Abstract
Tailored text input methods for visually impaired and blind users are
needed on touchscreen devices to support their accessibility. Therefore, we developed a new Braille-based text input method named EdgeBraille, which allows entering Braille characters by swiping one finger along the edges of the touchscreen. The approach was compared with the current standard method of a talking keyboard, first in a short-term lab study (14 participants) and then during two weeks of daily training (7 participants). Overall EdgeBraille was perceived
well by the users. In terms of user performance we found no significant differences between the two methods. Based on the evaluation results and the feedback of our participants, we discuss advantages and disadvantages of Braille-based methods in general and EdgeBraille in particular, as well as possibilities for improvements.
