Parallax

Parallax (from the Greek. parallaxis – evasion) – change in the apparent position of any of the object relative to a background when you change viewing angle.

This concept is used in many fields, particularly in astronomy and photography. In psychology there is the concept of "monocular motion parallax" – that is, the monocular visual sign remoteness of an object. Based on his dependence of the angular velocity of the displacement of objects from their egocentric distance in the motion of the observer relative to these objects with constant velocity.

A clear example is how people while traveling in the train or the car, considering the landscape from the window. Which is closer to the observer moves faster than the more remote. If you look at any object, it turns out that all visible space revolves around this subject.
