Walking distance estimation of a walker user using a wrist-mounted IMU

摘要

This paper presents an algorithm for estimating walking distance using a wrist-mounted IMU for continuous rolling case of a walker user. The walking distance is estimated through the hip joint displacement in a planar plane based on an inverted pendulum walking model. Our main contribution is that we can estimate the movement distance of the hip joint from the wrist-mounted imu without any calibration process. The accuracy of the proposed method was compared to our previous work through 20 m walking experiments.
