To accurately estimate a user's emotion.SOLUTION: A computer system acquires biological data including user's biological signals and motion data including motion signals regarding the user's motion from a user, creates a biological signal time sequence and a motion signal time sequence using biological data and motion data in an arbitrary time range, corrects the biological signal time sequence to a corrected biological signal time sequence in which influence of the user's motion is reduced using the motion signal time sequence, and estimates the user's emotion using a biological feature amount calculated from the corrected biological signal time sequence.SELECTED DRAWING: Figure 6 【課題】高い精度でユーザの情動を推定する。【解決手段】計算機システムは、ユーザから、当該ユーザの生体信号を含む生体データと、当該ユーザの運動に関する運動信号を含む運動データとを取得し、任意の時間範囲の生体データ及び運動データを用いて、生体信号時系列及び運動信号時系列を生成し、運動信号時系列を用いて、生体信号時系列を、ユーザの運動の影響が低減された補正生体信号時系列に補正し、補正生体信号時系列から算出される生体特徴量を用いてユーザの情動を推定する。【選択図】図６
