Development of multipurpose virtual-reality dynamic simulator with a force-reflection joystick

The objective of this paper is to develop a multipurpose virtual-reality (VR) dynamic simulation system to meet the requirements of public security in the training of human operators. In this way, the operator can feel that he or she is controlling a real machine or vehicle to achieve the objective of real training. The developed VR dynamical simulation system in this paper mainly consists of three elements: a six-degree-of-freedom motion platform (Stewart platform), a force-reflection joystick, and an interactive VR scene. In the developed VR dynamic simulation system, the operator could sit on a Stewart platform to feel the velocity and orientation of motion, and could handle a force-reflection joystick to transfer the commands to the VR scene. Then, the operator will receive the force feedback from the Stewart platform and the joystick. Finally, a flight simulation scene is applied to illustrate the effectiveness of the developed VR dynamical simulation system. Experimental results demonstrate that the evaluation of the VR dynamical simulation system is comparatively good.
