Braille App Makes Tablets Accessible to Blind Persons
“The Braille system has allowed blind people to read the written word since 1825. Unfortunately, Braille doesn’t translate well to the glossy smooth surfaces of modern touch screen tablets and phones. A new app thinks it can change that…
The new app was created by NMSU undergraduate Adam Duran, Stanford Assistant Professor Adrian Lew, and Stanford Doctoral candidate Sohan Dharmaraja as part of the Army High-Performance Computing Research Center’s (AHPCRC) annual two-month summer immersion course. It allows the blind to use tablets via the Braille eight-button keyboard but with an important twist.
Instead of requiring the user to find virtual buttons on a glass surface (how frickin’ impossible is that?), the individual keys orient themselves to the correct finger whenever the user touches the screen. “They’re customizable,” Dharmaraja said in a press release. “They can accommodate users whose fingers are small or large, those who type with fingers close together or far apart, even to allow a user to type on a tablet hanging around the neck with hands opposed as if playing a clarinet.””
