Abstract:
     The present invention relates to a directional wireless input device and its safety input system using said device. It is characterized by that said invention utilizes a light-emitting mode of a directional wireless input device whose light-emitting cross-section is less than its projection distance and modulates said light-emitting mode to make its emitted light beam can be identified by a detection device when said light-emitting mode is directed to the detection device and emits light, so that when several users respectively hold input devices with different light-emitting modes, said system can identify the identity of every user by means of different light-emitting modes so as to form the invented safety input system.
