A body motion detector system which combines body exercise with game playing. The body motions are displayed in various forms of challenging games, causing increased user satisfaction in exercise. Body motion is sensed, in a preferred form, by accelerometer transducers mounted on the body. The accelerometer readings are transmitted by radio signals to a base station, a computer, and a display. The receiving station has multiple antennas, as does the transmitting station. The antenna field patterns are analyzed by calculations within the receiver, finding the angular orientation of the body and the body angle of tilt. The computer corrects for errors caused by the effects of gravity on tilted accelerometers. The corrected accelerometer readings are integrated to obtain body motion data.
