Image Number 2 for United States Patent #4303394.
A computer generated image simulator is disclosed for scanning a visual target and then providing a visual image of the target which is to be displayed upon a reflective display screen such that a trainee pilot may observe the target. A head tracker which monitors the position of the trainee pilot's head, and an eye tracker which monitors the position of the trainee pilot's eyes, respectively provide head and eye orientation signals to be processed by electronic circuitry such that the target which is projected upon the reflective display screen by a helmet mounted projector will be orientated upon the screen in accordance with the orientation of the trainee pilot's head.
