AR Display Color Compensation for Color Vision Deficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Augmented reality systems fail to recognize and display information effectively for users with color recognition disorders, leading to a reduced user experience.
Innovation Solution
A method and system that query color vision sensitivity information to determine if a user has a color recognition disorder, and if so, provide a personalized color display mode to enhance recognition, involving a control device that generates compensation parameters for sub-pixels based on ambient brightness and visual field environment information to adjust image display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a standard color display mode is used in AR system, then the display is simple and consistent, but color recognition disorder patients cannot recognize the AR information
Solution Approach 1:
The system dynamically adjusts the color display mode based on the user's color vision sensitivity characteristics. The control device queries the data set to obtain color vision sensitivity information corresponding to the user's identity, then selects an appropriate color display mode (standard or personalized) to adapt to different user needs, making the display system flexible and adaptive rather than fixed
Solution Approach 2:
The system applies different color display modes to different users based on their individual color vision characteristics. By querying the data set with user identity information, the system identifies users with color recognition disorders and provides them with personalized color display modes that adjust color presentation locally for their specific needs, while normal users continue to receive standard display
2Ease of operation
If a personalized color display mode is provided for color recognition disorder patients, then the user experience is improved, but the system complexity increases
Solution Approach 1:
The system performs preliminary actions by pre-querying the user's color vision sensitivity information from the data set before displaying AR content. The control device obtains the user's identity information, queries the corresponding color vision sensitivity data in advance, and determines the appropriate display mode before the actual AR information is presented, ensuring seamless user experience without adding complexity during the display process
Solution Approach 2:
The system uses the user's identity information as a key to automatically query and retrieve their color vision sensitivity characteristics from the data set. This self-service mechanism allows the system to automatically identify users with color recognition disorders and apply appropriate display modes without requiring manual configuration or complex user input, simplifying the overall system operation
3Measurement precision
If color vision sensitivity information is queried from data set, then personalized display can be achieved, but additional processing time is required
Solution Approach 1:
The system performs the color vision sensitivity query operation in advance before the actual AR content is displayed. The control device obtains user identity information and queries the corresponding color vision sensitivity data from the data set beforehand, so that when AR content needs to be displayed, the appropriate color display mode is already determined and ready for immediate application, minimizing any time loss during actual use

AI summary
Disclosed is a control device querying a preset data set to obtain color vision sensitivity information corresponding to acquired identity information of a user of the augmented reality device; the control device judging whether the user is a color recognition disorder patient according to obtained color vision sensitivity information; the control device acquiring a personalized color display mode corresponding to the color vision sensitivity information as a target color display mode when the user is judged as a color recognition disorder patient; and the control device providing the augmented reality device with the target color display mode so that the augmented reality device employs the target color display mode to display an image.
