Abstract
Simulated shooting at displayed images on the screen of a television receiver using an untethered, simulated gun provides indication on the screen of where the gun was pointed at the time of trigger pull. This is achieved by flashing the screen white subsequent a trigger pull in order that a photosensor within the gun will be responsive to short segments of horizontal raster lines such that by counting vertical lines and time intervals with respect to vertical and horizontal synchronization pulses, respectively, identification of where on the screen the gun was pointing is achieved, permitting a symbol to be displayed upon the screen at that location.
