Claim:
1. A wireless unit, comprising: a motion sensor; a transceiver configured to receive wireless communications; and at least one processing device configured to respond to reception of motion information by the transceiver by sampling an output of the motion sensor and comparing the sampled output with received motion information, wherein the received motion information comprises at least one received motion vector having x, y and z components corresponding to three orthogonal directions and the sampled output of the motion sensor comprises at least one sampled motion vector having x, y and z components corresponding to three orthogonal directions, and said processing device is configured to perform the comparison by determining a correction vector between one of said received motion vectors and one of said sampled motion vectors and correcting a subsequent one of said received motion vectors and said sampled motion vectors based on said correction vector prior to using the subsequent motion vector during said comparison.
