Study on Relation Between Human Behavior and Skill Level in Human Interface

摘要

In this research, the human behavior and skill level in small-hole drilling has been quantitatively evaluated and their relationship has been discussed. The behavior has been evaluated by operational and physiological measurements such as operator's body motion, cutting force, hand wheel rotation, blood pulse period, respiration period, electromyogram of forehead (EMG), electroencephalogram (EEG). The skill has been evaluated from task time, task error and tool breakage. The experimental results showed that there are strong correlations between the behavior measurements and skill level. It was also confirmed that the skilled operators make their body movement small, and keep their respiration rate low and constant.
