I saw this and thought it was brilliant – had to share it so you too can be in awe of a wonderful piece of functional design.
As it has been described elsewhere:
The Haptic Braille is a mouse-like device that’s capable of translating ordinary text into braille on its surface. This means that blind and partially sighted people can read virtually anything the sighted can. The technology uses optical character recognition. Simply skim it over any text and wait for the haptic feedback. I like how you can pocket and carry it over to the library. Just imagine how many books literally become available at your fingertips. Splendid!
