Driving Around Bends with Manipulated Eye-Steering Coordination

This article reports on a study that investigated the connection between drivers' gaze positioning and steering behavior when negotiating bends. In the study, the driver's point of gaze was directed toward a target situated in the vicinity of the tangent point (TP). The TP is a region known to attract a significant amount of ocular fixations and thought to provide some useful input for anticipatory steering. The orientation of gaze relative to the TP was manipulated and the resulting steering behavior was compared to that obtained with a free-gaze strategy. The study's results showed that constraining the driver's eye movements did not impair steering behavior. On the contrary, the continuous tracking of the fixation point promoted smoother steering control, irrespective of the position of that point. This confirms earlier research that previewing the road curvature by tracking a distant point contributes to the stability of steering. The authors note that these results indicate that continuously looking at the TP or further inside the bend yielded a deviation of the trajectory. This is consistent with the hypothesis that drivers look inside the lane boundaries to determine the future path.
