They have created an app called Braille Touch for the iphone. It allows people to type up to 63 characters by pressing different combinations of just six buttons. When using this app the user holds the phone away from the body and uses the three middle fingers of each hand to type different letters, numbers, and symbols. Spaces and backspaces are made by flicking the screen either right or left. Some blind people were able to type up to 32 words per minute with a 92% accuracy. The researchers are trying to get away from the QWERTY system which was designed in 1870. I think this app would be difficult to use at first, but i think it's a good idea to give visually impaired people a chance to text.
