A Touch-Free Smartphone the Disabled Can Control With Their Heads

Shortly after appearing on Israeli television with a new computer game you control merely by moving your head, Oded Ben Dov got a phone call. It came from a complete stranger who just happened to see this TV appearance, and he had a question. "I wasn't sure if it was a prank call or not, but then he started to say some serious stuff," Ben Dov remembers. The man on the other end of the line was Giora Livne, a former Israeli navy commander and electrical power engineer. He'd been quadriplegic for seven years, he explained, which made it impossible to use a smartphone without help.
