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

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

[0028] The fatigue recovery support system according to the present embodiment mounted on the vehicle 1 includes an ECU 100, an IVI system 101, a transparent display 102, a self-luminous display 103, a dimming film 104, an amplifier 105, a speaker 106, a light emitting unit 107, an aroma 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-luminous display 103, the dimming film 104, the speaker 106, the light emitting unit 107, the aroma generating unit 108, and the operation unit 109 have been described above, so the description thereof will be omitted here.

[0030] The amplifier 105 amplifies the acoustic signal output from the speaker 106. The amplifier 105 may support high-resolution. Thereby, higher-quality sound can be output from the 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 by electronic devices mounted on the vehicle 1.

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

[0033] Further, the ECU 100 may include a non-volatile memory. Video content may be stored in the memory. Content related to the sound output from the speaker 106 in conjunction with the video content (hereinafter referred to as sound content) may be stored in the memory. Content for changing the light transmittance of the dimming film 104 in conjunction with the video content (hereinafter referred to as dimming content) may be stored in the memory. Content for causing the light emitting unit 107 to emit light in conjunction with the video content (hereinafter referred to as light emitting content) may be stored in the memory. Content for generating a fragrance from the fragrance generating unit 108 in conjunction with the video content (hereinafter referred to as fragrance content) may be stored in the memory. These contents may be stored in the memory in advance. Further, these contents may be updated as appropriate.

[0034] The ECU 100 performs a process of playing the video content and displaying it on the transparent display 102. In conjunction with the playback of the video content, the ECU 100 performs a process of transmitting the sound content to the amplifier 105 and outputting the sound content from the speaker 106. In conjunction with the playback of the video content, the ECU 100 performs a process of changing the transmittance of the transparent display 102 based on the dimming content. In conjunction with the playback of the video content, the ECU 100 performs a process of changing the light color and / or light intensity, etc. of the light emitting unit 107 based on the light emitting content. In conjunction with the playback of the video content, the ECU 100 performs a process of changing whether to generate a fragrance from the fragrance generating unit 108, the type of fragrance to be generated, and / or the intensity of the fragrance to be generated, etc. based on the fragrance content.

[0035] The ECU 100 receives information indicating the operation content (hereinafter referred to as operation information) from the operation unit 109, and based on the operation information, controls at least one of the transparent display 102, the dimming film 104, the amplifier 105, the light emitting unit 107, and the fragrance generating unit 108. For example, the ECU 100 controls the transparent display 102 based on the operation information to start or stop the playback of video content. For example, the ECU 100 controls the amplifier 105 based on the operation information to adjust the volume of the audio content. For example, the ECU 100 controls the dimming film 104 based on the operation information to adjust the maximum value and / or the minimum value of the transmittance, etc. For example, the ECU 100 controls the light emitting unit 107 based on the operation information to set whether to permit the light emission of the light emitting unit 107, and to adjust the light amount, etc. For example, the ECU 100 controls the fragrance generating unit 108 based on the operation information to set whether to permit the generation of the fragrance from the fragrance generating unit 108, and to set the intensity of the fragrance (for example, the intensity of the air volume for delivering the fragrance), etc. Note that the ECU 100 may be read as other terms such as a processor, a controller, a control unit, or a control circuit.

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

[0037] Next, with reference to FIGS. 5, 6, 7, 8, and 9, the process performed to assist in the fatigue recovery of a user sitting in the rear seat 22 will be described in detail.

[0038] Video content is an image that changes over time and has at least a first phase, a second phase after the first phase, a third phase after the second phase, and a fourth phase after the third phase. That is, 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. Note that a light-shielding curtain (not shown) may be provided on the rear door window 5, and the light-shielding curtain may be closed when playing the video content. Alternatively, a dimming film with a variable light transmittance may be provided on the rear door window 5, and the ECU 100 may automatically reduce the transmittance of the dimming film when playing the video content. Thereby, the rear compartment 24 can be darkened. Next, each phase will be described in detail.

[0039] <First Phase> In the first phase, a video that encourages relaxation is displayed on the transparent display 102 for a user (viewer) sitting in the rear seat 22. The transmittance of the transparent display 102 at the end of the first phase (the second transmittance) may be smaller than the transmittance of the transparent display 102 at the beginning of the first phase (the first transmittance). For example, in the first phase, as shown in FIG. 5, the transmittance of the transparent display 102 may change so as to decrease over time. Thereby, the line of sight of the user who was facing the scenery outside the vehicle through the front window 4 can be gradually guided to the video content displayed on the transparent display 102, and the user's consciousness can be smoothly directed to the video content.

[0040] The relaxation-promoting video may have, in the first half of the first phase, a natural video including a forest and a river as exemplified in FIG. 6 (hereinafter referred to as the natural video 210). By displaying such a natural video 210, the user's sense of tension can be alleviated, and the user can be promoted to relax. The relaxation-promoting video may have, in the second half of the first phase, a video in which the setting sun sinks below the horizon or the horizontal line as exemplified in FIG. 7 (hereinafter referred to as the setting sun video 220). By displaying such a setting sun video 220, the user can be made to be aware of the end of the active daytime, and the user can be promoted to relax.

[0041] The setting sun video 220 may have a horizon or a horizontal line along the longitudinal direction of the rectangular transparent display 102. And the setting sun video 220 may include a circular light-emitting part (the setting sun) partially in contact with the horizon or the horizontal line. The setting sun video 220 may be configured such that, as viewed from the user sitting in the rear seat 22, the horizon or the horizontal line of the setting sun video 220 coincides with or is parallel to the boundary line 300 between the front window 4 and the dashboard 7.

[0042] Thereby, the scenery outside the vehicle visible through the front window 4 above the boundary line 300 overlaps with the empty part above the horizon or the horizontal line of the setting sun video 220, and the dashboard 7 below the boundary line 300 overlaps with the ground or sea part below the horizon or the horizontal line of the setting sun video 220. Typically, since the ground or sea part below the horizon or the horizontal line of the setting sun video 220 is darker than the empty part above the horizon or the horizontal line of the setting sun video 220, the dashboard 7 becomes less visible through the transparent display 102. Therefore, the discomfort given to the user by the overlap between the video content displayed on the transparent display 102 and the scenery visible through the transparent display 102 can be reduced. In addition, the user's consciousness directed to the scenery outside the vehicle visible through the front window 4 can be smoothly guided to the video content displayed on the transparent display 102.

[0043] In the first phase, when the natural video 210 is displayed, the sound corresponding to the natural video 210 is output from the speaker 106, the light emitting unit 107 emits light with the light color and / or light intensity corresponding to the natural video 210, and the fragrance corresponding to the natural video 210 is generated from the fragrance generating unit 108. Also, in the first phase, when the sunset video 220 is displayed, the sound corresponding to the sunset video 220 is output from the speaker 106, the light emitting unit 107 emits light with the light color and / or light intensity corresponding to the sunset video 220, and the fragrance corresponding to the sunset video 220 is generated from the fragrance generating unit 108. Thereby, the user is promoted to relax not only through vision but also through hearing and smell.

[0044] <Second Phase> In the second phase, a video that promotes sleep (i.e., induces sleep) for the user (viewer) sitting in the rear seat 22 is displayed on the transparent display 102. The video that promotes sleep may be, for example, a video with relatively low brightness. Alternatively, in the second phase, video content may not be displayed on the transparent display 102.

[0045] The average value of the transmittance of the transparent display 102 during the first phase (the first average transmittance) may be greater than the average value of the transmittance of the transparent display 102 during the second phase (the second average transmittance). In other words, the average value of the transmittance of the transparent display 102 during the second phase (the second average transmittance) may be smaller than the average value of the transmittance of the transparent display 102 during the first phase (the first average transmittance). For example, the transmittance of the transparent display 102 in the second phase may be the minimum value within the range that can be set as the transmittance. Thereby, since the inside of the rear chamber 24 becomes relatively dark in the second phase, the user who relaxed in the first phase can be induced to sleep.

[0046] In the second phase, sound corresponding to the video that promotes sleep is output from the speaker 106, the light emitting unit 107 emits light in the light color and / or light intensity corresponding to the video that promotes sleep, and the fragrance corresponding to the video that promotes sleep is generated from the fragrance generating unit 108. Alternatively, in the second phase, sound may not be output from the speaker 106, and the light emitting unit 107 may not emit light. Thereby, the user is promoted to sleep not only through vision but also through hearing and smell.

[0047] <Third Phase> In the third phase, a video that promotes awakening is displayed on the transparent display 102 for a user (viewer) sitting in the rear seat 22. The transmittance of the transparent display 102 in the third phase may be a third transmittance smaller than the first transmittance. Also, 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 that can be set as the transmittance.

[0048] The video that promotes awakening may be such that the first half of the third phase is a video of the morning sun rising from the horizon or the horizontal line as illustrated in FIG. 8 (hereinafter referred to as the morning sun video 230). By displaying such a morning sun video 230, the user can be made aware of the beginning of an active day and the user's awakening can be promoted. The video that promotes awakening may be such that the second half of the third phase is a video including a single flower as illustrated in FIG. 9 (hereinafter referred to as the flower video 240). By displaying such a flower video 240, the user's attention can be attracted and the user's awakening can be promoted.

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

[0050] As a result, the view outside the vehicle visible through the front window 4 above the boundary line 300 overlaps with the part of the sky above the horizon or the horizontal line of the morning sun image 230, and the dashboard 7 below the boundary line 300 overlaps with the part of the ground or the sea below the horizon or the horizontal line of the morning sun image 230. Typically, the part of the ground or the sea below the horizon or the horizontal line of the morning sun image 230 is darker than the part of the sky above the horizon or the horizontal line of the morning sun image 230, so the dashboard 7 is less visible through the transparent display 102. Therefore, the discomfort caused to the user by the overlap between the video content displayed on the transparent display 102 and the view visible through the transparent display 102 can be reduced.

[0051] In the third phase, when the morning sun image 230 is displayed, the sound corresponding to the morning sun image 230 is output from the speaker 106, the light emitting part 107 emits light with the light color and / or light intensity corresponding to the morning sun image 230, and the fragrance corresponding to the morning sun image 230 is generated from the fragrance generating part 108. Also, in the third phase, when the flower image 240 is displayed, the sound corresponding to the flower image 240 is output from the speaker 106, the light emitting part 107 emits light with the light color and / or light intensity corresponding to the flower image 240, and the fragrance corresponding to the flower image 240 is generated from the fragrance generating part 108. Thereby, the user is prompted to wake up not only through vision but also through hearing and smell.

[0052] <Fourth Phase> In the fourth phase, at least a video that does not promote relaxation, sleep, or wakefulness is displayed on the transparent display 102 for the user (viewer) sitting in the rear seat 22. The video displayed in the fourth phase may be, for example, a video with relatively high brightness. Alternatively, in the fourth phase, video content may not be displayed on the transparent display 102.

[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 that is greater than the third transmittance. That is, the fourth transmittance may be a relatively high transmittance. For example, in the fourth phase, as shown in FIG. 5, the transmittance of the transparent display 102 may change so as to increase with the passage of time. Thereby, the line of sight of the user who was facing the video content displayed on the transparent display 102 can be gradually guided to the scenery outside the vehicle through the front window 4, and the user's consciousness can be smoothly directed to the scenery outside the vehicle.

[0054] The average value of the transmittance of the transparent display 102 during the fourth phase (the third average transmittance) may be greater than the average value of the transmittance of the transparent display 102 during the third phase (the fourth average transmittance). For example, the transmittance of the transparent display 102 in the fourth phase may increase with the passage of time and finally reach the maximum value within the range that can be set as the transmittance, as shown in FIG. 5. Thereby, since the transmittance of the transparent display 102 increases, the line of sight of the user who was facing the video content in the third phase can be gradually guided to the scenery outside the vehicle through the front window 4, and the user's consciousness can be smoothly directed to the actual scenery outside the vehicle.

[0055] In the fourth phase, sound may not be output from the speaker 106, the light emitting unit 107 may not emit light, and the fragrance may not be generated from the fragrance generating unit 108.

[0056] <Regarding transmittance> When the rear compartment 24 is completely darkened and the outside of the vehicle cannot be seen at all, the user may be more likely to get carsick. Therefore, the minimum transmittance of the transparent display 102 may be greater than 0. That is, the transparent display 102 may be configured not to completely block the light from outside the vehicle. The minimum transmittance of the transparent display 102 may be arbitrarily changeable.
