Suffering from "locked-in syndrome", Jeff Hall communicates with the world using just one finger.
At 40 years old he was paralyzed by a stroke and left with very little limited movement in his head and limbs.
But with the help of technology he can live independently and has recovered some of the freedom he lost.
He can speak using text to voice technology, an apple computer and an android phone.
But he worries that as technology develops it could alienate disabled people like him.
Multi-gesture controls - such as two-finger scrolling on the iphone - for example, are impossible for people in his position.
He also questions whether open source software could pose a bulwark to accessibility if adhoc developments don't remember disabled users as they drive to move forward.
