Abstract

With the aim of developing a method for evaluating driver distraction based on the difference between simulated and observed eye movements, we integrated a vestibulo-ocular reflex (VOR) model and an optokinetic reflex (OKR) model. On the basis of 2 × 2 factorial design analysis (VOR model only and VOR+OKR model; with and without visual stimulus), we confirmed that the VOR+OKR model showed a better performance than the VOR model, with a smaller mean-square error. We also conducted an experiment that used an n-back task to simulate mental workload while driving. The mean-square error between the simulated and observed eye movement became larger in the presence of mental workload. This result suggests that the VOR+OKR model could be applied in the evaluation of driver distraction.
