Abstract
A system and method for operator alignment of a pointing device with a video target display wherein the gun is mounted to be deflected horizontally and vertically for aiming at all portions of the video display includes a first variable device coupled to the gun to provide a varying electric output therefrom in response to horizontal deflection of the gun and a second variable device coupled to the gun to provide a varying electric output in response to vertical deflection of the gun. These outputs control the positioning of an image of a shot on the video display. Each end of the operative range of electric outputs for each variable device is determined by comparing each output successively with each of a series of steps with the gun first pointed to one position of the display and then pointed to another position of the display. This operative range can then be divided equally into a predetermined number of shot positions on the display. In this way a given increment of displacement of the gun within the preestablished operative range can be accurately associated with a related increment of displacement on the display.
