Ordinary mobile phones can also be used by the blind, but they are unable to see texts such as messages. However, this Braille phone allows them to read and write text files. The difference between this Braille phone and a regular one is that there are thousands of tiny pegs on the phone's keyboard. These pegs can rise or fall according to different codes. Moreover, these pegs can be converted into Braille for helping the blind to read and write text files. Currently, this Braille phone is only a concept, and it remains unknown when it will become a tangible product.
