Abstract
A remote control system and method comprising a television and a light pointing apparatus adapted, in a first embodiment, to transmit a first narrow beam having a first frequency corresponding to visible light, which is used to give an indication of where the pointer is pointed, and a second expanded beam surrounding the first beam and comprising a second frequency corresponding to infrared light. In a second embodiment, the pointer transmits a single frequency modulated light beam. In operation, the beam of light is shown on the television screen to activate an on screen menu based user interface via a photo sensor, microprocessor and onscreen display controller. Screen menu items appear on the screen positioned around the periphery of the screen. The user then moves the beam of light on the screen to the periphery of the screen to optically engage one of the plurality of photo conductors, which triggers an appropriate menu sequence or the performance of a television function such as, e.g., channel up.
