Binocularly devised random dot patterns, made popular by computer technology, require the individual to extract a form figure from ground without the help of any monocularly visible contours. As disparity is reduced, however, the subject needs additional help to separate the form of figure from ground, so monocular contour is added. But whether homogeneous or diverse, figure and ground are contiguous with no lateral or vertical distance between them to influence judgment. Although the homogeneous RANDOT test prescribes a “form” response, it is valid if there is perceived only “something” or “nothing” at the proper locations.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eThis test is produced by: Stereo Optical Company, Inc.

This technology also allows for color images to improve interest and images that will resist fading over time. It also has several challenges; the key one being apparent motion. If the test were set up like the traditional polarized version, the answer could have been obtained by even a monocular patient by moving the test from side to side to see which image moves; similar to the apparent motion seen in the polarized type tests by closing one eye at a time. In order to prevent such a hint, this test was designed differently. One image in each row appears to be closer and one appears farther compared to the circle in which they are housed. If the test is moved or twisted from side to side (which they are instructed not to do) one can tell which ones are different, but not whether they come out or go in.\u003c\/p\u003e\n\u003cp\u003eThe test has two test plates: \u003cbr\u003ePlate #1 features a Dinosaur character that tests gross stereopsis.\u003c\/p\u003e\n\u003cp\u003ePlate #2 features clip-art characters that are divided into two separate tests.
