<p>PURPOSE: A touch input system is provided to enable a touch pen to acquire coordinates touched at a touch panel by detecting reflection light by sensing the movement of the ball through a light emitting unit and a light reception unit. CONSTITUTION: A touch pen(300) acquires a coordinate touched at a touch panel by detecting the movement of a ball(320), the surface of the touch panel, or light reflected from the surface of the touch panel. A light emitting unit emits light to the surface of the touch panel. A light reception unit(330) receives light reflected form the surface of the touch panel. The ball is installed the end of the touch pen.</p> |
