     BACKGROUND 
     The present disclosure relates to an experience system, an experience providing method, and a computer readable recording medium. 
     A technique of providing things other than driving in a moving body during automatic driving without causing a sense of incongruity in the movement of the moving body felt by a user wearing a head mounted display has been known (see, for example, International Publication No. 2017/142009). In this technique, the surrounding target objects sensed by sensors provided in the moving body are replaced with objects suitable for a virtual space and are then displayed on the head mounted display worn by the user. Therefore, the user may immerse himself/herself in the virtual space even in a case where the moving body has performed an avoidance operation of the target object.

     DETAILED DESCRIPTION 
     Hereinafter, exemplary embodiments of the present disclosure will be described in detail reference to with drawings. Note that the present disclosure is not limited by the following embodiments. In addition, in the following description, the same parts will be denoted by the same reference numerals. 
       FIG. 1  is a schematic diagram illustrating a schematic configuration of an experience system according to a first embodiment.  FIG. 2  is a block diagram illustrating a functional configuration of the experience system according to the first embodiment. 
     An experience system  1  illustrated in  FIG. 1  includes a moving body  10  and a wearable device  20  worn by a user U 1  and capable of communicating with the moving body  10  according to a predetermined communication standard. Here, the predetermined communication standard is, for example, one of 4G, 5G, Wi-Fi (Wireless Fidelity) (registered trademark), and Bluetooth (registered trademark). In addition, an automobile will be described as an example of the moving body  10  in the following description, but the moving body  10  is not limited thereto, and may be a bus, a truck, a drone, an airplane, a ship, a train, or the like. Note that in the first embodiment, the wearable device  20  functions as a display device. 
     First, a functional configuration of the moving body  10  will be described. The moving body  10  includes at least a speed sensor  11 , an image capturing device  12 , a sight line sensor  13 , an air conditioner  14 , a fragrance device  15 , a car navigation system  16 , a communication unit  18 , and an electronic control unit (ECU)  19 . 
     The speed sensor  11  detects speed information regarding a speed of the moving body  10  at the time of movement of the moving body  10 , and outputs this speed information to the ECU  19 . 
     A plurality of image capturing devices  12  are provided outside and inside the moving body  10 . For example, the image capturing devices  12  are provided at least at four places on the front, back, left, and right of the moving body  10  so that an image capturing angle of view is 360°. In addition, the image capturing device  12  generates image data by capturing an image of an external space, and outputs the image data to the ECU  19 . Further, the image capturing device  12  is provided on the exterior of the ceiling of the moving body  10  or in the vicinity of an instrument panel, generates image data by capturing an image of a vertical direction of the moving body  10 , and outputs the image data to the ECU  19 . The image capturing device  12  is configured using an optical system configured using one or more lenses and an image sensor such as a charge coupled device (CCD) or a complementary metal oxide semiconductor (CMOS) generating image data by receiving a subject image formed by the optical system. 
     The sight line sensor  13  detects sight line information including a sight line and a retina of the user U 1  who has ridden in the moving body  10 , and outputs the detected sight line information to the ECU  19 . The sight line sensor  13  is configured using an optical system configured using one or more lenses, an image sensor such as a CCD or a CMOS, a memory, and a processor having hardware such as a central processing unit (CPU) or a graphics processing unit (GPU). The sight line sensor  13  detects a non-moving portion of an eye of the user U 1  as a reference point (for example, an inner corner of the eye) using, for example, well-known template matching, and detects a moving portion (for example, an iris) of the eye as a moving point. Then, the sight line sensor  13  detects the sight line of the user U 1  based on a positional relationship between the reference point and the moving point, and outputs a detection result to the ECU  19 . Further, the sight line sensor  13  detects the retina of the user U 1  and outputs a detection result to the ECU  19 . 
     Note that the sight line sensor  13  detects the sight line of the user U 1  by a visible camera in the first embodiment, but the sight line sensor  13  is not limited thereto, and may detect the sight line of the user U 1  by an infrared camera. In a case where the sight line sensor  13  is configured by the infrared camera, the sight line sensor  13  irradiates the user U 1  with infrared light by an infrared light emitting diode (LED), detects a reference point (for example, a corneal reflex) and a moving point (for example, a pupil) from the image data generated by capturing an image of the user U 1  with the infrared camera, and detects the sight line of the user U 1  based on a positional relationship between the reference point and the moving point. 
     The air conditioner  14  blows (supplies) a wind (hereinafter referred to as an “air-conditioned wind”) air-conditioned to a temperature and a humidity set by the user from an air outlet through a duct provided in the moving body  10  into the moving body  10  under the control of the ECU  19 . The air conditioner  14  includes a first air conditioning unit  141 , a second air conditioning unit  142 , and an environment sensor  143 . The first air conditioning unit  141  blows the air-conditioned wind to a front seat  101 . The second air conditioning unit  142  generates an airflow that flows from the front of the moving body  10  to the rear of the moving body  10  in the moving body  10  by blowing the air-conditioned wind from a head of the user U 1  seated on the front seat  101  toward a rear side along a longitudinal direction of the moving body  10  when the moving body  10  is in open mode. The environment sensor  143  detects an external environment of the moving body  10  and outputs a detection result to the ECU  19 . Here, the external environment is a temperature and a humidity. The environment sensor  143  is realized using a temperature sensor, a humidity sensor, and the like. Note that a detailed configuration of the air conditioner  14  will be described later. 
     The fragrance device  15  supplies a predetermined fragrance to the air conditioner  14  under the control of the ECU  19 . The fragrance device  15  is realized using a plurality of accommodating portions accommodating each of a plurality of fragrant agents, a discharge pump supplying the fragrant agents accommodating in each of the plurality of accommodating portions to the air conditioner  14 , and the like. 
     The car navigation system  16  includes a global positioning system (GPS) sensor  161 , a map database  162 , a notification device  163 , and an operation unit  164 . 
     The GPS sensor  161  receives signals from a plurality of GPS satellites or transmission antennas, and calculates a position of the moving body  10  based on the received signals. The GPS sensor  161  is configured using a GPS receiving sensor or the like. Note that in the first embodiment, direction accuracy of the moving body  10  may be improved by mounting a plurality of GPS sensors  161 . 
     The map database  162  stores various map data. The map database  162  is configured using a recording medium such as a hard disk drive (HDD) or a solid state drive (SSD). 
     The notification device  163  includes a display unit  163   a  that displays an image, a video, and character information, and a voice output unit  163   b  that generates a sound such as a voice or an alarm sound. The display unit  163   a  is configured using a display such as a liquid crystal display or an organic electroluminescence (EL) display. The voice output unit  163   b  is configured using a speaker or the like. 
     The operation unit  164  receives an input of an operation of the user U 1  and supplies signals corresponding to various received operation contents to the ECU  19 . The operation unit  164  is realized using a touch panel, buttons, switches, a jog dial, or the like. 
     The car navigation system  16  configured as described above notifies the user U 1  of information including a road on which the moving body  10  is currently traveling, a route to a destination, and the like, by the display unit  163   a  and the voice output unit  163   b  by superimposing a current position of the moving body  10  acquired by the GPS sensor  161  on the map data stored in the map database  162 . 
     A recording unit  17  records various information regarding the moving body  10 . The recording unit  17  records virtual image data or various information that the ECU  19  outputs to the wearable device  20  via the communication unit  18  in a case where the moving body  10  and the wearable device  20  are in a communication state. The recording unit  17  is configured using a recording medium such as an HDD and an SSD. 
     The communication unit  18  communicates with various devices according to a predetermined communication standard under the control of the ECU  19 . Specifically, the communication unit  18  transmits various information to the wearable device  20  worn by the user U 1  who has ridden in the moving body  10  or another moving body  10  and receives various information from the wearable device  20  or another moving body  10 , under the control of the ECU  19 . 
     The ECU  19  controls an operation of each unit constituting the moving body  10 . The ECU  19  is configured using a memory and a processor having hardware such as a CPU. The ECU  19  generates a virtual image in which at least a part of a roof of the moving body  10  is opened and which includes the sky above the moving body  10  and the surrounding landscape of the moving body  10 , and outputs the virtual image to the wearable device  20 . Further, the ECU  19  controls the wind-blowing of the air conditioner  14  in conjunction with the display of the virtual image in the wearable device  20 . For example, the ECU  19  controls a wind volume of wind to be blown by the air conditioner  14  based on the speed information regarding the speed of the moving body  10  acquired from the speed sensor  11 . 
     Next, a functional configuration of the wearable device  20  will be described.  FIG. 3  is a diagram illustrating a schematic configuration of the wearable device  20 . 
     The wearable device  20  illustrated in  FIGS. 1 to 3  is augmented reality (AR) glasses for performing so-called AR, and virtually displays an image, a video, character information, and the like, in a visual field area of the user U 1 . Note that the AR glasses will be described as an example of the wearable device  20  in the following description, but the wearable device is not limited thereto, and may be a head mounted display (HMD) for mixed reality (MR) or virtual reality (VR). In this case, the HMD displays an image, a video, character information, and the like, that may be viewed stereoscopically by superimposing a real world on a virtual world (digital space), to the user U 1 . 
     The wearable device  20  includes an image capturing device  21 , a behavior sensor  22 , a sight line sensor  23 , a projection unit  24 , a GPS sensor  25 , a wearing sensor  26 , a communication unit  27 , and a control unit  28 . 
     As illustrated in  FIG. 3 , a plurality of image capturing devices  21  are provided in the wearable device  20 . The image capturing device  21  generates image data by capturing an image of a front of the sight line of the user U 1  and outputs the image data to the control unit  28 , under the control of the control unit  28 . The image capturing device  21  is configured using an optical system configured using one or more lenses and an image sensor such as a CCD or a CMOS. 
     The behavior sensor  22  detects behavior information regarding behavior of the user U 1  who has worn the wearable device  20 , and outputs a detection result to the control unit  28 . Specifically, the behavior sensor  22  detects an angular velocity and an acceleration generated in the wearable device  20  as the behavior information, and outputs a detection result to the control unit  28 . Further, the behavior sensor  22  detects an absolute direction as the behavior information by detecting geomagnetism, and outputs a detection result to the control unit  28 . The behavior sensor  22  is configured using a three-axis gyro sensor, a three-axis acceleration sensor, and a three-axis geomagnetic sensor (electronic compass). 
     The sight line sensor  23  detects a direction of the sight line of the user U 1  who has worn the wearable device  20 , and outputs a detection result to the control unit  28 . The sight line sensor  23  is configured using an optical system, an image sensor such as a CCD or a CMOS, a memory, and a processor having hardware such as a CPU. The sight line sensor  23  detects a non-moving portion of an eye of the user U 1  as a reference point (for example, an inner corner of the eye) using, for example, well-known template matching, and detects a moving portion (for example, an iris) of the eye as a moving point. Then, the sight line sensor  23  detects a direction of the sight line of the user U 1  based on a positional relationship between the reference point and the moving point. 
     The projection unit  24  projects an image, a video, and character information toward a retina of the user U 1  who has worn the wearable device  20  under the control of the control unit  28 . The projection unit  24  is configured using an RGB laser beam that emits each laser beam of RGB, a micro-electromechanical systems (MEMS) mirror that reflects the laser beam, a reflection mirror that projects the laser beam reflected from the MEMS mirror onto the retina of the user U 1 , and the like. Note that the projection unit  24  may display the image, the video, and the character information by projecting the image, the video, and the character information onto a lens unit of the wearable device  20  under the control of the control unit  28 . 
     The GPS sensor  25  calculates position information regarding a position of the wearable device  20  based on signals received from a plurality of GPS satellites, and outputs the calculated position information to the control unit  28 . The GPS sensor  25  is configured using a GPS receiving sensor or the like. 
     The wearing sensor  26  detects a worn state of the user U 1  and outputs a detection result to the control unit  28 . The wearing sensor  26  is configured using a pressure sensor that detects a pressure when the user U 1  has worn the wearable device  20 , a vital sensor that detects vital information such as a body temperature, a pulse, brain waves, a blood pressure, and a perspiration state of the user U 1 , and the like. 
     The communication unit  27  transmits various information to the moving body  10  or an external server and receives various information from the moving body  10  or the external server according to a predetermined communication standard under the control of the control unit  28 . The communication unit  27  is configured using a communication module capable of wireless communication. 
     The control unit  28  controls an operation of each unit constituting the wearable device  20 . The control unit  28  is configured using a memory and a processor having hardware such as a CPU. The control unit  28  causes the projection unit  24  to output a virtual image input from the moving body  10  or the server within the visual field area of the user U 1  based on the sight line information of the user U 1  detected by the sight line sensor  23  and the behavior information of the user U 1 . 
     Next, a schematic configuration of the air conditioner  14  will be described.  FIG. 4  is a diagram illustrating a schematic configuration of the first air conditioning unit  141  included in the air conditioner  14 .  FIG. 5  is a diagram illustrating a schematic configuration of the second air conditioning unit  142  included in the air conditioner  14 .  FIG. 6  is a schematic view of an airflow of an air-conditioned wind of the second air conditioning unit  142  included in the air conditioner  14  when viewed from a front surface side of the moving body  10 .  FIG. 7  is a schematic view of the airflow of the air-conditioned wind of the second air conditioning unit  142  included in the air conditioner  14  when viewed from a side surface side of the moving body  10 . Note that a case where the moving body  10  is a vehicle model having two rows of seats, that is, front seats  101  and rear seats  102  has been described in the first embodiment, but may be a vehicle model having one row or three rows of seats. 
     First, the first air conditioning unit  141  will be described. The first air conditioning unit  141  includes air outlets  141   a  provided at the center of an instrument panel  100  of the moving body  10  and air outlets  141   b  provided on both sides of the instrument panel  100 , as illustrated in  FIG. 4 . The first air conditioning unit  141  blows (supplies) an air-conditioned wind to the user U 1  seated on the front seat  101  through the air outlets  141   a  and the air outlets  141   b  under the control of the ECU  19 . The first air conditioning unit  141  is configured using a duct, an evaporator, a heater core, a fan, and the like. Note that the first air conditioning unit  141  is the same as that provided in a normal vehicle, and a detailed description thereof will thus be omitted. 
     Next, the second air conditioning unit  142  will be described. The second air conditioning units  142  illustrated in  FIGS. 5 to 7  include, respectively, suppliers  142   a  that supply air-conditioned winds and roof ducts  142   b  that extend from the front to the rear along a roof  103  in the longitudinal direction of the moving body  10 . 
     The supplier  142   a  supplies the air-conditioned wind to the roof duct  142   b  under the control of the ECU  19 . The supplier  142   a  is configured using a duct, an evaporator, a heater core, a fan, and the like. Note that although the suppliers  142   a  are provided independently for each of left and right roof ducts  142   b , the air-conditioned winds may be supplied to the left and right roof ducts  142   b  by one supplier  142   a . Further, the supplier  142   a  may be shared with the first air conditioning unit  141 . In this case, a damper that switches a supply destination of the air-conditioned wind under the control of the ECU  19 , or the like, may be provided between the duct of the first air conditioning unit  141  and the roof duct  142   b  to switch the air-conditioned wind supplied from the supplier  142   a.    
     The left and right roof ducts  142   b  are provided symmetrically with respect to a center line passing through the longitudinal direction of the moving body  10 . The left and right roof ducts  142   b  have the same structure as each other. For this reason, the left roof duct  142   b  will hereinafter be described. 
     The roof duct  142   b  has an air outlet  142   c . The air outlet  142   c  is provided on the roof  103  of a front side of the moving body  10 . The air outlet  142   c  blows an air-conditioned wind W 1  from a head of the user U 1  seated on the front seat  101  (seat) toward the rear seat  102  of the moving body  10 . 
     The second air conditioning unit  142  configured as described above blows the air-conditioned wind W 1  flowing from the head of the user U 1  seated on the front seat  101  toward the rear seat  102  of the moving body  10  through the air outlet  142   c , as illustrated in  FIGS. 5 and 6 , under the control of the ECU  19 . In this case, the air-conditioned wind W 1  becomes an airflow flowing from the front seat  101  to the rear seat  102  along the roof  103  of the moving body  10 . 
     Next, processing executed by the experience system  1  will be described.  FIG. 8  is a flowchart illustrating an outline of processing executed by the experience system  1 . 
     As illustrated in  FIG. 8 , the ECU  19  first determines whether or not a mode of the moving body  10  is set to an open mode (Step S 101 ). Specifically, the ECU  19  determines whether or not an instruction signal for instructing the open mode has been input from the operation unit  164 . In a case where the ECU  19  has determined that the mode of the moving body  10  is set to the open mode (Step S 101 : Yes), the experience system  1  proceeds to Step S 102  to be described later. On the other hand, in a case where the ECU  19  has determined that the mode of the moving body  10  is not set to the open mode (Step S 101 : No), the experience system  1  proceeds to Step S 113  to be described later. 
     In Step S 102 , the ECU  19  outputs roof opening moving image data in which the roof  103  of the moving body  10  transitions from a closed state to an opened state, recorded by the recording unit  17 , to the wearable device  20  via the communication unit  18 . In this case, the control unit  28  of the wearable device  20  causes the projection unit  24  to project a video corresponding to the roof opening moving image data input from the moving body  10  via the communication unit  27 . At this time, the ECU  19  may superimpose the video corresponding to the roof opening moving image data in which the roof  103  of the moving body  10  transitions from the closed state to the opened state, stored by the recording unit  17 , on an image corresponding to the image data generated by the image capturing device  12 , and output the video superimposed on the image to the wearable device  20 . Therefore, the user U 1  may virtually experience that the roof  103  of the moving body  10  switches from the closed state to the opened state. Further, the user U 1  may visually recognize the state of the roof  103  of the moving body  10 , and may thus grasp that the moving body  10  is transformed into the open mode (an open car mode). 
     Subsequently, the ECU  19  acquires the speed information of the moving body  10  from the speed sensor  11  (Step S 103 ), and controls a wind volume and a wind direction of the air conditioner  14  based on the speed information acquired from the speed sensor  11  (Step S 104 ) 
     Thereafter, the ECU  19  determines whether or not the roof  103  of the moving body  10  in the video virtually viewed by the user is in the opened state based on the roof opening moving image data output to the wearable device  20  (Step S 105 ). In a case where the ECU  19  has determined that the roof  103  of the moving body  10  in the video virtually viewed by the user is in the opened state (Step S 105 : Yes), the experience system  1  proceeds to Step S 106  to be described later. On the other hand, in a case where the ECU  19  has determined that the roof  103  of the moving body  10  in the video virtually viewed by the user is not in the opened state (Step S 105 : No), the experience system  1  returns to Step S 102  described above. 
     In Step S 106 , the ECU  19  acquires the position information of the moving body  10  from the GPS sensor  161 , acquires the image data from the image capturing device  12 , acquires the sight line information from the sight line sensor  13 , and acquires the speed information from the speed sensor  11 . 
     Subsequently, the ECU  19  outputs virtual image data in which the roof  103  of the moving body  10  is in the opened state and an external space of the moving body  10  in the vertical direction is photographed, into the visual field area of the user U 1  wearing the wearable device  20  via the communication unit  18  based on the sight line information acquired from the sight line sensor  13  and the image data acquired from the image capturing device  12  (Step S 107 ). In this case, as illustrated in  FIG. 9 , the control unit  28  of the wearable device  20  causes the projection unit  24  to project a video corresponding to the virtual image data input from the moving body  10  via the communication unit  27  into the visual field area of the user U 1 . At this time, the ECU  19  outputs a virtual image which corresponds to the image data acquired from the image capturing device  12  and in which the roof  103  of the moving body  10  is in the opened state, to the wearable device  20 . Further, the ECU  19  outputs a virtual image in which the external space of the moving body  10  in the vertical direction is photographed to the wearable device  20  by making a brightness of the virtual image higher than that of an image corresponding to the image data captured by the image capturing device  12 . For example, the ECU  19  makes at least one of saturation and brightness values of the virtual image higher than at least one of saturation and brightness values of the image corresponding to the image data acquired from the image capturing device  12  to output the virtual image to the wearable device  20 . Therefore, the user U 1  may experience that the roof  103  of the moving body  10  is in the opened state (an open car state). Further, since the brightness of the virtual image is higher than that of the image corresponding to the image data captured by the image capturing device  12 , the user U 1  may virtually experience sunbeam shining through branches of trees, sunlight, or the like. 
     Thereafter, the ECU  19  controls the fragrance supplied by the fragrance device  15  based on the position information acquired from the GPS sensor  161  (Step S 108 ). For example, in a case where a place where the moving body  10  travels is a forest, a mountain or the like, the ECU  19  causes the fragrance device  15  to supply a fragrance that may allow the fragrance device  15  to feel a mountain or a tree based on the position information acquired from the GPS sensor  161 . 
     Subsequently, the ECU  19  controls a wind volume and a wind direction of the air-conditioned wind blown by the second air conditioning unit  142  of the air conditioner  14  based on the speed information acquired from the speed sensor  11  (Step S 109 ). In this case, the ECU  19  causes the second air conditioning unit  142  to blow the air-conditioned wind W 1  whose wind volume corresponds to the speed of the moving body  10 . Further, the ECU  19  adjusts a temperature and a humidity of the air-conditioned wind W 1  blown by the second air conditioning unit  142  by controlling the supplier  142   a  based on the detection result detected by the environment sensor  143 . Therefore, the user U 1  may virtually feel a wind experienced at the time of ridding in the moving body  10  in a case where the roof  103  is in an open state by the air-conditioned wind (for example, the air-conditioned wind W 1  illustrated in  FIGS. 6 and 7  described above), and may thus experience similar presence at the time of driving the moving body  10  in a case where the roof  103  is in the open state. Further, since the fragrance supplied from the fragrance device  15  is included in the air-conditioned wind W 1 , the user U 1  may experience an odor according to the surrounding environment of the moving body  10 , and may experience more presence. Furthermore, the user U 1  may virtually experience a wind according to a humidity and a temperature at the time of ridding in the moving body  10  in a case where the roof  103  is in the open state. 
     Thereafter, the ECU  19  determines whether or not an instruction signal for terminating the open mode has been input from the operation unit  164  (Step S 110 ). In a case where it has been determined that the instruction signal for terminating the open mode has been input from the ECU  19  (Step S 110 : Yes), the experience system  1  proceeds to Step S 111  to be described later. On the other hand, in a case where it has been determined that the instruction signal for terminating the open mode has not been input from the ECU  19  (Step S 110 : No), the experience system  1  returns to the above-described Step S 106 . 
     Subsequently, the ECU  19  outputs roof closing moving image data in which the roof  103  transitions from the opened state to the closed state from the recording unit  17  to the wearable device  20  (Step S 111 ). Therefore, the user U 1  may virtually experience that the roof  103  of the moving body  10  switches from the opened state to the closed state, and may grasp that the moving body  10  has terminated the open mode. 
     Thereafter, the ECU  19  determines whether or not the moving body  10  has stopped (Step S 112 ). Specifically, the ECU  19  determines whether or not the moving body  10  has stopped based on the speed information acquired from the speed sensor  11 . In a case where the ECU  19  has determined that the moving body  10  has stopped (Step S 112 : Yes), the experience system  1  ends this processing. On the other hand, in a case where the ECU  19  has determined that the moving body  10  has not stopped (Step S 112 : No), the experience system  1  returns to Step S 101 . 
     In Step S 113 , the ECU  19  controls the air conditioner  14  with air conditioning according to a setting of the user. Specifically, the ECU  19  causes the first air conditioning unit  141  to blow the air-conditioned wind W 1  to the user U 1 . 
     According to the first embodiment described above, the ECU  19  generates a virtual image P 1 , outputs the virtual image P 1  to the wearable device  20 , and controls the wind-blowing of the air conditioner  14  in conjunction with the display of the virtual image P 1  in the wearable device  20 . For this reason, the user U 1  may experience the presence according to visual information. 
     In addition, according to the first embodiment, the ECU  19  acquires the speed information regarding the speed of the moving body  10  from the speed sensor  11 , and controls a wind volume of wind to be blown by the air conditioner  14  based on the speed information. For this reason, the user U 1  may experience the wind that he/she may feel in a case where the roof  103  has been turned into the opened state in the moving body  10 . 
     In addition, according to the first embodiment, the roof duct  142   b  of the second air conditioning unit  142  has the air outlet  142   c  (first air outlet) that blows the wind from a front pillar side of the moving body  10  toward the front seat  101  of the front side of the moving body  10 . For this reason, the user U 1  may experience an airflow of the wind flowing in an internal space of the moving body  10  in a case where the roof  103  has been turned into the opened state in the moving body  10 . 
     In addition, according to the first embodiment, the ECU  19  acquires each of an external temperature and humidity in the moving body  10 , and controls a temperature and a humidity of the wind blown by the air conditioner  14  based on each of the external temperature and humidity. For this reason, the user U 1  may realistically experience the temperature or the humidity of the wind that he/she may feel in a case where the roof  103  has been turned into the opened state in the moving body  10 . 
     In addition, according to the first embodiment, the ECU  19  outputs the video corresponding to the roof opening moving image data in which the roof  103  of the moving body  10  transitions from the closed state to the opened state, to the wearable device  20 , and outputs the virtual image to the wearable device  20  in a case where the roof  103  of the moving body  10  in the video has been turned into the opened state. For this reason, the user U 1  may virtually experience that the roof  103  of the moving body  10  switches from the closed state to the opened state. 
     In addition, according to the first embodiment, the fragrance device  15  is provided on a flow path in the roof duct  142   b  of the air conditioner  14  and supplies a fragrant substance. For this reason, the user U 1  may virtually experience an external environment of the moving body  10 . 
     In addition, according to the first embodiment, the ECU  19  acquires the position information regarding the position of the moving body  10  from the GPS sensor  161 , and controls the fragrant substance supplied by the fragrance device  15  based on the position information. For this reason, the user U 1  may virtually experience an environment according to a current position of the moving body  10 . 
     In addition, according to the first embodiment, the ECU  19  sequentially acquires a plurality of image data generated by continuously capturing at least images of a moving direction and the vertical direction of the moving body  10  and continuous in terms of time from the image capturing device  12 , and continuously generates the virtual images in time series based on the plurality of image data. For this reason, the user U 1  may virtually experience a state where the roof  103  has been opened in the moving body  10 . 
     In addition, according to the first embodiment, the image capturing device  12  is provided on an exterior side of the roof  103  of the moving body  10  and generates image data, and it is thus possible to generate image data in a state where the roof  103  of the moving body  10  has been opened. 
     In addition, according to the first embodiment, the ECU  19  acquires the sight line information regarding the sight line of the user U 1  riding in the moving body  10 , and displays the virtual image in the visual field area of the user U 1  based on the sight line information. For this reason, the user U 1  may immerse himself/herself in the virtual image because the virtual image is displayed on the sight line. 
     In addition, according to the first embodiment, the ECU  19  increases a brightness of the virtual image, and outputs the virtual image to the wearable device  20 . For this reason, the user U 1  may virtually experience a situation of sunbeam shining through branches of trees or sunlight in a case where the roof  103  of the moving body  10  is in the opened state. 
     In addition, according to the first embodiment, the wearable device  20  displays the virtual image on the visual field area of the user U 1 . For this reason, the user U 1  may immerse himself/herself in the virtual image. 
     In addition, according to the first embodiment, in a case where the instruction signal for instructing the open mode has been input from the operation unit  164 , the ECU  19  outputs the virtual image to the wearable device  20 , and it is thus possible to transition the roof  103  of the moving body  10  to the open mode according to an intention of the user U 1 . 
     Next, a second embodiment will be described. In the first embodiment, the second air conditioning unit  142  blows the air-conditioned wind flowing from the head of the user U 1  to the rear seat  102  of the moving body  10  when the moving body  10  is in the open mode, but in a second embodiment, the first air conditioning unit  141  blows an air-conditioned wind from a front surface and a side surface toward the user U 1  who has ridden in the moving body  10 . Hereinafter, an airflow of an air-conditioned wind blown by the first air conditioning unit  141  when the moving body  10  is in the open mode will be described. Note that the same components as those of the experience system  1  according to the first embodiment described above will be denoted by the same reference numerals, and a detailed description thereof will be omitted. 
       FIG. 10  is a schematic view of an airflow of an air-conditioned wind by the first air conditioning unit  141  included in an air conditioner  14  according to a second embodiment when viewed from a front surface side.  FIG. 11  is a schematic view of the airflow of the air-conditioned wind by the first air conditioning unit  141  included in the air conditioner  14  according to the second embodiment when viewed from a side surface side. 
     As illustrated in  FIGS. 10 and 11 , the first air conditioning unit  141  blows an air-conditioned wind W 10  from an air outlet  141   a  (first air outlet) provided in an instrument panel  100  and an air-conditioned wind W 1   l  from an air outlet  141   b  (second air outlet) so as to spray the air-conditioned wind to an upper portion (head) and a side surface (side pillar side) of the user U 1  under the control of the ECU  19 . In this case, the ECU  19  causes the first air conditioning unit  141  to supply the air-conditioned wind by an air volume equivalent to an airflow by a vehicle speed corresponding to the speed information of the moving body  10  based on the speed information acquired from the speed sensor  11 . 
     According to the second embodiment described above, the ECU  19  controls the first air conditioning unit  141  to blow the air-conditioned wind W 10  from the air outlet  141   a  and the air-conditioned wind W 11  from the air outlet  141   b . For this reason, the user U 1  may experience the wind that he/she may feel in a case where the roof  103  has been turned into the opened state in the moving body  10 . 
     Note that the air-conditioned wind has been supplied to the user U 1  using only the first air conditioning unit  141  in the open mode in the second embodiment, but the air-conditioned wind may be supplied to the user U 1  using the first air conditioning unit  141  together with the second air conditioning unit  142 . 
     Next, a third embodiment will be described. A second air conditioning unit according to a third embodiment has a configuration different from that of the second air conditioning unit  142  according to the first embodiment described above. Specifically, the second air conditioning unit according to the third embodiment generates an entrained airflow generated in a case where the roof of the moving body is in the opened state by further blowing an air-conditioned wind from behind the user who has ridden in the moving body. Hereinafter, a configuration of the second air conditioning unit  142  according to the third embodiment will be described. Note that the same components as those of the experience system  1  according to the first embodiment described above will be denoted by the same reference numerals, and a detailed description thereof will be omitted. 
       FIG. 12  is a schematic diagram illustrating a schematic configuration of a second air conditioning unit in an air conditioner according to a third embodiment.  FIG. 13  is a front view schematically illustrating an airflow by the second air conditioning unit.  FIG. 14  is a side view schematically illustrating the airflow by the second air conditioning unit. 
     A second air conditioning units  144  illustrated in  FIGS. 12 to 14  include roof ducts  144   b , respectively, instead of the roof ducts  142   b  according to the first embodiment described above. The roof ducts  144   b  are provided symmetrically with respect to a center line passing through the longitudinal direction of the moving body  10 . The left and right roof ducts  144   b  have the same structure as each other. For this reason, the left roof duct  144   b  will hereinafter be described. 
     The roof duct  144   b  has an air outlet  142   c  and an air outlet  144   a . The air outlet  144   a  is provided on a roof  103  of a rear side of the moving body  10 . The air outlet  144   a  blows an air-conditioned wind W 20  from behind the head of the user U 1  seated on the front seat  101 . 
     The second air conditioning unit  144  configured as described above supplies an air-conditioned wind W 1  flowing from the head of the user U 1  seated on the front seat  101  toward the rear seat  102  of the moving body  10  through the air outlet  142   c  and the air outlet  144   a , as illustrated in  FIGS. 13 and 14 . Further, the second air conditioning unit  144  supplies the air-conditioned wind W 20  from a rear of the user U 1  through the air outlet  144   a , as illustrated in  FIGS. 13 and 14 . In this case, the air-conditioned wind W 20  becomes an entangled airflow generated in a case where the roof  103  of the moving body  10  is in the opened state (in the open mode). 
     According to the third embodiment described above, the roof duct  144   b  has the air outlet  144   a  provided behind the front seat  101  and blowing the wind from the rear side of the user U 1  seated on the front seat  101  to the front side of the user U 1 . For this reason, the user U 1  may experience the wind that he/she may feel in a case where the roof  103  has been turned into the opened state in the moving body  10 , and may experience the entrained airflow generated in a case where the roof  103  of the moving body  10  is in the opened state (in the open mode). 
     Note that according to the third embodiment, the ECU  19  causes the second air conditioning unit  144  to blow the air-conditioned wind W 1  and the air-conditioned wind W 20  to the user U 1  in the open mode, but may cause the first air conditioning unit  141  to blow the air-conditioned wind W 10  and the air-conditioned wind W 11  to the user U 1 . 
     An example using the eyeglasses-type wearable device  20  that may be worn by the user has been described in the first to third embodiments, but the present disclosure is not limited thereto, and may be applied to various wearable devices. The present disclosure may also be applied to, for example, a contact lens-type wearable device  20 A having an image capturing function, as illustrated in  FIG. 15 . Further, the present disclosure may also be applied to a device that performs direct transmission to a brain of the user U 1 , such as a wearable device  20 B of  FIG. 16  or an intracerebral chip-type wearable device  20 C of  FIG. 17 . Furthermore, the wearable device may be configured in a shape of a helmet with a visor as in a wearable device  20 D of  FIG. 18 . In this case, the wearable device  20 D may project and display an image onto the visor. 
     In addition, the wearable device  20  has projected the image onto the retina of the user to cause the user to visually recognize the image in the first to third embodiments, but the image may be projected and displayed on a lens such as eyeglasses, for example. 
     In addition, the virtual image has been displayed using the wearable device  20  in the first to third embodiments, but the virtual image may be displayed by providing, for example, a display panel such as liquid crystal or an organic electroluminescence (EL) on the entire inner wall surface of the roof  103  of the moving body  10 . 
     In addition, the ECU  19  has acquired the image data from the image capturing device  12  in the first to third embodiments, but the ECU is not limited thereto, and may acquire the image data from an external server that records the image data. In this case, the ECU  19  may acquire the image data corresponding to the position information of the moving body  10  from the external server. 
     In addition, in the first to third embodiments, the “unit” described above may be replaced by a “circuit” or the like. For example, the control unit may be replaced by a control circuit. 
     In addition, a program to be executed by the experience systems according to the first to third embodiments is recorded and provided as file data having an installable format or an executable format on a computer-readable recording medium such as a compact disk-read only memory (CD-ROM), a flexible disk (FD), a compact disk-recordable (CD-R), a digital versatile disk (DVD), a universal serial bus (USB) medium, or a flash memory. 
     In addition, the program to be executed by the experience systems according to the first to third embodiments may be configured to be stored on a computer connected to a network such as the Internet and be provided by being downloaded via the network. 
     Note that an order relationship of processing between steps has clarified using the expressions such as “first”, “thereafter”, and “subsequent” in the description of the flowchart in the present specification, but the order of processing to carry out the present embodiment is not uniquely defined by those expressions. That is, the order of processing in the flowchart described in the present specification may be changed as long as contradiction does not occur.

     According to the present disclosure, the processor generates the virtual image, outputs the virtual image to the display device, and controls the wind-blowing of the air conditioner in conjunction with the display of the virtual image in the display device. Therefore, an effect that it is possible to cause the user to experience the presence according to visual information in a virtual space or an augmented reality space is achieved.
