The setup system consists of a computer connected to a projector and a webcam aimed at the presentation screen. The camera is used to detect the position of the pointing device (laser dot) on the screen, allowing the laser pointer to emulate the actions of a mouse such as moving the mouse pointer, clicking, scrolling etc. So the users need not remain near the computer, but can directly use laser pointer at a distance. Requires MATLAB 2012a(ver 7.14)
