"By routing signals from helmet-mounted cameras, sonar and other equipment through the tongue to the brain, researchers hope to give elite soldiers superhuman senses similar to owls, snakes and fish." - ABC News.
Researchers envision their work giving Army Rangers 360-degree unobstructed vision at night and allowing Navy SEALs to sense sonar in their heads. In testing, blind people found doorways, noticed people walking in front of them and caught balls. The device, known as "Brain Port", connects to the tongue using a narrow strip of red plastic where 144 microelectrodes transmit information through nerve fibers to the brain.
