PROBLEM TO BE SOLVED: To provide a walking posture determination device which is attached to a prescribed region and precisely determines a users walking posture.SOLUTION: The walking posture determination device includes: a means for accepting time series acceleration output by an acceleration sensor 40 according to walking of a user who wears a body part a walking duration extraction means for extracting acceleration corresponding to one walking duration from among accepted time series acceleration an integration means for integrating acceleration of one walking duration an acquisition means for acquiring a moving trajectory of the body part within one walking duration on the basis of the integrated value output by the integration means and a determination means for determining a walking posture according to a prescribed determination criterion on the basis of the acquired trajectory. The acquisition means has: an error drawing out means for drawing out error components included in acceleration of one walking duration from an integrated value of one walking duration and a correction means for correcting the integrated value of one duration by using the drawn out error component.COPYRIGHT: (C)2013,JPO&INPIT【課題】精度よく歩行姿勢を判定する。【解決手段】本体部を装着するユーザの歩行に従って加速度センサ40から出力される時系列の加速度を受理する手段と、受理される時系列の加速度のうちから、1歩行期間に相当する加速度を抽出する歩行期間抽出手段と、1歩行期間の加速度を積分する積分手段と、積分手段が出力する積分値に基づき、1歩行期間内における本体部の移動の軌跡を取得する取得手段と、取得された軌跡に基づき、所定の判定基準に従って歩行姿勢を判定する判定手段と、を含む。取得手段は、1歩行期間の積分値から、当該1歩行期間の加速度に含まれる誤差成分を導出する誤差導出手段と、導出された誤差成分を用いて、1歩行期間の積分値を補正する補正手段と、を有する。【選択図】図5
