Abstract
Abstract By using a viewing device and the proper configuration of visual stimulus material, one can create competition between the two eyes and determine what is perceived by a binocular observer. Where one eye sees light or pattern in a zone of the visual field, surrounded by a dark boundary, and the other eye sees stimulus material which does not have such a boundary, the material which is contained within the dark boundary will dominate the binocular perception. With some stimulus configurations the observer will see a bright, "lustrous" form which appears to float slightly above the stimulus surface. In other cases patterns presented to each eye will be dissected and combined into a composite perception which is determined by the presence of the dark boundary. Applications for the invention include testing of patients for impairment of vision and producing special effects in movies and other forms of entertainment.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
165 words
An arrangement of viewing conditions and a configuration of visual stimulus elements for presentation to and for controlling the perceptions of a binocular observer, comprising: (a) means for presenting separate visual images to the respective eyes of said observer, each of said visual images being formed by a collection of elements, (b) means for controlling the color and brightness of said elements, (c) said means for presenting and said means for controlling further providing one of said eyes with a set of black elements that surround and contain a zone of the images presented to said one eye, thus forming a black border around said zone of said image, without providing such black border around the corresponding zone in the image presented to the other of said eyes, such that the portion of the image in said zone contained by said black border will dominate perception across the corresponding zone of said observer's binocular perception, and will have uniformity of dominance across said perceptual zone.
Claim 2
Dependent Claim
165 words
An arrangement of viewing conditions and a configuration of visual stimulus elements for presentation to and for controlling the perceptions of a binocular observer, comprising: (a) means for presenting separate visual images to the respective eyes of said observer, each of said visual images being formed by a collection of elements, (b) means for controlling the color and brightness of said elements, (c) said means for presenting and said means for controlling further providing one of said eyes with a set of black elements that surround and contain a zone of the images presented to said one eye, thus forming a black border around said zone of said image, without providing such black border around the corresponding zone in the image presented to the other of said eyes, such that the portion of the image in said zone contained by said black border will dominate perception across the corresponding zone of said observer's binocular perception, and will have uniformity of dominance across said perceptual zone.
Claim 3
Dependent Claim
70 words
The arrangement of claim 1 wherein said means for presenting and said means for controlling also are arranged to provide bright image elements within said image zone contained by said black border in one said eye, and black image elements in the corresponding image zone of said other eye, such that said observer's binocular perception is of a stimulus having a uniform bright, lustrous quality across said corresponding perceptual zone.
Claim 4
Dependent Claim
107 words
The arrangement of claim 1 wherein said means for presenting and said means for controlling also are arranged to provide each of said eyes with a different pattern of image elements across extended and overlapping image zones, with said black border serving to divide the image zone of one said eye into a plurality of subzones which lie inside and outside said border, such that the pattern presented to the image subzone, which lies inside said border will dominate said observer s binocular perception within the corresponding perceptual subzone, and the pattern seen by said other eye will dominate the perceptual subzone which lies outside said border.
Claim 5
Dependent Claim
35 words
The arrangement of claim 1 wherein said means for presenting visual images comprises a plurality of color filters and means for interposing such filters between said eyes and the respective images presented to said eyes.
Claim 6
Dependent Claim
37 words
The arrangement of claim 2 wherein said means for presenting visual images includes means for projecting said images upon a viewing surface using polarized light, and means for interposing polarized filters between said images and said eyes.
Claim 7
Dependent Claim
22 words
The arrangement of claim 2 wherein said means for presenting visual images comprises a stereoscope for providing said eyes with said images.
Claim 8
Dependent Claim
37 words
The arrangement of claim 1 wherein said means for controlling said color and brightness of said elements further includes means for varying the thickness of said border, and for modifying and evaluating the degree of said dominance.
Claim 9
Dependent Claim
45 words
The arrangement of claim 2 wherein said means for controlling said color and brightness of said elements further includes means for varying the position of said border in relation to the fixation point of each of said eyes, and for evaluating said uniformity of dominance.
Claim 10
Dependent Claim
38 words
The arrangement of claim 2 wherein said means for controlling said color and brightness of said elements further includes means for varying the size of said zone contained by said border, and for evaluating said uniformity of dominance.
Claim 11
Dependent Claim
38 words
The arrangement of claim 1 wherein said means for controlling said color and brightness of said elements further includes means for varying the shape of the zone contained by said border, and for evaluating said uniformity of dominance.
Claim 12
Dependent Claim
46 words
The arrangement of claim 1 wherein said means for controlling said color and brightness of said elements further includes means for providing a binocular mixture of color elements within the zone contained by said border, and for evaluating said uniformity of dominance produced by said mixture.
Claim 13
Dependent Claim

The arrangement of claim 2 wherein said means for presenting said images comprises a stereoscope for providing the respective eyes with said images, and said means for controlling said brightness comprises a plurality of polarizing filters.
