Blink of an eye: An autonomous device can track the movements of a person's eye using an infrared light

摘要

SWEDISH ENGINEERS have developed a device claimed to be a first for embedded eye-tracking technology on a single chip. Stockholm-based Tobii Technology claims that the device can be employed for a variety of applications, including detecting drivers who are becoming drowsy at the wheel. Other uses include medical diagnostics and gaming. The device is installed on the steering wheel or dashboard and uses an image sensor to detect multiple times per second if a driver's eyes are alert.
