Abstract
A method for reducing wireless interference and power drain for a wireless input device by not requesting acknowledgements (ACK) for packets containing only displacement data. An acknowledgement is requested after a designated time or number of packets. Each displacement data packet contains all the displacement data since the last ACK to allow easy data recovery. Button clicks and other non-displacement data packets include an ACK request.
