Abstract
An image processing system enables the manipulation of individual anonymous laser pointers in interactive visual games. The system includes a display system that displays an image on a display screen. A camera acquires a sequence of images of the display screen. Participants in the game aim individual laser pointers at the screen; the laser pointers form dots on the display screen. A warp module corrects the acquired images for distortion. A registration module registers the corrected sequence of images with the displayed image, and modifies the displayed image in response to a distribution of the laser dots on the display screen.
