Ames Room Research Paper
Ames Room
An “Ames Room” is a distorted room that is used to create an optical illusion of relative sizes. It was invented by American ophthalmologist Adelbert Ames, Jr. The first Ames room was built in 1946, based on the late nineteenth century concept of German scientist Hermann von Helmoltz.
As a result of the optical illusion created by the distorted room, a person standing in one corner appears to the observer to be significantly larger than a person standing in the opposite corner while the room appears to be a normal rectangular shape. This is taken to indicate the significant role past experience has on our interpretation of our perceived world.
Description: Upon viewing people or objects within an Ames room, there is a loss of normal perspective. As a result of the optical illusion created by the distorted room, a person standing in one corner appears to the observer to be significantly larger than a person standing in the opposite corner. The illusion is convincing enough that a person walking back and forth from the left corner to the right corner appears to grow or shrink, and balls appear to roll uphill. …show more content…
Explanation: An Ames room is constructed so that, from the font, it appears to be an ordinary rectangular room, with a back wall and two parallel side walls perpendicular to the horizontally level floor and ceiling.
In reality, this rectangular appearance is a trick of perspective. The true shape of the room is trapezoidal: the walls are slanted and the ceiling and floor are at an incline, and the right corner is much closer to the front-positioned observer than the left corner (or vice versa). Observers look through a peephole into the room to create the best viewpoint and remove any sense of depth created by viewing the room with both eyes. The illusion is often enhanced by adding additional visual perspective clues, such as a checkered floor and “rectangular” windows on the back
wall.
There is nothing surprising in our perception of the empty room as normal, for the image we see through the peephole is identical to that which would be received from a normal rectangular room. However, when people stand in the room there is a conflict. The person in the further corner has a smaller image, due to their greater distance from the observer as compared to a person in the nearer corner. What is surprising is that observers see the people distorted in size and the room retains its rectangular shape, presumably because we are used to seeing rectangular not trapezoidal rooms. Ames and subsequent researchers used this phenomenon to demonstrate the importance of experience in perception.
Interestingly enough, an entire room is not necessary to create the illusion of distorted size; it is sufficient to create an apparent horizon against an appropriate background. The eye then relies on the apparent relative height of an object above that horizon.
