[Figure 7] Figure 7 shows the configuration of the content distribution system. [Figure 8] Figure 8 shows the configuration of the vehicle display device. [Modes for carrying out the invention]

[0008] [1. First Embodiment] First, the first embodiment will be described with reference to the drawings. [1-1. Content Distribution System Configuration] Figure 1 is a diagram showing the configuration of the content distribution system 1000 according to the first embodiment. The content distribution system 1000 is a system that distributes content to vehicle 1. Examples of content distributed by the content distribution system 1000 include movies, still images, and music. Furthermore, the content distributed by the content distribution system 1000 is content that can be used within vehicle 1. Content that can be used within vehicle 1 is content that can be output to the interior of vehicle 1.

[0009] As shown in Figure 1, the content distribution system 1000 comprises a vehicle 1 and a content distribution server 2. Before describing Vehicle 1, let's describe Content Distribution Server 2. Content Distribution Server 2 is a server device that distributes content. Content Distribution Server 2 is connected to a network NW and communicates with Vehicle 1. The network NW is a communication network consisting of a public telephone network, a dedicated line, or other communication circuits. The Content Distribution System 1000 may have a Content Distribution Server 2 for each content distribution destination. Alternatively, Content Distribution Server 2 may be a server device that aggregates content distributed by multiple content distribution sources and distributes it to Vehicle 1.

[0010] The vehicle 1 illustrated in Figure 1 is a four-wheeled vehicle. Vehicle 1 is equipped with a driver's seat 10A, a passenger seat 10B, a rear right seat 10C, and a rear left seat 10D. In Figure 1, occupant P1, who is the driver, is seated in the driver's seat. In Figure 1, occupant P2, who is a passenger, is seated in the passenger seat 10B. In Figure 1, occupant P3, who is a passenger, is seated in the rear right seat 10C. In Figure 1, occupant P4, who is a passenger, is seated in the rear left seat 10D.

[0011] Vehicle 1 includes a right front door 11A, a left front door 11B, a right rear door 11C, a left rear door 11D, and a tailgate 11E. By opening the right front door 11A, the left front door 11B, the right rear door 11C, and the left rear door 11D, it is possible to enter and exit the passenger compartment space of Vehicle 1. The tailgate 11E opens and closes the trunk of Vehicle 1.

[0012] Vehicle 1 includes a dashboard 12. The dashboard 12 is provided with a touch panel 13 and a speaker 14. The touch panel 13 is composed of a display panel for displaying characters and images and a touch sensor for detecting contact with the display panel, which are superimposed or integrated. The speaker 14 outputs sound to the passenger compartment space of Vehicle 1. The installation position and number of the speakers 14 can be arbitrarily changed. The touch panel 13 is an example of a "display unit".

[0013] A camera 15 for photographing the interior of the passenger compartment of Vehicle 1 is installed in the passenger compartment of Vehicle 1. The photographing range of the camera 15 is set to a range that can photograph the passenger P sitting in the driver's seat 10A and the passenger P sitting in the front passenger seat 10B. More specifically, the photographing range of the camera 15 is set to a range that can photograph the heads (including the faces) of these two passengers P.

[0014] Vehicle 1 includes a shift lever 16 installed near the driver's seat 10A.

[0015] A camera 17 is installed in the passenger compartment of Vehicle 1. The camera 17 is installed, for example, on the back of the driver's seat 10A and photographs the passenger P sitting in the rear right seat 10C. The photographing range of the camera 17 is set to a range that can photograph the passenger P sitting in the rear right seat 10C. More specifically, the photographing range of the camera 17 is set to a range that can photograph the head (including the face) of the passenger P sitting in the rear right seat 10C.

[0016] In the passenger compartment of the vehicle 1, a camera 18 is installed. The camera 18 is installed, for example, on the back of the passenger seat 10B and photographs the passenger P sitting in the left rear seat 10D. The photographing range of the camera 18 is set to a range capable of photographing the passenger P sitting in the left rear seat 10D. More specifically, the photographing range of the camera 18 is set to a range capable of photographing the head (including the face) of the passenger P sitting in the left rear seat 10D.

[0017] The vehicle 1 includes a vehicle display device 19. The vehicle display device 19 outputs the content distributed by the content distribution server 2 by at least one of the touch panel 13 and the speaker 14. The vehicle display device 19 displays various information on the touch panel 13. In the present embodiment, the vehicle display device 19 displays a recommendation screen G for recommending the content that the content distribution server 2 can distribute, in other words, the content that can be used in the vehicle 1. Note that the vehicle display device 19 outputs the content selected on the recommendation screen G into the vehicle 1.

[0018] The vehicle 1 includes a communication device 20. The communication device 20 includes hardware conforming to a predetermined communication standard such as a wireless communication circuit and communicates with the content distribution server 2 connected to the network NW.

[0019] [1-2. Configuration of Vehicle Display Device] Next, referring to FIG. 2, it is a diagram showing the configuration of the vehicle display device 19. FIG. 2 is a diagram showing the configuration of the vehicle display device 19.

[0020] The touch panel 13, the speaker 14, the camera 15, the camera 17, the camera 18, the communication device 20, and the shift position sensor 21 are connected to the vehicle display device 19. Note that the devices connected to the vehicle display device 19 are not limited to these devices, and other types of devices may be further connected.

[0021] The touch panel 13 displays various information according to the control of the vehicle display device 19. The speaker 14 outputs various sounds according to the control of the vehicle display device 19. Cameras 15, 17, and 18 take pictures at predetermined intervals and output the captured images to the vehicle display device 19. The communication device 20 communicates with the vehicle display device 19 and the content distribution server 2. The shift position sensor 21 detects the shift position of the shift lever 16 provided by the vehicle 1. The shift positions include, for example, P (parking) used when parked, R (reverse) and N (neutral) used when reversing, and D (drive) used when driving.

[0022] The vehicle display device 19 includes a processor 100 such as a CPU (Central Processing Unit) or MPU (Micro Processor Unit), a memory 110, and an interface circuit for connecting other devices and sensors. Memory 110 is an example of a "storage unit".

[0023] Memory 110 is a storage device that stores programs and data. Memory 110 stores the first APP 111, the second APP 112, the third APP 113, the control program 114, the crew database 115, and data to be processed by the processor 100. Memory 110 has a non-volatile storage area. Alternatively, memory 110 may also have a volatile storage area and constitute the work area of ​​the processor 100. Memory 110 is composed of, for example, ROM (Read Only Memory) or RAM (Random Access Memory). Control program 114 is an example of a "program".

[0024] App 111 is an application program for using content distributed by a single content provider. APP112 is an application program for using content distributed by a different content provider than APP111. The third app, APP113, is an application program for using content distributed by a different content provider than the first app, APP111, and the second app, APP112.

[0025] The control program 114 is a program that causes the processor 100 to function as a functional unit, which will be described later.

[0026] Crew DB115 is a database containing one record R for each crew member P. Each record R contains facial feature information J1, crew identification information J2, and one or more preference information J3. This record R is created in advance and registered in Crew DB115. In addition, each record R contains one preference information J3 for each type of content preferred by the crew member P. The types of content will be described later.

[0027] Facial feature information J1 represents the facial features of crew member P. Facial features are comprised of multiple items, such as the position of the eye feature points, the position of the nose feature points, the position of the mouth feature points, and the size of the face region.

[0028] Crew identification information J2 is information that identifies crew member P, and may include, for example, information indicating their name, information indicating their nickname within their family structure, or information indicating a uniquely assigned number.

[0029] Preference information J3 indicates crew member P's content preferences. It also indicates the types of content that crew member P enjoys. Furthermore, preference information J3 indicates one or more genres of content that crew member P enjoys.

[0030] The content type refers to categories such as movies, videos, still images, and music. Content genres are a more detailed classification than content types. For example, in the case of movies, genres include action movies, adventure movies, animated movies, documentaries, and horror movies. Similarly, in the case of music, genres include rock, reggae, phonk, and trance. For videos, genres include streaming, product reviews, entertainment, and readings. For still images, genres include Western paintings and Eastern paintings.

[0031] The processor 100 functions as the first content output unit 101 by reading and executing the first APP 111 stored in the memory 110. The first content output unit 101 receives content from the content distribution server 2 via the communication device 20, which corresponds to the first APP 111, and outputs the received content through at least one of the touch panel 13 and the speaker 14.

[0032] The processor 100 functions as a second content output unit 102 by reading and executing the second APP 112 stored in the memory 110. The second content output unit 102 receives content from the content distribution server 2 via the communication device 20, which corresponds to the content distribution source for the second APP 112, and outputs the received content through at least one of the touch panel 13 and the speaker 14.

[0033] The processor 100 functions as a third content output unit 103 by reading and executing the third APP 113 stored in the memory 110. The third content output unit 103 receives content from the content distribution server 2 via the communication device 20, which corresponds to the third APP 113, and outputs the received content through at least one of the touch panel 13 and the speaker 14.

[0034] Hereinafter, when the first content output unit 101, the second content output unit 102, and the third content output unit 103 are not distinguished, they will be referred to as "content output unit 104" with the designation "104".

[0035] The content output unit 104 receives content information along with the content. The content information includes information indicating the type of content, information indicating the genre of content, and image data for the icon image IC. The icon image IC is an image used to select the content to be output, and it indicates the content (e.g., title) using pictures, photographs, or text.

[0036] The processor 100 functions as the occupant detection unit 105, the driving state detection unit 106, and the display control unit 107 by reading and executing the control program 114 stored in the memory 110.

[0037] [1-3. Configuration of the Crew Detection Unit] The occupant detection unit 105 detects the occupant P of the vehicle 1. In this embodiment, the occupant detection unit 105 detects occupants P based on the captured images received from cameras 15, 17, and 18. The occupant detection unit 105 detects a face image for each received captured image using a method such as pattern matching. The occupant detection unit 105 detects occupants P by detecting the face image.

[0038] The crew detection unit 105 calculates facial features for each detected crew member P if it has detected a face image, i.e., if it has detected a crew member P. The facial features are calculated based on, for example, the size of the face image in the captured image, the position of the eye feature points, the position of the nose feature points, the position of the mouth feature points, etc.

[0039] When the occupant detection unit 105 detects an occupant P in the vehicle 1, it detects the seating position of each detected occupant P. For example, if the occupant detection unit 105 detects a face image to the left of the center in the image captured by the camera 15, it detects the seat position of occupant P corresponding to that face image as the driver's seat 10A. Furthermore, for example, if the occupant detection unit 105 detects a face image to the right of the center in the image captured by the camera 15, it detects the seat position of occupant P corresponding to that face image as the passenger seat 10B. Furthermore, for example, if the occupant detection unit 105 detects a face image from the image captured by the camera 17, it detects the seat position of occupant P corresponding to that face image as the rear right seat 10C. Furthermore, for example, if the occupant detection unit 105 detects a face image from the image captured by the camera 18, it detects the seat position of occupant P corresponding to that face image as the rear left seat 10D.

[0040] The crew detection unit 105 detects the state of each detected crew member P at predetermined intervals. In this embodiment, the occupant detection unit 105 detects whether or not the occupant is in a predetermined state where they are not looking at the touch panel 13. Examples of such predetermined states include sleeping or looking at something other than the touch panel 13. The occupant detection unit 105 detects the gaze direction and eye state of the detected occupant P from the images captured by cameras 15, 17, and 18 at predetermined intervals using techniques such as pattern matching. The occupant detection unit 105 then detects that the occupant is in a predetermined state where they are not looking at the touch panel 13 if the gaze direction of the detected occupant P is not directed towards the touch panel 13 for a predetermined period of time or if the eye state of the detected occupant P is closed for a predetermined period of time. The direction of the touch panel 13 is defined for the images captured by each camera, and the occupant detection unit 105 performs the above detection based on whether or not the direction of the occupant P's gaze direction matches the direction of the touch panel 13.

[0041] [1-4. Configuration of the driving state detection unit] The driving state detection unit 106 detects the driving state of vehicle 1. The driving state detection unit 106 detects whether vehicle 1 is in motion or not. For example, the driving state detection unit 106 detects that vehicle 1 is in motion if the shift position sensor 21 detects R (reverse), N (neutral), or D (drive). Also, for example, the driving state detection unit 106 detects that vehicle 1 is not in motion if the shift position sensor 21 detects P (parking).

[0042] [1-5. Configuration of the display control unit] The display control unit 107 displays a recommendation screen G on the touch panel 13, which recommends content available within the vehicle 1. As will be described in detail later, the recommendation screen G displays an icon image IC for each piece of content. One piece of content may be, for example, one song, one movie, one video, or one still image.

[0043] The display control unit 107 displays the first recommendation screen G1 as the recommendation screen G via the touch panel 13, as described later.

[0044] Figure 3 shows an example of the first recommendation screen G1. In Figure 3, the upward direction is indicated by the symbol UP, the downward direction by the symbol DW, the leftward direction by the symbol L, and the rightward direction by the symbol R. These four directions—up, down, left, and right—correspond to the four directions in the state of crew member P when viewing the recommendation screen G.

[0045] The first recommendation screen G1 is a screen that recommends content for all crew members P detected by the crew detection unit 105. In other words, the first recommendation screen G1 is not a screen that recommends content for each individual crew member P detected by the crew detection unit 105.

[0046] The first recommendation screen G1 includes the first content-related information J4 for each content distributor. The first content-related information J4 includes name information J41 and a list display area A1. Name information J41 indicates the name of the content provider. List display area A1 is an area that displays a list of content distributed by the content distributor indicated by name information J41, and displays one icon image IC for each piece of content.

[0047] The list display area A1 shown in Figure 3 is configured to display multiple icon image ICs horizontally in a single row, but the list display area A1 may also be configured to display multiple icon image ICs horizontally in multiple rows. Furthermore, the list display area A1 may be configured to display other icon image ICs that were hidden before a predetermined touch operation (such as a flick or slide operation) is performed within the list display area A1.

[0048] Note that the first recommendation screen G1 shown in Figure 3 is configured to recommend content from three content distribution sources on a single screen. However, the screen configuration of the first recommendation screen G1 is not limited to the configuration shown in Figure 3. For example, the first recommendation screen G1 may consist of multiple screens, with each screen recommending content from one or more content distribution sources. In this example, if a predetermined touch operation (flick or slide operation) is performed in an area other than the list display area A1 on the first recommendation screen G1, the first recommendation screen G1 will switch from the screen recommending content to a screen recommending content from another content distribution source.

[0049] Furthermore, the first recommendation screen G1 shown in Figure 3 illustrates the screen when the first APP 111, the second APP 112, and the third APP 113 are stored in memory 110. In other words, the first recommendation screen G1 shown in Figure 3 illustrates the screen when three application programs for using content are installed in memory 110. If four or more of these application programs are installed in memory 110, the first recommendation screen G1 may be configured to recommend content from four or more content distribution sources on a single screen, as shown in Figure 3. Alternatively, if four or more application programs are installed in memory 110, the first recommendation screen G1 may consist of multiple screens, with one or more content distribution sources recommended on a single screen. In this configuration, if a predetermined touch operation (such as a flick or slide) is performed in an area other than the list display area A1 on the first recommendation screen G1, the first recommendation screen G1 switches from a screen that recommends content to a screen that recommends content from another content distribution source.

[0050] Returning to the explanation of the display control unit 107, we will now describe the case where the display control unit 107 displays the first recommendation screen G1.

[0051] The display control unit 107 determines whether or not preference information J3 corresponding to each occupant P detected by the occupant detection unit 105 is stored in the memory 110. More specifically, in this embodiment, the display control unit 107 acquires facial features from the occupant detection unit 105 for each occupant P, and determines for each occupant P whether there is a record R that contains facial features with a matching rate equal to or greater than a threshold. If the display control unit 107 determines that such record R exists, it determines that preference information J3 corresponding to occupant P is stored, and if it determines that such record R does not exist, it determines that preference information J3 corresponding to occupant P is not stored.

[0052] Then, if the display control unit 107 detects any occupant P among those detected by the occupant detection unit 105, and the memory 110 does not store any preference information J3 for that occupant P, it displays the first recommendation screen G1 via the touch panel 13.

[0053] When displaying the first recommendation screen G1, the display control unit 107 performs the following processing for each content source. In other words, the display control unit 107 selects multiple contents received by the content output unit 104. The selection is made randomly. Next, the display control unit 107 obtains icon image ICs from the content information for all of the selected contents. Then, the display control unit 107 generates first content-related information J4, which includes a list display area A1 in which the obtained icon image ICs are arranged and name information J41, and includes the generated first content-related information J4 in the first recommendation screen G1.

[0054] The display control unit 107 displays the second recommendation screen G2 via the touch panel 13, as described later.

[0055] Figure 4 shows an example of the second recommendation screen G2. In Figure 4, the upward direction is indicated by the symbol UP, the downward direction by the symbol DW, the leftward direction by the symbol L, and the rightward direction by the symbol R. These four directions—up, down, left, and right—correspond to the four directions in the state of crew member P when viewing the recommendation screen G.

[0056] The second recommendation screen G2 is a screen that recommends content to each crew member P detected by the crew detection unit 105 and whose preference information J3 is stored in the memory 110.

[0057] The second recommendation screen G2 includes second content-related information J5 for each crew member P detected by the crew detection unit 105 and whose preference information J3 is stored in the memory 110. The second content-related information J5 includes recommended destination information J51 and a list display area A2. The recommended information J51 indicates the person who recommends the content displayed in the corresponding list display area A2, and includes crew identification information J2. List display area A2 is an area that displays a list of recommended content for a single content distribution destination, and displays one icon image IC for each piece of content.

[0058] The list display area A2 shown in Figure 4 is configured to display multiple icon image ICs horizontally in a single row, but the list display area A2 may also be configured to display multiple icon image ICs horizontally in multiple rows. Furthermore, the list display area A2 may be configured to display other icon image ICs that were hidden before a predetermined touch operation (such as a flick or slide operation) was performed within the list display area A1.

[0059] The second recommendation screen G2 of this embodiment has a screen that displays content for each crew member P for each content distribution destination. In other words, if there are multiple content distribution destinations, the second recommendation screen G2 of this embodiment is composed of multiple screens, and one screen displays content from one content distribution destination. If a predetermined touch operation (flick operation or slide operation) is performed in an area other than the list display area A2 on the second recommendation screen G2, the second recommendation screen G2 switches from the screen that recommends content to a screen that recommends content from another content distribution destination.

[0060] The second recommendation screen G2 displays content based on the content display priority if the occupant detection unit 105 detects multiple occupants P. The content display priority is the priority given to displaying the content. The content display priority is set for each occupant P. The content display priority is set based on the occupant P's seat position and the vehicle 1's driving status.

[0061] If vehicle 1 is not in motion, the content display priority is set as follows: The content display priority for occupant P in the driver's seat 10A is set to be higher than the content display priority for occupant P in the passenger seat 10B. Also, the content display priority for occupant P in the passenger seat 10B is set to be higher than the content display priority for occupant P in the rear seats (at least one of the rear right seat 10C and the rear left seat 10D).

[0062] When vehicle 1 is in motion, the content display priority is set as follows: The content display priority for occupant P in the driver's seat 10A is set to be lower than the content display priority for occupant P in the passenger seat 10B and the rear seats. Also, the content display priority for occupant P in the passenger seat 10B is set to be higher than the content display priority for occupant P in the rear seats.

[0063] The second recommendation screen G2 is a single screen for one content distribution source, and content is displayed higher in the list of crew members P who have a higher priority for viewing the content. Here, displaying higher means displaying it at the top in the vertical direction of the recommendation screen G.

[0064] For example, as shown in Figure 1, if occupants P1, P2, P3, and P4 are detected and vehicle 1 is not in motion, the second recommendation screen G2 will display the content for occupant P1 above the content for the other occupants P, and the content for occupant P2 above the content for occupants P3 and P4, on a single screen for one content delivery destination. In other words, in this example, the second recommendation screen G2 will display the second content-related information J5 for occupant P1 above the second content-related information J5 for the other occupants P, and the second content-related information J5 for occupant P2 above the second content-related information J5 for occupants P3 and P4.

[0065] Furthermore, for example, as shown in Figure 1, if occupants P1, P2, P3, and P4 are detected and vehicle 1 is in motion, the second recommendation screen G2 will display the content for occupant P2 above the content for occupant P3 and the content for occupant P1 below the content for the other occupants P on a single screen related to a particular content delivery destination. In other words, in this example, the second recommendation screen G2 will display the second content-related information J5 for occupant P2 above the second content-related information J5 for occupant P3 and the second content-related information J5 for occupant P1 below the second content-related information J5 for the other occupants P.

[0066] Returning to the explanation of the display control unit 107, we will now describe the case where the display control unit 107 displays the second recommendation screen G2.

[0067] If the memory 110 has stored preference information J3 for all occupants P detected by the occupant detection unit 105, the display control unit 107 displays the second recommendation screen G2 via the touch panel 13. Furthermore, after displaying the first recommendation screen G1, if the occupant P is in a predetermined state where the preference information J3 is not stored in the memory 110 and is not looking at the touch panel 13, the display control unit 107 displays the second recommendation screen G2 via the touch panel 13.

[0068] When displaying the second recommendation screen G2, the display control unit 107 sets the content display priority for each crew member P detected by the crew member detection unit 105 and whose preference information J3 is stored in the memory 110.

[0069] Next, the display control unit 107 sets the display priority of the content, and then, for each crew member P detected by the crew member detection unit 105 and whose preference information J3 is stored in the memory 110, it performs the following processing. Specifically, the display control unit 107 acquires facial features from the crew detection unit 105, identifies records R from the crew DB 115 that contain facial features with a matching rate equal to or greater than a threshold, and reads preference information J3 from the identified crew DB 115. Next, for each content distribution destination, the display control unit 107 refers to the content information received by the content output unit 104, identifies one or more content items that correspond to the genre of content included in the read preference information J3, and decides to display the identified content. Next, for each content distribution source, the display control unit 107 acquires an icon image IC of the content to be displayed from the content information. The display control unit 107 also acquires crew identification information J2 from the identified record R. Finally, for each content distribution destination, the display control unit 107 generates second content-related information J5 using the acquired icon image IC and crew identification information J2.

[0070] The display control unit 107 generates second content-related information J5 for each occupant P detected by the occupant detection unit 105 and whose preference information J3 is stored in the memory 110, and then generates a second recommendation screen G2 in which the second content-related information J5 is arranged according to the set content display priority.

[0071] [1-5. Operation of the vehicle display device] Next, with reference to Figure 5, the operation of the vehicle display device 19 related to content recommendation will be explained. Figure 5 is a flowchart showing the operation of the vehicle display device 19.

[0072] The display control unit 107 determines whether or not to recommend content (step SA1). For example, if crew member P inputs an instruction to display a list of content on the touch panel 13, the display control unit 107 makes a positive determination in step SA1.

[0073] If the display control unit 107 determines that it will not recommend any content (step SA1: NO), it will perform the determination in step SA1 again.

[0074] On the other hand, if the display control unit 107 determines that it is appropriate to recommend content (step SA1: YES), the occupant detection unit 105 detects an occupant P who is in the vehicle 1 (step SA2).

[0075] Next, the driving state detection unit 106 detects the driving state of the vehicle 1 (step SA3). Note that the processing order of steps SA2 and SA3 may be reversed. Also, steps SA2 and SA3 may be executed simultaneously.

[0076] Next, the display control unit 107 determines whether the memory 110 has stored the preference information J3 for all occupants P detected in step SA2 (step SA4).

[0077] If the display control unit 107 determines that the memory 110 does not store the preference information J3 for all occupants P detected in step SA2 (step SA4: NO), it displays the first recommendation screen G1 via the touch panel 13 (step SA5).

[0078] Furthermore, on the first recommendation screen G1, when an icon image IC is selected by touch operation, the content output unit 104 outputs the content corresponding to the selected icon image IC. Specifically, if the content corresponding to the selected icon image IC is content distributed by the first APP 111, the first content output unit 101 outputs the content corresponding to the selected icon image IC. If the content corresponding to the selected icon image IC is content distributed by the second APP 112, the second content output unit 102 outputs the content corresponding to the selected icon image IC. If the content corresponding to the selected icon image IC is content distributed by the third APP 113, the third content output unit 103 outputs the content corresponding to the selected icon image IC.

[0079] On the other hand, if the display control unit 107 determines that the memory 110 has stored the preference information J3 for all occupants P detected in step SA2 (step SA4: YES), it displays the second recommendation screen G2 via the touch panel 13 (step SA6).

[0080] Furthermore, on the second recommendation screen G2, when one icon image IC is selected by touch operation, the content output unit 104 outputs the content corresponding to the selected icon image IC.

[0081] Next, with reference to Figure 6, the operation of the vehicle display device 19 related to content recommendation will be explained. Figure 6 is a flowchart illustrating the operation of the vehicle display device 19. The operation shown in Figure 6 is triggered when the touch panel 13 displays the first recommendation screen G1.

[0082] The display control unit 107 determines whether the state of occupant P, for whom preference information J3 is not stored in memory 110, is in a predetermined state where they are not looking at the touch panel 13 (step SB1). The display control unit 107 makes the determination in step SB1 based on the detection result of the occupant detection unit 105.

[0083] If the display control unit 107 determines that the state of occupant P, for whom preference information J3 is not stored in memory 110, is not in a predetermined state where they are not looking at the touch panel 13 (step SB1: NO), it performs the determination in step SB1 again.

[0084] On the other hand, if the display control unit 107 determines that the state of occupant P, for whom preference information J3 is not stored in memory 110, is a predetermined state in which the occupant is not looking at the touch panel 13 (step SB1: YES), it displays the second recommendation screen G2 on the touch panel 13 (step SB2).

[0085] [2. Second Embodiment] Next, a second embodiment will be described. In the description of the second embodiment, components that are the same as those in the first embodiment are denoted by the same reference numerals, and detailed descriptions are omitted as appropriate.

[0086] Figure 7 shows the configuration of the content distribution system 1000 according to the second embodiment. As is clear from comparing Figure 7 with Figure 1, the vehicle 1 of the second embodiment is equipped with touch panels 22, 23, and 24. Furthermore, as is clear from comparing Figure 7 and Figure 1, the vehicle 1 of the second embodiment is equipped with speakers 25, 26, 27, and 28. Touch panels 22, 23, and 24 are examples of "display units".

[0087] Each of the touch panels 22, 23, and 24 consists of a display panel for displaying characters and images, and a touch sensor for detecting contact with the display panel, superimposed or integrated. Touch panel 22 is installed on the dashboard 12, on the passenger seat 10B side of touch panel 13. Touch panel 23 is installed in a position visible to occupant P seated in the rear right seat 10C, for example, on the back of the driver's seat 10A. Touch panel 24 is installed in a position visible to occupant P seated in the rear left seat 10D, for example, on the back of the passenger seat 10B.

[0088] Speaker 25 outputs sound to occupant P seated in the driver's seat 10A. Speaker 26 outputs sound to occupant P seated in the passenger seat 10B. Speaker 27 outputs sound to occupant P seated in the rear right seat 10C. Speaker 28 outputs sound to occupant P seated in the rear left seat 10D. Note that the installation positions of speakers 25, 26, 27, and 28 are not limited to those shown in Figure 7, but are acceptable as long as they can output sound to occupant P seated in the corresponding seats.

[0089] Figure 8 shows the configuration of the vehicle display device 19 according to the second embodiment. As is clear from comparing Figure 8 and Figure 2, the vehicle display device 19 is connected to touch panels 22, 23, and 24, and speakers 25, 26, 27, and 28. Furthermore, as is clear from comparing Figure 8 and Figure 2, memory 110 stores control program 114A instead of control program 114. Control program 114 is an example of a "program".

[0090] The control program 114A is a program that causes the processor 100 to function as the occupant detection unit 105, the driving state detection unit 106, and the display control unit 107A.

[0091] The display control unit 107A displays the recommendation screen G on each of the touch panels 13, 22, 23, and 24.

[0092] If the display control unit 107A detects a crew member P among those crew members P detected by the crew member detection unit 105, and the memory 110 does not store preference information J3 for that crew member P, it displays the first recommendation screen G1 on each of the touch panels 13, 22, 23, and 24.

[0093] If the memory 110 has stored preference information J3 for all occupants P detected by the occupant detection unit 105, the display control unit 107A displays the second recommendation screen G2 on each of the touch panels 13, 22, 23, and 24. In this case, the display control unit 107A sets a content display priority for each of the touch panels 13, 22, 23, and 24, and displays the second recommendation screen G2 based on the set content display priority.

[0094] More specifically, the display control unit 107A sets the display priority of content for each of the touch panels 13, 22, 23, and 24 to be higher than the display priority of content for other occupants P who are not the target occupant. Then, the display control unit 107A displays the content for each of the touch panels 13, 22, 23, and 24 based on the set content display priority.

[0095] The display control unit 107A sets the display priority of content set for occupant P seated in the driver's seat 10A on the touch panel 13 to be higher than the display priority of content set for occupant P seated elsewhere. As a result, for example, when occupants P1, P2, P3, and P4 are detected as shown in Figure 1, the second recommendation screen G2 displayed on the touch panel 13 will display content for occupant P1 above content for other occupant P, and content for occupant P2 above content for occupant P3 and P4 on a single screen related to a particular content delivery destination.

[0096] The display control unit 107A sets the display priority of the content set for occupant P seated in the passenger seat 10B on the touch panel 22 to be higher than the display priority of the content set for occupant P seated in seats other than the passenger seat 10B. As a result, for example, as shown in Figure 1, when occupants P1, P2, P3, and P4 are detected, on the second recommendation screen G2 displayed by the touch panel 22, the content for occupant P2 is displayed above the content for the other occupant P on a single screen related to a particular content delivery destination, and the content for occupant P1 is displayed above the content for occupant P3 and P4.

[0097] The display control unit 107A sets the display priority of the content set for occupant P3 seated in the rear right seat 10C to be higher than the display priority of the content set for occupant P3 seated in a seat other than the rear right seat 10C for the touch panel 23. As a result, for example, as shown in Figure 1, when occupants P1, P2, P3, and P4 are detected, on the second recommendation screen G2 displayed by the touch panel 23, on a single screen related to a particular content delivery destination, the content for occupant P3 is displayed above the content for other occupants P, the content for occupant P1 is displayed above the content for occupants P2 and P4, and the content for occupant P2 is displayed above the content for occupant P4.

[0098] The display control unit 107A sets the display priority of the content set for occupant P4 seated in the rear left seat 10D on the touch panel 24 higher than the display priority of the content set for occupant P4 seated in a seat other than the rear left seat 10D. As a result, for example, as shown in Figure 1, when occupants P1, P2, P3, and P4 are detected, on the second recommendation screen G2 displayed by the touch panel 24, on a single screen related to a particular content delivery destination, the content for occupant P4 is displayed above the content for other occupants P, the content for occupant P1 is displayed above the content for occupants P2 and P3, and the content for occupant P2 is displayed above the content for occupant P3.

[0099] The display control unit 107A may also set the content display priority for each of the touch panels 13, 22, 23, and 24 as follows: The display control unit 107A may set the display priority of content set for other occupants P whose preference information J3 is similar to that of the target occupant stored in memory 110 to be the second highest after the display priority of content set for the target occupant.

[0100] In this embodiment, preference information J3 similar to the preference information J3 of the target occupant refers to preference information J3 that has the same content type and matches a predetermined number (for example, two or more) of content genres indicated by the preference information J3 of the target occupant.

[0101] For example, as shown in Figure 1, if occupants P1, P2, P3, and P4 are detected, and the preference information J3 of occupant P3 is similar to the preference information J3 of occupant P4, the display control unit 107A sets the display priority of the content set for occupant P3 on the touch panel 24 to be the second highest, after the display priority of the content set for occupant P4. As a result, on the second recommendation screen G2 displayed by the touch panel 24, on a single screen related to a particular content delivery destination, the content for occupant P4 is displayed above the content for the other occupants P, the content for occupant P3 is displayed above the content for occupants P1 and P2, and the content for occupant P1 is displayed above the content for occupant P2.

[0102] Next, the operation of the vehicle display device 19 in this embodiment will be explained with reference to Figure 5. When the vehicle display device 19 performs steps SA1 and SA2, it skips step SA3 and performs step SA4, then step SA5, or step SA6. In step SA6 of this embodiment, the display control unit 107A displays the recommendation screen G on each of the touch panels 13, 22, 23, and 24, as described above.

[0103] Furthermore, the operation of the vehicle display device 19 in this embodiment will be explained with reference to Figure 6. When the vehicle display device 19 starts displaying the first recommendation screen G1, it performs step SB1, and if it makes a positive determination in step SB1, it performs step SB2. In step SB2 of this embodiment, the display control unit 107A displays the recommendation screen G on each of the touch panels 13, 22, 23, and 24, as described above.

[0104] Furthermore, when one icon image IC is selected by touch operation on the recommendation screen G displayed by the touch panel 13, the content output unit 104 outputs content corresponding to the selected icon image IC through at least one of the touch panel 13 and the speaker 25. Furthermore, when one icon image IC is selected by touch operation on the recommendation screen G displayed by the touch panel 22, the content output unit 104 outputs content corresponding to the selected icon image IC via at least one of the touch panel 22 and the speaker 26. Furthermore, when one icon image IC is selected by touch operation on the recommendation screen G displayed by the touch panel 23, the content output unit 104 outputs content corresponding to the selected icon image IC via at least one of the touch panel 23 and the speaker 27. Furthermore, when one icon image IC is selected by touch operation on the recommendation screen G displayed by the touch panel 24, the content output unit 104 outputs content corresponding to the selected icon image IC via at least one of the touch panel 24 and the speaker 28.

[0105] [3. Other Embodiments] The embodiments described above are merely examples and can be modified and applied as needed.

[0106] In the embodiment described above, the case of a four-seater vehicle 1 was illustrated. However, the number of passengers that vehicle 1 can accommodate is not limited to four.

[0107] In the embodiments described above, a four-wheeled vehicle 1 was used as an example, but the number of wheels on the vehicle 1 is not limited to four.

[0108] In the embodiments described above, touch panels 13, 22, 23, and 24 were used as examples of the "display unit," but the "display unit" is not limited to touch panels; it may also be a display that does not have touch operation functionality but can be operated by operation keys or the like.

[0109] In the embodiment described above, the vehicle display device 19 is configured not to include a "display unit," but the vehicle display device 19 may also be configured to include a "display unit."

[0110] In the embodiment described above, the icon image ICs are arranged horizontally on the recommendation screen G2, but the arrangement direction of the icon image ICs is not limited to the horizontal direction and may also be vertical.

[0111] In the embodiment described above, the driving state detection unit 106 detects the driving state of the vehicle 1 based on the detection result of the shift position sensor 21. In other embodiments, the vehicle 1 may be provided with a vehicle speed sensor, and the driving state detection unit 106 may detect the driving state of the vehicle 1 using the vehicle speed sensor.

[0112] In the above-described embodiment, the occupant P is detected from images captured by cameras 15, 17, and 18. In other embodiments, the occupant detection unit 105 may detect the occupant P by a method other than the images captured by cameras 15, 17, and 18. For example, if the vehicle display device 19 is informed of who is boarding at the time of boarding, the occupant detection unit 105 may detect the occupant P based on this input. In another embodiment, if a microphone for collecting the occupant P's voice is provided in the vehicle 1, the occupant detection unit 105 may detect the occupant P based on the number and type of voices collected by the microphone. In yet another embodiment, the detection of the occupant P seated in the driver's seat 10A may be performed using an FOB key.

[0113] In the embodiment described above, the seat position of occupant P is detected from the images captured by cameras 15, 17, and 18. In other embodiments, the occupant detection unit 105 may detect the seat position of occupant P by a method other than the images captured by cameras 15, 17, and 18. For example, if input is given to the vehicle display device 19 indicating who will sit in which seat when boarding, the occupant detection unit 105 may detect occupant P based on this input. In other embodiments, the seat position of occupant P may be detected based on the voice of occupant P and the position of the microphone that picks up occupant P's voice most strongly.

[0114] In the embodiment described above, the state of occupant P is detected from images captured by cameras 15, 17, and 18. In other embodiments, the occupant detection unit 105 may detect the state of occupant P by a method other than images captured by cameras 15, 17, and 18. For example, if the vehicle display device 19 periodically obtains the biological data of occupant P, the occupant detection unit 105 may detect the state of occupant P using the biological data of occupant P.

[0115] In the embodiment described above, the vehicle display device 19 is configured to have three application programs installed for using the content. In other embodiments, the number of such application programs installed in the vehicle display device 19 may be two or fewer, or four or more.

[0116] The processor 100 may consist of multiple processors or a single processor. The processor 100 may also be hardware programmed to implement the functional units described above. In this case, these processors may consist of, for example, an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array).

[0117] Furthermore, the configuration of each part of Vehicle 1 shown in Figure 1 is merely an example, and the specific implementation is not particularly limited. In other words, it is not necessarily required that hardware corresponding to each part be implemented individually; it is certainly possible to configure the system so that a single processor executes a program to realize the functions of each part. Also, in the embodiments described above, some of the functions realized by software may be implemented as hardware, or conversely, some of the functions realized by hardware may be implemented as software.

[0118] Furthermore, the operation steps shown in Figures 5 and 6 are divided according to the main processing content, and the present invention is not limited by the way the processing units are divided or by their names. Depending on the processing content, it may be further divided into more steps. Alternatively, it may be divided so that one step unit includes even more processing. Also, the order of the steps may be rearranged as appropriate, as long as it does not impede the spirit of the present invention.

[0119] Furthermore, when the control method for the vehicle display device 19 described above is implemented using the processor 100, the program to be executed by the processor 100 can be configured as a recording medium or a transmission medium for transmitting this program. In other words, the control program 114 can also be implemented by recording it on a portable information recording medium. Examples of information recording media include magnetic recording media such as hard disks, optical recording media such as CDs, and semiconductor storage devices such as USB (Universal Serial Bus) memory and SSDs (Solid State Drives), but other recording media can also be used.

[0120] [4. Configurations supported by the above embodiments] The above embodiment supports the following configuration.

[0121] (Composition 1) A vehicle display device comprising: a display control unit that recommends content available in the vehicle by displaying said content on a display unit installed inside the vehicle; an occupant detection unit that detects occupants riding in the vehicle; and a storage unit that stores preference information indicating the content preferences of each occupant of the vehicle, wherein the display control unit changes the display mode of the content depending on whether or not the storage unit stores the preference information corresponding to the occupant detected by the occupant detection unit. According to the vehicle display device of configuration 1, the display mode of the content differs depending on whether or not preference information for the detected occupant is stored. Therefore, content can be recommended considering that the vehicle occupants may include occupants whose content preferences are unknown. Thus, content can be appropriately recommended to the occupants of the vehicle.

[0122] (Configuration 2) The vehicle display device according to Configuration 1, wherein the display control unit, when the occupant detection unit detects multiple occupants and the storage unit stores preference information for all occupants detected by the occupant detection unit, displays the content based on the corresponding preference information for each occupant detected by the occupant detection unit. According to the vehicle display device of configuration 2, if the content preferences of all occupants of the vehicle can be understood, content based on preference information can be recommended to each occupant, thus allowing for the recommendation of appropriate content to each occupant.

[0123] (Composition 3) The vehicle display device according to configuration 2, wherein the occupant detection unit detects the seating position of each detected occupant, the display control unit sets a display priority for the content for each occupant detected by the occupant detection unit based on the seating position of the occupant detected by the occupant detection unit, and displays the content based on the set display priority for the content. According to the vehicle display device of configuration 3, content can be recommended considering the occupant's seating position by setting the display priority of content based on the occupant's seating position. Therefore, content can be recommended more appropriately to the occupant of the vehicle.

[0124] (Composition 4) The vehicle display device according to configuration 3, comprising a driving state detection unit for detecting the driving state of the vehicle, wherein the display control unit sets the display priority of the content based on the driving state of the vehicle detected by the driving state detection unit. The occupants most likely to use the content may differ depending on the vehicle's driving conditions. For example, when the driver is at the wheel, the driver is less likely to use the content, while other occupants are more likely to use it. Therefore, the vehicle display device in configuration 4 can recommend content considering the vehicle's driving conditions by setting the display priority of the content based on the vehicle's driving conditions, thus recommending content to occupants who are more likely to use it. In other words, it can recommend content more appropriately to the occupants of the vehicle.

[0125] (Composition 5) The vehicle display device according to configuration 3, wherein the vehicle is equipped with a display unit for each seat, and the display control unit sets the display priority of the content to be set for a target occupant, who is an occupant seated in the corresponding seat, to be higher than the display priority of the content to be set for an occupant other than the target occupant, and displays the content based on the set display priority. When multiple displays are provided for each seat in a vehicle, the occupant using content on a particular display is likely to be the occupant seated in the seat corresponding to that display. Therefore, the vehicle display device in configuration 5 can recommend content to occupants who are likely to use it by prioritizing the display of content preferred by the target occupant. Thus, even when displays are installed for each seat, content can be recommended more appropriately to the occupants of the vehicle.

[0126] (Composition 6) The vehicle display device according to configuration 5, wherein the display control unit sets the display priority of the content to be set for other occupants whose preference information is similar to that of the target occupant and whose preference information is stored in the storage unit to be the second highest display priority of the content to be set for the target occupant. According to the vehicle display device of configuration 6, in addition to content preferred by the target occupant, content preferred by other occupants with similar preferences to the target occupant can be displayed. Therefore, the number of content recommendations can be increased, content that the target occupant is likely to like can be recommended, and the target occupant can understand what kind of content other occupants prefer.

[0127] (Composition 7) The vehicle display device according to any one of configurations 1 to 6, wherein the display control unit displays the content for all occupants detected by the occupant detection unit if the occupant detection unit detects a plurality of occupants and the occupants detected by the occupant detection unit include occupants whose preference information is not stored in the storage unit. According to the vehicle display device of configuration 7, if the vehicle's occupants include passengers whose content preferences are unknown, content can be displayed for all occupants. Therefore, displaying content for a specific passenger will not result in recommending content that passengers with unknown preferences do not like. Thus, even if the vehicle's occupants include passengers whose content preferences are unknown, appropriate content can be recommended to the vehicle's occupants.

[0128] (Composition 8) The vehicle display device according to configuration 7, wherein the display control unit displays the content without being based on the preference information. The vehicle display device of configuration 8 can prevent passengers whose content preferences are unknown from learning what kind of content the passengers prefer. Therefore, even if the vehicle's passengers include passengers whose content preferences are unknown, content can be recommended more appropriately to the passengers.

[0129] (Composition 9) The vehicle display device according to configuration 7 or 8, wherein the occupant detection unit detects the state of the detected occupant, and the display control unit, when the occupant detection unit detects that the state of an occupant for whom the storage unit does not store the preference information is a predetermined state in which the occupant is not looking at the display unit, displays the content based on the corresponding preference information for each occupant detected by the occupant detection unit. According to the vehicle display device of configuration 9, content can be appropriately recommended while taking into account the state of the occupant, whose content preferences are unknown.

[0130] (Composition 10) A control method for a vehicle display device, comprising: storing preference information indicating the preferences of each occupant of the vehicle for content available in the vehicle; detecting occupants in the vehicle; recommending content by displaying it on a display unit installed in the vehicle; and, in displaying the content, differentiating the display mode of the content depending on whether or not the preference information corresponding to the detected occupant is stored. The control method for the vehicle display device of configuration 10 produces the same effect as the vehicle display device of configuration 1.

[0131] (Composition 11) A program for a vehicle display device processor, which includes a storage unit that stores preference information indicating the preferences of each occupant of the vehicle regarding the content available in the vehicle, is configured to function as a display control unit that recommends the content by displaying it on a display unit installed in the vehicle, and an occupant detection unit that detects occupants riding in the vehicle, wherein the display control unit varies the display mode of the content depending on whether or not the storage unit stores the preference information corresponding to the occupant detected by the occupant detection unit. According to the program of configuration 11, it produces the same effect as the vehicle display device of configuration 1. [Explanation of Symbols]
