Using a system miniature accelerometers, gyroscopes, and ultrasonic emitters coupled with microphones, researchers at MIT, Mitsubishi Electric Research Laboratory (MERL), and the Swiss Federal Institute of Technology, (ETH Zurich) have developed a motion capture system prototype for about $3000 in parts. The light weight, low power suit uses ultra sonic and inertial sensor data to reconstruct motion and position of not just parts of the body but from the entire body.
