PROBLEM TO BE SOLVED: To provide a device for measuring a joint angle of a human body capable of eliminating error accumulated various causes such as noise.SOLUTION: The joint angle measuring device is characterized by carrying out a joint angle detecting processing for detecting the joint angle based on the outputs of a first joint angle detecting sensor arranged in a first supporting part mounted on one of limb bodies of a user sandwiching a joint and a second joint angle detecting sensor arranged in a second supporting part mounted on the other of the limb bodies sandwiching the joint, and a joint angle correcting processing for correcting the joint angle detected based on the first angle detecting sensor and the second angle detecting sensor to a joint angle corresponding to a predetermined positional relation in the case it is continuously detected that the first supporting part and the second supporting part is in a predetermined positional relation for a predetermined time.COPYRIGHT: (C)2013,JPO&INPIT【課題】人体の関節角度を計測する装置において、ノイズなど様々な要因によって蓄積される誤差の解消を行う。【解決手段】本発明に係る関節角度測定装置は、関節を挟んでユーザーの肢体の一方に装着される第1支持部に設けられた第1関節角度検出用センサーと、関節を挟んで肢体の他方に装着される第2支持部に設けられた第2関節角度検出用センサーの出力に基づいて関節角度を検出する関節角度検出処理と、第1支持部と第2支持部が所定位置関係にあることを所定時間継続して検出した場合、第1角度検出用センサーと第2角度検出用センサーに基づいて検出される関節角度を、所定位置関係に対応する関節角度に修正する関節角度修正処理を実行することを特徴とする。【選択図】図7
