In this study, five kinds of state variables characterizing the eye blinking behavior for detecting low arousal level of car drivers were investigated. This investigation was carried out in a driving simulator for clarifying what kind of state variables are useful for designing the algorithm of awaking alarm, in terms of minimizing the missing alarms in low arousal condition and the excess alarms in awaking condition simultaneously. In applying the ratio regarding closing/opening time of eyelid and the variation of this ratio for designing the algorithm, the time frequency of the missing alarms was approximately 1.5 % and extremely lower than the conditions when the algorithm was based on the other state variables like the total time for eye closing or the opening rate of eyelid. The excess alarms in applying this algorithm are also lower than the other algorithms. An effectiveness of awaking alarm based on this algorithm was also evaluated and clarified that the awaking effects by the acoustic alarm evaluated in terms of the fluctuation of RRI (ECG) was not sufficient, and the methodology for awaking the driver should be studied.
