An automated braille writing tutor with multilingual exercises and educational games

Abstract

This work advances the state-of-the-art in assistive technology for the visually impaired by enhancing an automated tutor designed to teach beginner-level braille writing skills. The hardware component of the tutor is a low-cost device that provides an intelligent tactile interface that connects to a laptop or desktop computer. We demonstrate the many uses of this tutor including its multilingual capabilities, interactive exercises, and educational games. Preliminary field tests of the tutor in India, Zambia, and Qatar have demonstrated the usefulness of this automated tutor, and its potential to enhance braille literacy in developing regions.
