The application enables visually impaired people type text using Braille code

Aim: The mobile application we created enables users to type text on a touch screen using Braille code. It serves a dual purpose: firstly, it is an accessible tool for sending sms messages and emails and secondly, it is a means for efficient and enjoyable Braille learning and practice. We anticipate that BrailleOne could help blind and visually-impaired people benefit from the long-term effects of Braille literacy.

Method: In BrailleOne, the screen is divided in three vertical sectors and is used as a one-hand keyboard. These three sectors represent Braille dots 1, 2 and 3 at first touch, and secondly, dots 4, 5 and 6. First column dots (i.e. 1, 2 and 3) are typed first and appear in blue. The remaining three dots (i.e. 4, 5 and 6) follow and appear in red. Apart from Braille typing, the following functions are also available: Swipe up=Copy to clipboard, Swipe down=Repeat, Swipe left=Delete, Swipe right=Space.

For example, to write “m” (Braille dots 1, 3 and 4), a user must first touch sectors 1 and 3 and then touch sector1 again. To listen to the message you have typed, touch the upper part of the screen.

The application "BrailleOne" won the 1st IMCL Student International Competition for Mobile Learning Apps, held on 19 -20 November 2015, in Thessaloniki, Greece
