PROBLEM TO BE SOLVED: To construct a low-cost and simple system simultaneously measuring (recording) brain function degradation and orthopedic degradation in order to efficiently determine physical ability of a subject.SOLUTION: A movement feature quantity observation part 110 calculates a movement feature quantity indicating the feature of the movement of the body of a subject on the basis of sensing information supplied from a physical state measuring sensor 191 which detects the movement of the body of the subject, and a physical ability determination part 120 specifies an evaluation value indicating the physical ability of the subject using the movement feature quantity of the subject, on the basis of reference information for specifying correspondence of the movement feature quantity and the evaluation value of the physical ability, which is stored in a reference information storage part 130. Also, the correspondence of a Lyapunov exponent obtained from the movement feature quantity and the evaluation value of the physical ability is described in the reference information, and the physical ability determination part can calculate a value (Lyapunov exponent) indicating the divergence of the movement feature quantity of the subject using a calculation skill of a dynamical system and specify the evaluation value corresponding to the calculated Lyapunov exponent.COPYRIGHT: (C)2013,JPO&INPIT【課題】被験者の身体能力を効率的に判定する。【解決手段】運動特徴量観測部110が、被験者の身体の動きを検出する身体状態計測センサ191から供給されるセンシング情報に基づいて、被験者の身体の動きの特徴を示す運動特徴量を算出し、身体能力判定部120が、基準情報格納部130に格納されている運動特徴量と身体能力の評価値との対応を特定するための基準情報に基づいて、被験者の運動特徴量から、被験者の身体能力を示す評価値を特定する。また、運動特徴量から得られるリャプノフ指数と身体能力の評価値との対応が基準情報に記載されており、身体能力判定部が、力学系の計算技術を用いて被験者の運動特徴量の発散性を示す値(リャプノフ指数)を算出し、算出されたリャプノフ指数に対応する評価値を特定することも可能である。【選択図】図1A
