- 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.

Konferensbidrag (refereegranskat)abstract
- We report the results of a pilot study that explores potential uses for BrailleTouch in the instruction of braille literacy for the visually impaired. BrailleTouch is an eyes-free text entry application for smart phones. We conducted individual semi-structured interviews and a focus group with four domain expert participants.

BrailleTouch : Designing a Mobile Eyes-free Soft Keyboard

Konferensbidrag (refereegranskat)abstract
- Texting is the essence of mobile communication and connectivity, as evidenced by today's teenagers, tomorrow's workforce. Fifty-four percent of American teens contact each other daily by texting, as compared to face-to-face (33%) and talking on the phone (30%) according to the Pew Research Center's Internet & American Life Project, 2010. Arguably, today's technologies support mobile text input poorly, primarily due to the size constraints of mobile devices. This is the case for everyone, but it is particularly relevant to the visually impaired. According to the World Health Organization, 284 million people are visually impaired worldwide. In order to connect these users to the global mobile community, we need to design effective and efficient methods for eyes-free text input on mobile devices. Furthermore, everyone would benefit from effective mobile texting for safety and speed. This design brief presents BrailleTouch, our working prototype solution for eyes-free mobile text input.

An Evaluation of BrailleTouch : Mobile Touchscreen Text Entry for the Visually Impaired

- We present the evaluation of BrailleTouch, an accessible keyboard for blind users on touchscreen smartphones. Based on the standard Perkins Brailler, BrailleTouch implements a six-key chorded braille soft keyboard. Eleven blind participants typed for 165 twenty-minute sessions on three mobile devices: 1) BrailleTouch on a smartphone; 2) a soft braille keyboard on a touchscreen tablet; and 3) a commercial braille keyboard with physical keys. Expert blind users averaged 23.2 words per minute (wpm) on the BrailleTouch smartphone. The fastest participant, a touchscreen novice, achieved 32.1 wpm during his first session. Overall, participants were able to transfer their existing braille typing skills to a touchscreen device within an hour of practice. We report the speed for braille text entry on three mobile devices, an in depth error analysis, and the lessons learned for the design and evaluation of accessible and eyes-free soft keyboards.

Braille Touch : Mobile Touchscreen Text Entry for the Visually Impaired

-
Konferensbidrag (refereegranskat)abstract
- We present a demonstration of BrailleTouch, an accessible keyboard for blind users on a touchscreen smartphone (see Figure 1). Based on the standard Perkins Brailler, BrailleTouch implements a six-key chorded braille soft keyboard [1]. We will briefly introduce audience members to the braille code, and then allow them to hold the BrailleTouch prototype and enter text, with the aid of a visual chart of the braille alphabet.
