A Study of an Evaluation Based on Physiological Responses of a Driver's Task and Stress Level While Maneuvering a Vehicle

To evaluate a driver's task and stress level objectively while maneuvering a vehicle, we paid attention for human's physiological responses under the condition. The eccrine sweat on a palm and a forehead, heart rate and a face temperature of a subject driver were monitored and measured continuously and quantitatively using the specified direct sweat measuring equipment, the electrocardiograph and the infrared thermometer respectively.

As a result of having analyzed these data physiologically, we propose that the driver's stress level can be objectively determined by the quantity of eccrine sweat, changes of heart rate and changes of face temperature.
