| Outline of Final Research Achievements |
It was found that drowsiness, which has been evaluated by the Japanese version of Karolinska sleepiness scale, could be estimated in two stages ("presence of strong drowsiness" or "absence of strong drowsiness") by heart rate variability and respiratory rate variability at that time. In addition, it was also found that drowsiness could be estimated in same two stages by electroencephalogram or electrooculogram at that point. Furthermore, a technique for measuring heart rate interval and respiratory interval by the piezoelectric sensor array, just sitting in a chair, has been developed. As stated above, it has been suggested that drowsiness, which is psychological (subjective) evaluation, would be possible to link quantitative analysis of biological signals, which is a physiological (subjective) evaluation.
