Abstract:
A method comprising:recording a plurality of first signals generated by a first channel of a multi-sensor tracking device, wherein the plurality of first signals are generated during a movement of the multi-sensor tracking device, wherein the multi-sensor tracking device comprises a plurality of channels each one of which includes at least one sensor for sensing movement of the at least one sensor with respect to a corresponding axis; recording a plurality of second signals generated by a second channel of the multi-sensor tracking device, wherein the plurality of second signals are generated during the movement of the multi-sensor tracking device, and; calculating a relative phase between the first and second channels, wherein any relative phase is defined as a relative time lag between corresponding signals traveling through a pair of channels, wherein the relative phase between the first and second channels is calculated as a function of at least one of the recorded plurality of first signals and at least one of the recorded plurality of second signals.
