Magnetic motion capture systems require the real actor to wear a set of sensors, which are capable of measuring their spatial relationship to a centrally located magnetic transmitter. The position and orientation of each sensor is then used to drive an animated character. One problem is the need for synchronizing receivers. The data stream from the receivers to a host computer consists of 3D positions and orientations for each receiver. For human body motion, eleven sensors are generally needed: one on the head, one on each upper arm, one on each hand, one in the center of chest, one on.
