“…Unlike binocular vision, monocular (mono=one, ocular=eye) vision does not require the use of both eyes (see Benson, 1999;Bond et al, 1962;Green, 1988;Kershner, 1 98 1 ;Langewiesche, 1972;Peter, 1999;Reinhart, 1996;Reinhardt-Rutland, 1997;Riordan, 1974;Tredici, 1996), and generates depth perception fiom a two-dimensional environment (Hawkiis, 1993; for an example see Nagel, 1988). The ability to generate depth perception fiom a two dimensional environment depends on perceptual cues which we will refer to as "monocular cues".…”
