binocular cues
|
depth cues, such as retinal disparity and convergence, that depend on the use of two eyes

retinal disparity
|
a binocular cue for perceiving depth: By comparing images from the two eyeballs, the brain computes distance-the greater disparity (difference) between teh two images, the closer the object
|
|
|
convergence
|
a binocular cue for percieving depth; the extent to which the eyes converge inward when looking at an object. The greater the inward strain, the closer the object
|
|
|
monocular cues
|
