BrailleTouch uses the three dots on each side of the screen to represent Braille alphabet. BrailleTouch is designed to be used with the touch screen facing away from the user. The 1st, 2nd and 3rd fingers of both hands are used to touch the six dots. Researchers claim that BrailleTouch allows users to type eyes-free with 92 percent accuracy and 32 words per minutes.
