[0003] [Patent Document 1] Japanese Patent Application Publication No. 2015-89808 Summary of the Invention [Problem to be solved by the invention]

[0004] However, when a user aboard a vehicle views content displayed on a display device of the vehicle, the time for viewing the content is limited to the duration of the ride, so if the content displayed on the display device does not match the user's preferences or mood, it is desirable to quickly switch the displayed content to make the vehicle ride more comfortable. Therefore, an object of the present application is to quickly switch the content output from a content output device used in a mobile object such as a vehicle when the content output from the content output device does not match the preferences or mood of the user aboard the mobile 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]

[0006] In the above content output control device, the output content switching unit may be configured to switch to the second content that outputs only sound without outputting video by the content switching process when the immersion level reduction state recognition unit recognizes that the user is in the immersion level reduction state while the first video content is being output from the content output.

[0007] In the content output control device, the output content switching unit may be configured to switch from the first content to the second content by the content switching process at a timing when output of data of the first content is completed.

[0009] In the above content output control device, the output content switching unit may be configured to output a predetermined response request voice from a user speaker used by the user when the situation in which the immersion level reduction state is recognized by the immersion level reduction state recognition unit continues even after the content switching process is executed, and when a response voice in response to the response request voice is input into a user microphone used by the user, switch the content to be output from the content output device to a third content based on the response voice.

[0010] In the above content output control device, the output content switching unit may be configured to output a predetermined response voice from a driver speaker used by the driver of the mobile body if the response voice is not input to the user microphone within a predetermined time from the time the response request voice is output.

[0011] In the above content output control device, the output content switching unit may be configured to cause a navigation device used in the mobile body to provide route guidance to a stopping location in the vicinity of the mobile body if the response voice is not input into the user microphone within a predetermined time from the time the response request voice is output.

[0012] A second aspect of achieving the above object is a content output control method executed by a computer, the content output control method including: a biometric information acquisition step of acquiring biometric information of a user on a moving body; a reduced immersion state recognition step of recognizing, based on the biometric information, that the user is in a reduced immersion state indicating that the user's level of immersion in content being output from a content output device used on the moving body has decreased; and an output content switching step of executing a content switching process of switching the content output from the content output device to a second content different from the first content when the reduced immersion state recognition step recognizes that the user is in the reduced immersion state while a first content is being output from the content output device.

[Effects of the Invention]

[Figure 3] FIG. 3 is a first flowchart of the output content switching process. [Figure 4] FIG. 4 is a second flowchart of the output content switching process. DETAILED DESCRIPTION OF THE INVENTION

[0016] [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 vehicle 100 corresponds to the mobile body of 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.

[0017] 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.

[0018] 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.

[0019] The content output control device 1 recognizes a decrease in the degree of immersion (degree of interest, concern, etc.) in the content being output from the content output device for each of the users U1 to U4 based on the biometric information, and executes a process of switching the content being output from the content output device. For example, for user U3 sitting in the left rear seat 7, the content output control device 1 acquires, as the biometric information of user U3, an image of user U3 taken by left rear seat camera 53b and the heart rate of user U3 detected by smart watch 91b worn by user U3.

[0020] [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 drive information server 211, etc. via a communication network 200 using the communication unit 30.

[0021] 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.

[0022] A memory 20 of the content output control device 1 stores a program 21 for controlling the content output control device 1. The processor 10 reads and executes the program 21 to function as a biometric information acquisition unit 11, an immersion level reduction state recognition unit 12, and an output content switching unit 13.

[0023] The process executed by the biometric information acquisition unit 11 corresponds to the biometric information acquisition step in the content output control method of the present disclosure, the process executed by the immersion level reduction state recognition unit 12 corresponds to the immersion level reduction state recognition step in the content output control method of the present disclosure, and the process executed by the output content switching unit 13 corresponds to the output content switching step in the content output control method of the present disclosure.

[0024] The biometric information acquisition unit 11 acquires images (particularly facial images) and heart rate detection information of users riding in the vehicle 100 as biometric information of the users. For example, for user U3, the biometric information acquisition unit 11 acquires an image of user U3 taken by the left rear seat camera 53b and heart rate detection information of user U3 detected by the smart watch 91b. The biometric information acquisition unit 11 similarly acquires images and heart rate detection information for the other users U1, U2, and U4.

[0025] The immersion level reduction state recognition unit 12 recognizes that each of the users U1 to U4 is in a state of reduced immersion, which indicates that the level of immersion in the content being output is reduced. For example, the unit 12 recognizes that the level of immersion in the content being output from the left rear seat display 50b and the left rear seat speaker 51b is reduced for the user U3. The same applies to the other users U1, U2, and U3.

[0026] The immersion level reduced state recognition unit 12 recognizes that the user is in a state of reduced immersion level when, for example, any of the following judgment conditions 1 to 3 is recognized from the user's biometric information (image of the user, heart rate of the user). Judgment condition 1: It is recognized from the image of the user that the user's gaze is directed in a direction other than the display (toward the window of the vehicle 100) (the user is not looking at the content displayed on the display). Judgment condition 2: It is recognized that the user has fallen asleep from the image of the user or a decrease in heart rate. Judgment condition 3: From the image of the user or an increase in heart rate, it is recognized that the minor user is fussy.

[0027] The output content switching unit 13 executes a content switching process to switch the content being output for a user who has been recognized as being in a state of reduced immersion by the reduced immersion state recognition unit 12. For example, if user U3 sitting in the left rear seat 7 is recognized as being in a state of reduced immersion, the output content switching unit 13 switches the content being output from the left rear seat display 50b and the left rear seat speaker 51b to other content. The same applies to the other users U1, U2, and U4.

[0028] [3. Output content switching process] The procedure for switching the output content executed by the content output control device 1 will be described with reference to the flowcharts shown in Figures 3 and 4. Figures 3 and 4 show the process for user U3 sitting in the left rear seat 7. The content output control device 1 executes the same process for users U1, U2, and U4 sitting in the other seats.

[0029] In step S1 of FIG. 3, output content switching unit 13 starts outputting the first content from left rear seat display 50b and left rear seat speaker 51b. The first content is content that outputs video and sound. Output content switching unit 13 accesses content server 210 via communication unit 30 to acquire data of the first content. Note that the data of the first content may also be read from a recording medium (such as a magnetic disk, optical disk, or memory card).

[0030] In the next step S2, the biometric information acquisition unit 11 acquires, as biometric information of the user U3, an image of the user U3 taken by the left rear seat camera 53b and detection information of the user U3's heart rate transmitted from the smart watch 91b worn by the user U3. The immersion level reduced state recognition unit 12 recognizes whether the user U3 is in a state of reduced immersion level based on the biometric information of the user U3 and on the above-mentioned judgment conditions 1 to 3.

[0031] In the following step S3, if user U3 is in a state of decreased immersion, the output content switching unit 13 proceeds to step S4, and if user U3 is not in a state of decreased immersion, the output content switching unit 13 proceeds to step S10. In step S10, the output content switching unit 13 determines whether or not the output (playback) of the first content data has finished. Then, if the output of the first content data has finished, the output content switching unit 13 proceeds to step S7, and if the output of the first content data has not finished, the output content switching unit 13 proceeds to step S10.

[0032] In step S4, output content switching unit 13 switches the content to be output from left rear seat display 50b and left rear seat speaker 51b from the first content to the second content. Here, the first content and the second content are different contents, and if the first content is a content containing video and sound, sound-only content may be selected as the second content.

[0033] In the next step S5, the biometric information acquisition unit 11 acquires, as biometric information of the user U3, an image of the user U3 taken by the left rear seat camera 53b and detection information of the user U3's heart rate transmitted from the smart watch 91b worn by the user U3. The immersion level reduced state recognition unit 12 recognizes whether the user U3 is in a state of reduced immersion based on the biometric information of the user U3 and the above-mentioned judgment conditions 1 to 3.

[0034] In the following step S6, if the output content switching unit 13 determines that the user U3 is in a state of reduced immersion, it proceeds to step S20 in Figure 4; if it determines that the user U3 is not in a state of reduced immersion and is immersed in the second content, it proceeds to step S20 in Figure 4.

[0035] 4, the output content switching unit 13 outputs a response request voice, such as "What do you want to do?", from the left rear seat speaker 51b, as illustrated in speech bubble B1, requesting a response from the user U3. In the following step S21, the output content switching unit 13 starts a response waiting timer. By looping the next steps S22 and S30, the output content switching unit 13 keeps inputting the voice of the user U3 into the left rear seat microphone 52 in step S22 until the response waiting timer in step S30 times out.

[0036] When the response voice of user U3 is input to left rear seat microphone 52, output content switching unit 13 proceeds to step S23. In step S23, output content switching unit 13 analyzes the response voice of user U3 to extract the spoken text and selects the third content corresponding to the spoken text. Then, output content switching unit 13 outputs the selected third content from left rear seat display 50b and left component speaker 51b.

[0037] Furthermore, when the response waiting timer times out, the output content switching unit 13 advances the process from step S30 to step S31. In step S31, the output content switching unit 13 outputs a response voice such as "Please check the situation in the left rear seat" from the driver's seat speaker 41, as exemplified by speech bubble B2. This makes it possible to prompt user U1 (the driver) to check the situation of user U3 when it is estimated from the lack of a response that user U3 has fallen asleep or is not feeling well.

[0038] 4. Other Embodiments

[0039] 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 passengers view content output from a content output device.

[0040] In the above embodiment, the output content switching unit 13 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 displays and speakers of the communication terminals 90a to 90c, 95 through wireless communication with the communication terminals 90a to 90c, 95.

[0041] 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 be configured as a function of the content server 210, etc. In this case, biometric information of a user riding in the vehicle 100 is transmitted to the content server 210, and the content server 210 recognizes that the user's immersion level is reduced, and switches the content to be transmitted to the vehicle 100.

[0042] The content output device of the present disclosure may also be configured as a function of an app (application program) of the communication terminals 90a-90c, 95. In this case, the content output device of the present disclosure can be configured by the communication terminal alone by capturing an image of the user using a built-in camera of the communication terminal and outputting content from the display unit and speaker of the communication terminal. Furthermore, by performing communication between the ECU 2 of the vehicle 100 and the communication terminal, the content to be output from the displays 50a-50c, 50 and speakers 51a-51c, 41 provided in the vehicle 100 may be switched by the app of the communication terminal.

[0043] 3, when it is recognized in step S3 that the user's immersion level is low, the content output from the display and speaker is immediately switched from the first content to the second content in step S4. In other embodiments, the timing of switching from the first content to the second content may be set according to the following modifications 1 and 2.

[0044] Variation 1: When it is recognized that the user is in a state of reduced immersion, if the remaining time for outputting the first content is a short time less than a predetermined time, wait until the output of the data of the first content is finished, and switch to the second content at a convenient time when the output of the data of the first content is finished. For example, if the output (playback) of the first content is to finish in three minutes, switch to the second content when the output of the first content has finished after three minutes have passed. Variation 2: If, at the time when it is recognized that the user's level of immersion is decreasing, the remaining time for outputting the data of the first content is longer than a predetermined time, it is assumed that the user does not want to continue watching the first content that he or she has already grown tired of, so the output of the first content is terminated midway and switched to the second content.

[0045] In the above embodiment, when there is no response from the user who is recognized as being in a state of low immersion through the processing of steps S30 to S31 in Fig. 4, a corresponding voice is output to the driver. In another embodiment, when there is no response from the user who is recognized as being in a state of low immersion, route guidance to a place where the vehicle can stop around the current location of the vehicle 100 may be performed by a navigation device provided in the vehicle 100.

[0046] In the above embodiment, an image of the user and heart rate are used as examples of biometric information of the user, but other biometric information may be used. For example, the immersion level reduction state recognition unit 12 may recognize that the user is in a state of reduced immersion level using other types of biometric information such as the user's brain waves, sweating level, body temperature, pulse rate, etc.

[0047] 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 FIGS. 3 and 4 may be executed by one program or multiple programs.
