Submission + - Stephen Hawking's new speech system is free and open-source (wired.co.uk) 1
"Over three million people around the world are affected by motor neurone disease and quadriplegia and because the system created for Hawking is based on open-source software, it could potentially be adapted to suit many of them. Different functions can be enabled by touch, eye blinks, eyebrow movements or other user inputs for communication. Hawking and Intel hope that because the system is open and free it will be adopted by researchers who will want to use it to develop new solutions for those with disabilities."
