Not too long ago I saw something on telly about a device that can help blind people see with their tongue...
What happens is that there is a camera which is attatched to the person's head and it picks up a low-res black and white image and transfers that to a small pad which is placed on the tounge. There are dots on the pad representing each pixel and each dot gives of a small pulse whose strength depends on the tone of its respective pixel.
When the camera is looking at an image the tongue can quite effectively pick up an image from the pulses which the brain can then interpret as a mental picture.
When I saw this it was only in the early stages, something like 8x8 pixels. But the guy tried it, looking at a white line, and he could clearly make out the line and could even tell which way it was slanted... when they develop it and fit a few more dots in this could be a brilliant way of helping the blind to see... its incredible.
