Eye movement reflects a viewer's visual information process. This study examines whether eye-movement responds to the viewer's cognitive load. It is already known that pupil size and blink can use as an indicator of mental workload. Saccades are rapid eye movements to turn a fovea to a focusing target. For this process, saccade was extracted to observe viewing process.
