Figure 4
From: Humans Use Predictive Gaze Strategies to Target Waypoints for Steering
Waypoint presentation and naming convention. Every 0.75 s a new waypoint appears (WPVIS, left panel) at a TH 2 s, apart from the occasional Gap events (WPMISS, right panel). Thus, one, two or three waypoints could be visible at one time (the previously generated waypoint WPVIS-1/WPMISS-1 is at this point a TH = 1.25 s, and the waypoint WPVIS-2/WPMISS-2 before that is still visible at TH = 0.5 s). The labels FAR, MID, NEAR designate ranges of waypoint time headways: FAR: 2.0 > TH > 1.25 s; MID: 1.25 > TH > 0.5 s; NEAR TH < 0.5 s. The labels were not visible to the participant, and the actual displays were much larger than in this figure so WPVIS was more obvious (see Movie 4 for a sample trial of the experiment).
