ABSTRACT:
A remote control system for controlling a television receiver or the like, which has an operating portion including a diaphragm and at least four light receiving elements. In the remote control system, light issued from an external light source is received by the light receiving elements through the diaphragm. Further, the direction in which the operating portion is oriented is detected on the basis of light receiving signals outputted, by corresponding single electrodes, from each of the light receiving elements. Furthermore, in a unit such as a to be controlled television receiver, a cursor is displayed at a position toward which the operating portion is turned on the screen of the unit. Then, the cursor is moved on the screen in response to change in the direction in which the operating portion is oriented. Subsequently, a desired operation is performed by depressing a switch of the operating portion when the cursor is superposed on an indication of the desired operation in a menu displayed on the screen. Thereby, the remote control system is easily manipulated.
