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.
L'invention est un système de commande et de pointage pour matériel électronique. Le système de l'invention comprend généralement une télécommande tenant dans la main qui comporte un émetteur de signaux infrarouges ayant plusieurs composantes dont chacune est émise à la même fréquence, mais déphasée par rapport aux autres composantes, un récepteur qui comporte un capteur de signaux infrarouges, un circuit connecté à ce capteur de signaux infrarouges qui sert à produire un signal indiquant l'orientation de la télécommande en fonction de l'amplitude de chacune des composantes du signal infrarouge, et un circuit d'interface qui sert à transmettre au matériel électronique un signal de commande représentant le signal d'orientation.
