PROBLEM TO BE SOLVED: To provide a walking position measurement method for measuring a walking position of a subject by calibrating the influence due to distortion of a magnetic field.SOLUTION: A walking position measurement device includes a magnetic field generation process of generating a magnetic field from a magnetic field generation unit having a transmission coil a magnetic field detection process of attaching the magnetic field detection unit as a magnetic field sensor to each of the left and right leg parts of the subject and performing the magnetic field detection as a magnetic field detection value for each transmission coil in the magnetic field detection unit and a calculation processing unit for calculating a distance between the magnetic field generation unit and each magnetic field detection unit in a calculation processing unit and computing a left-and-right walking width based on the received magnetic field detection value of each transmission coil. A calibrated walking width Sn of the subject is obtained from the following formula provided that an actual measured walking width value being the measured walking width of the subject is defined as Sr, a normal walking distance as Dp, and an actual measured walking distance being a total of the distances actually walked by the subject as Dr. Sn=Sr×(Dp/Dr)COPYRIGHT: (C)2016,JPO&INPIT【課題】磁界の歪みによる影響を校正して被験者の歩行位置を計測する歩行位置計測方法を提供する。【解決手段】送信コイルを備える磁界発生部から磁界を発生させる磁界発生工程と、磁界センサとしての磁界検出部を被験者の左右の脚部に各々取り付けて、磁界検出部にて送信コイル毎の磁界検出値として磁界検出を行う磁界検出工程と、受信された各送信コイルの磁界検出値に基づき、演算処理部にて、磁界発生部と各々の磁界検出部との間の距離を算出して左右の歩幅を演算する演算処理工程と、を有する。実測された被験者の歩幅である実測歩幅値をSr、規定歩行距離をDp、被験者が実際に歩行した距離の合計である実測歩行距離をDr、とした場合、校正された被験者の歩幅Snは次式により求める。Sn=Sr×(Dp/Dr)【選択図】図1
