Abstract
A method for interfacing with a computer through a projected display of the computer using a laser pointer includes processing an image of the projected display captured by a camera, determining position of a laser pointer spot on the projected display, generating commands to position a computer mouse pointer at a screen position corresponding to the projected display, and generating a mouse click for the computer when a programmable laser pointer event occurs. Commands may be used to emulate control of the computer typically provided by a pointing device such as a mouse or track ball.
