Abstract
In order to consider the efficient visual inspection method, this paper examines the difference in inspection method affecting the defects detection. Specifically, variation factors in the designed experimental model that leads subjects to four patterns of eye movement are movement of an inspection object and a way of showing. As a result, the method of moving the object quickly and widely is the way of gazing a wide range at one time involuntarily because the subjects can gaze away at the center of the object for long periods of time. In addition, it is shown that the saccade is an effective eye movement for visual inspection capturing a defect as a sense of incongruity as the result of considering the feature of eye movement.
