Shaurya Sinha – Final Project

For my final project, I wanted to create an optical illusion model that could be used by Dr. Przybyla, and other psychology professors, to demonstrate the effects of misperception. I chose to design an ames room, a distorted room that appears cubic when monocularly (with one eye), from a specific viewpoint, even though the room is actually trapezoidal. Additionally, objects in the room tend to appear as if shrinking or growing when moving from one corner to the other.

 

Here is an example of this effect demonstrated by infamous Dr. Philip Zimbardo:

 

Designing this room came as quite the challenge, as the specific distortion of the room shape need to achieve the effect from a specific viewing point was not only a mathematical process of deduction, but also turned out to be quite complicated when designing in Fusion 360.

To do this I initially created a mock sketch of a regular cubic room, and extrapolated construction axis along the corners of the room.

Then I connected points along specific axis that would act as a projection of the cubic room into a trapezoidal form.

I then proceeded to construct along this projected sketch, resulting in the following:

As a result, when viewing from the center of the frame, the room appears cubic, while subjects within the room at different corners appear to be changing sizes.
