OneHandBraille: An alternative virtual keyboard for blind people

Abstract

This paper presents a new text entry method for visually impaired people called OneHandBraille. This gesture-based method uses only one user’s hand typing the Braille Code. Blind users do not have to learn a new code, some dots are simply replaced by swipes on the surface of a touch screen. The article describes the method, the evaluation of prototype implementation for mobile devices, and comparison to the most similar existing solution. The obtained results are encouraging and bring hope that the method can be useful in the real mobile application.
