The entire women's team at MIT created a cheap, hand-held device that provides printed text for real-time translation of Braille, which will greatly increase written material for the use of accessible blind people.

Here's how it works: The device has an internal camera that prints text and then uses optical character recognition software to convert the photos into digital text. Then, the translation of the text into Braille, and the mechanical system proposes and forms a character that is read on the fingertips of a person, on the surface of the touch. 
Although the number of characters in the current version, which can be converted and displayed is limited, the development team wants to be able to scan the entire page at one time and display two lines of text at a time.
In the world of audiobooks and text-to-audio technologies, is Braille still important? Although the sound system is easier to use, a written system like Braille does not instill the same understanding of the language. Studies have shown that reading and writing braille significantly increases job opportunities. But now, less than 10% of American blind people can read it.
Part of the problem is that creating Braille text is expensive, which greatly limits the choice of visually impaired people.
