Abstract :
We have developed a low-cost force output device as a user interface and combine it with an MPEG-1 video player to form a virtual reality system for entertainment. We designed a motor-powered motion chair to create the sensation of being carried in an airplane or a vehicle. To obtain smooth motion, curve fitting and filtering on the motion trajectory are used. The synchronization of video and motion chair is solved with the techniques of motion prediction, while combined with a joystick provides a way for interactive games
