Patent US 6,428,449

An interactive video display and computer system which provides changing video images in response to a combination of signals received from repetitive body movements and voice commands. The system comprises a pace sensing apparatus which is worn on the user's body which senses the repetitive body motion, translates that motion into a signal and transmits the pace signal to a signal receiver, which translates the signal into a signal readily recognized by a computer and then delivers the signal to the computer system. The system further comprises a voice receiving mechanism for receiving voice commands and transmitting a voice signal to the computer system. The user controls the perceived rate of motion and perceived direction of travel, as well as other aspects of the video image, by pace and voice.
