Depth Perception

Depth Perception

The ability to see in three dimensions and to judge distance.

Visual Cliff

Laboratory device for testing depth perception in infants and young animals

Binocular Cues

Depth cue requiring the use of both eyes

Monocular Cues

Depth cue requiring the use of a single eye

Retinal Disparity

Binocular depth cue which results from the different images produced by the slightly different images produced by the retina of your left eye and the retina of your right eye.

Convergence

Binocular depth cue which translates tension in the eye muscles when the eyes track inward to focus on objects close to the viewer.

Relative Size

Monocular depth cue where an object of known size appears larger when close and smaller when far.

Relative Motion

Monocular depth cue where perceived slowness indicates an object is distant.

Interposition

Monocular depth cue where closer objects partially obstruct the view of more distant objects.

Relative height

Monocular depth cue where distant objects appear relatively higher in your field of vision than close objects.

Texture Gradient

Monocular depth cue where distant objects have a smoother texture than nearby objects.

Relative Clarity

Monocular depth cue where distant objects are less clear than nearby objects.

Linear Perspective

Monocular depth cue where parallel lines seem to draw together in the distance.
