[0019] The vehicle body 2 further includes a rectangular transparent display 102 between the rear seat 22 and the front seat 21. The transparent display 102 is installed so that the long side of the rectangle is aligned with the horizontal direction (X-axis direction). The transparent display 102 includes at least a self-emissive display 103 and a dimmable film 104 whose light transmittance is variable. The dimmable film may be read as a sheet. In the following explanation, for the sake of clarity, it may be said that the transmittance of the transparent display 102 is changed, but this may be read as changing the transmittance of the dimmable film 104. Examples of the self-emissive display 103 include an organic EL display or an LED display.

[0020] A user sitting in the rear seat 22 can see outside the vehicle through the transparent display 102 and the front windshield 4.

[0021] The transparent display 102 is configured to play predetermined video content. In this embodiment, the video content is described as a moving image, but the video content may also be a still image. Details of the video content will be described later.

[0022] Vehicle 1 comprises a front compartment 23 where front seats 21 are located, and a rear compartment 24 where rear seats 22 are located. Vehicle 1 further comprises a bulkhead 31 that separates the front compartment 23 and the rear compartment 24, and on which a transparent display 102 is located.

[0023] Vehicle 1 is equipped with a light-emitting unit 107 inside the vehicle, whose color and intensity of light can be adjusted.

A portion of the light-emitting unit 107 is shown in Figure 3. An example of the light-emitting unit 107 is an LED (Light Emitting Diode) light.

[0024] Vehicle 1 is equipped with a fragrance generating unit 108 that emits fragrance. The fragrance generating unit 108 is located, for example, in the rear compartment 24. An example of the fragrance generating unit 108 is an aroma diffuser. Details of the fragrance emitted by the fragrance generating unit 108 will be described later.

[0025] Vehicle 1 is equipped with speakers 106 in the rear compartment 24 inside the vehicle. The speakers 106 may be installed above and below the transparent display 102, as shown in Figure 3. In addition, speakers 106 may also be installed in the rear seats 22 (not shown). At least some of the installed speakers 106 (for example, the speakers 106 installed in the rear seats 22) may be tweeters. At least some of the installed speakers 106 may be woofers.

[0026] Vehicle 1 is equipped with an operating unit 109 near the rear seats 22 inside the vehicle. The operating unit 109 may be a tablet terminal installed inside the vehicle. Alternatively, the operating unit 109 may be a smartphone owned by the user connected to Vehicle 1 by wire or wireless connection. Details of the operations that the user can perform through the operating unit 109 will be described later.

[0027] <System Configuration> Figure 4 is a block diagram showing an example configuration of the fatigue recovery support system according to this embodiment.

[0028] The fatigue recovery support system according to this embodiment, mounted on vehicle 1, comprises an ECU 100, an IVI system 101, a transparent display 102, a self-emissive display 103, a dimming film 104, an amplifier 105, a speaker 106, a light-emitting unit 107, a fragrance-generating unit 108, and an operation unit 109. ECU is an abbreviation for Electronic Control Unit. These can transmit and receive information via, for example, a vehicle network 110. Examples of the vehicle network 110 include CAN (Controller Area Network), LIN, or FlexRay.

[0029] The transparent display 102, the self-emissive display 103, the dimming film 104, the speaker 106, the light-emitting unit 107, the fragrance-generating unit 108, and the operating unit 109 have already been explained above, so their explanation will be omitted here.

[0030] Amplifier 105 amplifies the audio signal output from speaker 106. Amplifier 105 may be high-resolution compatible. This allows for higher quality audio output from speaker 106.

[0031] IVI is an abbreviation for "In-Vehicle Infotainment," and Infotainment is a coined word combining Information and Entertainment. The IVI system 101 is a system that provides information and entertainment to passengers using electronic equipment installed in vehicle 1.

[0032] The ECU 100 receives information from the IVI system 101 and sends commands to the IVI system 101 via the vehicle network 110. Note that the number of ECUs 100 installed in vehicle 1 is not limited to one; there may be multiple ECUs 100.

[0033] Furthermore, the ECU 100 may include non-volatile memory. Video content may be stored in the memory. Audio content (hereinafter referred to as audio content) that is output from the speaker 106 in conjunction with the video content may be stored in the memory. Audio content (hereinafter referred to as dimming content) for changing the light transmittance of the dimming film 104 in conjunction with the video content may be stored in the memory. Audio content (hereinafter referred to as light emission content) for illuminating the light emission unit 107 in conjunction with the video content may be stored in the memory. Audio content (hereinafter referred to as fragrance content) for generating fragrance from the fragrance generating unit 108 in conjunction with the video content may be stored in the memory in advance. Furthermore, this content may be updated as appropriate.

[0034] ECU100 processes playback of video content and displays it on the transparent display 102. ECU100 also processes audio content to transmit to amplifier 105 and output audio content from speaker 106 in conjunction with the playback of video content. ECU100 also processes a change in the transmittance of the transparent display 102 based on dimming content in conjunction with the playback of video content. ECU100 also processes a change in the light color and / or light intensity of light-emitting unit 107 based on light-emitting content in conjunction with the playback of video content. ECU100 also processes a change in the scent-generating unit 108 based on fragrance content, including whether or not to generate fragrance, the type of fragrance to be generated, and / or the strength of the fragrance to be generated.

[0035] The ECU 100 receives information indicating the operation content (hereinafter referred to as "operation information") from the operation unit 109 and controls at least one of the transparent display 102, dimming film 104, amplifier 105, light-emitting unit 107, and fragrance generating unit 108 based on the operation information. For example, the ECU 100 controls the transparent display 102 based on the operation information to start or stop playback of video content. For example, the ECU 100 controls the amplifier 105 based on the operation information to adjust the volume of audio content. For example, the ECU 100 controls the dimming film 104 based on the operation information to adjust the maximum and / or minimum values ​​of the transmittance. For example, the ECU 100 controls the light-emitting unit 107 based on the operation information to set whether or not to allow the light-emitting unit 107 to emit light, and to adjust the light intensity. For example, the ECU 100 controls the fragrance generating unit 108 based on the operation information to set whether or not to allow fragrance generation from the fragrance generating unit 108, and to set the fragrance intensity (for example, the strength of the airflow for dispensing the fragrance). Note that the term ECU 100 may be replaced with other terms such as processor, controller, control unit, or control circuit.

[0036] <Processing to support fatigue recovery> Figure 5 is a graph showing examples of changes in the transmittance of the transparent display 102 in each phase according to this embodiment. In the graph shown in Figure 5, the horizontal axis represents time, the vertical axis represents transmittance, and the thick line 201 represents the change in transmittance. Figure 6 is a diagram showing a first example of video content displayed on the transparent display 102 in the first phase according to this embodiment. Figure 7 is a diagram showing a second example of video content displayed on the transparent display 102 in the first phase according to this embodiment. Figure 8 is a diagram showing a first example of video content displayed on the transparent display 102 in the third phase according to this embodiment. Figure 9 is a diagram showing a second example of video content displayed on the transparent display 102 in the third phase according to this embodiment.

[0037] Next, with reference to Figures 5, 6, 7, 8, and 9, we will describe in detail the processes performed to support fatigue recovery for users sitting in the rear seat 22.

[0038] The video content is an image that changes over time and has at least a first phase, a second phase following the first phase, a third phase following the second phase, and a fourth phase following the third phase. In other words, when the video content is played, the video is displayed on the transparent display 102 in the order of the first phase, the second phase, the third phase, and the fourth phase. A light-blocking curtain (not shown) may be provided on the rear door window 5 and closed when the video content is played. Alternatively, a dimmable film with adjustable light transmittance may be provided on the rear door window 5, and the ECU 100 may automatically reduce the transmittance of the dimmable film when playing the video content. This makes it possible to darken the rear compartment 24. Next, each phase will be described in detail.

[0039] <Phase 1> In the first phase, a video designed to promote relaxation for the user (viewer) seated in the rear seat 22 is displayed on the transparent display 102. The transmittance of the transparent display 102 at the end of the first phase (second transmittance) can be smaller than the transmittance of the transparent display 102 at the beginning of the first phase (first transmittance). For example, in the first phase, as shown in Figure 5, the transmittance of the transparent display 102 may change to decrease over time. This allows the user's gaze, which was initially directed at the scenery outside the car through the front windshield 4, to be gradually guided to the video content displayed on the transparent display 102, thereby smoothly directing the user's attention to the video content.

[0040] The video used to promote relaxation in the first half of the first phase may be a video of nature, including forests and rivers, as exemplified in Figure 6 (hereinafter referred to as "nature video 210"). By displaying such nature video 210, the user's tension can be alleviated and they can be encouraged to relax. The video used to promote relaxation in the second half of the first phase may be a video of the setting sun sinking below the horizon or waterline, as exemplified in Figure 7 (hereinafter referred to as "sunset video 220"). By displaying such sunset video 220, the user can be made aware of the end of an active day and they can be encouraged to relax.

[0041] The sunset image 220 may have a horizon or waterline that runs along the longitudinal direction of the rectangular transparent display 102. The sunset image 220 may also include a circular, light-emitting portion (the sunset sun) that is partially touching the horizon or waterline. The sunset image 220 may be configured such that, as viewed by a user sitting in the rear seat 22, the horizon or waterline of the sunset image 220 coincides with or is parallel to the boundary line 300 between the front windshield 4 and the dashboard 7.

[0042] As a result, the view of the outside of the car seen through the front windshield 4 above the boundary line 300 overlaps with the sky above the horizon or waterline in the sunset image 220, and the dashboard 7 below the boundary line 300 overlaps with the ground or sea below the horizon or waterline in the sunset image 220. Typically, the ground or sea below the horizon or waterline in the sunset image 220 is darker than the sky above the horizon or waterline in the sunset image 220, so the dashboard 7 becomes less visible through the transparent display 102. Therefore, the sense of incongruity caused to the user by the overlap between the video content displayed on the transparent display 102 and the view seen through the transparent display 102 can be reduced. In addition, the user's attention, which was focused on the view of the outside of the car seen through the front windshield 4, can be smoothly guided to the video content displayed on the transparent display 102.

[0043] In the first phase, when a natural image 210 is displayed, sound corresponding to the natural image 210 is output from the speaker 106, the light-emitting unit 107 emits light with a color and / or intensity corresponding to the natural image 210, and a fragrance corresponding to the natural image 210 is emitted from the fragrance-generating unit 108. Also in the first phase, when a sunset image 220 is displayed, sound corresponding to the sunset image 220 is output from the speaker 106, the light-emitting unit 107 emits light with a color and / or intensity corresponding to the sunset image 220, and a fragrance corresponding to the sunset image 220 is emitted from the fragrance-generating unit 108. As a result, the user is encouraged to relax not only through sight, but also through hearing and smell.

[0044] <Phase 2> In the second phase, a video designed to induce sleep (i.e., sleep-inducing) is displayed on the transparent display 102 to the user (viewer) sitting in the rear seat 22. The video designed to induce sleep may, for example, be a video with relatively low brightness. Alternatively, in the second phase, video content does not need to be displayed on the transparent display 102.

[0045] The average transmittance of the transparent display 102 during the first phase (first average transmittance) may be greater than the average transmittance of the transparent display 102 during the second phase (second average transmittance). In other words, the average transmittance of the transparent display 102 during the second phase (second average transmittance) may be less than the average transmittance of the transparent display 102 during the first phase (first average transmittance). For example, the transmittance of the transparent display 102 in the second phase may be the minimum value within the range of transmittance that can be set. This makes the inside of the rear chamber 24 relatively dark in the second phase, allowing the user, who was relaxed in the first phase, to be guided into sleep.

[0046] In the second phase, sound corresponding to the sleep-inducing video is output from speaker 106, light-emitting unit 107 emits light with a color and / or intensity corresponding to the sleep-inducing video, and a scent corresponding to the sleep-inducing video is emitted from scent-generating unit 108. Alternatively, in the second phase, sound may not be output from speaker 106, and light-emitting unit 107 may not emit light. This allows the user to be guided to sleep not only through sight, but also through hearing and smell.

[0047] <Phase 3> In the third phase, an image designed to alert the user (viewer) sitting in the rear seat 22 is displayed on the transparent display 102. The transmittance of the transparent display 102 in the third phase may be a third transmittance, which is smaller than the first transmittance. Alternatively, the third transmittance may be equal to the second transmittance. For example, the transmittance of the transparent display 102 in the third phase may be the minimum value within the range of transmittance that can be set.

[0048] The video used to stimulate awakening in the first half of the third phase may be an image of the rising sun (hereinafter referred to as "sunrise video 230"), as exemplified in Figure 8. By displaying such a sunrise video 230, the user can be made aware of the start of an active daytime, thereby stimulating their awakening. The video used to stimulate awakening in the second half of the third phase may be an image including a single flower (hereinafter referred to as "flower video 240"), as exemplified in Figure 9. By displaying such a flower video 240, the user's attention can be attracted, thereby stimulating their awakening.

[0049] The image of the rising sun 230 may have a horizon or horizontal line along the longitudinal direction of the rectangular transparent display 102. The image of the rising sun 230 may also include a circular, light-emitting portion (the rising sun) that is partially touching the horizon or horizontal line. The image of the rising sun 230 may be configured such that, as viewed by a user sitting in the rear seat 22, the horizon or horizontal line of the image of the rising sun 230 coincides with or is parallel to the boundary line 300 between the front windshield 4 and the dashboard 7.

[0050] As a result, the view of the outside of the car seen through the front windshield 4 above the boundary line 300 overlaps with the portion of the sky above the horizon or waterline in the sunrise image 230, and the dashboard 7 below the boundary line 300 overlaps with the portion of the ground or sea below the horizon or waterline in the sunrise image 230. Typically, the portion of the ground or sea below the horizon or waterline in the sunrise image 230 is darker than the portion of the sky above the horizon or waterline in the sunrise image 230, so the dashboard 7 is not very visible through the transparent display 102. Therefore, the sense of incongruity caused to the user by the overlap between the video content displayed on the transparent display 102 and the view seen through the transparent display 102 can be reduced.

[0051] In the third phase, when the image of the sunrise 230 is displayed, sound corresponding to the image of the sunrise 230 is output from the speaker 106, the light-emitting unit 107 emits light with the color and / or intensity corresponding to the image of the sunrise 230, and the fragrance corresponding to the image of the sunrise 230 is emitted from the fragrance-generating unit 108. Also in the third phase, when the image of a flower 240 is displayed, sound corresponding to the image of the flower 240 is output from the speaker 106, the light-emitting unit 107 emits light with the color and / or intensity corresponding to the image of the flower 240, and the fragrance corresponding to the image of the flower 240 is emitted from the fragrance-generating unit 108. As a result, the user is stimulated to become aroused not only through sight, but also through hearing and smell.

[0052] <Phase 4> In the fourth phase, the transparent display 102 displays images that do not induce relaxation, sleep, or wakefulness in the user (viewer) sitting in the rear seat 22. The images displayed in the fourth phase may be, for example, images with relatively high brightness. Alternatively, no video content may be displayed on the transparent display 102 in the fourth phase.

[0053] After a certain period of time has elapsed since the start of the fourth phase, the transmittance of the transparent display 102 may be a fourth transmittance which is greater than the third transmittance. In other words, the fourth transmittance may be a relatively high transmittance. For example, in the fourth phase, as shown in Figure 5, the transmittance of the transparent display 102 may change so that it increases over time. This allows the user's gaze, which was directed at the video content displayed on the transparent display 102, to be gradually guided to the scenery outside the car through the front windshield 4, and the user's attention can be smoothly directed to the scenery outside the car.

[0054] The average transmittance of the transparent display 102 during the fourth phase (third average transmittance) may be greater than the average transmittance of the transparent display 102 during the third phase (fourth average transmittance). For example, the transmittance of the transparent display 102 in the fourth phase may increase over time, as shown in Figure 5, and finally reach the maximum value within the settable range of transmittance. As a result, the transmittance of the transparent display 102 increases, which allows the user's gaze, which was directed towards the video content in the third phase, to be gradually guided through the front windshield 4 to the scenery outside the car, smoothly directing the user's attention to the real scenery outside the car.

[0055] In the fourth phase, sound is not output from the speaker 106, the light-emitting unit 107 does not emit light, and fragrance does not need to be emitted from the fragrance-generating unit 108.

[0056] <About light transmittance> If the rear compartment 24 is made completely dark, making it impossible to see outside the vehicle at all, the user may be more prone to motion sickness. Therefore, the minimum transmittance of the transparent display 102 may be greater than 0. In other words, the transparent display 102 may be configured not to completely block out light from outside the vehicle. The minimum transmittance of the transparent display 102 may be arbitrarily changed. For example, the minimum transmittance of the transparent display 102 when a user prone to motion sickness is sitting in the rear seat 22 may be set higher than the minimum transmittance of the transparent display 102 when a user less prone to motion sickness is sitting in the rear seat 22.
