Tactile Access to Visualized Statistical Data Using R
JooYoung Seo (The Pennsylvania State University)
Statistical analysis has been considered a challenge for blind people not solely because of its complexity, but also due to the lack of statistical software compatible with assistive technology. As one of the BrailleR package contributors and a screen reader user myself, I, along with my sighted colleague, have developed a function that optimizes visual graphs into ready-to-print braille graphs so that blind R users can print them out and produce tactile facsimiles using a Swell-Form Graphics Machine. This function has been implemented with the name of BRLThis() to Dr. Godfreyâ€™s Github version of BrailleR, and has been improved with ongoing experiments. This function is expected to help blind data analysts who want to get the big picture of their data. By allowing users to interpret the tendencies directly in a tactile form, it could serve to compensate for the limitations that text-based descriptions possess.
