Abstract
A method for deriving a fatigue score (100) indicative of a current drowsiness state of an operator (1) measures a plurality of signals (10, 20, 30, 40, 50, 60, 70, 80, 90) and derives a personalized fatigue score (100) for the operator using these signals (10, 20, 30, 40, 50, 60, 70, 80, 90) in a weighted and operator-personalized way.
