Abstract: A method for estimating an emotional state is executed by a computer and includes acquiring an amount of change of a cerebral blood flow of a user from a reference time, acquiring an amount of change of a heart rate of the user from a reference time, and outputting a signal indicating that the user is in an excited state in a case where the amount of change of the cerebral blood flow is smaller than a first threshold value and the amount of change of the heart rate is larger than a second threshold value.
