Abstract
To tackle the problems of high cost, low resolution, bulk mass and easily being affected by ambient light of Multi-touch system, a dual-camera multi-touch system was proposed which could achieve human-computer interaction by simply clicking and moving the fingers on the interaction surface. The proposed system detected the input of fingers by two cameras, obtained the positions of Multi-points in two cameras by image processing, and calculated the coordinates in screen coordinate by combining with calibration data, and finally obtained the Multi-points data by tracking the touch points. The experimental results of photo interactive platform show that this system can be used for Multi-touch with good accuracy.
