[0006] Problems to be solved by the invention

[0007] However, when a user in a vehicle views content displayed on a display device in the vehicle, particularly when the user is young and easily distracted by the content, it is desirable to switch the content appropriately to prevent the user from becoming bored with the content from continuously viewing the same content. However, when multiple users are viewing the same content, it is necessary to adjust for differences in preferences among the users, which can lead to time-consuming selection of the next content to be output, potentially delaying the switching of content. Therefore, the present application aims to support rapid switching of the output content when multiple users in a mobile vehicle, such as a vehicle, view the same content output from a content output device used in the mobile vehicle.

[0008] In order to solve the above-mentioned problems, the present application aims to improve operability and further improve traffic safety to contribute to the development of a sustainable transportation system.

[0009] Means for solving problems

[0010] As a first method for achieving the above-mentioned purpose, there can be cited a content output control device, which comprises: a user attribute information acquisition unit, which acquires attribute information of multiple users riding on a mobile body; a common attribute identification unit, which identifies common attributes possessed by multiple users based on the attribute information of the multiple users, namely, common attributes; a first content determination unit, which determines, based on the common attributes, a first content output from a content output device used by the multiple users in the mobile body; a user priority determination unit, which determines the priority among the multiple users; and a second content determination unit, which determines, based on the priority, a second content output from the content output device after the output of the first content from the content output device is completed.

[0011] In the content output control device, the user priority ranking determination unit may determine the priority ranking based on the attribute information of the plurality of users.

[0012] In the above-mentioned content output control device, the user priority ranking determination unit may determine the priority ranking based on results of games executed by a plurality of the users.

[0013] In the above-mentioned content output control device, the second content determination unit may determine the second content based on the attribute information of the user having the highest priority, ie, the priority user.

[0014] In the above-mentioned content output control device, it can also be constructed as: having a content switching restriction unit, which prevents non-priority users from switching the content output from the content output device while the second content is being output from the content output device, wherein the non-priority user is the user other than the priority user, that is, the user with the highest priority.

[0015] In the above-mentioned content output control device, it can also be constructed as follows: multiple 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 when the second content is image content and the second content is being displayed on the display units of multiple content output control devices, the content switching restriction unit allows the users other than the priority user, that is, non-priority users, to output content that only includes sound from the content output device being used by the non-priority user.

[0016] In the above-mentioned content output control device, it can also be constructed as: comprising: a destination identification unit, which identifies the destination of the mobile body; a remaining movement time identification unit, which identifies the remaining movement time of the mobile body to move to the destination; and a content output control unit, which sets the time to output the second content from the content output device based on the remaining movement time.

[0017] In the above-mentioned content output control device, it can also be constructed as follows: the content output control unit adjusts the distribution of content output time in such a way that the output time of the second content in the remaining time of movement is longer than the output time of the content corresponding to the non-priority user in the remaining time of movement, and the non-priority user is the user with the highest priority, that is, the user other than the priority user.

[0018] As a second method for achieving the above-mentioned purpose, a content output control method can be cited, which is a content output control method executed by a computer, wherein the content output control method includes: a user attribute information acquisition step, acquiring attribute information of multiple users riding on a mobile body; a common attribute identification step, identifying common attributes possessed by multiple users, i.e., common attributes, based on the attribute information of multiple users; a first content determination step, determining, based on the common attributes, the first content to be output from a content output device used by multiple users in the mobile body; a user priority determination step, determining the priority among the multiple users; and a second content determination step, determining, based on the priority, the second content to be output from the content output device after the output of the first content from the content output device is completed.

[0019] As a third method for achieving the above-mentioned purpose, there can be cited a recording medium, which records a program that enables a computer to function as the following parts: a user attribute information acquisition unit, which acquires attribute information of multiple users riding on a mobile body; a common attribute identification unit, which identifies common attributes possessed by multiple users based on the attribute information of multiple users; a first content determination unit, which determines the first content to be output from a content output device used by multiple users in the mobile body based on the common attributes; a user priority determination unit, which determines the priority among multiple users; and a second content determination unit, which determines the second content to be output from the content output device based on the priority after the output of the first content from the content output device is completed.

[0020] Effects of the Invention

[0021] The content output control device, content output control method, and recording medium described above support rapid switching of output content when multiple users on a mobile body such as a vehicle view the same content output from a content output device used in the mobile body.

DETAILED DESCRIPTION

[0028] [1. How to use the content output control device]

[0029] Reference Figure 1 The content output control device 1 of this embodiment is used as follows. The content output control device 1 is mounted on a vehicle 100. Figure 1, user U1 is seated in driver's seat 5, user U2 is seated in passenger seat 6, user U3 is seated in left rear seat 7, and user U4 is seated in right rear seat 8. Users U3 and U4 are minors (children, infants). Vehicle 100 corresponds to the mobile object of the present disclosure. Vehicle 100 includes an electronic control unit (ECU) 2 for controlling the operation of vehicle 100 and a navigation device 3 for providing route guidance.

[0030] In this embodiment, vehicle 100 includes a driver's seat speaker 41 for use by user U1 (driver), a passenger seat display 50a and passenger seat speaker 51a for use by user U2, a left rear seat display 50b and left rear seat speaker 51b for use by user U3, and a right rear seat display 50c and right rear seat speaker 51c for use by user U4 as content output devices whose output is controlled by content output control device 1. Furthermore, when the ECU 2 of vehicle 100 controls driving in autonomous driving mode, which controls the driving of vehicle 100 independently of the driver's driving operations, user U1 can continuously view and hear the content displayed on center display 40. Therefore, when vehicle 100 is driving in autonomous driving mode, center display 40 also becomes a content output device subject to content output control by content output control device 1. Content includes content containing both video and audio, content containing only video without audio, and content containing only audio without video.

[0031] The center display 40 , the passenger seat display 50 a , the left rear seat display 50 b , and the right rear seat display 50 c are touch panel displays.

[0032] The content output control device 1 performs wireless communication based on a communication standard such as Bluetooth (a registered trademark) between communication terminal 95 and smartwatch 96 worn by user U1, communication terminal 90a and smartwatch 91a worn by user U2, communication terminal 90b and smartwatch 91b worn by user U3, and communication terminal 90c and smartwatch 91c worn by user U4. Smartwatches 91a to 91c and 96 are wearable devices capable of detecting the wearer's heart rate.

[0033] The content output control device 1 executes content determination processing for each user U1 to U4 to automatically determine the same content to be output from the content output device used based on the attributes of the users U1 to U4 , regardless of the selection operation of the users U1 to U4 .

[0034] [2. Structure of Content Output Control Device]

[0035] Reference Figure 2 The structure of content output control device 1 will be described. Content output control device 1 is a control unit comprising a processor 10, memory 20 (recording medium), communication unit 30, and the like. Processor 10 corresponds to the computer disclosed herein. Content output control device 1 communicates with content server 210, user management server 211, and the like via communication network 200 via communication unit 30.

[0036] Furthermore, the content output control device 1 wirelessly communicates with communication terminals 90a to 90c and 95 and smart watches 91a to 91c and 96 used in the interior 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.

[0037] 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 containing attribute information of users U1 to U4 utilizing the vehicle 100. This attribute information includes age, gender, preferences, and identification information (such as facial recognition data and a unique identification code for the communication terminal being used). The processor 10 corresponds to the computer of the present disclosure.

[0038] The processor 10 functions as a user attribute information acquisition unit 11, a common attribute identification 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 identification unit 17, a remaining travel time identification unit 18, and a content output control unit 19 by reading and executing the program 21.

[0039] The processing performed by the user attribute information acquisition unit 11 corresponds to the user attribute information acquisition step in the content output control method disclosed herein, and the processing performed by the common attribute identification unit 12 corresponds to the common attribute identification step in the content output control method disclosed herein. The processing performed by the first content determination unit 13 corresponds to the first content determination step in the content output control method disclosed herein, and the processing performed by the user priority ranking determination unit 14 corresponds to the user priority ranking determination step in the content output control method disclosed herein. The processing performed by the second content determination unit 15 corresponds to the second content determination step in the content output control method disclosed herein.

[0040] The user attribute information acquisition unit 11 identifies the users U1 to U4 seated in each of the seats 5 to 8 by performing facial recognition based on 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. The user attribute information acquisition unit 11 then acquires attribute information of the identified user from the user attribute data 22.

[0041] Furthermore, users U1 to U4 seated in seats 5 to 8 may be identified using an identification method other than facial recognition. For example, identification codes of communication terminals 90a to 90c and 95 used by users U1 to U4 may be obtained to identify users U1 to U4 seated in seats 5 to 8. Furthermore, if the 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.

[0042] The following description uses as an example a case where a user U3 sitting in the left rear seat 7 and a user U4 sitting in the right rear seat 8 view and listen to the same content via the left rear seat monitor 50b and the left rear seat speaker 51b, and the right rear seat monitor and the right rear seat speaker 51c. The same applies to other combinations of multiple users viewing and listening to the same content.

[0043] The common attribute recognition unit 12 recognizes the common attributes of the user U3 and the user U4. For example, Figure 3 Attribute information of user U3 sitting in the left rear seat 7 and user U4 sitting in the right rear seat 8 is shown as an example. In this case, the common attribute recognition unit 12 recognizes that the user U3 and the user U4 are under 4 years old and have a hobby of liking animals as common attributes of the user U3 and the user U4.

[0044] Based on the common attribute "age 4 and under, likes animals" identified by the common attribute recognition unit for users U3 and U4, the first content determination unit 13 determines, for example, an animal animation for children under 4 years old as the first content. The user priority ranking determination unit 14 determines the priority ranking between users U3 and U4, for example, by performing any of the following first to fifth determination processes.

[0045] First determination process: The user priority ranking determination unit 14 compares the ages of the user U3 and the user U4 identified based on the attribute information of the user U3 and the user U4. Figure 3 As shown, the priority of the younger user U3 is given higher than that of the older user U4.

[0046] Second determination process: The user priority determination unit 14 performs a game between the user U3 and the user U4, and makes the priority of the winner higher than the priority of the loser. As the game, for example, a game that ends in a short time, such as rock-paper-scissors or drawing lots, is proposed.

[0047] The third decision process...The user priority determination unit 14 determines the priority between user U3 and user U4 according to the set priority when the protector has pre-set the priority of user U3 and user U4 because user U3 and user U4 are young (making the priority of younger user U3 higher than that of user U4, etc.).

[0048] Fourth determination processing: When a user is identified as being in motion based on the motion of the user U3 recognized from the image of the user U3 captured by the left rear seat camera 53b, the changes in the user U3's heart rate detected by the smartwatch 91b, the motion of the user U4 recognized from the image of the user U4 captured by the right rear seat camera 53c, and the changes in the user U4's heart rate detected by the smartwatch 91c, the priority of the in motion user is raised. For example, when the user U3 is identified as being in motion, the priority of the user U3 is raised over that of the user U4.

[0049] Fifth Determination Process: When the user priority order determination unit 14 determines the priority order between the user U3 and the user U4, it stores the determined priority order information in the memory 20, etc. Then, when the user U3 and the user U4 are boarding the vehicle 100, the user priority order determination unit 14 refers to the stored priority order information to determine the priority order between the user U3 and the user U4.

[0050] The second content determination unit 15 determines as the second content the content that matches the preference of the higher-priority user U3 (hereinafter referred to as the priority user U3) between the user U3 and the user U4. The content switching restriction unit 16 prevents the lower-priority user U4 (hereinafter referred to as the non-priority user U4) from switching content while the content output control unit 19 is outputting the second content suitable for the priority user U3. Specifically, the content switching restriction unit 16, for example, prevents the content switching operation button from being displayed on the right rear seat display 50c used by the non-priority user U4.

[0051] Alternatively, the content switching restriction unit 16 may be configured to enable switching of content containing only audio for the non-priority user U4. In this case, the non-priority user U4 cannot switch the second content displayed on the right rear seat display 50c, but can switch the audio output from the right rear seat speaker 51c to content containing only audio such as music.

[0052] 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 of the vehicle 100 to the destination. The remaining travel time recognition unit 18 may obtain information on the estimated time required to reach the destination calculated by the navigation device 3 through communication with the navigation device 3 to thereby recognize the remaining travel time, or may calculate the remaining travel time based on the vehicle 100's travel speed, etc., which is assumed to be the distance to the destination.

[0053] 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 performs the following output time allocation process based on the remaining travel time.

[0054] Output Time Allocation Processing: The content output control unit 19 adjusts the time allocation of the content outputted 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.

[0055] In addition, the output time of the second storage information within the remaining movement time may be adjusted according to other conditions.

[0056] [3. Content determination process]

[0057] according to Figure 4 The flowchart shown here illustrates the steps of content determination processing performed by content output control device 1 while vehicle 100 is traveling. The following describes the processing performed when the same content is determined to be viewed by user U3 seated in left rear seat 7 and user U4 seated in right rear seat 8. The same processing also applies when multiple other users view the same content.

[0058] In step S1, as described above, the user attribute information acquisition unit 11 identifies the user U3 sitting in the left rear seat 7 and the user U4 sitting in the right rear seat 8 through facial recognition. In the following step S2, the user attribute information acquisition unit 11 acquires the attribute information of the user U3 and the attribute information of the user U4 recorded in the user attribute data 22, and identifies the attributes of the user U3 and the attribute of the user U4.

[0059] In the next step S3, the common attribute recognition unit 12 recognizes the common attributes of the user U3 and the user U4. Figure 3 In the example of , the common attribute recognition unit 12 recognizes “age is 4 years or younger, and has a hobby of liking animals.” In the next step S4 , the first content determination unit 13 determines the first content based on the common attributes of the user U3 and the user U4 .

[0060] In the next step S5, 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 the right rear seat display 50c and the right rear seat speaker 51c. In the next step S6, when the output of the first content is completed, the content output control unit 19 advances the process to step S7.

[0061] In step S7, the user priority ranking determining unit 14 determines the priority ranking between the user U3 and the user U4. Figure 3 In the example, user U3 is determined as priority user U3 with a high priority, and user U4 is determined as non-priority user U4 with a low priority. In the next step S8, the second content determination unit 15 determines the second content based on the attribute of the priority user U3.

[0062] In the next step S9, the destination recognition unit 17 determines whether a destination has been set via the navigation device 3. If so, the process proceeds to step S20. If not, 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 left rear-seat speaker 51b, and from the right rear-seat display 50c and right rear-seat speaker 51c.

[0063] Furthermore, in step S20, the remaining travel time identification unit 18 identifies the remaining travel time of the vehicle 100 to the destination. 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, as well as the right rear seat display 50c and the right rear seat speaker 51c. In the following step S22, the content output control unit 19 adjusts the distribution 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, as described above.

[0064] Furthermore, while the content output control unit 19 is outputting the second content, the content switching restriction unit 16 prevents the non-priority user U4 from switching the content as described above.

[0065] [4. Other Implementation Methods]

[0066] In the above embodiment, the vehicle 100 is exemplified as the mobile object of the present disclosure. However, the present disclosure is also applicable to other types of mobile objects (such as aircraft and ships) in which a plurality of users (passengers) view and listen to the same content output from a content output device.

[0067] 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 included in the vehicle 100. In another embodiment, the content may be output from the displays and speakers of the communication terminals 90a to 90c, 95 via wireless communication with the communication terminals 90a to 90c, 95.

[0068] While the above embodiment illustrates content output control device 1 included in vehicle 100, the content output control device of the present disclosure may also function as a content server 210 or the like. In this case, authentication information of users riding in vehicle 100 is transmitted from vehicle 100 to content server 210, and content server 210 identifies users U1 to U4 seated in seats 5 to 8 of vehicle 100. Content server 210 then identifies the attributes of users U1 to U4 to determine first and second content, distributes the first and second content to vehicle 100, and outputs the content from a content output device used in vehicle 100.

[0069] Alternatively, the content output control device of the present disclosure can be implemented as a function of an application (app) on communication terminals 90a-90c, 95. In this case, the application uses the communication terminal's built-in camera to capture the user's image and perform facial recognition to identify users U1-U4. Furthermore, the application determines the first and second content based on the attributes of users U1-U4 and outputs them through the display and speaker of the communication terminal. This allows the content output control device of the present disclosure to be implemented by a single communication terminal.

[0070] In the above embodiment, the content switching restriction unit 16 is provided to prohibit non-priority users from switching the content while the second content is being output. Alternatively, the content switching restriction unit 16 may be omitted and the content switching may not be prohibited.

[0071] In the above embodiment, the destination identification unit 17 and the remaining travel time identification unit 18 are provided, and the content output control unit 19 adjusts the distribution of the output time of the second content and the output time of the content corresponding to the non-priority user within the remaining travel time. Alternatively, the destination identification unit 17 and the remaining travel time identification unit 18 may be omitted, and the distribution of the content output time within the remaining travel time may not be adjusted.

[0072] in addition, Figure 2This is a schematic diagram showing the structure of the content output control device 1 according to the main processing contents for easy understanding of the present application. The structure of the content output control device 1 can also be configured by other divisions. In addition, the processing of each component can be performed by one hardware unit or by multiple hardware units. Figure 4 The processing of each component shown may be executed by one program or by a plurality of programs.
