It relies on the blind touching a series of elevated dots, which dictate what letter or number they “see.†While books written in this language have been around for quite some time, experts have been trying to create a refreshable Braille display, which would be similar to a computer screen.

That goal is now a little closer. According to experts at the NASA-operated Jet Propulsion Laboratory (JPL), in Pasadena, California, artificial muscles could be one possible answer to the problems associated with creating such a display. “I hope that sometime in the future we will have Braille on an iPhone. It will be portable and able to project a picture of a neighborhood popping up in front of!
you in the form of raised dots. A digital Braille operated by artificial muscles could provide for rapid information exchange, such as e-mail, text messaging and access to the web and other electronic databases or archives,†explains Yosi-Bar Cohen.
