A "light pen" is clamped to the muzzle of a weapon. The "light pen" and weapon are aimed at a microcomputer-generated target or videodisc-player-generated target on the screen of a television monitor. A trigger switch on the weapon is closed when the marksman perceives the correct orientation between the weapon and the target. The microcomputer calculates the proper trajectory of the simulated "round" based on the orientation of the "light pen" relative to the screen at the time the trigger switch is closed in order to generate and display the calculated shot impact point for the benefit of the trainee marksman. | |
