In 1829, a blind Frenchman discovered a technique that gave the visually impaired better access to literacy than any other extant method. Since then, Louis Braille’s system has been the standard learning tool for the blind. Yet Braille scripts printed on stacks of paper are odd in a digital age, when so much information is condensed into so little space. That’s because the alternatives — refreshable Braille displays and screen readers—are still inaccessible to many, especially in the world’s less developed corners. At a time of great leaps in technology, this is one problem worth solving.
