The Attention Control System (ACS) consists of a camera installed in the cockpit to monitor the driverÂ’s blinking movements. The development of this system is aimed at eliminating the risk of driver inattentiveness, by constantly keeping track of the frequency and duration of eyelid movement. If the computer connected to the camera perceives the driver to be at risk of sleepiness at the wheel, the system can warn him ahead of time. Similar technologies are currently being developed by Lexus, Mercedes-Benz and Volvo.
