In the calculation step, the level of comfort of the user is calculated on the basis of the heat balance information and first reference information. The first reference information indicates the relationship between the heat balance information and the level of comfort. In the output step, information relating to the level of comfort is outputted.

INFORMATION PROCESSING SYSTEM AND INFORMATION PROCESSING METHOD
One embodiment of the present invention provides an information processing system. This information processing system comprises a thermoelectric conversion unit and a signal processing unit. The thermoelectric conversion unit is configured so as to generate a thermal gradient by exchanging heat with a device and is configured so as to generate thermoelectric power on the basis of the thermal gradient. The signal processing unit comprises an acquiring unit and a detection unit. The acquiring unit is configured so as to acquire the thermoelectric power. The detection unit is configured so as to detect, on the basis of the thermoelectric power, an abnormal operation of the device accompanied by heat generation.
