I recently wrote about Erik Weihenmayer who is the adventurer who is blind. Here is a video of him demonstrating and using the Brainport Vision Device which converts visual data from a camera in to tactile data that he receives via a panel on his tongue.
This technology got quite a bit of exposure a few months ago, but I hadn't seen any good demonstrations of this before now. So, enjoy.
