PROBLEM TO BE SOLVED: To solve problems for example, about each kind of sense stimulation factor, each kind of a biological signal measured and induced by the stimulation, and a kind and intensity of sensitivity generated on a human being, a useful method for explaining mutual association and causal relation has not been practically used.SOLUTION: A sensitivity estimation device comprises: a first acquisition part for acquiring a feature amount of a stimulation factor for stimulating a sense organ of a living body； a second acquisition part for acquiring a feature amount of a biological signal detected from a living body； and an estimation part for, based on a result of learning relationship between the feature amount of the biological signal when the living body is stimulated by a stimulation factor, and sensitivity information indicating sensitivity of the living body when the living body is stimulated by the stimulation factor, estimating the sensitivity information when the living body is stimulated by a new stimulation factor.SELECTED DRAWING: Figure 1【課題】各種の感覚刺激要因と、この刺激によって誘起され計測される各種の生体信号、そして人間に生じる感性の種類や強度について、相互の関連や因果関係を説明する有力な手法は実用化されていない。【解決手段】感性推定装置は、生体の感覚器を刺激する刺激要因の特徴量を取得する第１の取得部と、生体から検出される生体信号の特徴量を取得する第２の取得部と、刺激要因の特徴量と、生体が刺激要因により刺激されたときの生体信号の特徴量と、生体が刺激要因により刺激されたときの生体の感性を示す感性情報との関連性を学習した結果に基づいて、生体が新たな刺激要因により刺激されたときの感性情報を推定する推定部とを備える。【選択図】図１
