This. study sans to ascertain the-human saccadic visual trackingg mastics by maturing . the eye movement to the double-step stimuli Responses to simple step and d.Quble-step target_ motions were measured where the target mode and stimulus durations were randomized. To measure the eye movement the Photo-electric-Eye Monitor was constructed based on limbus tracking. The results indicate that observers represented two kind of responses (A-or B-type) depending upon the stimulus duration. The percentage of occurrances increased as the stimulus duration increased from 50 to 200 msec. When the subject responded to both target motions, the reaction time of the second saccade was shorter than that of the first. The successive visual information is to change continuously the reaction time or cancel the initial saccade.
Our results revealed that parallel data processing characteristics of the visual tracking systems and the saccadic decision-makings are influenced by the temporal relationships.
