Many will believe that driving is an activity solely reserved for those who can see. Driving of blind person independently was thought to be an impossible task .Until now; Dennis Hong made a car that a blind person can drive freely and independently.
Dr.Hong worked on a project DARPA Urban Challenge where they secured third position by building a car that can drive itself. It was a simply a robotic car. But the problem with this car was that it was just like an elevator. You just press the button and it takes you to your destination.
So, their idea of putting a blind man into the Robot car was cancelled, as they wanted to build a car that a blind person can drive independently.
So, they invited dozens of blind youth to drive their prototype car. The prototype car was just the start; it was made for controlled environment. But, in real life the road is much complex place than a racetrack. One has to measure the oncoming vehicle, and the vehicle behind them. They have to look for the pedestrians and for any kind of sudden decision. For people with eyes it doesn’t seem to be heard task, but for a blind person it seems rather impossible.
So, they built it.

For that they built lots of non-visual user interfaces to communicate with visually impaired driver. They built a 3D sound system, vibrating vests, leg stripe etc.
