ABSTRACT:
A survey method and apparatus for monitoring visual observation of a transitionally viewed display. The procedure includes transmitting infrared radiation from behind the display and directed at the path of travel of a moving observer. A radiation detector receives reflected radiation and generates a thermal image corresponding to radiance variations. Retinal eye reflection from the observer is readily distinguishable in the thermal image and provides a positive indication that the observer's line of sight is vectored upon the display.
