From TED2011: Dennis Hong: Making a car for blind drivers

From the international TED2011 event: Using robotics, laser rangefinders, GPS and smart feedback tools, Dennis Hong is building a car for drivers who are blind. It's not a "self-driving" car, he's careful to note, but a car in which a non-sighted driver can determine speed, proximity and route -- and drive independently.

Hong, an associate professor of mechanical engineering and director of the Robotics and Mechanisms Laboratory at Virginia Tech spoke about the Blind Driver Challenge project and its Daytona Rolex24 debut at the TED2011 event, held in early March in Long Beach, Calif. Among his fellow speakers: Bill Gates, Bill Ford and Roger Ebert. Watch the video.
