The Tongue Drive System

The Tongue Drive system was made at Georgia Tech. It allows people who are unable to use their hands to use a computer or a wheelchair. The user has to get their tongue pierced than it will be able to track what your tongue does through magnetic sensors in a retainer so it can replace the computer mouse or a joystick on a wheelchair. It used to have head mounted magnetic sensors but the headgear was uncomfortable and had to be recalibrated whenever it slipped.
