ABSTRACT:
An object of the present invention is to remote control a position of a cursor displayed on a display screen of a reception unit by means of two-dimensional/three-dimensional positioning of a transmission unit. Another object of the present invention is to select a function by operating an ON/OFF switch of the transmission unit.
A light emitted from a light source block of a transmission unit 10 is injected via a first optical block 13. A reception unit 20 receives the light from the transmission unit 10 via a second optical block 21 of a sensor block 22. A detection block 28 detects a light intensity according to an output from this sensor block. A control block 26 calculates a two-dimensional/three-dimensional position of the transmission unit 10 and displays the position as the cursor position on the display screen.
