Click the Giz link below and watch the videos. Up. Up. Left. Faster. Very fast. Slower. Up. Mouse-click. This is how one controls the Vocal Joystick, a device developed at the University of Washington. Its purpose is to help disabled and paralyzed people use computers in a much more efficient way.
The way it works is that a microphone in the joystick samples your voice 100 times a second and then pumps it through software to recognize movements. You say “Up.”, the cursor moves up. Very simple. Put a techno beat to it and you may have the Winter 2007 club hit of the season.
