A USB Interfaced Motion Capture Sensor, Using Tri-Axis Magnetic/Inertial Sensors For Use In Kinematic Studies

An unobtrusive tri-axis magnetic and gravitational field transducer for use in kinematic tracking is presented. Outlined is a novel approach for using such a sensor i.e. providing a Universal Serial Bus (USB) interface, allowing the direct utilization of the logical topology of the standard, making scalable deployment possible. Furthermore design considerations; construction and performance of the sensor are analysed and discussed in detail.
