Color Blindness Diagnostic System Using Virtual Indication Objects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Color blind users often miss key visual cues in video games due to the lack of accessible color blind settings during interactive narratives, as these settings are typically unavailable or unadjustable during gameplay.
Innovation Solution
A system that utilizes virtual color blindness indication objects to automatically determine and enable color blind accessibility settings by prompting users to interact with objects distinguishable within specific visual spectra, allowing the game to adjust colors in real-time based on user interaction, thereby determining and adjusting dichromatic color blind accessibility settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If color blind accessibility settings are made available during gameplay, then color blind users can navigate and progress through narratives, but the device complexity and implementation difficulty increase
Solution Approach 1:
The system performs preliminary detection of color blindness type by presenting indication objects with specific color combinations during gameplay. The detection results are stored and used to automatically configure appropriate color blind accessibility settings, eliminating the need for manual configuration by users.
Solution Approach 2:
The system automatically detects the user's color blindness type and configures accessibility settings without requiring manual user input. The game monitors user interactions with color-coded objects and autonomously adjusts the visual presentation to accommodate the detected deficiency type.
2Adaptability or versatility
If color blind accessibility settings are adjusted in real-time during gameplay, then visual cues become accessible to color blind users, but the processing time and computational resources increase
Solution Approach 1:
The system performs color blindness detection and settings configuration in advance, during introductory sequences or paused states, rather than in real-time during active gameplay. This preliminary detection allows the system to prepare appropriate color transformations before the user needs them, minimizing impact on gameplay timing.
Solution Approach 2:
The system changes the color parameters of visual objects based on the detected deficiency type. By pre-calculating and storing transformation matrices for different color blindness types (protanopia, deuteranopia, tritanopia), the system can quickly apply appropriate color adjustments during gameplay without extensive real-time computation.
3Measurement precision
If multiple types of color blindness indication objects are instantiated, then accurate detection of specific deficiency types is achieved, but the quantity of virtual objects and system complexity increase
Solution Approach 1:
The system divides color blindness detection into separate categories for different deficiency types (protanopia, deuteranopia, tritanopia). Each category has specific indication objects with color combinations that are distinguishable to users with that particular deficiency type but not to others, allowing precise identification of the user's specific condition.
Solution Approach 2:
The indication objects serve multiple functions: they are both game elements that users interact with during gameplay and diagnostic tools for detecting color blindness type. The same objects used in game objectives also provide the color discrimination information needed to determine the user's visual deficiency type.

AI summary
Systems and methods for determining whether to enable color blind accessibility settings within the course of a user interactive narrative are described herein. Virtual color blindness indication objects containing colors that are visibly distinguishable within a single dichromatic visual spectrum can be utilized in objectives to determine a user's dichromatic visual deficiency type.
