Abstract :
A system for direct interaction with a video projection screen using a laser pointer is presented. The laser point on the screen is captured by a video camera, and its location recognized by image processing techniques. The behavior of the point is translated into signals sent to the mouse input of the computer causing the same reactions as if they came from the mouse. More complex interaction paradigms are composed from the elementary operations “switch on/off” and pointing of the laser pen
