Driver Drowsiness Detection

Estimating reaction times (RTs) and drowsiness states from brain signals is a notable step in creating passive brain-computer interfaces (BCIs). Prior to the deep learning era, estimating RTs and drowsiness from electroencephalogram (EEG) signals was feasible only with moderate accuracy, which led to unreliability for neuro-engineering applications. However, recent developments in machine learning algorithms, notably stationarity-based approaches and deep convolutional neural networks (CNNs), have demonstrated promising results for a class of BCI systems, e.g., motor imagery BCIs, and affective state classification. These methods have not been systematically analyzed for EEG-based driver drowsiness detection and RT prediction.
