[Examination of blinking-rate in a simulated four hour driving task].

In a driving simulation task performance and physiological measurement of strain was registered on 3 subjects in 9 experiments. The time-variant behaviour of blinking-rate was examined together with performance, self-rating and physiological strain. The correlating results make blinking-rate a possible indicator for activation of willingness to good performance. A multidimensional concept for assessment of the degree of individual fatigue is presented and validated in respect of working-time.
