The concept device pictured on the finger above is dubbed the Thimble. It features an embedded optical scanner that is capable of translating written text into Braille messages that scroll through the fingertip. The Thimble is also location aware and can connect to the Internet via a Bluetooth connection to your phone to deliver news or confirm your current location, all via Braille messages transmitted through the fingertip. Sounds like a fancy gadget that would be welcomed by folks with a visual disability.
