What Is an Ames Room?

An Ames room is a distorted room that creates an optical illusion. It was invented in 1946 by Adelbert Ames.

It lets one person on one side appear much taller than the other on the opposite side.

How Does the Ames Room Illusion Work?

Time to explain the Ames room illusion:

The Ames room looks like an ordinary cubic-shaped room to the viewer but that is not true. In fact, the true shape is trapezoidal. One corner of the Ames room is closer to the observer in the front than the other. Also, the floor and ceiling are at the incline and the walls are slanted.

That leads the viewer to believe that two people standing in the same depth of the field but one looks like a giant and the other like a dwarf. But in truth, this visual illusion is only caused by the optical illusion room and one person is standing much closer than the other.
