Figure 4: Case 3’s eye-gaze data for two pedestrians at the large right eccentricity (median filtered with a 5-frame window, 60 Hz). Left: Lateral (top) and vertical (bottom) eye position for a +14° pedestrian. Bottom left graph shows three distinct downward saccades, the last of which caused his upper quadrant to obscure the pedestrian for approximately two seconds (Pedestrian Envelope shows the vertical angle subtended by the pedestrian). Right: Although making four downward saccades, the pedestrian is detected as illustrated by a rightward saccade (~277 seconds after drive start) and the horn-press that quickly followed.
