Monocular Cues

Monocular Cues

Monocular cues are part of the depth-perception ability to sense the distance of an object; these cues are monocular because they can be sensed with just one eye.

Motion Parallax

In motion parallax, with perception through motion, objects that are closer seem to move faster than objects that are further away

    

The mountains in the background appear to be moving very slowly compared to the ground in the front.

Linear Perspective

In linear perspective, parallel lines seem to meet as they travel together to a distance.

The railroad tracks appear to converge in the distance although they are actually parallel.
