Abstract

Awakening and sleeping are recognized as human behaviors by a gas-sensor output using a fuzzy reasoning. The gas sensor is made from a tin oxide and is sensitive for various gases. The sensor output has a daily periodical pattern. The pattern descends gradually during sleeping and ascends suddenly as of awakening. Recognition is performed using the characteristics of the pattern. At that time, the min-max compositional method is adopted. There are only six rules in this system.
