Since the human body is governed by the thermoregulation principle to balance the heat flux between the ambient thermal condition and the body itself, skin temperature has a significant role in maintaining the physiological principle. Therefore, the author investigated the potential use of skin temperature and its technical parameters to establish a thermal sensation. This seminar discusses optimally combined skin temperature information collected from selected body areas, and examines how much reliable and applicable the designated skin temperatures are for estimating individual thermal sensations.
