Moving Chair for Virtual Reality

An apparatus called a "personal motion platform" (PMP) is undergoing development for use in adding the sensations of motion to computer-controlled simulated environments of the type now popularly known as virtual reality. The PMP was conceived originally for training an astronaut to interact with surrounding objects in a simulated zero-gravitation environment; it also has obvious potential for use in a variety of applications in biomedical research, education, and entertainment.
