Abstract:
1. A method for communicating motion information from a wireless pointer device, the motion information conveyed on a packet data stream and transported on a wireless channel, the method comprising: (a) determining a first count that represents a movement of the wireless pointer device in a first dimension, wherein the first count comprises a first original number of bits; (b) if the first count exceeds a lint threshold, compressing the first count to form a first displacement value, wherein a first compressed number of bits is less than the first original number of bits, and wherein the packet data stream accommodates the motion information; (c) if the first count is not greater than the first threshold, equating the first displacement value to the first count; and (d) transmitting the first displacement value in a data packet over the wireless channel, wherein the data packet is one of a plurality of data packets, and wherein the packet data steam comprises the plurality of data packets.
