末梢皮膚温揺らぎを用いた温冷感計測

抄録

Control of indoor thermal environments in accordance with people's preferences makes an　important contribution to comfort. To keep a suitable temperature environment, we tried to estimate a subject's thermal sensation using biologic signals. We focused on peripheral skin temperature to reduce the number of sensors in order to make an objective thermal sensation measurement system suitable for use in daily life. First we carried out an experiment involving alteration of environmental temperature to reveal the relation between peripheral skin temperature and thermal sensation vote. Next we made a thermal sensation processing algorithm and evaluated the algorithm. When thermal sensation indices estimated by our algorithm were compared with the subject's vote, error of mean squares was l or less in most cases. As a result, the possibility of thermal sensation measurement using peripheral skin temperature is confirmed.
