Experimental Study on Gaze Point Movement in Size Measurement Skill with Micrometer for Skill Succession

Since a technician usually watches the work point while confirming his hand-tip’s movement and the state of the tool and the equipment, it leads us to wonder if there exists the relationship between the gaze point movement of the technician and his skill proficiency. If the relationship is clarified, it would be effectively used in the skill education and the evaluation. In order to find out the relationship between the gaze point movement and the skill proficiency, in this research an eye camera and analysis software were used in the size measurement with a micrometer. The analysis of the gaze point movement was observed, and the relationship of the gaze point movement and the skill proficiency was discussed based on the experimental results. It was found out that the technician's gaze point movement relates with his skill proficiency. The result and discussion also showed that it is effective to put emphasis on the contact between the micrometer and the measured object, in the technical training for the size measurement with a micrometer.
