Document Summary

Forced perspective: an optical illusion that makes objects appear further away, closer, smaller, or larger than they actually are, manipulates a variety of depth and size cues used by the visual system for perception. Cue theory of depth perception: although the world is three dimensional (3d) the image on the retina is a 2d representation, the visual system relies on many learned cues to perceive depth. Oculomotor: cues based on our ability to sense the position of our eyes and the tension in our eye muscles. Monocular: cues that work with one eye. Binocular: cues that depend on two eyes: the association becomes automatic through repeated exposure (may not be born w/cues) Relies on sensing the position of our eyes and muscle tension: 1. Eyes move inward to focus on objects that are moving closer: 2. Lens shape adjusted depending on distance of object.
