A customized add-on with MEMS gyroscopes and magnetic field sensors was created for the Nintendo(TM) Wii Remote Controller to produce a oneto- one mapping in orientation estimation. Advanced nonlinear Kalman filtering methods were used for the fusion of the signals from low performance inertial and magnetic sensors. The estimated orientation is employed for correction of relative position estimation based on markers from the IR camera image. The estimated 6DOF are sent via Bluetooth in real-time to COVISE visualization system running on the host computer.…
