Prototyping a Multisensory Braille Interface for Visually Impaired and Blind Children

<p dir="ltr">Braille is a tactile reading system for visually impaired and blind (VIB) people, which involves distinguishing raised dots arranged in a 2x3 matrix, with a standardized dot height of ~0.5 mm, and a diameter of ~1.5 mm (UK Association for Accessible Formats, 2020). Braille literacy is associated with positive outcomes for VIB learners, but uptake is relatively low, partly due to a lack of engaging learning support. In this report, we present our initial work in the development of a multisensory digital Braille learning device for children, which we intend to further develop as a platform to support the development of Braille learning applications, including games and immersive, interactive experiences. In particular, we wish to explore the design space around accessible XR technologies for learning. Our initial work has incorporated feedback from visually impaired and blind (VIB) children, adolescents, and adults, as well as sighted Braille teachers. Currently, our focus is on the device's multisensory features, and playful affordances, designed to enhance Braille learning experiences and make Braille more accessible by engaging multiple senses for VIB individuals.</p>
