ABSTRACT:
A remote control for controlling a computer using a screen of a television is disclosed. The television receives a video signal from the computer, and a remote control receiver is connecting to the computer. The remote control includes a body member, a light-scope, a photo detector, an electromagnetic emitter, and a mouse button. The light-scope includes a lens system defining a narrow field of view and receives a light signal emitted from an aiming point on the screen of the television as pointed by the light-scope. The photo detector detects the light signal received by the light-scope. The electromagnetic emitter sends back to the remote control receiver a communicating electromagnetic signal communicating the timing that a light signal is emitted from the aiming point. The computer can display a cursor at the aiming point.
