Precision of gait indices approximation by kinect based motion acquisition

Abstract

Step length constitutes one of the important gait indices. The research described in the present paper was focused on the method of determination of the step length by means of the Kinect device. Gait sequences recorded in the Human Motion Laboratory of the Polish- Japanese Academy of Information Technology using the Vicon system played the role of the reference data. The group of six subjects participated in the experiments. Conclusions from the comparative analysis of the results of both approaches summarize the paper.
