is an important depth cue that comes into play during head movements or while moving through an environment.

Motion parallax.

Explanation:Motion parallax is a trick of the eyes that comes into play when object closer to us seems to be moving quickly making the objects look as if they are farther away from us.

When we intentionally make head movement,motion parallax makes makes objects bigger.

Motion parallax

Explanation:

Motion parallax is simply defined as that monocular depth cue that emanates as a result of the relative velocities of moving objects across the retinae of a person who is in motion. Parallax, as the term implies means "position change". Thus, we can say that motion parallax is simply a position change that is caused by the movement of the individual or person who is viewing.
