NON-INTRUSIVE ECG MEASUREMENT ON VEHICLE STEERING WHEEL AND DRIVER SEAT

摘要

Driver drowsiness is one of the major causes of deadly traffic accidents. Continuous monitoring of drivers' drowsiness thus is of great importance for preventing drowsiness-caused accidents. Previous psychophysiological studies have shown that heart rate variability (HRV) has established differences between waking and sleep stages [1, 2]. This offers a way to detect driver's drowsiness by analyzing HRV, which is typically measured and analyzed from electrocardiogram (ECG) signal.
