A new in-car yawn-detection system is being developed by an Indian-American and two other budding Indian scientists which will warn the sleeping driver inside a car and hence can prevent road accidents.
Aurobinda Mishra of Vanderbilt University, in Nashville and colleagues Mihir Mohanty of the Institute of Technical Education and Research (ITER), Orissa and Aurobinda Routray of IIT Kharagpur have developed a computer programme that can tell when you are yawning and could prevent road traffic accidents.
Around 100,000 road crashes occur due to driver fatigue every year, has been estimated by the US National Highway Traffic Safety Administration.
The programme that has been developed is based around an in-car camera hooked up to an image-processing software that captures a sequence of images of the driver's face.
It then analyses changes in the face and accurately identifies yawning as distinct from other facial movements such as smiling, talking, and singing.
