This study proposes a method to evaluate the influence of driver distractions caused by information processing demand of in-vehicle information systems. We focus on two types of involuntary eye movement: one is VOR (vestibulo-ocular reflex) and the other is OKR (optokinetic reflex). First, we identify the eye movement from experimental data measured without any secondary task. After that the eye movement measured with secondary tasks is compared with the identified model output. This method makes it possible to detect the influence of distractions on VOR and OKR. This study experimentally confirmed that the change of characteristics of those eye movements has relationship with the amount of information processing demand of secondary task.
