1. A method of detecting objects on a display screen having an associated controller comprising the steps of:
- causing each of a plurality of said objects to visually emit an unique object identification signal on said screen;
detecting at least one of said object identification signals emitted from said screen corresponding to at least one of said objects;
providing to said controller said at least one object identification signal;
identifying said at least one object on said screen with said unique object identification signal using said controller.

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.

11. A system for detecting objects on a screen comprising:
-
a display screen for displaying objects; a display system controller for causing each of a plurality of said objects to visually emit an unique object identification signal corresponding to each of said plurality of objects from said screen for at least a portion of the time said plurality of objects are displayed; a detector for detecting at least one of said object identification signals and providing to said controller said at least one of said object identification signals; said display system controller utilizing said at least one of said object identification signals to identify at least one of said plurality of said objects on said screen. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
