Affordable 14-line Braille Display Tablet

The folks at Blitab have created a tablet with a touch screen to search and select with, but it is not the main display. Instead it translates text from the Web and other digital sources into Braille at about 65 words per display (depending on what you are reading). There have been Braille display devices for a while, but they have been limited to a single line which can only hold about 5 words on average by moving rigid pins up and down to form each letter. They also cost thousands of dollars. The Blitab Braille display uses layers of fluids and a special proprietary membrane they aren’t talking about to form an entire screen’s worth of words, and when they finish refining it they plan to put it on sale in the fall for around $500. Using it 8 hours a day to read will give you a battery life of 5 days, a discharge rate I wish my own tablet could match. This has the potential to open up a lot of the online world and its resources to the visually impaired at an affordable price in a way that has never been available to them before. There is a similar project in development at the University of Michigan, but so far it is mostly in the research stage. Thanks to the MIT Technology Review for the heads up on this one.
