  • Publication number: 20160070419
    Abstract: A touch input system includes a touch surface, a reflective structure, and a touch-position generating device. The reflective structure is disposed to surround the touch surface and protrude out the touch surface. The touch-position generating device includes a pen-like body, a lighting and receiving module disposed in the pen-like body, and a processing module. The lighting and receiving module and the processing module are connected in communication. When the touch input system is in operation, the lighting and receiving module emits light toward the reflective structure and receives the light that is reflected by the reflective structure relative to the touch surface. Then, the processing module determines a touch position of the pen-like body on the touch surface according to the received light. Thereby, the touch-position generating device can perform the determination of the touch position independently from the operation of a touch panel or device providing the touch surface.
