Zusammenfassung: | To estimate an emotion of a subject accurately, with a small amount of calculation on the basis of biological data.SOLUTION: An emotion estimation system comprises: an acquiring unit for acquiring biological data from a biological sensor; a neutral reference setting unit for generating a Poincare plot which is formed of a point group in two axes on the basis of the biological data in resting of a subject, out of pieces of biological data, then calculating a barycenter position of the Poincare plot and setting the calculated position as a neutral reference; a threshold setting unit for setting a first threshold to a prescribed position in an origin direction of the Poincare plot to the neutral reference, then setting a second threshold to a prescribed position in an opposite direction of the origin direction of the Poincare plot; a calculation unit for generating the Poincare plot on the basis of the biological data of an inspection object for a prescribed period out of the pieces of biological data, then calculating a barycenter position of the Poincare plot as an inspection point; and an estimation unit for estimating an emotion of the subject on the basis of the inspection point.SELECTED DRAWING: Figure 3
【課題】生体データに基づいて少ない計算量で高精度に対象者の感情を推定する。【解決手段】実施形態の感情推定システムは、生体センサから生体データを取得する取得部と、生体データのうち、対象者の安静時の生体データに基づいて2軸における点群からなるポアンカレプロットを生成し、その重心位置を算出して中立基準として設定する中立基準設定部と、中立基準に対して、ポアンカレプロットの原点方向の所定位置に第1閾値を設定し、ポアンカレプロットの原点方向と逆方向の所定位置に第2閾値を設定する閾値設定部と、生体データのうち、所定時間分の検査対象の生体データに基づいてポアンカレプロットを生成し、その重心位置を検査点として算出する算出部と、検査点に基づいて対象者の感情を推定する推定部と、を備える。【選択図】図3 |
