Abstract
A method for adjusting operation of a motion tracking system at least including first and second sensors and a computing device, each of the sensors at least having a gyroscope. The method includes the following steps: arranging the first sensor on an upper arm of a person, and the second sensor on their chest; measuring orientations each of the first and second sensors while the person performs a predetermined movement. The movement includes the person moving a torso with respect to their hip while keeping the upper arm parallel to the torso and not rotating the upper arm. The method further includes digitally processing, the computing device, the orientations measured so as to digitally compute an orientation difference between the orientations measured by the first sensor and by the second sensor; and adjusting, the computing device, the operation of the motion tracking system based on the orientation difference computed.
