A Study of Evaluating the Process of Mastering Skills Including Pause and Adjustment: Psychophysiological and Behavioral Evaluation Using the Information of Biological Signals and Subjective Scores

The purpose of this study was to evaluate the early process of mastering skills including pause and adjustment to reveal skill factors in producing traditional handicrafts. The information of biological signals and subjective scores were analyzed in two experiments that were performed to evaluate psycho physiological states and behaviors in the early process of mastering skills. As the results, heart rates, time-series behaviors of elecrooculogram (EOG), and wrist activities during tasks, and subjective scores before tasks reflected the difference of the product quality in the early process of mastering skills. However, each signal had advantages and also disadvantages to measure and evaluate the skill factors depending on the movement of interest. Thus, it is important to select an appropriate measurement for the movement of interest for practical use, and it is suggested that the time-series skill factors including pause and adjustment through a brief movement can be evaluated by time-series behaviors of EOG.
