Portable, wireless drowsiness-detection system

This paper presents an EEG-based portable drowsiness-detection system for vehicle drivers. The system has a wireless recording unit without tether wires and employs a fast ICA-based detection algorithm to separate psychophysiological signals from motion artifacts of the driver. The system is implemented and tested on both benchtop and human subjects. The experimental results show that the proposed system can detect a driver´s drowsiness with minimal inconvenience to the driver.
