PROBLEM TO BE SOLVED: To easily realize sensory rating.SOLUTION: A sensory function storage part stores sensory correspondence information to which a myoelectric potential and a sensory rating value are made to correspond. A sensory rating value estimation part estimates the sensory evaluation value on the basis of the measured myoelectric potential and the sensory correspondence information.COPYRIGHT: (C)2013,JPO&INPIT【課題】容易に官能評価を実現できる。【解決手段】官能関数記憶部は、筋電位と官能評価値とを対応付けた官能対応情報を記憶する。官能評価値推定部は、測定された筋電位と前記官能対応情報に基づいて、官能評価値を推定する。【選択図】図8
