Abstract
The activity of low vision people is multifarious because of difference of their visual function, ability of walking and consciousness of mobility. The characteristic of low vision's visual function and activity is not considered enough, when the environment is improved. We have to consider not only relationship between low vision person's visual function and activity but also environmental factors. The purpose of this study is to apply the concept of ICF (International Classification of Functioning, Disability and Health) to evaluation of activity of low vision people. Especially, we consider the relationship between visual function, activity and environmental factors. As a result, the public transportation facility was important for activity of low vision people who were able to walk alone.
