SingleTapBraille: Developing a Text Entry Method Based on Braille Patterns Using a Single Tap

Mrim Alnfiai, Srinivas Sampalli
2016 Procedia Computer Science  
Visually impaired people tend to use touchscreen devices because these devices support a screen reader function, providing a cheaper, smaller alternative to screen reader machines.  ...  This paper presents our initial keyboard design and our explorative evaluation of SingleTapBraille conducted with braille instructors and visually impaired users.  ...  The main concept behinds our new input method is the clustering of activated braille dots for each character.  ...
