Then, the user wears the wearable virtual device and tightly wraps thesafety wrap 14 around the armpit of the user, and the command to be executed is input through the command input terminal element. The data acquisition and processing unit receives the instruction transmitted from the command input end element, processes the instruction and transmits the processed instruction to the audio and video coordination synchronization unit and the motion platform terminal. The scene information database extracts scene conditions. The audio and video coordination synchronization unit extracts corresponding scene conditions from the scene information database according to the instruction transmitted by the data acquisition and processing unit for matching and synchronization, and transmits the synchronized scene information to the wearable virtual equipment. And finally, the wearable virtual equipment receives the synchronized scene information transmitted by the audio and video coordination synchronization unit and displays the scene information to the user. After the user receives the scene information, when the experiencer walks on thesurface cover 8, the sole of the user drives the bearing assembly 9 to freely roll, and the sole slides relative to thesurface cover 8, so that the simulation of relative walking is realized.
When a user carries out simulation training, themotor 6 drives thegear 20 on therotating shaft 21 to rotate, and further drives the rotatingrail 16 to rotate through theteeth 19. Thereby enabling the base 23 on therotating track 16 to follow the rotation of thecamera 7. Thecamera 7 makes a comprehensive view around the user's posture and sends the monitored user posture image to the control unit. The control unit compares the posture image information transmitted by thecamera 7 with the instruction information transmitted by the virtual reality scene terminal, namely whether the user posture in the posture image information meets the standard of the scene state corresponding to the output instruction of the data acquisition and processing unit. And finally, transmitting the comparison result to adisplay screen 3 for display.
Further, thesafety belt 14, thesafety belt 13 and theretractor 10 are provided to prevent a user from falling and being injured when the user receives a teaching. The method specifically comprises the following steps: when the user is dizzy and falls down due to the fact that the user does not adapt to VR technology, thesafety belt 13 is rapidly dropped along with the body of the user, and the speed at the moment is higher than the threshold speed of theretractor 10 for allowing thesafety belt 13 to be pulled. Therefore, theretractor 10 is locked and theseatbelt 13 cannot be paid out. Thereby rendering thesafety wrap 14 incapable of raining and thesafety wrap 14 thereby supporting the user's body from falling. In the process of retracting thesafety belt 13, thesafety belt 13 is guided in a winding manner due to the presence of thebelt guide assembly 12. Thereby preventing thesafety belt 13 from being knotted and turned over in the process of winding and unwinding. And the arrangement of the rotating ball and the steel ball can effectively reduce the friction resistance in the process of retracting thesafety belt 13.
