慣性センサを用いた杖歩行者の歩行特徴検出

抄録

Monitoring the walking ability in daily life is important for rehabilitation and keeping motivation for health. In this study, to develop a system to monitor the walking ability of cane users, we propose a method to detect the walking motion using an IMU sensor attached on the cane and to analyze the walking parameters for evaluating the walking ability. We detected the initial contact and terminal contact of the cane using jerk and angular jerk from the IMU sensor. We measured the walking of the cane users, and found variations of the cane angles of initial contact and terminal contact and time on ground of the cane might related to walking ability.
