Zusammenfassung:PROBLEM TO BE SOLVED: To provide a posture operation detector capable of detecting where is the center of operation.SOLUTION: A posture operation detector includes a first detector 2 attached at a forearm section of a subject and a second detector 3 attached to a finger. With the first detector 2, a first detection sensor 21 and a second detection sensor 22 composed of an acceleration sensor, a gyro sensor, and a geomagnetic sensor are provided at a position separated for a certain distance, and by these sensors 21 and 22 a motion state of the forearm section and a center of rotation are calculated. A calculation unit 4 calculates posture and motion state of the forearm section, the posture and the motion state of the forearm section are removed from a value detected by the second detector 3, and motion only by the finger and that of the forearm section are separated.SELECTED DRAWING: Figure 4 【課題】どこを中心に動作しているのかを検出できるようにした姿勢動作検出装置を提供する。【解決手段】被験者の前腕部に取り付けられる第一検出部2と、手指に取り付けられる第二検出部3を設ける。この第一検出部2では一定距離離れた位置に、加速度センサやジャイロセンサ・地磁気センサからなる第一検出センサ21第二検出センサ22を設け、これらのセンサ21・22から前腕部の運動状態や回転中心などを算出する。そして、算出部4で前腕部の姿勢や運動状態を算出し、第二検出部3で検出された値から前腕部の姿勢や運動状態を除去し、手指のみの運動と前腕部の運動を分離する。【選択図】図4
