Driver Gaze Behavior Is Different in Normal Curve Driving and when Looking at the Tangent Point.

ABSTRACT: Several steering models in the visual science literature attempt to capture the visual strategies in curve driving. Some of them are based on steering points on the future path (FP), others on tangent points (TP). It is, however, challenging to differentiate between the models' predictions in real-world contexts. Analysis of optokinetic nystagmus (OKN) parameters is one useful measure, as the different strategies predict measurably different OKN patterns. Here, we directly test this prediction by asking drivers to either a) "drive as they normally would" or b) to "look at the TP". The design of the experiment is similar to a previous study by Kandil et al., but uses more sophisticated methods of eye-movement analysis. We find that the eye-movement patterns in the "normal" condition are ind
