Abstract
In quality inspection, which is the final stage of the manufacturing process, there is an operational manual on how the object should be inspected. In this study, we followed the gaze of the workers to search for the "way of looking" at the objects to be inspected, which is not described in the manual. As a result of experiment, we found a difference of the reciprocating eye movements between skilled worker and the beginner. It is suggested that this indicates a way of looking at inspection that has been unconscious until now.
