Holy Braille: Scientists developing Kindle-style tablet for the blind

[Conina]

"Refreshable Braille displays, as they are known, do exist, according to O’Modhrain, but the electronic versions can only display one line of text a time and are extremely expensive. A single line refreshable Braille display typically costs between $3,000 and $5,000, so a full page Braille display would cost somewhere in the region of $55,000, she added."

Or they just use the text-to-speech functions of a $100 - $400 tablet. ;)
