Color vision deficit correction

摘要

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.

主权项

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.
