Abstract

Driver fatigue is contributed by various factors. One possible factor of driver fatigue is head movements and another is visual discomfort caused by visual blur. During whole-body vibration, vestibule-ocular reflex (VOR) function decreases visual blur. However, the VOR function may change based on the driver state. This study aims to clarify which factor has a relationship for subjective driver fatigue during long term driving, magnitude of head movements, changing characteristics of VOR functions, or consequent visual blur. A multiple regression analysis showed that visual blur had a greater relationship with driver fatigue than head movements had.
