Wireless cursor remote control for multi-media system

摘要

A hand-held unit emits light-signals in the form of geometric images and/or geometric signal images which are shifted according to the movement executed with the handheld unit. The signal image and its shift is received by a receiver, is analysed, and is converted in a signal processing device into a cursor movement to be executed. The geometric images and/or geometric signal images emitted by the handheld unit are produced through corresp design of a light or signal source.
