MULTI-TOUCH POSITION TRACKING APPARATUS AND INTERACTIVE SYSTEM AND IMAGE PROCESSING METHOD USING THE SAME |
摘要 |
The present invention provides a multi-touch position tracking technique and an interactive system and a multi-touch interactive image processing method using the same. In the present invention, a light guide element is designed to comprise frustrating structures to frustrate total internal reflection (TIR) so that the light beam therein can be dispersed to form a dispersed optical field distribution. The dispersed optical field is used to respond a physical relation between an object and the light guide element.
