Abstract
Walking abilities tend to be declined by getting old. The decline of walking ability causes serious problems such as falling down and breaking a bone. Moreover, it sometimes becomes one of the essential factors of death. Therefore, in this paper, we propose a system that estimates their walking abilities by using Kinect, which is an infrared depth sensor for tracking skeleton model of a user. Based on the information of skeleton model, the system analyzes elemental indices such as walking speed and step length. Then it estimates a decline of walking ability, which is used for detecting the signs of falling in the early stages.
