description To provide a method to execute calibration accurately even for a user having difficulty standing up straight by himself or herself.SOLUTION: A plurality of inertia measuring sensors 2 for detecting three-axis acceleration and angular velocity are attached to the upper body part, the thigh part, and the leg part of a user U to measure an action of the user U; the user U is caused to be seated in a reference posture in which the upper body part and the leg part are parallel to each other, and the thigh part is orthogonal to the upper body part and the leg part; and calibration of the plurality of inertia measuring sensors 2 is executed on the basis of the output of the plurality of inertia measuring sensors 2 acquired when the user U is seated in the reference posture.SELECTED DRAWING: Figure 4 【課題】自身で身体を直立させることが困難なユーザであっても、キャリブレーションを精度良く行える方法を提供する。【解決手段】ユーザUの動作を計測するためにユーザUの上体部、大腿部及び下腿部に、3軸の加速度及び角速度を検出する複数の慣性計測センサ2を取り付け、上体部と下腿部とが互いに平行をなし且つ大腿部が上体部及び下腿部に対して直交する基準姿勢をもってユーザUを座らせ、基準姿勢をもってユーザUが座った状態で取得した複数の慣性計測センサ2の出力に基づいて複数の慣性計測センサ2のキャリブレーションを行う。【選択図】図4
