Georgia Institute of Technology's new intraoral Tongue Drive system

The TDS iPhone/wheelchair interface
For those unfortunate enough to suffer from severe spinal cord injuries, the tongue is often the only extremity still under their control. To take advantage of this fact, engineers at the Georgia Institute of Technology have developed what they call the Tongue Drive System (TDS), a wireless, wearable device that allows the user to operate computers and control electric wheelchairs with movements of the tongue. The latest iteration, which resembles a sensor-studded dental retainer, is controlled by a tongue-mounted magnet and promises its users a welcome new level of autonomy with both communication and transportation.
