Braille tablet

​Austrian company, Blitab, is developing a useful device for blind people – it "displays" a full page of Braille on a tablet. The device uses small haptic "bubbles" on the surface that raise or lower for each character. Previous Braille readers that have been around for many years only display one line of text and are somewhat clunky to use.

The Blitab directly converts text on USB sticks, memory cards, web browsers and NFC. The device also has a built in Braille keyboard. They're apparently available for pre-order (http://blitab.com/pre-order) but no word on availability or shipping dates.

This should go a long way to improve the lives of the  40 million blind people in the world, providing access to the web and other services currently only available via verbal reading apps.
