Abstract
A traffic accident is a disturbing matter caused by a rise of the recent vehicle diffusion rate worldwide. Therefore, estimation of driver's action unrelated to driving may help to reduce traffic accidents. This paper proposes a novel method to estimating driver's action unrelated to driving by measuring signals from air mass flow sensor placed on the seat belt. A previous study tried to estimate driver's action by measuring signals from pressure distribution sensors placed on the driving seat. However, the previous study was concerned about a large difference of accuracy rate when the drivers reseat. We focus on the seat belt since there is very little change of wearing form via three stationary points. As a result, the accuracy rate when drivers reseat with our proposed method came over 90%. Consequently, proposed method is quite effective and useful to estimate driver's action.
