Barrier-free VR teaching resource color optimization method for people with abnormal color vision

Abstract

The invention belongs to the field of teaching application of information technology, and provides a barrier-free VR teaching resource color optimization method for people with abnormal color vision, which comprises the following steps: (1) constructing a color cognitive factor system; (2) constructing a color evaluation model; and (3) generating a color scheme optimization model. According to the method, the requirements of people with abnormal color vision are comprehensively considered, various types of tasks are designed, and color cognition differences are analyzed; a color evaluation model is constructed by using an integrated learning method; the color scheme is optimized by firstly subdividing color pattern spots on an image and then screening the color pattern spots. According to the method, when non-professionals design and optimize VR teaching resources, the universality of a color scheme is achieved, and the fairness requirement of the educational resources is met.

Description

technical field [0001] The invention belongs to the teaching application field of information technology, and more particularly relates to a color optimization method for barrier-free VR teaching resources for people with abnormal color vision. Background technique [0002] The virtual teaching resources generated based on virtual reality (VR) technology have highly impactful visual effects, which can deepen learners' memory and understanding of knowledge content. However, people with abnormal color vision cannot perceive the color model of teaching resources like normal people, and it is difficult to effectively recognize the color scheme of virtual teaching resources. Since the design and development of virtual teaching resources are aimed at meeting the needs of people with normal color vision, they are not friendly to people with abnormal color vision in terms of color scheme and visual communication, causing them confusion and unfair results in the actual teaching proce...

AI Technical Summary

Problems solved by technology

[0003] At present, there are the following problems in the construction of color schemes for VR teaching resources: (1) As an emerging application field, the industry and researchers seldom consider the needs of people with abnormal color vision when designing and using resources; (2) As VR With the wide application of teaching resources, the demand for barrier-free VR teaching resources has increased sharply, and there is a lack of a general color evaluation model; (3) How to transform the existing color schemes and generate barrier-free VR teaching resources will save a lot of manpower, cost
