Abstract

The system of the present invention is to control the displacement of computer cursor based on a laser light spot. It adopts real-time digital image processing to identify the position of the laser light spot within the image display region which is captured by the common conference video camera. Then, the displacement of computer cursor can be controlled according to the successfully detected location of the laser light spot. With the benefit of this preset invention, this system allow users to utilize the laser light spot to control the cursor by indicating the desired points on image display region, which provides greatest convenience to users for giving a presentation.
