歩行軌跡より求めた"つまずき"の危険度に関する研究

Abstract

Analysis of the relationships between human walking and level difference in buildings was conducted to find out ways to prevent tripping accidents. Natural walking of subjects was observed to identify the trajectory of tiptoe, and the result was examined from the viewpoint of potential tripping risk due to an obstacle on the floor. The findings are : walking speed slows down as subjects get older; and, if the subject does not notice the presence of an obstacle, risk of tripping can be estimated from the research result.
