Abstract

See full text

A method for adjusting operation of a motion tracking system having a computing device and sensors, wherein each sensor includes a magnetometer, a gyroscope and an accelerometer, includes the following steps: receiving, the computing device, a magnetic field measurement from each of the sensors; digitally processing, the computing device, each of the magnetic field measurements in order to determine if a difference of intensities and/or inclinations of at least one pair of magnetic field measurements exceeds a threshold value, and/or if an x,y point with the differences of intensities and inclinations as coordinates thereof falls outside of a threshold area; and adjusting the operation of the motion tracking system if at least one difference exceeds the threshold value and/or the x,y point falls outside of the threshold area.
