binocular depth cue

Brain perceives depth using scene points that stimulate right and left eyes differently {binocular depth cue} {binocular depth perception}. Eye convergences, retinal disparities, and surface-area sizes have differences.

surface area size

Brain can judge distance by overlap, total scene area, and area-change rate. Looking at surfaces, eyes see semicircles. See Figure 1. Front edge is semicircle diameter, and vision field above that line is semicircle half-circumference. For two eyes, semicircles overlap in middle. Closer surfaces make overlap less, and farther surfaces make overlap more. Total scene surface area is more for farther surfaces and less for closer surfaces. Movement changes perceived area at rate that depends on distance. Closer objects have faster rates, and farther objects have slower rates.
