[0003] [Patent Document 1] Patent Publication No. 2021-38954 Summary of the Invention [Problem to be solved by the invention]

[0004] When a user in a vehicle watches content displayed on the vehicle's display device, it is desirable to switch the content appropriately to prevent the user from becoming bored of watching the same content, especially if the user is a child and is being soothed by watching the content. However, when multiple users are watching the same content, it is necessary to adjust for differences in each user's preferences, which can be time-consuming to select the next content to be output, and there is a risk of delays in content switching. Therefore, it is an object of the present application to support rapid switching of output content when multiple users on a moving object such as a vehicle watch the same content output from a content output device used in the moving object. The present invention aims to solve the above problems by improving operability, thereby further improving traffic safety and contributing to the development of a sustainable transportation system. [Means for solving the problem]

[0005] A first aspect for achieving the above object is a content output control device comprising: a user attribute information acquisition unit that acquires attribute information of multiple users on board a mobile body; a common attribute recognition unit that recognizes common attributes that are common attributes shared by multiple users based on the attribute information of the multiple users; a first content determination unit that determines first content to be output from a content output device used by the multiple users on the mobile body based on the common attributes; a user priority determination unit that determines priorities among the multiple users; and a second content determination unit that determines second content to be output from the content output device based on the priorities after output of the first content from the content output device has been completed.

[0006] In the content output control device, the user priority order determination unit may be configured to determine the priority order based on the attribute information of a plurality of the users.

[0007] In the content output control device, the user priority order determination unit may be configured to determine the priority order based on the results of games played by a plurality of the users.

[0008] In the content output control device, the second content determination unit may be configured to determine the second content based on the attribute information of a priority user who is the user with the highest priority order.

[0009] The content output control device may be configured to include a content switching restriction unit that prevents non-priority users other than the priority user, who is the user with the highest priority, from switching the content output from the content output device while the second content is being output from the content output device.

[0010] In the content output control device, a plurality of the content output devices are used in the mobile body, the second content determination unit determines the second content based on the attribute information of the priority user, and the content switching restriction unit may be configured to permit non-priority users other than the priority user to output audio-only content from the content output devices used by the non-priority users when the second content is video content and the second content is displayed on the display units of the plurality of content output control devices.

[0011] The content output control device may be configured to include a destination recognition unit that recognizes the destination of the moving body, a remaining travel time recognition unit that recognizes the remaining travel time of the moving body to the destination, and a content output control unit that sets the time for outputting the second content from the content output device based on the remaining travel time.

[0012] In the content output control device, the content output control unit may be configured to adjust the allocation of content output time so that the output time of the second content during the remaining travel time is longer than the output time of content corresponding to a non-priority user other than the priority user, who is the user with the highest priority during the remaining travel time.

[0013] A second aspect for achieving the above object is a content output control method executed by a computer, the content output control method including: a user attribute information acquisition step for acquiring attribute information of multiple users on board a moving body; a common attribute recognition step for recognizing common attributes that are common attributes possessed by multiple users based on the attribute information of the multiple users; a first content determination step for determining first content to be output from a content output device used by the multiple users on the moving body based on the common attributes; a user priority determination step for determining priorities among the multiple users; and a second content determination step for determining second content to be output from the content output device based on the priorities after output of the first content from the content output device has been completed.

[0014] A third aspect for achieving the above object is a program that causes a computer to function as a user attribute information acquisition unit that acquires attribute information of multiple users on board a mobile body, a common attribute recognition unit that recognizes common attributes that are common attributes shared by multiple users based on the attribute information of the multiple users, a first content determination unit that determines first content to be output from a content output device used by the multiple users on the mobile body based on the common attributes, a user priority determination unit that determines priorities among the multiple users, and a second content determination unit that determines second content to be output from the content output device based on the priorities after output of the first content from the content output device has been completed. [Effects of the Invention]

[0015] The above-mentioned content output control device, content output control method, and program can support quick switching of the content being output when multiple users on board a moving object such as a vehicle are viewing the same content being output from a content output device used on the moving object.

[0017] [1. Usage of content output control device] A usage mode of the content output control device 1 of this embodiment will be described with reference to Fig. 1. The content output control device 1 is mounted on a vehicle 100, and Fig. 1 shows a situation in which a user U1 is seated in the driver's seat 5, a user U2 is seated in the passenger seat 6, a user U3 is seated in the left rear seat 7, and a user U4 is seated in the right rear seat 8. The users U3 and U4 are minors (children, infants). The vehicle 100 corresponds to a moving body in the present disclosure. The vehicle 100 is equipped with an ECU (Electronic Control Unit) 2 that controls the operation of the vehicle 100, and a navigation device 3 that performs route guidance.

[0018] In this embodiment, the vehicle 100 is equipped with the following content output devices for which content output is controlled by the content output control device 1: a driver's seat speaker 41 used by a user U1 (driver), a passenger's seat display 50a and a passenger's seat speaker 51a used by a user U2, a left rear seat display 50b and a left rear seat speaker 51b used by a user U3, and a right rear seat display 50c and a right rear seat speaker 51c used by a user U4. Furthermore, when the ECU 2 provided in the vehicle 100 controls driving in an autonomous driving mode that controls the driving of the vehicle 100 without the driver's driving operation, the user U1 can continuously view content displayed on the center display 40. Therefore, when the vehicle 100 is driving in the autonomous driving mode, the center display 40 also becomes a content output device for which content output is controlled by the content output control device 1. The content includes content including video and sound, content that is only video and does not include sound, and content that is only sound and does not include video.

[0019] The center display 40, the passenger seat display 50a, the left rear seat display 50b, and the right rear seat display 50c are of touch panel specifications.

[0020] The content output control device 1 performs wireless communication using a communication standard such as Bluetooth (registered trademark) among a communication terminal 95 carried by a user U1 and a smart watch 96 worn by the user, a communication terminal 90a carried by a user U2 and a smart watch 91a worn by the user, a communication terminal 90b carried by a user U3 and a smart watch 91b worn by the user, and a communication terminal 90c carried by a user U4 and a smart watch 91c worn by the user. The smart watches 91a to 91c, 96 are wearable devices that have the function of detecting the heart rate of the wearer.

[0021] The content output control device 1 executes a content determination process that automatically determines the same content to be output from the content output device used by each of the users U1 to U4 based on the attributes of the users U1 to U4, without relying on the selection operation of the users U1 to U4.

[0022] [2. Configuration of content output control device] The configuration of the content output control device 1 will be described with reference to Fig. 2. The content output control device 1 is a control unit including a processor 10, a memory 20, a communication unit 30, etc. The processor 10 corresponds to the computer in this disclosure. The content output control device 1 communicates with a content server 210, a user management server 211, etc. via a communication network 200 using the communication unit 30.

[0023] Furthermore, the content output control device 1 performs wireless communication with communication terminals 90a to 90c, 95 and smart watches 91a to 91c, 96 used in the cabin of the vehicle 100 via the communication unit 30. The content output control device 1 is connected to the ECU 2, the navigation device 3, the center display 40, the driver's seat speaker 41, the driver's seat microphone 42, the driver's seat camera 43, the passenger seat display 50a, the passenger seat speaker 51a, the passenger seat microphone 52a, the passenger seat camera 53a, the left rear seat display 50b, the left rear seat speaker 51b, the left rear seat microphone 52b, the left rear seat camera 53b, the right rear seat display 50c, the right rear seat speaker 51c, the right rear seat microphone 52c, and the right rear seat camera 53c.

[0024] The memory 20 of the content output control device 1 stores a program 21 for controlling the content output control device 1 and user attribute data 22 that records attribute information of users U1 to U4 who use the vehicle 100. The attribute information includes age, gender, preferences, identification information (face authentication data, unique identification code of the communication terminal used, etc.), etc. The processor 10 corresponds to the computer of the present disclosure.

[0025] By loading and executing program 21, processor 10 functions as a user attribute information acquisition unit 11, a common attribute recognition unit 12, a first content determination unit 13, a user priority determination unit 14, a second content determination unit 15, a content switching restriction unit 16, a destination recognition unit 17, a remaining travel time recognition unit 18, and a content output control unit 19.

[0026] The processing executed by the user attribute information acquisition unit 11 corresponds to the user attribute information acquisition step in the content output control method of the present disclosure, the processing executed by the common attribute recognition unit 12 corresponds to the common attribute recognition step in the content output control method of the present disclosure, the processing executed by the first content determination unit 13 corresponds to the first content determination step in the content output control method of the present disclosure, the processing executed by the user priority determination unit 14 corresponds to the user priority determination step in the content output control method of the present disclosure, and the processing executed by the second content determination unit 15 corresponds to the second content determination step in the content output control method of the present disclosure.

[0027] The user attribute information acquisition unit 11 identifies the users U1 to U4 seated in the seats 5 to 8 by facial authentication using the facial image data of each user U1 to U4 recorded in the user attribute data 22 and facial image portions extracted from images captured by the driver's seat camera 43, the passenger seat camera 53a, the left rear seat camera 53b, and the right rear seat camera 53c. Then, the user attribute information acquisition unit 11 acquires attribute information of the identified users from the user attribute data 22.

[0028] It should be noted that users U1 to U4 seated at seats 5 to 8 may be identified by an identification method other than facial recognition. For example, users U1 to U4 seated at seats 5 to 8 may be identified by obtaining the identification codes of the communication terminals 90a to 90c, 95 used by users U1 to U4. In addition, if attribute information of users U1 to U4 is stored in the user management server 211, the attribute information may be obtained by accessing the user management server 211 via the communication unit 30.

[0029] The following description will be given taking as an example a case where user U3 seated in the left rear seat 7 and user U4 seated in the right rear seat 8 view the same content using left rear seat display 50b and left rear seat speaker 51b, and right rear seat display and right rear seat speaker 51c. The same applies to other combinations where multiple users view the same content.

[0030] The common attribute recognition unit 12 recognizes the common attributes of the users U3 and U4. For example, Fig. 3 illustrates the attribute information of the user U3 seated in the left rear seat 7 and the user U4 seated in the right rear seat 8. In this case, the common attribute recognition unit 12 recognizes that the common attributes of the users U3 and U4 are that they are aged four or younger and have a preference for animals.

[0031] The first content determination unit 13 determines, for example, an animal animation for children aged 4 or younger as the first content based on the common attributes of users U3 and U4 recognized by the common attribute recognition unit, "age 4 or younger, loves animals." The user priority order determination unit 14 determines the priority between users U3 and U4, for example, by one of the following first to fifth determination processes.

[0032] First determination process: The user priority determination unit 14 compares the ages of user U3 and user U4 recognized from the attribute information of user U3 and user U4, and, as shown in Figure 3, gives the priority of the younger user U3 higher than that of the older user U4. Second determination process: The user priority determination unit 14 makes a game between user U3 and user U4, and gives the winner a higher priority than the loser. As the game, for example, a game that can be completed in a short time, such as rock-paper-scissors or lottery, is suggested. Third determination process: Since users U3 and U4 are young, if the guardian has set the priority of users U3 and U4 in advance (e.g., giving the younger user U3 a higher priority than user U4), the user priority determination unit 14 determines the priority between users U3 and U4 according to the set priority. Fourth determination process: If a user is recognized as being fussy based on the behavior of user U3 recognized from the image of user U3 taken by the left rear seat camera 53b, the change in the heart rate of user U3 detected by the smart watch 91b, the behavior of user U4 recognized from the image of user U4 taken by the right rear seat camera 53c, and the change in the heart rate of user U4 detected by the smart watch 91c, the priority of the fussy user is increased. For example, if it is recognized that user U3 is fussy, the priority of user U3 is increased over user U4. Fifth determination process: When the user priority determination unit 14 determines the priority between user U3 and user U4, it stores information about the determined priority in the memory 20, etc. Then, when user U3 and user U4 subsequently board the vehicle 100, the user priority determination unit 14 refers to the stored priority information and determines the priority between user U3 and user U4.

[0033] The second content determination unit 15 determines, as the second content, content that matches the preferences of user U3 (hereinafter also referred to as priority user U3) who has the higher priority between user U3 and user U4. The content switching restriction unit 16 disables content switching by user U4 (hereinafter referred to as non-priority user U4) who has a lower priority while the content output control unit 19 is outputting the second content that matches the priority user U3. Specifically, the content switching restriction unit 16 does not display an operation button for content switching on, for example, the right rear seat display 50c used by the non-priority user U4.

[0034] The content switching restriction unit 16 may also be configured to allow the non-priority user U4 to switch between sound-only content. In this case, the non-priority user U4 cannot switch the display of the second content on the right rear seat display 50c, but can switch the sound output from the right rear seat speaker 51c to sound-only content such as music.

[0035] The destination recognition unit 17 recognizes the destination of the vehicle 100 set by the navigation device 3 through communication with the navigation device 3. The remaining travel time recognition unit 18 recognizes the remaining travel time to the destination by the vehicle 100. The remaining travel time recognition unit 18 may recognize the remaining travel time by acquiring information on the predicted time required to reach the destination calculated by the navigation device 3 through communication with the navigation device 3, or may calculate the remaining travel time based on the distance to the destination and the estimated travel speed of the vehicle 100, etc.

[0036] The content output control unit 19 controls the output of content from the content output device. When the remaining travel time recognition unit 18 recognizes the remaining travel time, the content output control unit 19 executes the following output time allocation process based on the remaining travel time. Output time allocation process: The content output control unit 19 adjusts the time allocation of the content to be output during the remaining travel time so that the output time of the second content corresponding to the priority user U3 is longer than the output time of the content corresponding to the non-priority user U4. Note that the output time of the second content in the remaining travel time may be adjusted depending on other conditions.

[0037] [3. Content determination process] 4, the procedure of the content determination process executed by the content output control device 1 while the vehicle 100 is traveling will be described. Below, the process executed when determining the same content to be viewed by user U3 seated in the left rear seat 7 and user U4 seated in the right rear seat 8 will be described. The process is similar when multiple other users view the same content.

[0038] In step S1, the user attribute information acquisition unit 11, as described above, uses facial recognition to identify user U3 seated in the left rear seat 7 and user U4 seated in the right rear seat 8. In the following step S2, the user attribute information acquisition unit 11 acquires the attribute information of user U3 and the attribute information of user U4 recorded in the user attribute data 22, and recognizes the attributes of user U3 and user U4.

[0039] In the next step S3, the common attribute recognition unit 12 recognizes the common attributes of user U3 and user U4. In the example of Fig. 3, the common attribute recognition unit 12 recognizes that "the user is four years old or younger and has a preference for animals." In the following step S4, the first content determination unit 13 determines the first content based on the common attributes of user U3 and user U4.

[0040] In the next step S5, content output control unit 19 starts outputting the first content from left rear seat display 50b and left rear seat speaker 51b, and from right rear seat display 50c and right rear seat speaker 51c. In the following step S6, when output of the first content is completed, content output control unit 19 proceeds to step S7.

[0041] In step S7, the user priority determination unit 14 determines the priority between user U3 and user U4. In the example of Fig. 3, user U3 is determined as the priority user U3 with a high priority, and user U4 is determined as the non-priority user U4 with a low priority. In the following step S8, the second content determination unit 15 determines the second content based on the attributes of priority user U3.

[0042] In the following step S9, the destination recognition unit 17 determines whether or not a destination has been set by the navigation device 3, and if a destination has been set, the process proceeds to step S20, or if a destination has not been set, the process proceeds to step S10. In step S10, the content output control unit 19 starts outputting the first content from the left rear seat display 50b and the left rear seat speaker 51b, and from the right rear seat display 50c and the right rear seat speaker 51c.

[0043] Furthermore, in step S20, the remaining travel time recognition unit 18 recognizes the remaining travel time to the destination of the vehicle 100. In the following step S21, the content output control unit 19 starts outputting the first content from the left rear seat display 50b and the left rear seat speaker 51b, and from the right rear seat display 50c and the right rear seat speaker 51c. In the next step S22, as described above, the content output control unit 19 adjusts the allocation of the output time of each content so that the output time of the second content during the remaining travel time is longer than the output time of the content corresponding to the non-priority user U4.

[0044] Furthermore, while the content output control unit 19 is outputting the second content, the content switching restriction unit 16 disables the non-priority user U4 from switching content, as described above.

[0045] 4. Other Embodiments In the above embodiment, a vehicle 100 is used as an example of a moving body of the present disclosure, but the present invention can also be applied to other types of moving bodies (aircraft, ships, etc.) in which multiple users (passengers) watch the same content output from a content output device.

[0046] In the above embodiment, the content output control device 1 outputs content from the displays 50a to 50c, 40 and the speakers 51a to 51c, 41 provided in the vehicle 100. In another embodiment, the content may be output from the display units and speakers of the communication terminals 90a to 90c, 95 through wireless communication with the communication terminals 90a to 90c, 95.

[0047] In the above embodiment, the content output control device 1 provided in the vehicle 100 has been described, but the content output control device of the present disclosure may also be configured as a function of the content server 210, etc. In this case, authentication information of the users riding in the vehicle 100 is transmitted from the vehicle 100 to the content server 210, and the content server 210 identifies the users U1 to U4 seated in seats 5 to 8 of the vehicle 100. The content server 210 then recognizes the attributes of the users U1 to U4, determines the first content and the second content, and distributes the first content and the second content to the vehicle 100, causing them to be output from the content output device used in the vehicle 100.

[0048] The content output control device of the present disclosure may also be configured as a function of an app (application program) of the communication terminals 90a to 90c, 95. In this case, the app identifies users U1 to U4 by photographing the users with the built-in camera of the communication terminal and performing facial recognition. The app then determines the first content and the second content based on the attributes of users U1 to U4 and outputs them from the display unit and speaker of the communication terminal, thereby allowing the communication terminal itself to configure the content output control device of the present disclosure.

[0049] In the above embodiment, the content switching restriction unit 16 is provided to prohibit non-priority users from switching content while the second content is being output. As another configuration, the content switching restriction unit 16 may be omitted, and content switching may not be prohibited.

[0050] In the above embodiment, the destination recognition unit 17 and the remaining travel time recognition unit 18 are provided, and the content output control unit 19 adjusts the output time of the second content during the remaining travel time and the distribution of content output time according to non-priority users. As an alternative configuration, the destination recognition unit 17 and the remaining travel time recognition unit 18 may be omitted, and the distribution adjustment of content output time during the remaining travel time may not be performed.

[0051] 2 is a schematic diagram showing the configuration of the content output control device 1 divided by main processing content to facilitate understanding of the present invention, but the configuration of the content output control device 1 may be divided in other ways. Furthermore, the processing of each component may be executed by one hardware unit or multiple hardware units. Furthermore, the processing of each component shown in FIG. 4 may be executed by one program or multiple programs.
