Evaluating body movements of a drowsy driver with pressure distribution sensors

The purpose of this research is to develop a method to detect driver drowsiness with pressure distribution sensors on the driver seat. Use of such sensors has an advantage that the measurement can be done in a non-intrusive manner, and that sensing data can always be obtained while driving. We conducted an experiment with a fixed-base driving simulator. The results suggested that driver body movement increases when driver drowsiness begins to increase.
