Relationship between biosignal, raction time, and eye blink depending on arousal level (I)

This paper describes the relationship among physiological, behavioral signal, and subjective evaluation depending on arousal level. Nz and reaction time hall similar pattern with KSS level, but eyeblink rate was different from these two parameters. Eyeblink rate increased slowly from KSS level 1 to 5, and had high increasing rate at KSS 7. But it showed steep descent at KSS level 9. From the result of reaction time test, since human performance was decreased rapidly above the KSS level 5, it is desirable to give a subject some stimulus such as sound or aroma to rise arousal level above the KSS level 3.
