Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in recent years, development of vehicles that allow users seated in the rear seats to take temporary rest inside the vehicle has been progressing. Therefore, when the voice generation device described in Patent Document 1 is applied to a vehicle so that a user seated in the rear seat who has taken temporary rest can be aroused in a short time, the user needs to gaze at the image displayed on the display. However, the vehicle is not necessarily stopped at the timing to arouse the user, and when the vehicle is traveling on a road, the user may easily get motion sickness due to gazing at the image displayed on the display, which may adversely affect the user's physical condition.

[0005] The present disclosure provides a video control system and the like that can hardly adversely affect the user's physical condition when arousing a user seated in a rear seat who has taken temporary rest inside a vehicle. [Means for solving the problem]

[0006] To achieve the above objective, a video control system according to one embodiment of the present disclosure includes a display provided between the front and rear seats of a vehicle; a first acquisition unit for acquiring driving information relating to the driving status of the vehicle; a second acquisition unit for acquiring information relating to the degree of alertness of a user sitting in the rear seat, ranging from sleep to excitement; and a control unit that, based on the acquired driving information and the acquired information relating to the degree of alertness, identifies one video content from a plurality of video contents and displays the identified one video content on the display, wherein the display is light-transmitting so that the user sitting in the rear seat can see outside the front seat side of the vehicle, and the plurality of video contents include video content for encouraging the user to exercise.

[0007] To achieve the above objective, a video control method according to one embodiment of the present disclosure is a video control method performed by a video control system, the video control system comprising a display provided between the front and rear seats of a vehicle, the video control method comprising: a first acquisition step of acquiring driving information relating to the driving status of the vehicle; a second acquisition step of acquiring information relating to the degree of alertness of a user sitting in the rear seat, ranging from sleep to excitement; and a control step of identifying one video content from a plurality of video contents based on the acquired driving information and the acquired information relating to the degree of alertness, and displaying the identified one video content on the display, the display being light-transmitting so that the user sitting in the rear seat can see outside the front side of the vehicle, and the plurality of video contents including images for prompting the user to exercise. [Effects of the Invention]

[0008] This disclosure provides a video control system, etc., that can minimize adverse effects on the user's physical condition when waking up a user sitting in the rear seat of a vehicle who has taken a temporary rest inside the vehicle. [Brief explanation of the drawing]

[Figure 7] Figure 7 shows an example of a notification displayed on the screen. [Modes for carrying out the invention]

[0010] (Knowledge that forms the basis of this disclosure) First, the inventors' focus is explained below.

[0011] Conventional technologies for promoting human arousal are known. Patent Document 1 discloses a voice generation device that, when the user is in an aroused state, presents a voice prompt suggesting an active action to awaken the user. Furthermore, the voice generation device described in Patent Document 1 discloses that when presenting a voice prompt suggesting an active action to the user, it displays an image representing that active action on a display.

[0012] Incidentally, in recent years, there has been progress in the development of vehicles that allow passengers in the rear seats to take a short rest. Therefore, if the voice generation device described in Patent Document 1 is applied to a vehicle so that passengers in the rear seats can be awakened quickly after taking a short rest, the passenger needs to focus on the image displayed on the screen. However, the vehicle is not always stopped when the passenger needs to be awakened, and if the vehicle is moving on the road, the passenger may become motion sickness due to focusing on the image displayed on the screen, which may negatively affect the passenger's physical condition.

[0013] In light of the above, the inventors have created this disclosure.

[0014] The embodiments of this disclosure will be described in detail below with reference to the drawings. Each embodiment described below is a specific example of this disclosure. The numerical values, components, their arrangement and connection configurations, steps, step order, and display examples shown in the following embodiments are examples only and are not intended to limit this disclosure. Therefore, any components in the following embodiments that are not described in the independent claims of this disclosure will be described as arbitrary components. In each figure, substantially identical components are denoted by the same reference numerals, and redundant explanations may be omitted or simplified.

[0015] In addition, the various elements shown in the drawings are merely schematically illustrated for the understanding of the present disclosure, and dimensional ratios, appearances, and the like may differ from the actual objects. That is, each drawing is a schematic diagram and is not necessarily strictly illustrated. Therefore, for example, the scales and the like in the respective drawings do not necessarily match.

[0016] (Embodiment) [Configuration] First, the configuration of the video control system according to the embodiment will be described with reference to Figure 1. Figure 1 is a block diagram showing the configuration of the video control system 1 according to the embodiment.

[0017] The video control system 1 is a system for displaying video, and is used when watching television, holding a business meeting, providing tourist information, and the like. In addition, the video control system 1 performs fatigue recovery support by displaying video. The fatigue recovery support means that the video control system 1 controls the space inside the vehicle 2 so that a user riding in the vehicle 2 can take a temporary rest.

[0018] Note that when the video control system 1 performs fatigue recovery support, adjustments of sound, light, scent and the like may be performed in addition to video display. In other words, the video control system 1 may control an amplifier 40, a speaker 50, a lighting device 60, and a scent generating device 70 which will be described later, in addition to a display 20 which will be described later. Thereby, the video control system 1 can increase the degree of the user's fatigue recovery. Details of the fatigue recovery support will be described later.

[0019] As shown in Figure 1, the video control system 1 includes a video control device 10, a display 20, a first acquisition unit 31, and a second acquisition unit 32. The video control system 1 is mounted on the vehicle 2.

[0020] The display 20 is, for example, a liquid crystal display or an organic EL (Electro Luminescence) display. Figure 2 is a diagram showing the vehicle 2 and the display 20 mounted on the vehicle 2.

[0021] As shown in Figure 2, the display 20 is installed between the front seat and the rear seat 5 of the vehicle 2. The display 20 is positioned vertically to separate the front seat and the rear seat 5, with the display surface facing the rear seat 5 and the back facing the front seat. The size of the display 20 is, for example, between 40 inches and 60 inches.

[0022] Furthermore, the display 20 has a dimmable film (sheet) with variable light transmittance. Figure 3 shows the display 20 as seen from the rear seat 5 of the vehicle 2.

[0023] As shown in Figure 3, a user sitting in the rear seat 5 can see the front seat 4 through the display 20, and can also see outside the vehicle 2 through the display 20 and the windshield 3. The display 20 has light transmittance that allows the user sitting in the rear seat 5 to see outside on the front seat 4 side of the vehicle 2.

[0024] Furthermore, the display 20 is set to play predetermined video content. In this specification, video content is described as moving images, but it may also be a still image. Also, in this specification, "play video content" may be read as "display video content."

[0025] Returning to the explanation in Figure 1, the video control device 10 is a device that controls the display on the display 20 mounted on the vehicle 2. Figure 1 shows an example where the video control device 10 and the display 20 are different components, but it is not limited to this, and the video control device 10 may be incorporated into the housing of the display 20. Also, the video control device 10 may be composed of part of the ECU (Electronic Control Unit) of the vehicle 2. In addition to controlling the display 20, the video control device 10 may also control the amplifier 40, speaker 50, lighting device 60, and scent generator 70, which will be described later. For example, the video control device 10 may control sound, light, and scent in accordance with the video content played by the display 20.

[0026] The video control device 10 comprises a control unit 11, a sleep time calculation unit 12, and a storage unit 13.

[0027] The control unit 11 is a processing unit that plays (or displays) video content on the display 20. The control unit 11 is implemented by, for example, a microcomputer, but may also be implemented by a processor. The functions of the control unit 11 are realized, for example, by the microcomputer or processor that constitutes the control unit 11 executing a computer program stored in the storage unit 13.

[0028] When the video control system 1 provides fatigue recovery support, the control unit 11 identifies one video content from among multiple video content based on the driving information acquired by the first acquisition unit 31 and the level of alertness acquired by the second acquisition unit 32, and plays (or displays) the identified video content on the display 20. Alternatively, the control unit 11 may identify one video content from among multiple video content by referring to the user's sleep time calculated by the sleep time calculation unit 12.

[0029] The driving information refers to information about the driving status of vehicle 2. Specifically, the driving information includes information on whether vehicle 2 is moving or stopped, as well as information such as the speed, acceleration / deceleration, and direction of vehicle 2. The driving information is obtained, for example, from the parking brake, accelerator pedal, or steering wheel of vehicle 2.

[0030] Furthermore, the level of alertness is an indicator that shows the degree of alertness of the user, from sleep to arousal. The level of alertness is calculated from, for example, eye movement, degree of eyelid opening, degree of mouth opening, pulse rate, or the time it takes to react to external stimuli. The level of alertness is an indicator that shows larger values ​​as the user changes from a sleep state to an aroused state. The level of alertness may be expressed as a continuous numerical value or as discrete numerical values ​​such as level 1, level 2, etc.

[0031] The sleep duration calculation unit 12 is a processing unit that calculates the user's sleep duration based on information about the level of alertness acquired by the second acquisition unit 32. The sleep duration calculation unit 12 calculates the user's sleep duration from fluctuations such as eye movement, eyelid opening, mouth opening, pulse rate, or the time it takes to react to external stimuli. The sleep duration calculation unit 12 is implemented by, for example, a microcomputer, but may also be implemented by a processor. The functions of the sleep duration calculation unit 12 are realized, for example, by the microcomputer or processor constituting the sleep duration calculation unit 12 executing a computer program stored in the memory unit 13.

[0032] The memory unit 13 is a storage device that stores multiple video contents and computer programs executed by the control unit 11 and the sleep time calculation unit 12. The memory unit 13 is implemented, for example, by semiconductor memory.

[0033] The first acquisition unit 31 is a processing unit that acquires the above-mentioned driving information, and is, for example, a communication circuit.

[0034] The second acquisition unit 32 is a processing unit that acquires information regarding the alertness level of a user sitting in the rear seat 5 of the vehicle 2 from a sensor 80, which will be described later, and is, for example, a communication circuit.

[0035] Vehicle 2, as shown in Figure 1, is equipped with a video control system 1, an amplifier 40, a speaker 50, a lighting device 60, a fragrance generator 70, and a sensor 80.

[0036] Vehicle 2 can be, for example, a private car (see Figure 2), a commercial vehicle, a taxi, a truck, or a bus. Furthermore, Vehicle 2 is not limited to having four wheels; it may have two or three wheels, or five or more wheels.

[0037] The amplifier 40 amplifies the signal from the player or other equipment installed in the vehicle 2 and outputs it to the speaker 50.

[0038] Speaker 50 converts the signal output from amplifier 40 into sound and emits the sound into vehicle 2.

[0039] The lighting device 60 is a lighting fixture in which the color and intensity of the light can be adjusted. The lighting device 60 is implemented by, for example, an LED (Light Emitting Diode) element, but may also be implemented by other light-emitting elements such as a semiconductor laser, an organic EL (Electro-Luminescence), or an inorganic EL.

[0040] The fragrance generator 70 is a device that emits fragrance into the vehicle 2. The fragrance generator 70 can be implemented, for example, by an aroma diffuser.

[0041] Sensor 80 is implemented, for example, by a camera. Sensor 80 is installed in a position that can capture images of a user sitting in the rear seat 5 of the vehicle 2. Sensor 80 is installed, for example, around the display 20 shown in Figure 3 (more specifically, on the edge of the display 20). Sensor 80 is also installed in a position that can capture images of the upper body or the entire body of a user sitting in the rear seat 5.

[0042] The sensor 80 may also have an information processing circuit. Specifically, the sensor 80 may calculate the level of alertness by performing image processing on the acquired image using the information processing circuit, and transmit the calculated level of alertness to the second acquisition unit 32 of the video control system 1. The information processing circuit calculates the user's level of alertness based on the acquired image, for example, from eye movement or the degree of eyelid opening.

[0043] Alternatively, the sensor 80 may transmit the acquired image to the second acquisition unit 32 of the video control system 1 as information regarding the level of alertness. In this case, the video control system 1 performs internal image processing based on the acquired image and calculates the level of alertness.

[0044] The above description provides an example of the size of the display 20, but it is not limited to this. For example, the size of the display 20 may be 40 inches or less, or 60 inches or more, depending on the size of the space inside the vehicle 2.

[0045] Furthermore, in the above description, the video content played (or displayed) on the display 20 was described as being stored in the storage unit 13, but this is not limited to this. For example, the video content played (or displayed) on the display 20 may be video content transmitted by a video distribution service, or it may be video content stored on a recording medium such as a DVD (Digital Versatile Disc), BD (Blu-ray® Disc), or hard disk.

[0046] Furthermore, while the above description mentions an example where the sensor 80 is implemented by a camera, it is not limited to this. The sensor 80 may be, for example, a wearable device worn by a user sitting in the rear seat 5. For example, the sensor 80 may measure the user's pulse rate and transmit the measured pulse rate to the second acquisition unit 32 of the video control system 1 as information regarding the user's level of alertness.

[0047] [Regarding support for fatigue recovery] The following describes the overview of fatigue recovery support performed by the video control system 1, with reference to Figure 4. Figure 4 is a flowchart showing the operation of fatigue recovery support performed by the video control system 1 according to the embodiment.

[0048] As shown in Figure 4, the fatigue recovery support in this embodiment includes four phases: the relaxation phase (S1), the sleep phase (S2), the first awakening phase (S3), and the second awakening phase (S4). Next, each phase will be described.

[0049] (1) Relaxation Phase In the relaxation phase, video content designed to promote relaxation is displayed on the display 20 for the user sitting in the rear seat 5. This relaxation content could be, for example, a video showing a forest or a campfire. In the relaxation phase, the video control system 1 can alleviate user tension and promote relaxation by displaying such relaxation content on the display 20. Alternatively, the relaxation content could be, for example, a video showing the sea and a sunset. For instance, in the relaxation phase, the video control system 1 could display video content showing a sunset over the sea on the display 20, making the user aware of the end of an active day and promoting relaxation.

[0050] Furthermore, during the relaxation phase, when relaxing video content is displayed on the display 20, sounds corresponding to the relaxing video content may be emitted from the speaker 50. Similarly, during the relaxation phase, illumination light with a color and intensity corresponding to the relaxing video content may be emitted from the lighting device 60. Similarly, during the relaxation phase, a fragrance corresponding to the relaxing video content may be emitted from the fragrance generator 70. In addition, if a vibration generator is provided in the vehicle 2 to provide vibrations to the user sitting in the rear seat 5, vibrations corresponding to the relaxing video content may be emitted from the vibration generator during the relaxation phase. As a result, the user is encouraged to relax not only through sight, but also through hearing, smell, and touch.

[0051] (2) Sleep Phase During the sleep phase, video content designed to induce sleep is displayed on the display 20 to the user sitting in the rear seat 5. This sleep-inducing video content is, for example, video content with relatively low brightness. During the sleep phase, the video control system 1 can induce sleep in the user by displaying such sleep-inducing video content on the display 20.

[0052] Furthermore, during the sleep phase, when sleep-inducing video content is displayed on the display 20, sounds corresponding to the sleep-inducing video content may be emitted from the speaker 50. Similarly, during the sleep phase, illumination light with a color and intensity corresponding to the sleep-inducing video content may be emitted from the illumination device 60. Similarly, during the sleep phase, a scent corresponding to the sleep-inducing video content may be emitted from the scent generator 70. In addition, if a vibration generator is provided in the vehicle 2 to provide vibrations to the user sitting in the rear seat 5, vibrations corresponding to the sleep-inducing video content may be emitted from the vibration generator during the sleep phase. As a result, sleep is promoted not only through sight, but also through hearing, smell, and touch.

[0053] Furthermore, in this embodiment, the sleep phase lasts approximately 10 minutes. The reason for setting the sleep phase to approximately 10 minutes is that it is said that a person can be refreshed by sleep for about 10 minutes. In experiments conducted by the inventors, the feeling of refreshment that people experience through sleep tended to increase steadily until 10 minutes had passed since the start of sleep, but after 10 minutes, it tended to gradually decrease. Based on these experimental results, the inventors set the sleep phase to approximately 10 minutes. It should be noted that the sleep phase duration shown above is merely an example, and for example, the sleep phase duration may be set to a time of 10 minutes or less, such as approximately 5 minutes, or to a time of 10 minutes or more, such as approximately 15 minutes.

[0054] (3) First Awakening Phase In the first awakening phase, video content designed to stimulate awakening is displayed on the display 20 to the user sitting in the rear seat 5. The awakening video content may include images of animals coming to life in the morning sun in a forest. By displaying such awakening video content on the display 20, the video control system 1 can make the user aware of the start of an active day and stimulate their awakening.

[0055] Furthermore, in the first awakening phase, when video content that promotes awakening is displayed on the display 20, sounds corresponding to the video content that promotes awakening may be emitted from the speaker 50. Similarly, in the first awakening phase, illumination light with a color and intensity corresponding to the video content that promotes awakening may be emitted from the illumination device 60. Similarly, in the first awakening phase, a scent corresponding to the video content that promotes awakening may be emitted from the scent generator 70. In addition, if a vibration generator is provided in the vehicle 2 to provide vibrations to the user sitting in the rear seat 5, vibrations corresponding to the video content that promotes awakening may be emitted from the vibration generator in the first awakening phase. As a result, the user is awakened not only through sight, but also through hearing, smell, and touch.

[0056] (4) Regarding the second awakening phase The inventors found that by adding a second awakening phase to support fatigue recovery, they could further promote user alertness. Specifically, in the second awakening phase, video content encouraging exercise is displayed on the display 20 to the user sitting in the rear seat 5.

[0057] Video content that encourages exercise is, for example, video content that displays the target posture to be achieved during exercise when the user is exercising (see Figure 5A). Figure 5A is a diagram showing the first example of video content. In this specification, video content displayed on the display 20 during the second arousal phase may be referred to as "exercise video content".

[0058] The display 20 displays video content showing the posture the user should aim for when performing exercise (in the example in Figure 5A, the dashed line). The video control system 1 displays such exercise-promoting video content on the display 20, allowing the user to position their body in the desired posture. This promotes alertness not only by simply viewing the video content displayed on the display 20 (i.e., visually), but also by actually moving their body.

[0059] Furthermore, as shown in Figure 5A, the transmittance of the area of ​​the display 20 where video content can be displayed (i.e., the display portion) other than the area where the posture the user should aim for is displayed is greater than the transmittance of the area where the posture is displayed. A user sitting in the rear seat 5 can see the front seat 4 through the display 20 and see outside the vehicle 2 through the display 20 and the windshield 3. This allows the user to exercise while checking the driving status of the vehicle 2, thus reducing the likelihood of motion sickness.

[0060] In the example shown in Figure 5A, the transparency of the area where the user's target posture is displayed is low, and the user cannot see ahead (i.e., outside the front seats 4 and the vehicle 2) in that area. However, this is not the only example. The video control system 1 may change the transparency of that area according to the driving conditions of the vehicle 2 (i.e., driving information). This makes it easier for the user to see the front seats 4 through the display 20, and also to see outside the vehicle 2 through the display 20 and the windshield 3.

[0061] Furthermore, when video content that encourages exercise, as shown in Figure 5A, is displayed on the display 20, instructions such as "Please move your body as shown in the video" may be displayed on the display 20 or conveyed audibly via the speaker 50.

[0062] Furthermore, when video content that encourages exercise, as shown in Figure 5A, is displayed on the display 20, video content such as the sea or a forest may be superimposed on the lower half of the display 20. This allows the user to exercise in a relaxed environment.

[0063] Furthermore, when video content that encourages exercise, as shown in Figure 5A, is displayed on the display 20, sounds corresponding to the video content that encourages exercise may be emitted from the speaker 50. Similarly, illumination light with a color and intensity corresponding to the video content that encourages exercise may be emitted from the lighting device 60. Similarly, a scent corresponding to the video content that encourages exercise may be emitted from the scent generator 70. In addition, if a vibration generator is provided in the vehicle 2 that provides vibration to the user sitting in the rear seat 5, vibrations corresponding to the video content that encourages exercise may be emitted from the vibration generator. As a result, the user is stimulated to become alert not only through sight, but also through hearing, smell, and touch.

[0064] Furthermore, video content that encourages exercise may also be video content that displays the target posture for exercise and the user's current posture when the user is exercising (see Figure 5B). Figure 5B is a diagram showing a second example of video content.

[0065] Display 20 displays video content showing the target posture the user should aim for when performing exercise (dashed line in the example in Figure 5B) and the user's current posture (solid line in the example in Figure 5B). By displaying such exercise-promoting video content on Display 20, the video control system 1 enables the user to recognize the state of their own body and adopt the target posture. This promotes alertness not only by simply viewing the video content displayed on Display 20 (i.e., visually only), but also by actually moving their body.

[0066] Furthermore, as shown in Figure 5B, the transmittance of the area of ​​the display 20 that can display video content (i.e., the display portion) other than the area where the user's target posture and the user's current posture are displayed is greater than the transmittance of the area where the posture is displayed. A user sitting in the rear seat 5 can see the front seat 4 through the display 20 and see outside the vehicle 2 through the display 20 and the windshield 3. This allows the user to exercise while checking the vehicle's driving status, thus reducing the likelihood of motion sickness.

[0067] Furthermore, the video control system 1 may change the transparency of the area where the user's target posture and the user's current posture are displayed, according to the vehicle's driving conditions (i.e., driving information). This makes it easier for the user to see the front seats 4 through the display 20, and also to see outside the vehicle 2 through the display 20 and the windshield 3.

[0068] Furthermore, when video content encouraging exercise, as shown in Figure 5B, is displayed on the display 20, instructions such as "Please move your body as shown in the video" may be displayed on the display 20 or conveyed audibly via the speaker 50.

[0069] Furthermore, when video content encouraging exercise, as shown in Figure 5B, is displayed on the display 20, video content such as the sea or a forest may be superimposed on the lower half of the display 20. This allows the user to exercise in a relaxed environment.

[0070] Furthermore, when video content that encourages exercise, as shown in Figure 5B, is displayed on the display 20, sounds corresponding to the video content that encourages exercise may be emitted from the speaker 50. Similarly, illumination light with a color and intensity corresponding to the video content that encourages exercise may be emitted from the illumination device 60. Similarly, a scent corresponding to the video content that encourages exercise may be emitted from the scent generator 70. In addition, if a vibration generator is provided in the vehicle 2 that provides vibration to the user sitting in the rear seat 5, vibrations corresponding to the video content that encourages exercise may be emitted from the vibration generator. As a result, the user is stimulated to become alert not only through sight, but also through hearing, smell, and touch.

[0071] Furthermore, video content that encourages exercise may also be video content that displays a target as the goal of the exercise when the user is exercising (see Figure 5C). Figure 5C is a diagram showing a third example of video content.

[0072] The display 20 displays video content showing a target (an apple in the example in Figure 5C) that serves as the goal for the exercise when the user is performing the exercise. The video control system 1 displays such exercise-enhancing video content on the display 20, allowing the user to perform the appropriate exercise simply by moving their body towards the target. This stimulates the user's arousal not just by simply watching the video content displayed on the display 20 (i.e., only visually), but also by actually moving their body.

[0073] Furthermore, in the example shown in Figure 5C, the user's current posture (solid line) is displayed on the display 20. The user can exercise while recognizing their own body state and confirming whether they are moving their body toward the target. This allows the video control system 1 to more effectively stimulate the user's alertness.

[0074] Furthermore, as shown in Figure 5C, within the area of ​​the display 20 where video content can be displayed (i.e., the display portion), the transmittance of areas other than those where the target and other images (e.g., an apple tree) and the user's current posture are displayed is greater than the transmittance of the area where the posture is displayed. The user sitting in the rear seat 5 can see the front seat 4 through the display 20 and see outside the vehicle 2 through the display 20 and the windshield 3. This allows the user to exercise while checking the vehicle's driving status, thus reducing the likelihood of motion sickness.

[0075] Furthermore, the video control system 1 may change the transparency of the area where the target image, images other than the target (for example, an apple tree), and the user's current posture are displayed, according to the driving conditions of the vehicle 2 (i.e., driving information). This makes it easier for the user to see the front seats 4 through the display 20, and to see outside the vehicle 2 through the display 20 and the windshield 3.

[0076] Furthermore, when video content encouraging movement, as shown in Figure 5C, is displayed on the display 20, instructions such as "Move your body to touch the apple at the top" may be displayed on the display 20 or conveyed audibly via the speaker 50.

[0077] Furthermore, when video content that encourages exercise, as shown in Figure 5C, is displayed on the display 20, the transparency of the video content may be lower than that of other images (e.g., apple trees) or a mark (e.g., a circle) may be placed on the target to make it easier for the user to recognize the location of the target.

[0078] Furthermore, when video content that encourages exercise, as shown in Figure 5C, is displayed on the display 20, sounds corresponding to the video content that encourages exercise may be emitted from the speaker 50. Similarly, illumination light of a color and intensity corresponding to the video content that encourages exercise may be emitted from the illumination device 60. Similarly, a scent corresponding to the video content that encourages exercise may be emitted from the scent generator 70. In addition, if a vibration generator is provided in the vehicle 2 to provide vibrations to the user sitting in the rear seat 5, vibrations corresponding to the video content that encourages exercise may be emitted from the vibration generator. As a result, the user is stimulated to become alert not only through sight, but also through hearing, smell, and touch.

[0079] Furthermore, video content that encourages exercise may also be video content that utilizes targets that exist in the running environment and serve as goals for the user when they exercise (see Figure 5D). Figure 5D shows a fourth example of video content. The targets may be, for example, the lights of traffic lights on the road (the hatched area in the example of Figure 5D), signs, etc.

[0080] The display 20 displays video content that shows a target that is the goal of the exercise when the user is exercising, and that is present in the running environment (for example, a road) (in the example of Figure 5D, a traffic light). The video control system 1 displays such exercise-enhancing video content on the display 20, so that the user can perform the appropriate exercise simply by moving their body toward the target. In this way, the user is stimulated not only by simply looking at the video content displayed on the display 20 (i.e., only visually), but also by actually moving their body.

[0081] Furthermore, in the example shown in Figure 5D, the user's current posture (solid line) is displayed on the display 20. The user can exercise while recognizing their own body state and confirming whether they are moving their body toward the target. This allows the video control system 1 to more effectively stimulate the user's alertness.

[0082] Furthermore, as shown in Figure 5D, the transmittance of the area of ​​the display 20 that can display video content (i.e., the display portion) other than the area where the user's current posture is displayed is greater than the transmittance of the area where the posture is displayed. A user sitting in the rear seat 5 can see the front seat 4 through the display 20 and see outside the vehicle 2 through the display 20 and the windshield 3. This allows the user to exercise while checking the driving status of the vehicle 2, thus reducing the likelihood of motion sickness.

[0083] Furthermore, the video control system 1 may change the transparency of the area where the user's current posture is displayed, according to the driving conditions of the vehicle 2 (i.e., driving information). This makes it easier for the user to see the front seats 4 through the display 20, and also to see outside the vehicle 2 through the display 20 and the windshield 3.

[0084] Furthermore, when video content that encourages movement, as shown in Figure 5D, is displayed on the display 20, instructions such as "Move your body to touch the traffic light" may be displayed on the display 20 or conveyed audibly via the speaker 50.

[0085] Furthermore, when video content that encourages exercise, as shown in Figure 5D, is displayed on the display 20, marks (e.g., circles) may be placed on the targets to make it easier for the user to recognize their location.

[0086] Furthermore, when video content that encourages exercise, as shown in Figure 5D, is displayed on the display 20, sounds corresponding to the video content that encourages exercise may be emitted from the speaker 50. Similarly, illumination light of a color and intensity corresponding to the video content that encourages exercise may be emitted from the lighting device 60. Similarly, a scent corresponding to the video content that encourages exercise may be emitted from the scent generator 70. In addition, if a vibration generator is provided in the vehicle 2 that provides vibration to the user sitting in the rear seat 5, vibrations corresponding to the video content that encourages exercise may be emitted from the vibration generator. As a result, the user is stimulated to become alert not only through sight, but also through hearing, smell, and touch.

[0087] [Examples of video content that encourages exercise] The following describes variations of video content designed to encourage exercise.

[0088] Video content that encourages exercise may include multiple exercise videos with different intensity levels of exercise encouraged for the user. For example, video content that encourages exercise may include exercise videos that show a first level of exercise intensity and exercise videos that show a second level of exercise intensity, which is higher than the first level. Compared to exercise videos that show a first level of exercise intensity, the exercise videos that show a second level of exercise intensity may, for example, have a different target posture for the user, or a different distance between the user sitting in the back seat 5 and the target.

[0089] While the example given illustrates how exercise intensity in video content can be categorized into two levels, it is also acceptable to categorize it into three or more levels.

[0090] [Operation] The operation of the video control system 1 according to the embodiment will be described below with reference to Figure 6. Figure 6 is a flowchart showing the operations performed by the video control system 1 according to the embodiment during the second awakening phase shown in Figure 4.

[0091] First, the first acquisition unit 31 acquires driving information (S101). The second acquisition unit 32 acquires information regarding the alertness level of the user sitting in the rear seat 5 from the sensor 80 (S102).

[0092] The sleep time calculation unit 12 calculates the sleep time of the user sitting in the rear seat 5 based on the information on the level of alertness obtained in step S102 (S103).

[0093] The control unit 11 determines whether or not the vehicle 2 is in motion based on the driving information acquired in step S101 (S104).

[0094] If the control unit 11 determines that vehicle 2 is in motion (Yes in S104), it determines whether it is dangerous to have the user exercise based on the driving information acquired in step S101 (S105). The timing at which it is dangerous to have the user exercise is, for example, when sudden acceleration or braking of vehicle 2, or sharp turns are detected.

[0095] If the control unit 11 determines that it is dangerous to have the user exercise (Yes in S105), it interrupts the exercise during the second arousal phase (S106). In other words, the control unit 11 does not display any video content encouraging exercise on the display 20. At this time, the control unit 11 may display a notification on the display 20 indicating that the exercise has been interrupted. Figure 7 shows an example of a notification displayed on the display 20.

[0096] Returning to the explanation in Figure 6, if the control unit 11 determines that it is not dangerous to have the user exercise (No in S105), it determines whether the user is awake or not based on the information on the level of alertness obtained in step S102 (S107).

[0097] If the control unit 11 determines that the user is not awake (No in step S107), it identifies an exercise video content that indicates an exercise intensity of level 2 (S108). Then, the control unit 11 displays the exercise video content identified in step S108 on the display 20 (S109).

[0098] On the other hand, if the control unit 11 determines that the user is awake (Yes in step S107), it determines whether the sleep time calculated in step S103 is greater than or equal to a predetermined threshold (S110). The predetermined threshold is, for example, 10 minutes.

[0099] If the control unit 11 determines that the sleep time calculated in step S103 is less than a predetermined threshold (No in step S110), it proceeds to step S108.

[0100] On the other hand, if the control unit 11 determines that the sleep time calculated in step S103 is above a predetermined threshold (Yes in step S110), it identifies a video content for exercise that indicates a first level of exercise intensity (S111). Then, the control unit 11 displays the video content for exercise identified in step S111 on the display 20 (S112).

[0101] On the other hand, if the control unit 11 determines that the vehicle 2 is not in motion (No in step S104), it determines whether the user is awake or not based on the information on the level of alertness obtained in step S102 (S113).

[0102] If the control unit 11 determines that the user is not awake (No in step S113), it identifies a video content for exercise that indicates the second level of exercise intensity (S114). Then, the control unit 11 displays the video content for exercise identified in step S114 on the display 20 (S115).

[0103] In step S115, the transmittance of the display 20 may be the same as the transmittance of the display 20 in step S109 or step S112, or it may be the minimum value within the settable range. In other words, in step S115, the transmittance of the display 20 may be such that a user sitting in the rear seat 5 can see the front seat 4 through the display 20 and see the outside of the vehicle 2 through the display 20 and the windshield 3, or the transmittance of the display 20 may be such that a user sitting in the rear seat 5 cannot see the front seat 4 through the display 20, or cannot see the outside of the vehicle 2 through the display 20 and the windshield 3.

[0104] On the other hand, if the control unit 11 determines that the user is awake (Yes in step S113), it determines whether the sleep time calculated in step S103 is above a predetermined threshold (S116).

[0105] If the control unit 11 determines that the sleep time calculated in step S103 is less than a predetermined threshold (No in step S116), it proceeds to step S114.

[0106] On the other hand, if the control unit 11 determines that the sleep time calculated in step S103 is above a predetermined threshold (Yes in step S116), it identifies a video content for exercise that indicates a first level of exercise intensity (S117). Then, the control unit 11 displays the video content for exercise identified in step S117 on the display 20 (S118).

[0107] In step S118, the transmittance of the display 20 may be the same as the transmittance of the display 20 in step S109 or step S112, or it may be the minimum value within the settable range. In other words, in step S118, the transmittance of the display 20 may be such that a user sitting in the rear seat 5 can see the front seat 4 through the display 20 and see the outside of the vehicle 2 through the display 20 and the windshield 3, or the transmittance of the display 20 may be such that a user sitting in the rear seat 5 cannot see the front seat 4 through the display 20, or cannot see the outside of the vehicle 2 through the display 20 and the windshield 3.

[0108] The video control system 1 has a display 20 that is light-transmitting, allowing the user sitting in the rear seat 5 to see outside the front seat 4 side of the vehicle 2. As a result, the user can understand the vehicle's driving conditions when exercising according to the display 20. This makes it less likely for the user to get carsick even when exercising according to the display 20.

[0109] Furthermore, when the video control system 1 awakens a user sitting in the rear seat 5 who has taken a temporary rest inside the vehicle 2, it can display exercise video content on the display 20 according to the user's level of alertness. This allows the video control system 1 to more effectively encourage the user to become alert.

[0110] Furthermore, the video control system 1 also takes into account the user's sleep duration and selects a single video content from among multiple video content, thereby more effectively stimulating the user to wake up. More specifically, when stimulating a user sitting in the rear seat 5 who has taken a temporary rest in the vehicle 2, the video control system 1 can display exercise video content on the display 20 that is appropriate for the calculated length of the user's sleep duration. This allows the video control system 1 to more effectively stimulate the user to wake up.

[0111] Furthermore, the video control system 1 can wake up a user sitting in the rear seat 5 who has taken a temporary rest inside the vehicle 2, while ensuring the user's safety.

[0112] [Effects, etc.] The effects of the video control system 1, etc., according to this embodiment will be described below.

[0113] The video control system 1 according to this embodiment includes a display 20 provided between the front seat 4 and rear seat 5 of a vehicle 2, a first acquisition unit 31 that acquires driving information relating to the driving status of the vehicle 2, a second acquisition unit 32 that acquires information relating to the degree of alertness of a user sitting in the rear seat 5, ranging from sleep to excitement, and a control unit 11 that identifies one video content from a plurality of video contents based on the acquired driving information and the acquired information relating to the degree of alertness, and displays the identified video content on the display 20. The display 20 is light-transmitting so that a user sitting in the rear seat 5 can see outside on the front seat 4 side of the vehicle 2, and the plurality of video contents include video content that encourages the user to exercise.

[0114] In this video control system 1, the display 20 has light transmittance so that the user sitting in the rear seat 5 can see outside on the front seat 4 side of the vehicle 2. As a result, the user can understand the driving conditions of the vehicle 2 when exercising according to the display 20. This makes it less likely for the user to get carsick even when exercising according to the display 20. Therefore, when waking up a user sitting in the rear seat 5 who has taken a temporary rest inside the vehicle 2, the video control system 1 is less likely to adversely affect the user's physical condition.

[0115] Furthermore, in the video control system 1 according to this embodiment, the control unit 11 changes the transparency of a video content displayed on the display 20 based on the acquired driving information.

[0116] This video control system 1 makes it easier for the user to understand the driving status of the vehicle 2 in accordance with the driving information acquired by the first acquisition unit 31. As a result, when the video control system 1 wakes up a user sitting in the rear seat 5 who has taken a temporary rest inside the vehicle 2, it is less likely to have an adverse effect on the user's physical condition.

[0117] Furthermore, in the video control system 1 according to this embodiment, the video content for prompting the user to exercise includes multiple exercise video contents with different exercise intensities. When the control unit 11 determines that the user is awake based on the acquired information on the level of alertness, it identifies one exercise video content from the multiple exercise video contents that shows an exercise intensity of a first level and displays the identified exercise video content on the display 20. When the control unit 11 determines that the user is not awake based on the acquired information on the level of alertness, it identifies one exercise video content from the multiple exercise video contents that shows an exercise intensity of a second level, which is higher than the first level, and displays the identified exercise video content on the display 20.

[0118] This video control system 1 can display exercise video content on the display 20 according to the user's level of alertness when waking up a user sitting in the rear seat 5 who has taken a temporary rest inside the vehicle 2. This allows the video control system 1 to more effectively encourage the user to become alert.

[0119] Furthermore, the video control system 1 according to this embodiment is further equipped with a sleep time calculation unit 12 that calculates the user's sleep time based on acquired information on the level of alertness, and the control unit 11 identifies one video content from a plurality of video contents based on acquired driving information, acquired information on the level of alertness, and the calculated user's sleep time, and displays the identified video content on the display 20.

[0120] This video control system 1 further takes into account the user's sleep time and identifies one video content from among multiple video content, thereby more effectively stimulating the user to wake up.

[0121] Furthermore, in the video control system 1 according to this embodiment, the video content for prompting the user to exercise includes a plurality of exercise video contents with different exercise intensities. When the control unit 11 determines that the calculated user's sleep time is above a predetermined threshold, it identifies one exercise video content from the plurality of exercise video contents that shows an exercise intensity of a first level and displays the identified exercise video content on the display 20. When the control unit 11 determines that the calculated user's sleep time is below a predetermined threshold, it identifies one exercise video content from the plurality of exercise video contents that shows an exercise intensity of a second level, which is higher than the first level, and displays the identified exercise video content on the display 20.

[0122] This video control system 1 can display exercise video content on the display 20 that is appropriate to the length of the user's sleep, calculated when waking up a user sitting in the rear seat 5 who has taken a temporary rest inside the vehicle 2. This allows the video control system 1 to more effectively encourage the user to wake up.

[0123] Furthermore, in the video control system 1 according to this embodiment, the plurality of video contents include video content that displays the target posture to be achieved during exercise when the user is exercising.

[0124] This video control system 1 displays video content on the display 20 that shows the target posture during exercise. By checking the video content displayed on the display 20, the user can adjust their body to the target posture. This allows the video control system 1 to more effectively stimulate the user's alertness.

[0125] Furthermore, in the video control system 1 according to this embodiment, the plurality of video contents include video contents that display the target posture to be achieved during exercise and the user's current posture when the user is exercising.

[0126] This video control system 1 displays video content on the display 20 that shows the target posture for exercise and the user's current posture. By checking the video content displayed on the display 20, the user can recognize the state of their own body and adopt the target posture. As a result, the video control system 1 can more effectively promote alertness in the user.

[0127] Furthermore, in the video control system 1 according to this embodiment, the plurality of video contents include video content that displays a target that serves as the goal during exercise when the user is performing exercise.

[0128] This video control system 1 displays video content on the display 20 that shows the target to be targeted during exercise, so the user can perform the appropriate exercise simply by moving their body toward the target. As a result, the video control system 1 can more effectively stimulate the user's alertness.

[0129] Furthermore, in the video control system 1 according to this embodiment, the control unit 11 determines whether or not it is dangerous to have the user exercise based on the acquired running information. If it determines that it is not dangerous to have the user exercise, it continues to display a video content on the display 20. If it determines that it is dangerous to have the user exercise, it interrupts the display of the video content on the display 20.

[0130] Such a video control system 1 can wake up a user sitting in the rear seat 5 who has taken a temporary rest inside the vehicle 2, while ensuring the user's safety.

[0131] Furthermore, the video control method according to this embodiment is a video control method executed by a video control system 1, the video control system 1 includes a display 20 provided between the front seat 4 and rear seat 5 of a vehicle 2, and the video control method includes a first acquisition step (S101) of acquiring driving information relating to the driving status of the vehicle 2, a second acquisition step (S102) of acquiring information relating to the degree of alertness of a user sitting in the rear seat 5, ranging from sleep to excitement, and control steps (S104~S118) of identifying one video content from a plurality of video contents based on the acquired driving information and the acquired information relating to the degree of alertness, and displaying the identified one video content on the display 20, the display 20 being light-transmitting so that a user sitting in the rear seat 5 can see outside on the front seat 4 side of the vehicle 2, and the plurality of video contents include videos that encourage the user to exercise.

[0132] This video control method has a light-transmitting display 20 that allows the user sitting in the rear seat 5 to see outside the front seat 4 side of the vehicle 2. As a result, the user can understand the vehicle's driving conditions while exercising according to the display 20. This video control method makes it less likely for the user to get carsick even when exercising according to the display 20. Therefore, the video control method is less likely to adversely affect the user's physical condition when waking up a user sitting in the rear seat 5 who has taken a temporary rest inside the vehicle 2.
