The second, third, fourth conditions is to drive automobile under three different concentrate level of call). We measured heart rate as a physiological index and NASA-TLX, performance as a subject index. The result shows, using hands-free supporter when driving showed lower performance of 18% and shorter heart rate interval and higher psychological work load of about 3.5 times under fourth condition. The reaction capacity of body appeared low attentiveness depends on telephone conversation when driving.
