A Hybrid Vigilance Monitoring Study for Mental Fatigue and Its Neural Activities

Mental fatigue causes many casualties and economic losses from unexpected accidents. Electroencephalograph (EEG) signals are most commonly used for vigilance estimation. In this paper, we report a novel hybrid vigilance monitoring and warning system based on EEG and eye movement signals to detect mental drowsiness. This system collects eye movement information to quickly detect unsafe driving behavior and also gives real-time warning of driving fatigue by monitoring EEG activity. It also uses Fisher score electrode analysis to locate the cortical regions involved in vigilance and reduces the number of channels required. Fewer channels make the integration of vigilance monitoring technologies easier to implement and use as a vehicle safety aid. The self-adaptive system can provide various online monitoring and warning strategies for adapting to different individual physiological situations and complex external environments. For new users, the non-model module can be used for online monitoring without prior training and analysis.
