“…In general, these solutions can be grouped into three categories according to the fatigue detection methods, which are based on monitoring (1) vehicle driving parameters, (2) driver physiological parameters, or (3) driver facial features [ 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 ]. The first category includes sensors for monitoring steering wheel touch, the steering wheel angle, the travel path and the vehicle’s speed [ 12 , 13 , 14 ]. Failure to detect a hand on the steering wheel or the detection of steering wheel turns beyond the lane may indicate unusual driver behaviour due to fatigue.…”
