Abstract
We have shown that the driver distraction can be quantitatively estimated from the vestibulo-ocular reflex (VOR) that is a type of involuntary eye movement. However, the optokinetic reflex (OKR) was not considered in the previous models. Here, we developed a new model with both VOR and OKR. Using the new model, we investigated the effect of mental workload and aging on the involuntary eye movement as well as the driving performance. In this study, we evaluate driver distraction of younger group (age 20–59) and older group (age 60 and above) while driving with/without mental workload. Total 12 participants (6 in each group) who drive on a daily basis participated in the experiment to evaluate driver distraction. As expected, we succeed in applying VOR and OKR models to evaluate driver distraction while driving. Based on that, the effects of mental workload and aging on driver distraction were analyzed. The results indicate that the older group shows worse performance, especially under the distracted driving condition.
