Operator Alertness System
OASYS provides a continuous real time measurement of eye position and eyelid closure. A direct measurement of drowsiness is calculated from the analysis of slow eyelid closures. In particular OASYS calculates the proportion of time the eyes are closed over a specified time interval and provides a visual gauge representing the driver’s drowsiness level and an audible warning when a preset drowsiness threshold is reached.
