Tablet-based Braille entry via a framework promoting custom finger spacing

Abstract

This paper outlines the development of the AccessBraille framework, an iOS framework designed to provide a Braille keyboard to an iOS application. The proof-of-concept app developed with this framework is presented as an example of how the framework can be utilized, demonstrating its use across multiple contexts where Braille entry is used. The AccessBraille keyboard framework provides a natural way for blind users to enter US Type 1 or Type 2 Braille text into an app. The keyboard allows for users to customize finger placement for comfort and hand size. User feedback was solicited through observation on the task of entering Braille using the framework at various stages of development. In addition, feedback was gathered for the deployed app itself. The feedback will provide input into the prioritization of revisions and new features. © 2014 Springer International Publishing.
