Abstract
Visual images in proper perspective are optically displayed to each eye of one or more movable observers through a common display system. Real images of aperture stop pupils continuously track their respective eyepoints when the eyepoints change location. Each of the individual images as confined by their respective real pupil images are viewed at their corresponding eyepoints without optical interference.
