Abstract
Abstract Stereoscopic patterns are disclosed which have a multiplicity of representations on a backing, with the representations spaced apart in substantially horizontal rows. The spacing between pairs of adjacent representations is varied to produce a stereoscopic effect. The resulting pattern is continuous, eliminating the ghost images associated with prior art stereoscopic pictures. The representations may be identical, may be varied shapes formed of identical elements, or may be a sequential series of perspective views of the same subject. The patterns may be viewed stereoscopically in either of two manners: by diverging or straightening one's line of vision while holding the pattern relatively close, or by converging or crossing one's line of vision while holding the pattern relatively far away. When viewed in the first manner, the patterns simulate distance vision while being held close-up, providing relaxing viewing to the eyes of one engaged in close work.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
187 words
A pattern capable of being viewed to produce a stereoscopic effect, which comprises: a blank backing, and a multiplicity of representations on said backing spaced apart in substantially horizontal rows, each of the representations in each horizontal row being substantially identical, an adjacent pair of said representations when viewed stereoscopically producing a first stereoscopic image and two ghost images, another of said representations located on said backing in a position in which the image produced by stereoscopically viewing said other representation combines with one of said ghost images produced by one of said adjacent pair of representations to produce second stereoscopic image, the remainder of said multiplicity of representations located on said backing in positions in which the images produced by each of said representations combine with ghost images produced by other representations to produce additional stereoscopic images, the spacing between various pairs of adjacent representations in each horizontal row being varied to produce a plurality of horizontally spaced stereoscopic images perceived in various planes from said pairs of adjacent representations, said backing being devoid of any marking other than said representations to avoid producing distracting images.
Claim 2
Dependent Claim
187 words
A pattern capable of being viewed to produce a stereoscopic effect, which comprises: a blank backing, and a multiplicity of representations on said backing spaced apart in substantially horizontal rows, each of the representations in each horizontal row being substantially identical, an adjacent pair of said representations when viewed stereoscopically producing a first stereoscopic image and two ghost images, another of said representations located on said backing in a position in which the image produced by stereoscopically viewing said other representation combines with one of said ghost images produced by one of said adjacent pair of representations to produce second stereoscopic image, the remainder of said multiplicity of representations located on said backing in positions in which the images produced by each of said representations combine with ghost images produced by other representations to produce additional stereoscopic images, the spacing between various pairs of adjacent representations in each horizontal row being varied to produce a plurality of horizontally spaced stereoscopic images perceived in various planes from said pairs of adjacent representations, said backing being devoid of any marking other than said representations to avoid producing distracting images.

Dependent Claim
14 words
A pattern as in claim 1, in which each of said representations is identical.
Claim 4
Dependent Claim
17 words
A pattern as in claim 1, in which said representations form a multiplicity of horizontally-spaced generally-vertical lines.
Claim 5
Dependent Claim
16 words
A pattern as in claim 3, in which said lines are combined to define varying shapes.
Claim 6
Dependent Claim
23 words
A pattern as in claim 1, in which said multiplicity of representations are a sequential series of perspective views of the same subject.
Claim 7
Dependent Claim
34 words
A pattern as in claim 1, in which the multiplicity of representations on said backing is spaced apart in substantially horizontal rows with each adjacent pair of representations having different spacing between each other.
Claim 8
Dependent Claim
32 words
A pattern as in claim 1 for viewing with a straight or diverging line of vision, in which the spacing between the various pairs of adjacent representations does not exceed 23/8 inches.
Claim 9
Dependent Claim
49 words
A pattern as in claim 1 for viewing with a converging line of vision, comprising in addition means for providing a physical reference in the planes in which said stereoscopic images appear, said means comprising a reference mounted around and located a substantial distance in front of said backing.
Claim 10
Dependent Claim
71 words
A pattern as in claim 1, in which said multiplicity of representations comprises: a plurality of identical first representations on said backing spaced apart in a substantially horizontal first row, and a plurality of identical second representations on said backing spaced apart in a substantially horizontal second row, which is substantially parallel to said first row, the spacing between said second representations being different from the spacing between said first representations.
Claim 11
Dependent Claim
117 words
A pattern capable of being viewed to produce a stereoscopic effect, which comprises: a backing layer; a movable transparent overlay horizontally slidably mounted over said backing layer; and a multiplicity of representations, some of which are on said backing layer and the remainder of which are on said overlay, the representations being spaced apart in substantially horizontal rows, each of the representations in each horizontal row being substantially identical, the spacing between various pairs of adjacent representations being varied to produce a plurality of horizontally spaced stereoscopic images from said pairs of adjacent representations, the movement of said overlay producing a movement of some of said images in a direction perpendicular to the plane of the overlay.
Claim 12
Dependent Claim
117 words
A pattern capable of being viewed to produce a stereoscopic effect, which comprises: a backing layer; a movable transparent overlay horizontally slidably mounted over said backing layer; and a multiplicity of representations, some of which are on said backing layer and the remainder of which are on said overlay, the representations being spaced apart in substantially horizontal rows, each of the representations in each horizontal row being substantially identical, the spacing between various pairs of adjacent representations being varied to produce a plurality of horizontally spaced stereoscopic images from said pairs of adjacent representations, the movement of said overlay producing a movement of some of said images in a direction perpendicular to the plane of the overlay.
