Tablet app brings new touch to Braille
Can a tablet designed for those who can see become accessible to those who can't? A research group at Stanford has created a Braille writer that has the potential to revolutionize a stagnant market.
Software developed during a summer course at Stanford University could one day radically shift the way the visually impaired use modern tablets, potentially removing the need for a wireless Braille display.
Adam Duran, a senior at New Mexico State University, has developed a stunning way for blind people to type on tablets. Duran created the touch-screen Braille writer software with Adrian Lew, a Stanford assistant professor of mechanical engineering, and Sohan Dharmaraja, a doctoral candidate.
It's all in the fingertips. The eight keys (similar to a standard Braille keyboard) in the software do not have a predefined position, but rather work with the location of the fingers. A user simply presses eight fingers anywhere on the screen, and voila, the keys are automatically oriented to that location.
If there's a problem, users simply lift their fingers and put them down again. As shown in the video below, typing is a breeze. Curiously missing is the mention of haptic feedback (vibration), or voice support, but for a first version this software is very encouraging.
