Adelbert Ames Room Research Paper

How was Ames room invented?. In 1946 it was discovered by adelbert ames jr.who first constructed such a room wich he got the materials in around the 19th centaury. There are two illusions in this room. There is where it seems to be that he room is squared…and the other where one person seems to shrink at a tremendous rate but still standing at the same distance. How is that possible?

When you look into an ames room (through the peephole) everything seems to be normal and cubic. But in reality everything is actually trapeziodal shaped from the window, wall, floor , and even though the floor appears leveled it can actually be an inclined floor. The wall appears perpendicular to the floor but is actually slanted outwards. This is how it all puts into play. When the light appears from on corner of the cube then
The person looks small because the image is smaller than what would be expected for the actual distance of that part of the room. The illusion is so convincing that as the person is seen walking about the room, he or she appears to be growing and shrinking. In the Ames Room, the person appears to travel along an apparently horizontal and level surface. There is no observed rise in relation to the horizon as the figure recedes. This is important, because a figure receding on a level surface will rise in the visual field, given the fixed relative position of the viewer and the figure.On a level surface as someone recedes into the distance the level of their feet rise and the level of their head lowers in relation to a true horizontal. While the additional apparent lines are several factors increasing the illusion, their main reason is to hide correct cues, not to create the illusion. In addition, the perspective cue of relative head height is not significant, compared to ground
