and 22, and the internal user profile. Then, the scenario is corrected based on the route deviation information transmitted sequentially. In this case, the generated scenario data is a list of access destinations, start times, and end times for each user registration ID.
[0024]
According to this embodiment, since content information can be collected only on the information center 20 'side, there is an advantage that the communication time with the in-vehicle system 10' can be shortened when generating a scenario.
[0025]
In the above-described embodiment, the route is divided at a specific point such as an interchange. However, the route may be roughly divided like a start scenario, an intermediate scenario, and an arrival scenario. Further, a scenario may be roughly selected such as a long-distance outbound path selection scenario, a long-distance return path selection scenario, and a short-distance selection scenario.
[0026]
FIG. 8 is a diagram showing a main part of the configuration of a mobile content providing system according to still another embodiment.
The partial scenario storage unit 81 includes a start scenario, an intermediate scenario, an arrival scenario roughly divided in advance, a long-distance outbound route selection scenario, a long-distance return route selection scenario according to the purpose of rough travel to the destination, Prepare a short distance selection scenario. Each partial scenario includes approximate content candidate information (may be music or movie genre). First, based on the route information and the like, it is extracted from a partial scenario storage unit 81 prepared in advance, and a general scenario is created and synthesized by a general scenario creation unit 82. The created outline scenario is stored in the outline scenario storage unit 83. In the general scenario, required time information of each partial scenario is obtained according to the route information. The general scenario creation unit 82 provides candidate information to the user, for example, by voice or image via the user GUI 84, receives selection information from the user, and determines content candidate information for each partial scenario. The content candidate information determined corresponding to the partial scenario and the time information assigned to each are stored as a schematic scenario. The content selection unit 85 searches content information used for each partial scenario from information content using content candidate information and time information as main search conditions. The content groups searched corresponding to the partial scenarios are combined and stored in the scenario data storage unit 86 as detailed scenario data.
As described above, the scenario to be created may be schematic, and the content selection unit may select the content according to the scenario in detail.
[0027]
【The invention's effect】
As described above, according to the present invention, when the route creation means creates route information from the current location to the destination, the scenario creation means should provide the user from the current location to the destination based on this route information. Since the content scenario is generated, the program can be organized in consideration of the attribute of the route to the destination and the required time.
