Tongue Drive lets the paralyzed travel via mouth movements

Tongue piercings have been around for a while now, but they've mostly been seen as about as useful and original as a kanji tattoo on your arm. But now researchers have actually come up with a device that would truly make such mouth metal useful.

The Tongue Drive System was created by developers at Georgia Tech and is a tool that would allow paralyzed individuals to operate a wheelchair with their mouth. The set-up involves a retainer with embedded sensors that operate in concert with a magnet attached to the tongue. The signals are then sent to an iPod or iPhone and translated into actual commands. The Tongue Drive System is still in its testing phase, but it could serve as a powerful alternative to the sip and puff device currently used by many paralyzed individuals.
