Solution Overview

Problem

Current methods for designing color accessible content, such as color vision simulators, are limited in their ability to provide real-time feedback on color accessibility for individuals with vision impairments, often requiring manual corrections after content creation and lacking user-friendly interfaces, which increases labor costs and reduces the effectiveness of color accessibility in digital spaces.

Innovation Solution

The use of confusion lines in a graphical user interface to visually indicate curves of confusion for colors, allowing for real-time identification of color conflicts and automatic optimization of color sets for accessibility, leveraging an objective function that includes CVD alignment, out-of-gamut, distinguishability, and faithfulness terms to ensure colors are perceivable by individuals with color vision deficiencies.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If color vision simulators are used to check color accessibility, then color accessibility can be evaluated, but real-time feedback is not provided and manual corrections are required after content creation

Engineering Contradiction:
Improvecolor accessibility evaluationVSAvoidtime for manual corrections
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent applies preliminary action by providing real-time feedback during the color selection process itself, rather than performing accessibility checks after content creation. The confusion line visualization is displayed immediately as users select colors, allowing them to prevent inaccessible color combinations before finalizing the design, thereby eliminating the need for time-consuming manual corrections later.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements continuous feedback through the graphical display of confusion lines that update in real-time as users interact with the color picker. This feedback mechanism visually indicates which color combinations may be inaccessible to individuals with color vision deficiencies, enabling users to adjust their selections immediately and ensuring color accessibility without requiring post-creation revisions.

Inventive Principle:
Principle #23Feedback

2Adaptability or versatility

If traditional color selection methods are used, then design flexibility is maintained, but color accessibility for individuals with vision impairments cannot be ensured

Engineering Contradiction:
Improvedesign flexibilityVSAvoidcolor accessibility
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent introduces confusion lines as an intermediary visual element between the color selection interface and the user. These confusion lines act as a mediator that translates complex color vision deficiency simulations into simple visual indicators, allowing users to maintain full design flexibility while automatically ensuring color accessibility. The intermediary layer reconciles the conflict between creative freedom and accessibility requirements.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Measurement precision

If manual color accessibility checking is performed, then color conflicts can be identified, but labor costs increase and productivity decreases

Engineering Contradiction:
Improvecolor conflict identificationVSAvoidcontent creation efficiency
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The patent implements self-service by enabling the color accessibility checking function to be automatically performed by the system itself through real-time confusion line visualization. Instead of requiring users to manually check color combinations or seek external accessibility tools, the interface autonomously provides accessibility feedback during the normal color selection workflow, thereby maintaining high productivity while ensuring accurate color conflict identification.

Inventive Principle:
Principle #25Self-service

4Reliability

If color themes are optimized for accessibility, then color distinguishability for individuals with CVD improves, but the original design intent may be altered

Engineering Contradiction:
Improvecolor distinguishabilityVSAvoidoriginal design intent
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The patent applies partial action by providing users with information (confusion line visualization) rather than automatically making design decisions for them. The system shows which color combinations may be problematic but allows users to selectively adjust only those specific color pairs that cause accessibility issues, preserving the overall design intent while improving color distinguishability where necessary. This approach avoids excessive action that would fundamentally alter the entire color scheme.

Inventive Principle:
Principle #16Partial or excessive action

AI summary

Embodiments of the present disclosure relate to computer storage, methods, and systems for the optimization of accessible color themes. Systems and methods are disclosed that leverage the use of confusion lines to identify and highlight relationships between colors that may be inaccessible (e.g., indistinguishable) for a person with a vision impairment, such as a color vision deficiency. In some embodiments, a graphical user interface is provided that, based on a selection of colors in a color wheel, visually indicates curves of confusion for each color in the selection of colors. Each curve of confusion visually indicates a confusion of colors for a type of vision impairment, such as a CVD.
