Abstract
A method and system for detecting objects displayed on a display screen is described. Each object displayed on the screen visually emits a unique identification signal in the form of a color signal having multiple color components. The relative peak amplitude of each color component in the color signal is detected by sampling the color signal with photo-sensors corresponding to each color component. The sampled color components are digitized and transmitted to the display screen graphics controller thereby indicating to the controller the object on the screen at which the detector is pointed.
