is the change in position of an object on the retina caused by movement of your body relative to the object.

Monocular cue - Motion parallax

Explanation:

When only one eye is used to perceive depth it is known as  Monocular Cues.The various types of cues are as follows: aerial perspective, relative size, interposition, linear perspective, motion parallax and texture gradient.By using such cues artists create more Realistic creation.Motion parallax is a depth cue which takes place from the movement of our body relative to surroundings.Motion parallax makes the object that are closer to you to appear to move faster.The objects that are further away to you to appear to move slower.
