Driver drowsiness detection is a car safety technology which helps prevent accidents caused by the driver getting drowsy. Various studies have suggested that around 20% of all road accidents are fatigue-related, up to 50% on certain roads.
Why is driving drowsy detected?
The driver drowsiness detection is based on an algorithm, which begins recording the driver’s steering behavior the moment the trip begins. It then recognizes changes over the course of long trips, and thus also the driver’s level of fatigue.
How do you detect drowsiness?
Many researchers have considered the following physiological signals to detect drowsiness: electrocardiogram (ECG), electromyogram (EMG), electroencephalogram (EEG) and electro-oculogram (EoG) (Table 3). Some researchers have used the EoG signal to identify driver drowsiness through eye movements [12,28,61].
How does EEG detect drowsiness?
Drowsiness level can be readily detected through measurement of human brain activity. The electroencephalogram (EEG), a device whose application relies on adhering electrodes to the scalp, is the primary method used to monitor brain activity.
