AI Technical Summary

Technical Problem

Traditional color testing methods cannot effectively screen for different degrees of color weakness, cannot assess color processing ability above the threshold level, are unfriendly to people with cognitive impairment, and have low testing efficiency.

Method used

A color vision testing method was used to assess color vision by presenting random color swatches on a test board. Subjects tracked the positions of the color swatches, and a color vision action model was constructed using Kalman filters and Gibbs sampling techniques to determine the color vision noise estimate and conduct a color vision assessment.

Benefits of technology

It enables the differentiation of color-blind individuals with varying degrees of color weakness, efficiently screens for color vision disorders, is suitable for individuals with cognitive impairments, features constantly changing stimuli, is more efficient than traditional methods, and quantitatively assesses color vision ability.

Abstract

The application provides a color vision test evaluation method and device and electronic equipment. The method is applied to a controller connected with a test palette. The test palette is used to present a stimulus color block with a specified size at a random position in each test. A subject can track and respond to the position of the stimulus color block. The stimulus color block is formed by two sub-color blocks intersecting and spacing. The two sub-color blocks include red-green sub-color blocks or yellow-blue sub-color blocks. The method comprises: obtaining reaction data of the subject when the subject is tested by the stimulus color block, and corresponding stimulus data. The stimulus data includes a plurality of test positions corresponding to different color contrast of the stimulus color block. The reaction data includes a plurality of reaction positions corresponding to the plurality of test positions under each color contrast. The color vision evaluation value of the subject is determined according to the reaction data and the stimulus data under each color contrast. The method can solve the problems in the traditional test method.
