Color vision deficit correction
First Claim
Patent Images
1. In a see-thru display device, a method to address a color vision deficiency, the method comprising:
- constructing virtual imagery to superpose onto a real world background viewable through the see-thru display device, where constructing the visual imagery includes identifying one or more loci of one or more real world objects of a color poorly distinguishable based upon the color deficiency and identifying a focal point of a user of the see-thru display device, the virtual imagery configured to accentuate the one or more loci such that loci nearer to the focal point are accentuated to a greater degree than loci farther from the focal point; and
displaying the virtual imagery such that the virtual imagery is superposed onto the one or more real world objects, in spatial registry with the one or more real world objects, in a field of view of the see-thru display device.

Abstract
Embodiments related to improving a color-resolving ability of a user of a see-thru display device are disclosed. For example, one disclosed embodiment includes, on a see-thru display device, constructing and displaying virtual imagery to superpose onto real imagery sighted by the user through the see-thru display device. The virtual imagery is configured to accentuate a locus of the real imagery of a color poorly distinguishable by the user. Such virtual imagery is then displayed by superposing it onto the real imagery, in registry with the real imagery, in a field of view of the user.

10. A see-thru display device configured to address a color-resolving ability of a user having a color vision deficiency, the see-thru display device comprising:
-
a front-facing camera configured to acquire an image of a real world background viewable through the see-thru display device; a logic subsystem operatively coupled to a storage subsystem, the storage subsystem storing instructions that cause the logic subsystem to construct virtual imagery to superpose onto the real world background, the virtual imagery configured to accentuate one or more loci of one or more real world objects of a color poorly distinguishable based upon the color vision deficiency wherein constructing the virtual imagery includes identifying a plurality of loci of matching colors in the real world object and overwriting the loci with one or more of text, a symbol, and a segmentation pattern to indicate the matching colors; an eye tracker configured to track a focal point of the user, wherein the virtual imagery is configured to accentuate a first locus nearer to the focal point to a greater degree, and accentuate a second locus farther from the focal point to a lesser degree; and a microdisplay configured to display the virtual imagery such that the virtual imagery is superposed onto the one or more real world objects, in registry with the one or more real world objects, in a field of view of the see-thru display device. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. In a see-thru display device, a method to improve a color-resolving ability of a user of the see-thru display device based upon a color vision deficiency of the user, the method comprising:
-
acquiring, with a front-facing camera of the see-thru display device, an image of a real world background viewable by the user through the see-thru display device; recognizing a first real world object and a second real world object in the acquired image; constructing virtual imagery to superpose onto the first and second real world objects, the virtual imagery configured to accentuate loci of the first and second real world objects having a color poorly distinguishable based upon the color vision deficiency, and constructed to accentuate loci of the first real world object to a greater extent than loci of the second real world object based on a nature of the first real world object; and displaying the virtual imagery such that the virtual imagery is superposed onto the first and second real world objects, in spatial registry with the first and second real world objects, in a field of view of the see-thru display device. - View Dependent Claims (19, 20)
