Abstract: A computer system is configured to: obtain, from a user, biological data including a biological signal of the user and motion data including a motion signal relating to a motion of the user and store the biological data and the motion data in the storage device; generate a biological signal time series and a motion signal time series through use of the biological data and the motion data in any time range; correct, through use of the motion signal time series, the biological signal time series to a corrected biological signal time series having reduced influence of the motion of the user; and estimate emotion of the user through use of a first biological feature amount calculated from the corrected biological signal time series, and store an emotion estimation result of the user in the storage device.
