See-thru Display Device for Color Vision Deficit Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Individuals with color vision deficiency face difficulties in distinguishing certain colors, which can lead to disabilities in everyday life and is currently unaddressed by medical treatments.
Innovation Solution
A see-thru display device that uses augmented reality to superpose virtual imagery onto real imagery, accentuating colors poorly distinguishable by the user, thereby improving color-resolving ability by configuring the virtual imagery to shift or enhance colors in real-time within the user's field of view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If virtual imagery is superposed onto real imagery to enhance color distinction, then color-resolving ability is improved, but device complexity increases
Solution Approach 1:
The patent introduces a see-thru display device as an intermediary between the user and the real world. This device superposes virtual imagery onto real imagery to enhance color distinction for users with color vision deficiency. The display device acts as a mediator that processes visual information and presents enhanced color perception without requiring direct modification of the user's visual system, thereby improving color-resolving ability while maintaining manageable device complexity through a dedicated intermediary system.
2Loss of information
If virtual imagery is used to accentuate colors, then perception of the visual world is improved, but loss of information occurs due to superposition of virtual and real imagery
Solution Approach 1:
The patent applies local quality by selectively enhancing specific color regions in the visual field rather than uniformly processing all visual information. The system identifies areas where color distinction is needed and applies virtual imagery enhancement locally to those regions. This targeted approach improves color-resolving ability for specific loci while minimizing information loss by not altering the entire visual field, thereby balancing enhancement needs with information preservation.

AI summary
Embodiments related to improving a color-resolving ability of a user (12) of a see-thru display device (16) are disclosed. For example, one disclosed embodiment (52) includes, on a see-thru display device, constructing (62) and displaying (66) 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.
