装着型加速度・角速度センサーを用いた雪道歩行解析(J14-2 人体計測と制御,J14 ヒューマン・ダイナミクス)  [in Japanese] Gait Analysis on Snowy Road Using Wearable Sensors for Acceleration and Angular Velocity  [in Japanese]

In a cold region like Hokkaido having continuous snowfall during winter season, people are often found being slipped or fallen down while walking in the snow covered road. This sometimes causes serious injuries or fracture of bones especially to elderly people, and many of them become bedridden. In the traditional way of gait analysis, limited place and range of experiment were the constraints of measuring device. In this study, gait analysis was performed by using wearable sensors to obtain acceleration and angular velocities without the constraints of place and range of experiment. The experiment was carried out on indoor flat road, indoor stairs, paved sloping road (having slope of 5 degrees), snowy flat road and quasi-snowy flat road. The features of gait on the snowy flat road were obtained from the acceleration values.
