Researchers at the University of Washington have developed software which allows the user to use vocal sounds to control their computer. The Vocal Joystick differs from previous methods in that the user does not have to use actual words to complete tasks. The controls are based off of simpler, more easily identifiable sounds such as vowel or consonant sounds. This results in much smoother operation and less error produced by the software. This could be a major breakthrough for easier computer access for people with impaired motor function.
