Tongue-controlled wheelchair could offer a faster way for quadriplegics to get around

Researchers are developing a method for quadriplegics to control wheelchairs and mouse cursors using only the movement of their tongue, and it’s turning out to be far more effective than one of the most popular current control schemes. Researchers from Georgia Tech have been working on a tongue-based control system since 2005, and in their latest trial runs, they’re finding that it’s a significantly more accurate way to issue commands than one existing and popular method.
