Abstract

An input system for coordinate and pattern includes a pen and a photographic device affixed on the pen, suitable for use on a panel. The photographic device can photograph the panel by a photographic image region and is coupled to a control unit. According to the image pattern of the photographic image region, an image discerning analysis is performed for detecting the coordinate of the photographic image region. The displacement, speed, handwriting, and direction can also be analyzed out. Moreover, the photographic device can photograph the image pattern, and serve as a scanner when the pen moves. The pen can also touch the panel with at least one setting pattern, and exports a keyboard button signal, so as to simulate a keyboard function. The system can also include at least a detection device and a control button for use in operation.
