Abstract: A method includes: acquiring, via a network, biogas information at multiple timings and time information corresponding to time at each of the multiple timings, wherein the biogas represents a concentration of furfural of a user acquired by a sensor that detects the furfural discharged from a skin surface of the user; obtaining reference information representing a lower limit of a normal range of furfural per unit period of time, using a memory storing the reference information representing the lower limit of the normal range; determining a stress time period during which a concentration of the furfural of the user is less than the lower limit of the normal range, based on the acquired biogas information; and outputting time period information indicating the determined stress time period to an information terminal of the user.

Abstract: In order to objectively grasp a stress state of a user and to prevent postpartum depression, biological gas information is acquired via a network, where the biological gas information indicates a concentration of hexadecane of the user and is obtained by a sensor that detects hexadecane released from a skin surface of the user. From a memory storing information including an upper limit of a normal range of the concentration of hexadecane per unit period, the information indicating the upper limit of the normal range is read out. When a frequency in the unit period with which the concentration of hexadecane of the user exceeds the upper limit of the normal range is determined to have an increasing tendency based on the biological gas information obtained during a pregnancy period of the user, the information related to stress of the user is output to an information terminal of the user.

Abstract: A device control system including a wearable device and a server. The wearable device includes a device that ejects a fragrance material, a biological sensor, and a computer. The computer transmits biological data to the server, receives a first control signal, and causes the device to eject a fragrance material upon receipt of the first control signal. The server includes a computer. The computer receives the biological data, estimates users emotion from the received biological data, and in a case where it is determined that the user has positive emotion by using a result of the estimation, (i) transmits the first control signal to the wearable device and (ii) transmits, to an aroma device, a second control signal for causing the aroma device to eject a fragrance material at a predetermined timing.
