Abstract
There is provided a hand held cursor controller system for use particularly with interactive television and computer presentation graphics. The system uses a hand held device with infrared light emitting diodes which transmits to a detector attached to a processor. The information from the processor is transmitted to a television or video cassette recorder. The system allows for the positioning of a cursor on a television screen with the only input of the user being the aiming of the controller. It includes push-button activation and provides for the transmission of the usual controller codes.
