From: Humans Use Predictive Gaze Strategies to Target Waypoints for Steering
Relative frequency of gaze catch (with all data pooled) at different waypoint (WP) positions. Left panel. All WPs are visible. Right panel. All WPs are visible except for the missing waypoint WPMISS (black line). The figure shows the 1.5 s period beginning (time = 0 s) from the moment that the visible WPVIS appears on the screen [left panel] or when the missing WPMISS would have appeared on the display if it were visible [right panel], and ending when the (visible or invisible) waypoint gets to TH = 0.5 s, i.e. enters the NEAR range. Black vertical lines indicate TH = 1.25 s when WPVIS or WPMISS moves from the FAR range to the MID range (and a new waypoint becomes visible in the FAR range). The yellow vertical lines indicate participant-wise crossover points where the mean gaze catch at the visible waypoint WPVIS becomes higher than at the preceding WPVIS-1 [left panel] and similarly where the gaze catch at WPMISS becomes higher than at the preceding visible waypoint WPMISS-1 [right panel]. Only data from road sections corresponding to constant curvature driving were included in the analysis (i.e. waypoints located where path curvature changes were excluded, see the Methods for details).
