An Exploratory Study of the Causes of Discomfort From Using Braille Displays

Abstract

Low vision and blindness affect millions globally, with Braille displays serving as crucial input/output devices for individuals with these conditions. These displays act as a lifeline for Braille readers, providing access to literature, online resources, and supporting their occupational success. Despite the widespread use of Braille displays, this is the first study to assess their ergonomic impact on users. Surveying over 364 Braille display users in the US and beyond, we investigated the discomfort they experience and identified potential causes. Shockingly, 40% of participants reported experiencing discomfort when using their Braille displays. Although no specific manufacturer was consistently linked to discomfort, binary logistic regression revealed three demographic factors as significant predictors. The strongest predictor was Braille-reading expertise, with an odds ratio of 1.42, indicating that more proficient Braille readers were 1.42 times more likely to report discomfort. Age and Perkins keyboard experience were also significant, with odds ratios of 0.81 and 0.82, respectively, showing that younger and less experienced users were more likely to experience discomfort. These groundbreaking findings underscore the need for further research and immediate attention to improve the ergonomic design and usability of Braille displays to enhance the long-term comfort and success of their users.
