BrailleTouch is an eyes-free text entry application for mobile devices. Currently, there exist a number of hardware and software solutions for eyes-free text entry. Unfortunately, the hardware solutions are expensive and the software solutions do not offer adequate performance. BrailleTouch bridges this gap. We present our design rationale and our explorative evaluation of BrailleTouch with HCI experts and visually impaired users.
