Depth Perception Overview

Flashcards covering key concepts related to depth perception, including cues, mechanisms, and definitions.

Depth Perception

The ability to perceive the world in three dimensions and to judge the distance of objects.

Monocular Cues

Depth cues that require only one eye to perceive.

Binocular Cues

Depth cues that require the use of both eyes.

Stereopsis

The perception of depth produced by the reception of information from both eyes.

Retinal Disparity

The difference in the images seen by the left and right eye that provides depth information.

Vergence

The simultaneous inward movement of both eyes toward each other to maintain single binocular vision.

Accommodation

The process by which the eye changes its focal length to focus on near or far objects.

Occlusion

A depth cue where closer objects block the view of objects that are further away.

Aerial Perspective

A depth cue created by the effects of the atmosphere on the appearance of objects.

Blur

A cue for depth perception based on the sharpness or fuzziness of an image.

Familiar Size

Using knowledge of the typical size of an object to judge its distance.

Motion Parallax

The difference in the apparent position of an object when viewed from different angles as the observer moves.

Horopter

The imaginary line in space where objects appear to be in the same location in both eyes.

Diplopia

Double vision caused by misalignment of the eyes.

Fusion

The process by which the visual system combines two images into one when both eyes are used.
