From the "That's freakin' cool" file 

USA Today -
A narrow strip of red plastic connects the Brain Port to the tongue where 144 microelectrodes transmit information through nerve fibers to the brain. Instead of holding and looking at compasses and bulky-hand-held sonar devices, the divers can processes the information through their tongues, said Dr. Anil Raj, the project's lead scientist. In testing, blind people found doorways, noticed people walking in front of them and caught balls. A version of the device, expected to be commercially marketed soon, has restored balance to those whose vestibular systems in the inner ear were destroyed by antibiotics.

Michael Zinszer, a veteran Navy diver and director of Florida State University's Underwater Crime Scene Investigation School, took part in testing using the tongue to transmit an electronic compass and an electronic depth sensor while in a swimming pool. He likened the feeling on his tongue to Pop Rocks candies. "You are feeling the outline of this image," he said. "I was in the pool, they were directing me to a very small object and I was able to locate everything very easily."

They plan to officially demonstrate the system to Navy and Marine Corps divers in May. If the military screeners like what they see, it could be put on a "rapid response" to quickly get in the hands of military users within the next three to six months. Work on the infrared-tongue vision for Army Rangers isn't as far along. But Raj said the potential usefulness of the night vision technology is tremendous. It would allow soldiers to work in the dark without cumbersome night-vision goggles and to "see out the back of their heads," he said.
