Note that the content described below is merely an example of the embodiment of the present invention, and the present invention is not limited to the following embodiment, and may be implemented in various other embodiments. is possible.

FIG. 1 is an external perspective view showing an example of a virtual experience seat system according to the present embodiment. The virtual experience seat system 1000 includes a seat 10 on which a user sits, a display device 20, a control device 30, and a remote control 15. The display device 20 is supported by a support ST and is arranged in front of the seat 10. The display device 20 is realized by, for example, a smartphone, a tablet terminal, a notebook PC (Personal Computer), a desktop PC, or the like. The virtual experience seat system 1000 allows a user seated on the seat 10 to virtually experience walking at scenic spots and tourist spots in Japan and abroad. The user seated on the seat 10 selects an experience course and the like by operating the remote control 15. In FIG. 1, the front-rear direction and the left-right direction are defined based on the user sitting on the seat 10 as shown in the figure.

The seat 10 includes a seat cushion section 11, a seat back section 12, a headrest section 13, and an armrest section 14. The control device 30 is arranged below the seat cushion section 11. On the inside of the seating surface 11a of the seat cushion section 11, pressure sensors PS1 to PS6 are provided to detect pressure exerted on the seat cushion section 11 from the body of a user sitting on the seat 10. Furthermore, pressure sensors PS7 and PS8 are also provided on the upper surface sides of the left and right armrest sections 14. Further, the headrest portion 13 is provided with a speaker 130. Each of the pressure sensors PS1 to PS8 and the speaker 130 described above and the control device 30 are connected by a harness (not shown).

As shown in FIG. 1, pressure sensors PS1 to PS3 and pressure sensors PS4 to PS6 provided on the seat cushion portion 11 are arranged at symmetrical positions on the seat surface of the seat cushion portion 11. Pressure sensors PS1, PS2, PS4, and PS5 are arranged at positions corresponding to the buttocks of the seated person on the seat cushion portion 11. Pressure sensors PS1 and PS4 are provided at positions corresponding to the lowest part of the sitting person's ischial bones. In this position, the load of the seated person is the greatest.

The pressure sensors PS3 and PS6 are located under the thighs of the seated person and detect pressure from the thighs of the seated person. Further, pressure sensors PS7 and PS8 provided on the armrest portion 14 are provided to detect a motion of the seated person hitting the front portion of the upper surface of the armrest portion 14. The pressure detection values detected by the pressure sensors PS1 to PS8 are input to the control device 30. The detected pressure value changes depending on the magnitude of the pressure value applied to the pressure sensors PS1 to PS8. For example, as the pressure value increases, the detected pressure value also increases.

FIG. 2 is a functional block diagram of the virtual experience seat system 1000. As described above, the virtual experience seat system 1000 includes the control device 30, pressure sensors PS1 to PS8, the speaker 130, and the display device 20. The control device 30 is constituted by an electronic control unit, and includes a computer having a CPU 301, a storage section 302 such as ROM or RAM, a wireless communication section 303, and other peripheral circuits. CPU 301 controls display device 20 and speaker 130 based on control software and control data stored in storage unit 302, pressure detection values from pressure sensors PS1 to PS8, command signals from remote control 15, and the like. The display device 20 receives video information from the control device 30 via the wireless communication section 201. For example, short-range wireless communication such as Wi-Fi (registered trademark) is used for wireless communication. Note that in the example shown in FIG. 2, the video information is transmitted by wireless communication, but wired communication may also be used.

The storage unit 302 of the control device 30 stores virtual experience game software and related data. The remote control 15 is provided with a power switch 151 for turning on and off the power of the control device 30, and operation buttons for performing input operations when playing a virtual experience game. For example, a trackball 152 for moving a cursor displayed on the screen of the display device 20, a confirmation button 153 for confirming settings, and the like are provided.

(Operation explanation)
When a user seated on the seat 10 in FIG. 1 turns on the power switch 151 of the remote controller 15, the control device 30 is turned on. When the control device 30 is turned on, the display device 20 is turned on, the virtual experience game software is started, and a startup screen is displayed on the display device 20. The startup screen is, for example, a display screen for course selection, and the user selects a desired course from a plurality of courses by operating operation buttons on the remote control 15. When a course is selected, the control device 30 causes the display device 20 to display a plan view of the selected course. All data regarding a plurality of courses is stored in the storage unit 302.

FIG. 3 is a diagram showing an example of a display image 200A showing a course plan view. In the course shown in FIG. 3, the end points of the course are A, B, and C, but the user is not limited to end points A, B, and C, and can select any point on the course as the start point and goal point. Use the trackball 152 to move the point selection cursor 201 to the desired position on the course, and press the confirm button 153 to confirm.The position of the cursor 201 (end point A) becomes the starting point (a). . The same applies to the setting operation of the goal point (end point C) (b). FIG. 3 shows a case where end point A is set as the start point and end point C is set as the goal point. Note that when changing settings, the user can return to the previous screen by placing the cursor 201 over the "back" icon 203 and operating the confirm button 153.

After setting the start point and goal point, place the cursor 201 over the "start" icon 202 and confirm with the confirm button 153 (c), and a landscape image at the start point of the selected course will be displayed on the display device 20. . A display image 200B shown in FIG. 4 is a diagram showing an example of a landscape image at the starting point. In the display image 200B, a footprint mark 204, the number of steps 205, a walking distance 206, and a remaining distance 207 are displayed superimposed on a landscape image.

A footprint mark 204 is a diagram showing the state of the stepping motion of the seated person. When the pressure sensors PS3 and PS6 (see FIG. 1) detect pressure from the thighs of the seated person, the footprint mark 204 is displayed, and when the thigh is lifted and the detected pressure value falls below a predetermined threshold, the footprint mark 204 is hidden. Become. When the seated person makes a stepping motion, the left and right footprint marks 204 are displayed alternately according to the pressure detection values of the pressure sensors PS3 and PS6, and the number of steps 205 is counted. The walking distance 206 is calculated by multiplying the counted number of steps 205 by a predetermined stride length. The remaining distance 207 is calculated by dividing the walking distance 206 from the distance from the set start point to the goal point.

The landscape image shown in the display image 200B of FIG. 4 is a landscape image in the direction of travel as seen from the viewpoint of a pedestrian located at the starting point. When the seated person starts stepping, the viewpoint is assumed to move by the walking distance. The display device 20 displays a landscape image that changes according to the movement of the viewpoint due to the stepping motion. FIG. 5 is a diagram showing changes in the landscape image displayed on the display device 20 when the viewpoint moves due to the stepping motion. FIG. 5A is a display image 200B showing a landscape image at the starting point, which is the same as the display image 200B shown in FIG. FIG. 5(b) is a display image 200C showing a landscape image when the viewpoint moves from the starting point in the traveling direction.

By performing the stepping motion in this way, the seated person can enjoy the scenery as if he were actually walking on the course. In addition, the speakers 130 installed in the headrests 13 generate environmental sounds at each point on the course (for example, chirping birds, the sound of leaves swaying in the wind, the sound of a river, etc.), increasing the sense of realism. It will be done.

The video data of each course stored in the storage unit 302 of the control device 30 is stored as a landscape video at each point on the course, that is, video data of a landscape video obtained when walking on the course. Further, both video data for walking the course in the forward direction and video data for walking in the reverse direction are stored. Furthermore, it is possible to display not only the image when looking in the direction of travel, but also the image when turning the head left and right and swinging the line of sight from side to side.For example, image data of 180 degrees in the horizontal direction can be stored. has been done. Conversely, if we consider an image of walking, 360° horizontal image data is stored.

By storing such video data in the storage unit 302, for example, the display device 20 can display an image similar to a landscape image when the line of sight is slowly turned to the left, that is, when the camera is slowly turned to the left. It can be configured so that it is displayed. A person seated on the seat 10 tilts his or her body to the left and shifts his or her center of gravity to the left, thereby tilting his or her line of sight to the left. The control device 30 estimates the shift of the center of gravity to the left from the pressure detection values of the pressure sensors PS1 to PS6. Conversely, when the seated person tilts his or her body to the right, an image similar to the landscape image that would be displayed if the seated person slowly turned his/her line of sight to the right is displayed on the display device 20.

6 and 7 are diagrams illustrating changes in the landscape image displayed on the display device 20 when the seated person tilts his or her body to the left or right. In FIG. 6, the landscape video indicated by the symbol D is a video that can be generated using the video data stored in the storage unit 302, and shows a part of the landscape at 180° in the horizontal direction. When the line of sight is directed in the direction of travel, the image within frame F1 is displayed on the display device 20 as a display image 200C shown in FIG. 7(a).

When the seated person tilts his or her body to the left, the line of sight viewing the scenery shifts to the left, and the image within frame F2 is displayed on the display device 20 as a display image 200D shown in FIG. 7(b). Conversely, when the seated person tilts his or her body to the right, the line of sight shifts to the right, and the image in frame F3 is displayed on the display device 20 as a display image 200E shown in FIG. 7(c). Note that in FIG. 6, frames F1 to F3 are displayed vertically shifted from each other for ease of understanding.

Note that instead of detecting the movement of the seated person's center of gravity, the above-mentioned landscape image may be displayed by the seated person hitting the pressure sensor portion of the armrest 14. In that case, when the seated person taps the pressure sensor PS7 part of the left armrest 14 once, an image similar to the image (video image) obtained when the camera is swung to the left by a predetermined angle Δθ at that point on the course is generated. A landscape image is displayed on the display device 20. Also, if you tap the button n times, a landscape image similar to that seen when the camera is swung to the left by an angle n×Δθ will be displayed. Conversely, when the pressure sensor PS8 portion of the right armrest 14 is tapped, the display device 20 displays a landscape image when the user turns his/her line of sight to the right.

As described above, in the virtual experience seat system 1000 of the present embodiment, even people with low physical strength can perform light exercise while enjoying realistic landscape images in which the landscape changes as the viewpoint moves. I can do it. Therefore, due to the desire to enjoy a realistic landscape image, even a simple movement of stepping on the seat 10 can be continued for a long time without getting tired. For example, an elderly person who has a knee injury and who has difficulty actually walking but is able to move his/her thighs up and down may use the virtual experience seat system 1000 of this embodiment to try stepping while enjoying a landscape image. This has the effect of preventing the weakening of the legs and hips. In addition, for a person with a leg disability, the setting may be changed to perform a walking motion by tapping the pressure sensors PS7 and PS8 of the armrest 14, for example.

In the present embodiment described above, the virtual experience game software main body is stored in the control device 30, and the virtual experience game can be enjoyed stand-alone. However, like an online game, the configuration may be such that a virtual experience game is played by connecting to a game server on a network. Further, although a pressure sensor is exemplified as a sensor, the sensor may be another type of sensor, such as a capacitance sensor. Moreover, when measuring pressure, a pressure distribution sensor can also be employed.

(Modification 1)
In the embodiment described above, the virtual experience game software main body is stored in the control device 30, and the virtual experience game can be enjoyed stand-alone. In Modified Example 1, the virtual experience game itself basically operates as a standalone system, and it is also configured to allow exchange of location information between systems and exchange of audio data using microphones and speakers. There is. Note that, like an online game, a configuration may be used in which a virtual experience game is played by connecting to a game server on a network.

FIG. 8 is a block diagram for explaining modification example 1. A server 50 managed by the manufacturer of the virtual experience seat system is provided on the Internet 40 network. Virtual experience seat systems 1000A and 1000B are connected to the Internet 40. In FIG. 8, for convenience of explanation, two virtual experience seat systems 1000A and 1000B are connected to the Internet 40, but the number of connected systems is not limited to two. In addition to the components shown in FIG. 2, the virtual experience seat systems 1000A and 1000B include a microphone 16 used by a person seated on the seat 10.

Each virtual experience seat system 1000A, 1000B is connected to a server 50 via the Internet 40 when the virtual experience game software is launched. In the database 51 of the server 50, information about each of the sold virtual experience systems 1000A and 1000B is registered. For example, information on a plurality of users who use each virtual experience system 1000A, 1000B is registered. Furthermore, when the virtual experience systems 1000A, 1000B are used, real-time walking position information on the course (hereinafter referred to as position information) is transmitted from the virtual experience systems 1000A, 1000B to the server 50, and 50 database 51.

For example, Mr. A, who uses the virtual experience system 1000A, and Mr. B, who uses the virtual experience system 1000B, are acquaintances, and settings are made to allow information sharing between Mr. A and Mr. B. Consider the case. In that case, position information can be exchanged between the virtual experience system 1000A and the virtual experience system 1000B via the server 50. In other words, the system allows virtual experience systems that have permission to share information to exchange location information.

FIG. 9 shows a display image 200B displayed on the display device 20 of the virtual experience system 1000A. This is basically the same as the display image 200B shown in FIG. 4, except that an icon 208 is displayed. In modification example 1, when Mr. B, who is exchanging location information, approaches a visible position while walking on the same course as Mr. A, the icon 208 representing Mr. B changes to a landscape image, as shown in FIG. will be displayed superimposed on top of the . Similarly, an icon representing Mr. A is displayed on the display device 20 of the virtual experience system 1000B. Note that the virtual experience systems 1000A and 1000B may further be provided with a camera for photographing the seated person, and the image of Mr. B photographed by the camera may be displayed on the face portion of the icon 208. In this way, in Modification 1, the user can not only enjoy a virtual walk alone, but also enjoy a walk together while communicating with an acquaintance connected via the Internet 40.

Note that if a malfunction occurs in hardware such as a pressure sensor, game software, etc., malfunction information may be transmitted to the server 50 via the Internet 40. If the game is interrupted due to a malfunction, the position information and the like at that time may be stored in the storage unit 302 of the control device 30, and the game may be restarted from the position at the time of interruption.

In modification example 1, the icon 208 of the user of the virtual experience system 1000B connected via the Internet 40 is displayed on the display device 20 of the virtual experience system 1000A in a superimposed manner on the landscape video. Another example of such an image representing an image that does not appear in actual scenery is a corporate advertisement. For example, displaying corporate advertisements in a natural manner within the landscape, such as on billboards with the company name, can increase advertising effectiveness. Furthermore, by displaying the corporate advertisement, the maker of the virtual experience system that manages the server 50 can earn royalties from displaying the corporate advertisement.

Further, as a mechanism of the virtual experience game, the total walking distance of the user may be stored in the storage unit 302, and points may be accumulated according to the total walking distance. In this case, the use of the system can be promoted by allowing some kind of reward to be obtained from the manufacturer according to the accumulated points. For example, one point is earned for every 10 km of walking, and when the number of points reaches 100 points, a new walking course is obtained.

(Modification 2)
In a second modification, a case will be described in which the virtual space seat system described above is applied to a vehicle seat. FIG. 10 is a diagram showing the arrangement of seats provided in vehicle 600. As shown in FIG. 10, a front seat 61, a second seat 62, and a third seat 63 are arranged on the floor of a vehicle 600 at predetermined intervals in the longitudinal direction of the vehicle interior. In Modification 2, a configuration similar to that of the seat 10 described above is applied to the third seat 63. That is, as shown in FIG. 12, which will be described later, the third seat 63 is provided with pressure sensors PS1 to PS6 and a speaker 130.

A pair of left and right lower rails 640 are fixedly arranged on the floor surface of the vehicle interior so as to extend in the longitudinal direction of the vehicle interior, as slide mechanisms 61 for the second seat 62 and the third seat 63. The slide mechanism 61 includes a lower rail 640, a first upper rail 641, and a second upper rail 642. A first upper rail 641 fixed to the lower surface of the second seat 62 and a second upper rail 642 fixed to the lower surface of the third seat 63 are attached to the pair of left and right lower rails 640. The upper rails 641, 642 are provided with electric motors M, and the upper rails 641, 642 are electrically moved to slide in the front and rear directions.

The second seat 62 is composed of a front seat cushion 621 and a rear seat cushion 622 that are divided into two parts in the front and rear, and a seat back 623 that is connected to the rear end of the rear seat cushion 622 so as to be able to rise and fall. As shown in FIG. 11, which will be described later, the front seat cushion 621 is configured to be tiltable in the vertical direction around its rear end. Similarly to the second seat 62, the third seat 63 also includes a front seat cushion 631 and a rear seat cushion 632 that are divided into two parts in the front and rear, and a seat back that is connected to the rear end of the rear seat cushion 632 so that it can be raised and folded. 633. As in the case of the front seat cushion 621, the front seat cushion 631 is configured to be tiltable in the vertical direction around its rear end.

FIG. 11 is a diagram showing a seat arrangement when playing the above-described virtual experience game using the third seat 63. When playing a virtual experience game, as shown in FIG. 11, the second seat 62 is moved on the lower rail 640 to the forward end position, and the front seat cushion 621 is tilted up and down to the folded state. . Furthermore, the display device 20 is attached to the back side of the seat back 623 of the second seat 62. The third seat 63 used for the virtual experience game is arranged in the same manner as in normal use as shown in FIG.

FIG. 12 is a block diagram showing the configuration of a virtual space seat system in Modification 2. The virtual experience seat system 1000D of Modification 2 includes a third seat 63, a remote control 15, a display device 20, and a control device 30. The configurations of the remote control 15, display device 20, and control device 30 are similar to those of the remote control 15, display device 20, and control device 30 shown in FIG. The third seat 63 is provided with pressure sensors PS1 to PS6 and a speaker 130. Pressure sensors PS1 to PS6 are provided on the front seat cushion 631 in the same arrangement as in the case of the seat 10 shown in FIG.

The control device 30 is arranged on a second upper rail 642 to which the third seat 63 is fixed. The control device 30 is connected to a vehicle control device 60 provided on the vehicle side. The vehicle control device 60 drives a motor M provided in the slide mechanism 61 to control sliding movement of the third seat 63 in the front-rear direction.

The operation of the virtual experience game software in Modification 2 is similar to the operation described in FIGS. 3 to 7, but an additional operation is added in which the third seat 63 slides in conjunction with the stepping motion of the seated person. For example, in the case of sliding the foot by 1 cm for each stepping motion, that is, for each step, the control device 30 outputs a command signal to the vehicle control device 60 to move the foot forward by 1 cm for each step. When the slide movement command signal is received, the slide mechanism 60 controls the slide mechanism 61 to move the second upper rail 642 to which the third seat 63 is fixed forward by 1 cm. When the second upper rail 642 reaches the forward end indicated by the broken line due to the moving operation, the second upper rail 642 is returned to the backward end shown in FIG. 11 and then moved forward again according to the number of steps. The landscape image displayed on the display device 20 is the same as in the above-described embodiment, so a description thereof will be omitted.

(Modification 3)
FIG. 13 is a diagram showing the appearance of a virtual experience seat system 1000E in Modification 3. The virtual experience seat system 1000E includes a cushion 80, a control device 30, a display device 20, and a remote control 15. The cushion 80 is provided with pressure sensors PS1 to PS6, and is placed on the seat surface 700 of the chair 70 in the example shown in FIG. Pressure sensors PS1 to PS6 within the cushion 80 are connected to the control device 3 by a harness 800.

Note that in the third modification, the chair 70 is not included in the virtual experience seat system 1000E, and the cushion 80 corresponds to the seat 10 shown in FIG. When playing a virtual experience game, the cushion 80 is used by being spread on a chair as shown in FIG. 13, or on a bench, sofa, vehicle seat, or the like.

FIG. 14 is a block diagram of the virtual experience seat system 1000E. The configurations of the control device 30 and the display device 20 are similar to those of the virtual experience seat system 1000 shown in FIGS. 1 and 2. In the example shown in FIGS. 1 and 2 described above, the seat 10 was provided with the speaker 130, but in the third modification, the speaker 130 is omitted. Furthermore, pressure sensors PS7 and PS8 provided on the armrest 14 of the seat 10 are also omitted. Therefore, it is not possible to enjoy environmental sounds or to move the line of sight from side to side in a landscape image by tapping the pressure sensors PS7 and PS8 with your hands. When the user moves his or her line of sight from side to side, as described in the above embodiment, whether the center of gravity of the user sitting on the cushion 80 is on the left or right side is estimated from the pressure detection values of the pressure sensors PS1 to PS6. If the center of gravity is on the left side, the user shifts the line of sight to the left; conversely, if the center of gravity is on the right side, the user moves the line of sight to the right. The other virtual experience game operations are the same as those described with reference to FIGS. 1 to 7, and their explanation will be omitted.

In the virtual experience seat system 1000E of the third modification, the cushion 80 is used in place of the seat 10 in FIG. 1, so that cost reduction can be achieved. Furthermore, in the virtual experience seat system 1000E, the weight of the entire system is reduced, making it easy to carry. Therefore, as long as you have a power source, you can play virtual experience games anywhere you like.

According to the embodiments and modifications of the present invention described above, the following effects are achieved.

(C1) As shown in FIGS. 1, 2, etc., the virtual experience seat system 1000 includes a seat cushion section 11 provided with pressure sensors PS1 to PS6, which are motion detection sections for detecting motions of a seated person, and A display device 20 displays an image of a landscape seen from the viewpoint of a pedestrian on a walking course, and a viewpoint is moved based on the detection results of pressure sensors PS1 to PS6, and an image based on the viewpoint is displayed on the display device 20. A control device 30 for displaying information is provided. A person seated on the seat cushion portion 11 can enjoy the scenery image displayed on the display device 20 by moving while seated. Since the scenery seen from the viewpoint of the pedestrian walking along the walking course is displayed as a scenery image on the display device 20, it is possible to obtain a realistic feeling as if the pedestrian is actually taking a walk.

(C2) In the above (C1), as shown in FIGS. 1 and 2, the pressure sensors PS1 to PS6 are sensors that detect the pressing force applied to the seat cushion portion 11, and the control device 30 ~ The number of stepping motions of the seated person is estimated based on the change in the pressing force detected by the PS6, and the viewpoint is moved according to the estimated number of times. Since the viewpoint in the video changes depending on the number of times the seated person steps, it is possible to continue the simple stepping motion for a longer period of time without getting bored by enjoying the scenery that changes depending on the movement. becomes. As a result, the exercise effect of the seated person can be improved.

(C3) In (C1) or (C2) above, as shown in FIGS. 1 and 2, the control device 30 further includes a speaker 130, and the control device 30 synchronizes with the video displayed on the display device 20. The corresponding natural environmental sound is generated by the speaker 130. By causing the speaker 130 to generate natural environmental sounds, the seated person can enjoy a more realistic landscape image.

(C4) In (C1) above, as shown in FIGS. 8, 9, etc., the virtual experience seat system 1000A is equipped with a communication unit 31 that exchanges information with another virtual experience seat system 1000B. The information is the position information of the viewpoint on the walking course, and the control device 30 adjusts the image displayed on the display device 20 (display image 200B in FIG. 9) based on the position information received from another virtual experience seat system 1000B.
