The Usability of Mobile Devices for Individuals with Vision Impairments and Color Blindness, as well as Image Correctness

Abstract

About 0.5% of women and 8% of men suffer from color blindness, also known as Color blindness and Color vision deficiency (CVD), which affects the ability to distinguish between specific colors, such as red and green or blue and yellow. The purpose of this project is to investigate the efficiency, effectiveness, satisfaction and design of an adaptive mobile interface that enhances usability for people with Color Vision Deficiency disease. The developed program detects the user's color vision impairment using the Ishihara test and automatically modifies the interface to an appropriate color mode. 76 color-blind and an equal number of color-deficient users completed three different tasks in both adaptive and non-adaptive environments as part of a usability test. According to the findings, the adaptive interface considerably raised productivity by up to 20% and improved work effectiveness by up to 85%. Furthermore, there was a significant improvement in user happiness in the adaptive environment; Protanopia users reported a substantial 40.54% increase in satisfaction. This study shows that adaptive interfaces can significantly improve task performance and overall happiness for those with color vision deficits, underscoring their potential to improve the user experience.
