A Wall Interactive System Based on Infrared Electronic Pen

In this paper, a new method of interactive system based on infrared electronic pen is proposed to achieve accurate tracking of the target trajectory with anti-jamming ability. Projection technology, infrared sensor, dynamic capture, image processing and other technologies are synthesized in this system. The interactive area is created intelligently and the touch event is determined, and the Improved Mean Shift algorithm is utilized for image information tracking. The simulation of the mouse function can make any wall into a touch screen. With the integration of whiteboard technology, a good human-computer interaction effect can be achieved.
