Abstract
Abstract An apparatus and method for displaying and viewing full field-of-vision stereoscopic images is disclosed. The apparatus includes left and right display components including curved screens. The screens are suitable for mounting in a fixed position relative to the viewer's head and close to the viewer's eyes. The screens provide the normal single-eye full field of vision of 120° vertically and 180° horizontally. Each screen has a spherical central surface and a cylindrical temporal surface that extends from the central surface along the side of the viewer's head. The screens are mounted close to the viewer's eyes and optical components are provided to cause the viewer's eye to be focused at the central surface. Contact lenses are suitable optical components. Contact lenses do not limit the viewer's field of vision and are continually oriented with the movements of the viewer's eyes.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
108 words
Apparatus for the viewing of stereoscopic images by a viewer, the apparatus being used in conjunction with contact lenses that cause the viewer's eyes to be closely focused, comprising: image display means including means for receiving signals representative of left and right images, left and right concave display surfaces, each surface having a display center, and means for displaying said left and right images on said display surfaces; and mounting means for closely mounting said display surfaces at fixed positions relative to the viewer's head such that the viewer's centerlines of vision are aligned with said display centers, whereby the viewer's eyes are focused on said display surfaces.
Claim 2
Dependent Claim
108 words
Apparatus for the viewing of stereoscopic images by a viewer, the apparatus being used in conjunction with contact lenses that cause the viewer's eyes to be closely focused, comprising: image display means including means for receiving signals representative of left and right images, left and right concave display surfaces, each surface having a display center, and means for displaying said left and right images on said display surfaces; and mounting means for closely mounting said display surfaces at fixed positions relative to the viewer's head such that the viewer's centerlines of vision are aligned with said display centers, whereby the viewer's eyes are focused on said display surfaces.
Claim 3
Dependent Claim
84 words
The apparatus for the viewing of stereoscopic images as claimed in claim 1, wherein said left and right display surfaces each include a central surface, a temporal surface and a temporal edge, said central surface being spherical with radius R, spanning the full field of visual attention, and including said display center, and said temporal surface being a continuous cylindrical extension of said central surface toward said temporal edge of said display surface, having radius R, and spanning the full field of peripheral vision.
Claim 4
Dependent Claim
23 words
The apparatus for the viewing of stereoscopic images as claimed in claim 2, wherein said image display means is comprised of optic fibers.
Claim 5
Dependent Claim
32 words
The apparatus for the viewing of stereoscopic images as claimed in claim 3, wherein said left and right display surfaces are optic fiber ends coated with a single layer of glass micro-beads.
Claim 6
Dependent Claim
93 words
Apparatus for the viewing of stereoscopic images by a viewer, comprising: image display means including means for receiving signals representative of left and right images, left and right concave display surfaces, each surface having a display center, and means for displaying said left and right images on said display surfaces; mounting means for closely mounting said image display means at fixed positions relative to the viewer's head such that the viewer's centerlines of vision are aligned with said display centers; and nonobstructive optical means for focusing the viewer's eyes at said display surfaces.
Claim 7
Dependent Claim
93 words
Apparatus for the viewing of stereoscopic images by a viewer, comprising: image display means including means for receiving signals representative of left and right images, left and right concave display surfaces, each surface having a display center, and means for displaying said left and right images on said display surfaces; mounting means for closely mounting said image display means at fixed positions relative to the viewer's head such that the viewer's centerlines of vision are aligned with said display centers; and nonobstructive optical means for focusing the viewer's eyes at said display surfaces.
Claim 8
Dependent Claim
23 words
The apparatus for the viewing of stereoscopic images as claimed in claim 5, wherein said optical means is a pair of contact lenses.
Claim 9
Dependent Claim
85 words
The apparatus for the viewing of stereoscopic images as claimed in claim 6, wherein said left and right display surfaces each include a central surface, a temporal surface, and a temporal edge, said central surface being spherical with radius R, spanning the full field of visual attention, and including said display center, and said temporal surface being a continuous cylindrical extension of said central surface toward the temporal edge of said image display means, having radius R, and spanning the full field of peripheral vision.
Claim 10
Dependent Claim
23 words
The apparatus for the viewing of stereoscopic images as claimed in claim 7, wherein said image display means is comprised of optic fibers.
Claim 11
Dependent Claim
32 words
The apparatus for the viewing of stereoscopic images as claimed in claim 8, wherein said left and right display surfaces are optic fiber ends coated with a single layer of glass micro-beads.
Claim 12
Independent Claim
109 words
A method for the viewing of stereoscopic images by a viewer, the steps of said method comprising: receiving signals representative of left and right images; displaying said left and right images on left and right concave display surfaces, each of said surfaces having a display center; closely mounting said display surfaces at fixed positions relative to the viewer's head and adjacent the viewer's eyes such that the viewer's centerlines of vision are aligned with said left and right display centers; and viewing said images through nonobstructive optical means, said means altering the focal point of the viewer's eyes such that the viewer's eyes are focused at said display surfaces.
Claim 13
Independent Claim
109 words
A method for the viewing of stereoscopic images by a viewer, the steps of said method comprising: receiving signals representative of left and right images; displaying said left and right images on left and right concave display surfaces, each of said surfaces having a display center; closely mounting said display surfaces at fixed positions relative to the viewer's head and adjacent the viewer's eyes such that the viewer's centerlines of vision are aligned with said left and right display centers; and viewing said images through nonobstructive optical means, said means altering the focal point of the viewer's eyes such that the viewer's eyes are focused at said display surfaces.
Claim 14
Dependent Claim
141 words
The method as claimed in claim 10, further comprising determining the dimensions for said display surfaces and the position at which said display surfaces should be mounted relative to the viewer's eyes, said step comprising: measuring the interpupillary distance of the viewer; choosing a radius R less than or equal to one-half the interpupillary distance of the viewer; configuring each of said display surfaces with a central surface, a temporal surface, and a temporal edge, said central surface being spherical with said radius R, and spanning the full field of visual attention, and said temporal surface being a continuous cylindrical extension of said central surface extending toward said temporal edge and spanning the full field of peripheral vision; and positioning said display surfaces such that the distance between the viewer's eyes and said display surfaces is equal to said radius R.
