As described above, the first fixing section 140 winds up the first belt 145 in conjunction with the motion of the subject 200 . As a result, the subject 200 is in an inverted state. That is, the subject 200 can experience the same experience as bungee jumping in real space.

In addition, since the target person 200 can visually experience bungee jumping in the virtual space when the target person 200 actively falls down, the immersive feeling of the target person 200 is not hindered.

(Second embodiment)
8(A) to 8(C) are cross-sectional views showing the operation of the cart of the simulated experience device according to the second embodiment of the present invention.

The second embodiment differs from the first embodiment in that illuminance sensors 160A, 160B, and 160C are arranged on rail 120A. Other points are the same as those of the first embodiment, and the description of the same portions will be omitted.

The subject 200 performs an action of falling from the position of the support X1 toward the support X2 (Y-axis direction). At this time, the trolley 130 moves along the Y-axis direction by rotating the tires 135 provided on the trolley 130 .

At this time, as the subject 200 moves, the cart 130 moves with the acceleration G0.

As shown in FIG. 9(B), the truck 130 moves in the Y-axis direction so that the truck 130 operates with an acceleration G1.

Ultimately, as shown in FIG. 9C, the right end of the truck 130 in the Y-axis direction reaches the column X2. At this time, the carriage 130 moves with the acceleration G2.

By configuring in this way, the control section (not shown) controls the winding section of the first fixing section 140 based on the values of the accelerations G0, G1, and G2. That is, the first fixing portion 140 winds up the first belt 145 based on the acceleration of the carriage 130 .

The acceleration sensor 165 can communicate with the first fixed portion 140 . Also, the first fixing unit 140 can communicate with a control unit (not shown). By configuring in this way, the control unit transmits information based on the result received from the acceleration sensor 165 to the VR device 250 and changes the scene image. Further, the control section may control the winding section of the first fixing section 140 so that the first fixing section 140 winds up the first belt 145 . In this case, it is preferable that the hoisting section has a motor, and the control section controls the motor.

Even with such a configuration, the first belt 145 is wound up according to the motion of the subject 200, and the subject 200 is in an inverted state. That is, the subject 200 can experience the same experience as bungee jumping in real space.

In addition, since the target person 200 can experience bungee jumping in the virtual space with the motion of actively falling down as a trigger, the target person 200 is not hindered from feeling immersed.

In the above configuration, the control unit controls the first fixing unit 140 based on the values of the accelerations G0, G1, G2. However, the control section may be configured to control the first fixing section 140 according to the displacement from the acceleration G0 to the acceleration G1 or from the acceleration G1 to the acceleration G2. Also, the control unit may be configured to perform control according to the moving speed of the truck instead of the acceleration.

In addition, the simulated experience device may have a configuration that stimulates the subject's five senses including sight (wind, smell, sound, etc.) in order to give the subject a sense of reality.
