PS262 Lecture Notes - Lecture 10: Binocular Disparity, Horopter, Depth Perception
Document Summary
Cues that work with one eye: accommodation: (see above, pictorial cues: sources of depth info in a two-dimensional picture. Occlusion: depth cue in which one object hides or partially hides another object from view, causing the hidden object to be perceived as being farther away. Relative size: when two objects are equal size, the one that is further away will take up less of the eld of view. Perspective convergence: the perception that parallel lines in the distance converge as distance decreases. Familiar size: judgement of distance is based on knowledge of the sizes of objects. Epstein"s coin experiment illustrates the operation of the cue of familiar size by showing that the relative sizes of the coins in uenced perception of the coins distances. Atmospheric perspective: objects that are further away look more blurred and bluer than objects that are closer because we must look through more air and particles to see them.
