DeafBlind can see with their tongue???

That's right. That is what I said!

It is possible to see with your tongue! Bizarre huh?

I'll admit that when I first read this, I was extremely suspicious. I thought it had to be a hoax or something. But then as I continue reading, it started making sense. I even went online to verify the data. Shockingly enough, it is true.

--------------------------

Here's the story in laymen terms.

The world is pretty much divided into insulators (rubber, plastics, etc) and conductors (metals, water, muscles, etc).

We are made of mostly water. Our muscles, fat, and bones are made of mostly water as well. Therefore, that means we are a very good conductor.

With that being said, your tongue is actually a muscle. Well, many muscles to be accurate. These muscles help you to swallow, chew, talk, etc. Your tongue is hooked up to the brain with many different nerves. (refer to Figure 1).

Every time you take a bite, the taste buds on your tongue will send out an electrical signal through the nerves to your brain and your brain will tell you if it's delicious or bad tasting.
--------------------------------
So our brilliant scientists thought, "Why can't we do that with a device that will control the current flow of electricity and put it on the top of their tongue?"

Well, that's what they have done. It is called BrainPort.

You literally put the sunglasses on, put the white device on the top of your tongue, and turn it on with the remote control. Boom! Like magic, you can see!

This is currently a protoype and not for sale anywhere in the world. However, if you would like to particpate in this project, you may contact Dr. Amy Nau @ University of Pittsburgh, Dr. William Seiple of Lighthouse International in New York, or Dr. Aimee Arnoldussen @ Wicab, Inc in Wisconsin.

Now here's the million dollar question.

Is it really "seeing" ????
