Using your voice to pilot your computer

Roland Piquepaille's Technology Trends has a post on how a team of scientists of the University of Washington (UW) has developed Vocal Joystick, a software which enables people with disabilities to control their computers using the sound of their voice and without the need to use a mouse:
Their virtual computer mouse driven by sound has already been tested at the UW Medical Center with spinal-cord-injury patients and other participants with varying levels of disabilities. The researchers, who developed their own voice-recognition technology, hope to have a prototype available online this fall. But read more...
