Distance and Depth Perception

Depth or Distance Perception

• Refers to the organization of perception in three dimensions.

• Our mental representation of the world has three-dimensional properties, despite the information projected onto our retina being two-dimensional.

• We use various cues in a visual scene to establish our sense of depth.

Types of Depth Cues

• Binocular Cues: Rely on input from both eyes.

• Monocular Cues: Can be gleaned from the visual input from just one eye.

• Depth perception requires vision.

Monocular Depth Cues

• Depth cues that use information from just a single eye.

• Even with one eye covered, vision still retains some three-dimensionality.

• Able to do things like pick up a pen, move around, and catch a ball.
