CASVI: Computer Algebra System Aimed at Visually Impaired People. Experiments

Abstract

The limitations in access to visually impaired people’s mathematical resources (VIPs) is undoubtedly one of the most significant obstacles for them to obtain, e.g., a degree in science. In this context, computational tools such as Computer Algebra Systems (CAS) are not blind-friendly, which causes solving elementary mathematical problems to become a challenging task for this group of people. This paper presents the Casvi system, a CAS for people with visual disabilities that allows carried out basics and advanced numerical calculations using the Maxima mathematical engine. Twenty-five VIPs tested the Casvi system to assess its functionality and usability. As a result, VIPs achieved a 92% accuracy when executing mathematical operations through Casvi. Finally, our system outperforms the LAMBDA system regarding the time needed by VIPs to perform mathematical operations correctly.
