Brain-Computer Interfaces Are Already Here - Robot Watch

For the first 54 years of his life, Dennis DeGray was an active guy. In 2007 he was living in Pacific Grove, Calif., not far from the ocean and working at a beachside restaurant. Then, while taking out the trash one rainy night, he slipped, fell, and hit his chin on the pavement, snapping his neck between the second and third vertebrae. DeGray was instantly rendered, as he puts it, "completely nonfunctional from the collarbone south." He's since depended on caregivers to feed, clothe, and clean him and meet most any other need.
