In order to improve living space for stable walks by elderly people, this paper discussed assessment of living space with unique-shaped support objects. Four evaluation indices expressing capability of balance recovery corresponding to the support object were derived based on directionality of generative force by human's upper extremity and directionality of reaction force depending on surface shapes of the objects. Experiments were carried out to (1) obtain the parameters necessary to calculate the proposed indices and (2) carry out organoleptic evaluation of the support objects. Compared to the results obtained in these experiments (1) and (2), effects of the proposed indices were discussed, and an effective index among the four for evaluating the effect of the support objects was clarified. Assessment of a support object using the index was shown as an example.
