Abstract
A wireless control and pointer system for controlling electronic equipment. The system generally includes a hand held remote control comprising a first infrared signal emitter for use in transmitting a first infrared signal comprising a plurality of signal components each of which is transmitted at a first frequency but out of phase with respect to the other of the plurality of signal components and a receiver comprising an infrared signal sensor adapted to receive the infrared signal, a circuit connected to the infrared signal sensor for generating an orientation signal indicative of the orientation of the remote control as a function of the amplitude of each of the plurality of signal components of the infrared signal, and an interface circuit for transmitting a command signal indicative of the orientation signal to the electronic equipment.
