A Real Time Motion Capture System, using USB Based Tri-Axis Magnetic and Inertial Sensors, for Movement Based Relaxation

A scalable motion capture system based on multiple orientation sensors, each consisting of tri-axis magnetic and gravitational field transducers, for use in kinematic studies; is presented. Outlined is a novel system capable of accessing real time data from multiple sensors, via one universal serial bus host, using a dynamic link library. In addition, design considerations; implementation and performance of the system are analyzed and discussed.
