Bangalore: Scientists claim that they have developed an eye tracking device that will keep drowsy drivers alert. A device that has built in sensors and will alert the driver with an alarm at the moment when the driver's eyelids have closed, has been invented by a team at the Fraunhofer Institute for Digital Media Technology in Ilmenau, Germany.
The device has been named as 'eyetracker' and it costs one-tenth the price of similar devices. Eyetracker can be installed in any model of the car. "With conventional systems, every person whose line of vision is to be monitored has to complete more or less time-consuming preparations. Because every head, every face, every pair of eyes is different," said Peter Husar, Fraunhofer developer. "What we have developed is a small modular system with its own hardware and programmes on board, so that the line of vision is computed directly within the camera itself," Husar added.
The system can easily identify the spatial position of the pupil and the line of vision since the eyetracker is fitted with at least two cameras that record images stereoscopically. Eyetracker is only roughly half the size of a matchbox and practically undetected when mounted behind the sun visor and in the dashboard. The tiny lenses are just three to four millimeters in diameter.
Marketing and advertising researchers can use it as a useful tool in determining which parts of the poster or advertising spot receive longer attention from their viewers.
