Abstract
When near and far objects in two-dimensional images, are carefully aligned so that they appear to be interacting with each other, misperceived distance can lead to misperception of object size. This technique is usually referred to as forced perspective. We studied the depth perception of a small sample of college students who viewed forced perspective images and were asked to make judgements of size or the distance of objects. Some of the factors we examined included: familiar size, relative size, distance, knowledge of the metric system, binocular vision related symptoms, and the action and reactions in the pictures. Preliminary analysis showed that most participants were able to make accurate judgements of absolute size and distance, but not when asked to make comparisons of the relative size of two objects. Relative size seems to be one of the most compelling cues creating forced perspective images. Future work will include correlational analysis that can capture the relationship and strength of the each of the factors in this study.
