Abstract
A remote control device for a television receiver or the like includes a housing that defines a cavity. IR emitter-detector pairs are arranged about the cavity to establish an x-y pattern of IR beams within the cavity. Interruption of the IR beams by an opaque object, such as a human finger, activates signal generating means for generating control signals.
