Abstract

Reducing workload during ingress/egress is important to improve the usability of automotive for elderly users. In this study, we analyzed the relationships between motion features and physical features of elderly people. The muscular loads during their ingress were measured and the sitting motion, putting down pelvis to seat, caused dominant workload in ingress. The vertical axial velocity of pelvis during sitting motion was extracted as the load factor. Based on evaluation results, we proposed a new interior design and confirmed that it decreased workload and improved comfort of ingress to a certain extent.
