Military researchers think the tongue could be key in their quest to create the super warrior of the future, giving soldiers sensory powers similar to owls, snakes and fish.Army Rangers with 360-degree unobstructed night vision, Navy SEALs sensing sonar in their heads while maintaining normal vision underwater -- scientists at the Florida Institute for Human and Machine Cognition are turning sci-fi into reality.By routing signals from helmet-mounted cameras, sonar and other equipment through the tongue to the brain, they hope to give elite soldiers superhuman senses.The question is that while animals' brains can process the extra stimuli, it is unknown whether human brains can adapt, said institute head Ken Ford. His facility specializes in "human-centered computing," fitting technology to people to make machines more user-friendly."Pit vipers, that's one reason they are so dangerous. They have heat detectors, infrared as well as natural vision," he said. "We know brains can do this."Dr. Anil Raj, the project's lead scientist, envisions Navy SEALs incorporating sonar into their senses, much like dolphins or whales.The research is designed to create superior troops, but Ford said the same technology could restore sight or hearing to soldiers wounded in war.
