Abstract
The purpose of this study was to evaluate time-series behavior in EOG(Electro-oculogram) signals as a quantitative evaluation method about process of mastering skills for producing traditional crafts. Time-series behavior in EOG signals during the tasks were analyzed as the basic skills for producing lacquer wares. The 3-minute tasks were performed 5 times a day for 5 days. EOG electrodes were attached obliquely horizontal level and measured during painting canvases. Two groups were classified. One was a quantity group whose painting scores were increased linearly. And the other was a quality group whose painting scores were not increased. There was a relationship that the rhythm of EOG period was shortened and the stability of EOG time-series behavior increased according to increasing the task speed in the quantity group. And there was a relationship that the stability of EOG time-series behavior increased according to increasing the task speed and the task quality in the quality group. These results suggests that a process of mastering skills can be evaluated quantitatively by analyzing time-series behavior of EOG signals during a task.
