ABSTRACT:
A method and system of detecting objects displayed on a display screen is described. Each object displayed on the screen visually emits a unique identification signal. The identification signal or lack of an identification signal is detected by a detector such as a light pen or video gun and the detector transmits the identification signal on a serial bus to the display screen graphics controller thereby indicating to the controller the position on the screen at which the detector is pointed.
