Abstract
An apparatus including a display; a single pixel detector; and a beam splitter. The beam splitter is located relative to the display and the single pixel detector to allow a projected image from the display to pass through the beam splitter and direct a reflected image from an eye to the single pixel detector, where the reflected image is based at least partially upon the projected image.
