Sighted people, myself included, do it every day and take it for granted. Unfortunately, because of physical challenges, not everyone has the privilege to drive. My team of researchers wants to find a way to give the blind the ability to drive.

When we first announced that we were going to take up this challenge, many thought we were crazy, and most of the critics doubted that it could be done. Even some of my colleagues challenged us on the idea of developing a vehicle for the blind.

The car we're developing for the blind uses a sensor to measure acceleration, cameras to detect the lanes of the road, and laser range finders. Drivers are fitted with special gloves with vibrating elements that can be used to control steering and a massage chair that conveys information about the vehicle's speed and about how best to use the gas and brake pedal.

I've gotten hundreds of letters, e-mails, and phone calls from people around the world; many times these are to thank and congratulate us, but sometimes we get letters of strong concern and criticism.
