Clinical trial shows tongue-controlled wheelchair outperforms popular
  wheelchair navigation system
From: ECN - 12/02/2013

In a recent clinical study, individuals with paralysis were able to use a
tongue-controlled technology to access computers and execute commands for
their wheelchairs at speeds that were significantly faster than those
recorded in sip-and-puff wheelchairs, but with equal accuracy. This study is
the first to show that the wireless and wearable Tongue Drive System
outperforms sip-and-puff in controlling wheelchairs. Sip-and-puff is the most
popular assistive technology for controlling a wheelchair.

The Tongue Drive System is controlled by the position of the user's tongue. A
magnetic tongue stud lets them use their tongue as a joystick to drive the
wheelchair. Sensors in the tongue stud relay the tongue's position to a
headset, which then executes up to six commands based on the tongue position.

The Tongue Drive System holds promise for patients who have lost the use of
their arms and legs, a condition known as tetraplegia or quadriplegia.
