[0009] Hereinafter, an embodiment will be described with reference to the drawings. [Example]

[0010] Fig. 1 is an explanatory diagram of device cooperation. Fig. 1 shows an example in which content, which is the execution result of an application program held by one information processing device, is shared among information processing devices present in the vehicle cabin. The information processing devices present in the vehicle cabin include a mobile terminal 30, an in-vehicle device 40, and a rear monitor 50. The mobile terminal 30 is a smartphone terminal, a tablet terminal, etc. carried by the passenger. The mobile terminal 30 is capable of outputting content such as video and music.

[0011] The in-vehicle device 40 is installed in the center of the dashboard, between the driver's seat and the passenger seat. The in-vehicle device 40 has a display unit that can be seen by an occupant in the driver's seat. The in-vehicle device 40 can display map information and route information. The in-vehicle device 40 can also output content such as video and music.

[0012] The rear monitor 50 has a display unit that can be seen by passengers in the rear seats. For example, the rear monitor 50 may be installed on the ceiling of the vehicle cabin or on the backrest of the driver's seat or passenger seat. The rear monitor 50 can output content such as video and music.

[0013] In FIG. 1 , the mobile terminal 30, the in-vehicle device 40, and the rear monitor 50 all have touch panel displays and are capable of outputting content, enabling content sharing. Content sharing is a process in which content managed by one information processing device is output by another information processing device. For example, content sharing can be achieved by transferring video data obtained by executing an application program installed on the mobile terminal 30 or video data stored in the mobile terminal 30 to the rear monitor 50 and displaying it on the rear monitor 50. Data acquired from a content providing service to which the mobile terminal 30 has access rights can also be displayed on the rear monitor 50. In this case, the rear monitor 50 is simply an output device, and the rear monitor 50 does not need to have access rights to the content providing service. Music data stored in the in-vehicle device 40 can also be played on the mobile terminal 30.

[0014] Any of the mobile terminal 30, the in-vehicle device 40, and the rear monitor 50 can be a content source information processing device. Similarly, any of the mobile terminal 30, the in-vehicle device 40, and the rear monitor 50 can be a content destination information processing device. The content destination information processing device may request the provision of content from another information processing device. The content destination information processing device may not only output content, but also accept operations related to the content. In this case, the content destination information processing device temporarily operates as an external input / output device of the content source information processing device.

[0015] 1, the mobile terminal 30 in the back seat outputs content A, the mobile terminal 30 in the passenger seat outputs content B, and the in-vehicle device 40 outputs content C. The rear monitor 50, which is an information processing device to which content is to be provided, displays a screen for selecting content.

[0016] The rear monitor 50 communicates with other information processing devices and displays a content request screen, which is a first screen for requesting content held by the other information processing devices. The content request screen displays icons corresponding to content that can be provided by the other information processing devices. For example, an icon corresponding to the type of content is used as the icon corresponding to the content. If the execution result of the application program is music data, a musical note icon may be used, and if the execution result of the application program is video, an icon resembling a film or video camera may be used. Furthermore, for example, an icon officially used by the content providing service may be used as the icon corresponding to the content. In this case, the data acquired by the application program when accessing the content providing service constitutes the content. Based on the location information of the information processing device, the rear monitor 50 displays, on the first screen, a first area R1 indicating the location of the information processing device itself and a second area R2 indicating the location of the other information processing device. Then, a list of icons corresponding to content that can be transferred from the corresponding information processing device is displayed in area R2.

[0017] In FIG. 1, the rear monitor 50 has an area R1 corresponding to the device itself located near the center of the touch panel. The rear monitor 50 arranges an area R2 based on the relative position of the device itself. Specifically, an area R2-1 corresponding to the in-vehicle device 40 is arranged above and to the left of the area R1. An area R2-2 corresponding to the mobile terminal 30 in the passenger seat is arranged above and to the left of the area R1. An area R2-3 corresponding to the mobile terminal 30 in the rear seat is arranged approximately to the left rear of the area R1.

[0018] In this way, to arrange the areas R1 and R2 according to the relative positions of the devices, the rear monitor 50 acquires the position information of each device. Since the rear monitor 50 and the in-vehicle device 40 are located at fixed positions within the vehicle cabin, it is sufficient to store position information indicating their positions within the vehicle cabin in advance. Since the position of the mobile terminal 30 is not fixed, when communication with the rear monitor 50 is started, the position information at that time is acquired. Identifying the position of the mobile terminal 30 will be described later.

[0019] In the example of FIG. 1, the only content that the in-vehicle device 40 can provide to other devices is content C. Therefore, icon C corresponding to content C is displayed in area R2-1. The contents that the portable terminal 30 in the passenger seat can provide to other devices are content A and content B. Therefore, icon A corresponding to content A and icon B corresponding to content B are displayed in area R2-2. The contents that the portable terminal 30 in the backseat can provide to other devices are content A, content B, content D, and content E. Therefore, icon A corresponding to content A, icon B corresponding to content B, icon D corresponding to content D, and icon E corresponding to content E are displayed in area R2-3.

[0020] The icons used may be, for example, the icons officially used by the content providing service. In the example of Figure 1, icon A and icon B each represent a specific content providing service. That is, icon A in area R2-2 and icon A in area R2-3 represent the same content providing service.

[0021] The operator of the rear monitor 50 can request sharing of content by touching any of the icons and sliding it into region R1. For example, when the rear monitor 50 receives an operation to slide icon B in region R2-2 into region R1, it requests the mobile terminal 30 in the passenger seat to provide content B. The mobile terminal 30 in the passenger seat then receives the request from the rear monitor 50 and transfers content B. The rear monitor 50 receives and displays content B from the mobile terminal 30 in the passenger seat. When sliding icon B into region R1, the image of icon B may be displayed to move in accordance with the sliding operation. Displaying the image of icon B moving to region R1 visually indicates the requested content and the device on which it will be displayed. Even without displaying the image of icon B moving, the requested content can be identified by icon B, which is the starting point of the sliding operation, and the device on which it will be displayed can be identified by region R1, which is the end point of the sliding operation.

[0022] 2 is an explanatory diagram of determining the location of the mobile terminal 30. An in-vehicle device 40 mounted on a vehicle 20 acquires an in-vehicle image and transmits it to a server 10 together with an in-vehicle device ID (1). For example, if an image captured for recording by a drive recorder includes an image of the inside of the vehicle, that image can be used as the in-vehicle image.

[0023] The mobile terminal 30 can communicate with the in-vehicle device 40 via short-range wireless communication and acquire an in-vehicle device ID, which is identification information of the in-vehicle device 40. When a predetermined application is started in the vehicle, the mobile terminal 30 captures a facial image of the user and registers the facial image in the server 10 (2). At this time, the mobile terminal 30 transmits the mobile terminal ID and in-vehicle device ID, which are identification information of the mobile terminal 30, to the server 10 along with the facial image, and the server 10 stores the facial image, the mobile terminal ID, and the in-vehicle device ID in association with the facial image.

[0024] When the server 10 receives the vehicle interior image and the vehicle interior device ID from the vehicle-mounted device 40, it extracts a facial image registered in association with the received vehicle interior device ID. The server 10 performs facial recognition using the extracted facial image and the vehicle interior image. When a facial image matching the face of a person included in the vehicle interior image is identified, the server 10 determines the seating position from the position in the vehicle interior image, and sets this as the seating position of the user of the mobile terminal 30 associated with the facial image. The server 10 notifies the mobile terminal 30 of the seating position (3).

[0025] The mobile terminal 30 receives the seating position notification from the server 10 and stores it as the seating position of the user of the mobile terminal 30. Thereafter, the mobile terminal 30 becomes able to transfer the stored seating position to another information processing device. For example, the rear monitor 50 acquires the seating position from the mobile terminal 30, determines the positional relationship with the rear monitor 50, and determines where on the content request screen to display the area A2 corresponding to the mobile terminal 30. Note that even between mobile terminals 30, each can identify the seating position of its own device and transfer the identification results to each other, allowing the display to be based on the other device's location.

[0026] Fig. 3 is an explanatory diagram showing a specific example of a vehicle interior image. In Fig. 3, vehicle interior image F1 includes images of multiple people's faces. Partial image F2 of vehicle interior image F1 includes an image of the face of a person sitting in the driver's seat, and partial image F3 includes an image of the face of a person sitting in the passenger seat. Similarly, partial image F4 includes an image of the face of a person sitting in the right rear seat, and partial image F5 includes an image of the face of a person sitting in the left rear seat.

[0027] Since the in-vehicle device 40 is fixed to the vehicle 20, the positions of the partial images F2 to F5 in the vehicle interior image F1 correspond to seating positions. Therefore, if a person included in the vehicle interior image F1 is identified using face recognition, the seating position of that person can be determined based on the position of the image of that face in the vehicle interior image F1.

[0028] For example, the rear monitor 50 and the mobile terminal 30 can display partial images F2 to F5 with the upward direction of the display corresponding to the traveling direction of the vehicle. In Fig. 3, partial image F2 corresponding to the driver's seat is displayed in the upper right, partial image F3 corresponding to the passenger seat is displayed in the upper left, partial image F4 corresponding to the right side of the rear seat is displayed in the lower right, and partial image F5 corresponding to the left side of the rear seat is displayed in the lower left.

[0029] 4 is a diagram showing the configuration of the mobile terminal 30. The mobile terminal 30 has a touch panel display 31, a camera 32, a communication unit 33, a storage unit 35, and a control unit .

[0030] The touch panel display 31 is an input / output interface that receives input from the user and displays and outputs the input. In this embodiment, the camera 32 is used to capture an image of the user's face. The communication unit 33 is a communication interface that connects to other information processing devices and the server 10 for communication. The other information processing devices are other mobile terminals 30, in-vehicle devices 40, and rear monitors 50. Communication with the other information processing devices is performed using short-range wireless communication such as Bluetooth (registered trademark). Communication with the server 10 is performed via a mobile wireless communication network, for example.

[0031] The storage unit 35 is a storage device such as a flash memory, etc. The storage unit 35 is a storage unit that stores an application program 35a, a mobile terminal ID 35b, an in-vehicle device, a sharable content list 35d, location information 35e, an icon image 35f, and the like.

[0032] The application program 35a realizes various functions by being executed by the control unit 36. In this embodiment, the application program 35a realizes functions related to sharing of content with other information processing devices.

[0033] The mobile terminal ID 35b is identification information for uniquely identifying the mobile terminal 30. The in-vehicle device ID 35c is acquired from the in-vehicle device 40 and stored when short-range wireless communication with the in-vehicle device 40 is established. Since the in-vehicle device 40 is fixed to the vehicle 20, the in-vehicle device ID indicates in which vehicle the mobile terminal 30 is located.

[0034] The sharable content list 35d is data indicating content (hereinafter referred to as sharable content) that the mobile terminal 30 can provide to other information processing devices. For convenience of explanation, the format of the data is used as a list, but the format is not limited to a list and any format may be used as long as the data indicates sharable content. The sharable content list 35d includes at least the names of the sharable content. In addition to the names, it may also include information indicating the type of sharable content, such as music or video. Examples of sharable content include video data or music data stored in the storage unit 35, and content from broadcasting or distribution services that can be received from an external device and output.

[0035] The position information 35e indicates the seating position received from the server 10. This position information 35e can identify where in the vehicle the user of the mobile terminal 30 is seated. Specifically, the driver's seat, the passenger seat, the right side of the rear seat, the left side of the rear seat, etc. are used as the seating position.

[0036] When the user gets off the vehicle and the short-range wireless communication between the mobile terminal 30 and the in-vehicle device 40 is cut off, it is desirable to delete the in-vehicle device ID 35c and the location information 35e from the storage unit 35.

[0037] The icon image 35f is an icon image corresponding to the content. As an example, an icon officially used by a content providing service is stored as the icon image 35f. The icon image 35f is not limited to content that can be provided by the device itself, and it is preferable to store icons corresponding to content that may be provided from other information processing devices. The icon image 35f is managed in association with the name of the content.

[0038] The control unit 36 ​​is, for example, a CPU (Central Processing Unit) and realizes content sharing by reading and executing the application program 35a. Specifically, by executing the application program 35a, the control unit 36 ​​operates as an acquisition unit 36a, a display control unit 36b, and a transmission unit 36c.

[0039] The acquisition unit 36a acquires location information of one or more information processing devices. Specifically, the acquisition unit 36a establishes communication with other information processing devices and receives location information transmitted by the other information processing devices. The acquisition unit 36a also acquires an in-vehicle device ID 35c from the in-vehicle device 40, acquires a facial photograph of the user from the camera 32, transmits the facial photograph together with the in-vehicle device ID 35c and the mobile terminal ID 35b to the server 10, receives location information 35e of the own terminal from the server 10, and transfers the location information 35e of the own terminal to the other information processing devices.

[0040] The display control unit 36b controls various screens to be displayed on the touch panel display 31. The various screens to be displayed on the touch panel display 31 include a screen that displays content managed by the device itself. The various screens to be displayed on the touch panel display 31 also include a content request screen (first screen) for requesting content held by another information processing device. The various screens to be displayed on the touch panel display 31 also include a screen that displays content acquired from another information processing device.

[0041] When the touch panel display 31 transitions to the content request screen, the display control unit 36b controls the touch panel display 31 to display icons corresponding to content that each information processing device can transfer to the device itself. At this time, the display control unit 36b displays, on the content request screen, a first area R1 indicating the location of the device itself and one or more second areas R2 indicating the locations of the other information processing devices, based on the location information. Then, in the second area R2, a list of icons corresponding to content that can be transferred from the information processing device corresponding to that area is displayed.

[0042] The icon displayed by the display control unit 36b in the second region R2 is an icon image 35f stored in the storage unit 35. The icon image 35f is not limited to an icon of content that can be shared by the display control unit 36b itself, but also includes an icon corresponding to content that can be provided from another information processing device. If the display control unit 36b stores a corresponding icon image 35f for content that can be provided from another information processing device, the display control unit 36b can use the icon image 35f. If the display control unit 36b does not store a corresponding icon image 35f for content that can be provided from another information processing device, the display control unit 36b acquires image data of the icon from another device. At this time, the image data may be acquired from the device that provides the content, or may be acquired by inquiring about another server or the like.

[0043] When the same content can be provided from multiple information processing devices, the same icon will be displayed in multiple areas R2. In this case, the user can select which information processing device will be the provider of the same content, even if the content is the same. On the other hand, when a variety of content can be provided from multiple information processing devices, many icons will be displayed on the content request screen. If the number of icons to be displayed on the content request screen exceeds a predetermined number, the display priority of icons common to multiple information processing devices may be lowered.

[0044] The display control unit 36b determines the display positions of the regions R1 and R2 based on the position information of the other information processing devices and the device itself. As an example, the display control unit 36b determines the layout of the regions R1 and R2 based on the relative positional relationship between the location of the device itself and the other information processing devices. The regions R1 and R2 may also be displayed in association with the location of each device within the vehicle cabin.

[0045] When a touch operation on an icon on the touch panel display 31 is detected, the transmission unit 36c transmits a request for content corresponding to the touched icon to an information processing device that has the content.

[0046] When the touch operation is a slide operation that starts from an icon in area R2 and moves to area R1, the transmitting unit 36c determines the content indicated by the icon that is the starting point of the slide operation as the content to be requested, and transmits a request for the content to an information processing device that has the content.

[0047] FIG. 4 shows the configuration of the mobile terminal 30. In the case of a rear monitor 50, there is no need to identify the location of the device itself based on a facial image of the user, as the location information is provided in advance. Furthermore, a camera is not required. The processes related to providing the location of the device itself and sharing content are the same as those of the mobile terminal 30. In the case of an in-vehicle device 40, there is no need to identify the location of the device itself based on a facial image of the user, as the location information is provided in advance. Furthermore, the camera is used to capture images of the interior of the vehicle. The processes related to providing the location of the device itself and sharing content are the same as those of the mobile terminal 30.

[0048] 5 is a flowchart showing a processing procedure common to all content. After startup, the content requesting information processing device reads its own sharable content list 35d (step S101). Thereafter, the content requesting information processing device establishes a communication connection with surrounding information processing devices (step S102). Thereafter, the content requesting information processing device identifies its own location (step S103). In the case of the mobile terminal 30, identifying its own location is a process of transmitting a user's facial photograph to the server 10 and receiving the seating position. In the case of the in-vehicle device 40 or the rear monitor 50, identifying its own location is a process of reading out pre-stored location information.

[0049] After identifying its own location, the content requesting information processing device exchanges location information with the surrounding devices with which it is connected for communication (step S104).The content requesting information processing device also exchanges a sharable content list with the surrounding devices with which it is connected for communication (step S105).

[0050] Steps S201 to S205 in the information processing device on the content providing side are the same as steps S101 to S105 on the content requesting side. In FIG. 5, for convenience of explanation, the content requesting side and the content providing side are distinguished from the beginning of the process. In reality, there is no distinction between the content requesting side and the content providing side until the sharable content list is transferred. After the sharable content list is transferred, when one of the information processing devices accepts an operation to start a content request, that information processing device becomes the content requesting side, and the other information processing device becomes the content providing side.

[0051] After transferring the sharable content list, the content requesting information processing device accepts an operation to start a content request and transitions to a content request screen (step S106). The content requesting information processing device arranges areas R1 and R2 according to the position of each device (step S107) and arranges an icon in each area R2 (step S108). When arranging the icons, the content requesting information processing device uses the name of the sharable content included in the sharable content list to identify the associated icon image 35f and arranges it in each area R2. In addition to the name of the sharable content, the content requesting information processing device may also use information on the type of sharable content to identify the icon image 35f.

[0052] The information processing device on the content requesting side accepts an operation to select the icon (step S109), identifies the requested content and the information processing device to which the request is to be made, and transmits a content request (step S110).

[0053] When the information processing device on the content providing side receives the content request (step S206), it transfers the requested content to the information processing device on the content requesting side (step S207), and ends the process.

[0054] The information processing device on the content request side receives the content from the information processing device on the content providing side, displays it (step S111), and ends the process.

[0055] Fig. 6 is a diagram illustrating variations in the display of areas. In Fig. 6, an in-vehicle device 40 is placed in the center of the dashboard of a vehicle 20. A rear monitor 50 for the rear seats is installed on the backrest of the driver's seat. The passenger in the front passenger seat and the passenger in the left rear seat are carrying mobile terminals 30.

[0056] Variations of the content request screen when the rear monitor 50 is the information processing device requesting the content are shown as patterns P1 to P4. On the content request screen, area R1 corresponds to the rear monitor 50. Area R2-1 corresponds to the in-vehicle device 40. Area R2-2 corresponds to the mobile terminal 30 in the passenger seat. Area R2-3 corresponds to the mobile terminal 30 in the back seat.

[0057] Pattern P1 is an example in which regions R1 and R2 are arranged based on their relative positions. Specifically, region R1 is arranged in the center of the screen, region R2-1 is arranged above and to the left of region R1, region R2-2 is arranged above and to the left of region R1, and region R2-3 is arranged approximately behind and to the left of region R1.

[0058] Pattern P2 is an example in which regions R1 and R2 are arranged to correspond to the seats of vehicle 20. Specifically, region R1 is arranged in the lower right corner of the screen to correspond to the right rear seat. Region R2-1 is arranged in the upper center of the screen, region R2-2 is arranged in the upper left corner of the screen, and region R2-3 is arranged in the lower left corner of the screen.

[0059] Pattern P3 is an example in which regions R1 and R2 are arranged corresponding to the seats of the vehicle 20, and a blank region R2 is displayed for devices that do not have sharable content. In pattern P3, the mobile terminal 30 in the passenger seat does not have sharable content, and region R2-2 is a blank region with no icons.

[0060] Pattern P4 is an example in which areas R1 and R2 are arranged corresponding to the seats in the vehicle 20, and area R2 is not displayed for devices that do not have shareable content. In pattern P4, the mobile terminal 30 in the passenger seat does not have shareable content, and area R2-2 is not displayed. By making area R2-3 larger to compensate for the absence of area R2-2, it is possible to display a large number of icons for content that can be provided by the mobile terminal 30 in the rear seat.

[0061] Patterns P3 and P4 can also be used in combination with suppressing the display of overlapping icons. If the shareable content on the mobile terminal 30 in the passenger seat is only content A and content B, and the shareable content on the mobile terminal 30 in the back seat includes content A and content B, the display of icons for the shareable content from the mobile terminal 30 in the passenger seat can be suppressed. As a result, there are no icons to be displayed in area R2-2, and the display of pattern P3 or pattern P4 can be adopted.

[0062] Next, the screen of the content to be shared will be described. Sharing methods include Mirroring mode and Extension mode. Mirroring mode is a mode in which the same screen as the screen on the content provider side is displayed on the screen of the content requester side. In this Mirroring mode, the information processing device on the content provider side generates a screen that is the same as the screen displayed on the content requester side and transfers it to the information processing device on the content requester side.

[0063] The Extension mode is a mode in which a screen different from the screen on the content provider side is displayed on the screen of the content requester. In the Extension mode, the information processing device on the content provider side generates a screen to be displayed on the content requester side, separate from the screen displayed on its own device, and transfers it to the information processing device on the content requester. In other words, in either the Mirroring mode or the Extension mode, the screen to be displayed on the content requester side is generated by the information processing device on the content provider side.

[0064] Next, the icon display order will be described. The sharable content list received from another information processing device may be displayed in area R2 in the same order. Alternatively, the sharable content list may be displayed in area R2 based on a predetermined arrangement order. Alternatively, the content provider or requester may be able to specify the order settings.

[0065] Next, the icon filtering function will be described. First, a category is associated with sharable content. The content requester selects a category on the content request screen to hide unnecessary icons from the content request screen. For example, categories such as movies, dramas, animation, and photos are used. If the content requester selects dramas, only icons that can provide dramas are extracted and displayed, allowing the user to easily select the desired icon. Note that the category selection may be configured in advance by the user on a settings screen.

[0066] It is also possible to apply a filter by information processing device or seat. For example, filtering is possible, such as excluding the in-vehicle device 40 from content sources or excluding the mobile terminal in the driver's seat from content sources. The area R2 of the excluded information processing device becomes unnecessary, and the area R2 of the other information processing devices can be enlarged to display more icons. Also, a configuration is possible in which an information processing device that receives a content request asks the operator of its own device for a confirmation operation as to whether it is okay to provide the content. In this case, it is beneficial for the driver's seat occupant to be able to exclude the driver's seat, as it allows them to avoid being asked to perform a confirmation operation that is unrelated to driving.

[0067] As described above, the information processing device (mobile terminal 30, in-vehicle device 40, rear monitor 50) disclosed in the embodiments is a display device having a touch panel, and includes: a communication unit 33 for communicating with one or more information processing devices; an acquisition unit 36a for acquiring location information of the one or more information processing devices; a display control unit 36b for displaying, on the touch panel, icons corresponding to content that the one or more information processing devices can transfer to the display device when the touch panel transitions to a first screen for requesting content held by the one or more information processing devices; and a transmission unit 36c for transmitting, when a touch operation on the icon is detected, a request for first content corresponding to the touched icon to the information processing device that has the first content.The display control unit 36b is characterized in that, based on the location information, on the first screen, a first area indicating the position of the display device and one or more second areas indicating the positions of the one or more information processing devices, and displays, in the second area, icons corresponding to content that can be transferred from the information processing device corresponding to the area. According to this configuration and operation, the positional relationship between the device itself and other information processing devices can be visualized, and intuitive operation regarding which device provides content to which device is possible, improving operability.

[0068] In addition, when the touch operation is a slide operation that starts from the icon in the second area and moves to the first area, the sending unit 36c determines that the content indicated by the icon that is the starting point of the slide operation is the first content, and sends the request to an information processing device that has the first content. According to this configuration and operation, the content provider and the content destination can be specified with a simple operation.

[0069] The device also has a memory unit 35 as a storage unit, and the icons are stored in the storage unit. If there is an icon that is not stored in the storage unit, the display control unit 36b acquires image data of the icon that is not stored in the storage unit from an external terminal. This makes it possible to display any content in an easy-to-understand manner using icons.

[0070] In addition, when the number of icons displayed in the second area corresponding to multiple information processing devices exceeds a predetermined number, the display control unit 36b lowers the display priority of icons common to the multiple information processing devices. This allows the display area to be used effectively and a variety of icons to be displayed.

[0071] In addition, the display device and the one or more information processing devices are located inside the vehicle cabin, and the display control unit 36b displays the first area and the second area on the first screen in association with the seat positions where the display device and the one or more information processing devices are located, respectively, based on the position information. This improves operability when sharing content within a vehicle.

[0072] The present invention is not limited to the above-described embodiments, but includes various modifications. For example, the above-described embodiments have been described in detail to clearly explain the present invention, and the present invention is not necessarily limited to those including all of the described configurations. Furthermore, not only can the configurations be deleted, but also replacements and additions of configurations are possible.

[0073] For example, any method can be used to identify the location of the mobile terminal. As an example, the mobile terminal may transmit a face image to the in-vehicle device 40, and the in-vehicle device 40 may determine the seating position without using the server 10.

[0074] Furthermore, the map and navigation screen displayed by the in-vehicle device 40 can be configured to be displayed and operated by another information processing device.

[0075] Furthermore, the requested content may be determined by tapping the icon instead of sliding the icon into region R1. [Explanation of symbols]
