As described above, although the present invention has been described by the embodiments, it should not be understood that the statements and the drawings that form a part of this disclosure limit the present invention. Various alternative embodiments, examples and operation techniques will be apparent to those skilled in the art from this disclosure.
例えば、既に述べた実施の形態において、生体情報処理部２は、取得した生体情報に対して信号処理することにより、ユーザーが快適と感じていることを意味する快適レベルを算出し、増加及び減少を反転させて、判断部３に入力するようにしてもよい。
For example, in the embodiment described above, the biological information processing unit 2 performs signal processing on the acquired biological information to calculate a comfort level which means that the user feels comfortable, and increases and decreases it. May be inverted and input to the determination unit 3.
また、既に述べた実施の形態において、生体情報処理部２は、図４に示すように、快適感及び覚醒感を指標とした２次元心理モデルによって馴化レベルを算出するようにしてもよい。２次元心理モデルにおいて、快適感を示すＸ軸の正領域は「快」、負領域は「不快」を示し、値が大きくなるほど快適度が増加し、小さくなるほど不快度が増加することを示す。また、覚醒感を示すＹ軸の正領域は「覚醒」、負領域は、「鎮静」を示し、値が大きくなるほど覚醒度が増加し、値が小さくなるほど鎮静度が増加することを示す。２次元心理モデルにおいて、第１象限がリフレッシュ状態、第２象限がイライラ状態、第３象限が退屈状態、第４象限がリラックス状態を示す。生体情報処理部２は、２次元心理モデルを用いて評価した、生体情報処理部２が取得した生体情報に対応するユーザーの心理状態を、馴化レベルとして判断部３に出力する。判断部３は、生体情報処理部２によりユーザーの心理状態がイライラ状態又は退屈状態と評価されている場合において、馴化レベルが閾値を超えたと判断すればよい。
Further, in the embodiment already described, the biological information processing unit 2 may calculate the habituation level by a two-dimensional psychological model using the sense of comfort and the sense of alertness as indices as shown in FIG. 4. In the two-dimensional psychological model, the positive region of the X axis indicating a sense of comfort indicates "pleasure" and the negative region indicates "discomfort", and the larger the value, the more comfortable, and the smaller the degree of discomfort. The positive region of the Y-axis showing a sense of awakening indicates "awakening" and the negative region indicates "sedation", and the larger the value, the more the degree of awakening and the smaller the value, the more the degree of sedation. In the two-dimensional psychological model, the first quadrant indicates a refresh state, the second quadrant indicates an irritability state, the third quadrant indicates a bored state, and the fourth quadrant indicates a relaxation state. The biological information processing unit 2 outputs the psychological state of the user corresponding to the biological information acquired by the biological information processing unit 2 evaluated using the two-dimensional psychological model to the determination unit 3 as a habituation level. The determination unit 3 may determine that the habituation level exceeds the threshold when the biological information processing unit 2 evaluates the user's mental state as an frustrated state or a bored state.
上記の他、本発明はここでは記載していない様々な実施の形態等を含むことは勿論である。したがって、本発明の技術的範囲は上記の説明から妥当な特許請求の範囲に係る発明特定事項によってのみ定められるものである。
