高齢者の安定歩行支援のための住環境評価を目的としたバランス復帰特性に基づく単一支持物の評価指標の提案

抄録

In order to assess living space for assisting stable walks by elderly people, this paper proposed an evaluation index for single support object which is calculated from four fundamental measures expressing capability of balance recovery corresponding to the support object, derived from the directionality of generative force by human’s upper extremity and the directionality of reaction force corresponding to the surface shapes of objects. Experiments were carried out to (1) obtain the parameters necessary to calculate the fundamental measures and (2) carry out organoleptic evaluation of the support objects. Compared to the results obtained in these experiments (1) and (2), effects of the indices were discussed, and an effective index among the four for evaluating the effect of the support objects was clarified and proposed. Assessment of sample support object using the proposed index was shown as a demonstration.
