A small team of engineers from Stanford and New Mexico State University released a free app which makes typing Braille easy on tablet computers.
Blind people would find the uniform key tablet to be inappropriate as the traditional Braille typewriters have physical keys assigned to each finger. The iBrailler app automatically moves the keys to be just where the fingers are.
The app registers the location of all the fingers when the user simply places all the fingers on the screen before typing. Lifting the hands off the screen and placing them back recalibrate the keys.
