In the future, you may not need to type to get online. You'd use your tongue.
Researchers at Georgia Tech are working on a tongue-powered computer control pad to help disabled users. The Tongue Drive System turns the tongue into a sort of joystick that allows the disabled to manipulate wheelchairs, use home appliances and control computers. The system uses a magnet under the tip of the tongue, and its movement is tracked by sensors on the sides of the cheeks.
The system still needs work, though. It uses bulky headgear, the magnet is too big and the software needs tinkering. Still, the tongue system is promising enough that Georgia Tech has gotten grants from the National Science Foundation and the Christopher and Dana Reeve Foundation.
