摘要

An apparatus state detector and its associates are provided to save time and effort for learning combinations of operation states of all apparatuses at home and commit fewer estimation errors even when an unknown apparatus starts operating. The apparatus state detector includes measuring means 110 that measures a physical quantity of an environment in which an apparatus is placed, feature-quantity calculation means 120 that calculates a feature quantity of the measured value measured by the measuring means 110, storage means 140 that stores in advance the feature quantity of each apparatus and an apparatus state associated with the feature quantity in a reference-apparatus entry dictionary 200, and apparatus-state detection means 130 that searches the reference-apparatus entry dictionary 200 for a feature quantity by using a feature quantity calculated by the feature-quantity calculation means 120 as a search key and detects an apparatus state based on the apparatus state associated with the retrieved feature quantity.
