Claim One:
1. A state recognizing device for recognizing a plurality of states of a space, comprising: a first filter unit that performs a filtering process on a time-series signal, which is obtained as a result of performing remote measuring on the space, in accordance with a first cutoff frequency so as to allow a signal component deriving from movement of a biological organism to pass through; a second filter unit that performs a filtering process on the time-series signal in accordance with a second cutoff frequency, which is lower than the first cutoff frequency, so as to allow a signal component based on biological information of the biological organism to pass through; an amplitude-component extracting unit that extracts a first feature quantity related to an amplitude component from a signal passed through the first filter unit and the second filter unit; a frequency-component extracting unit that extracts a second feature quantity related to a frequency component from a signal passed through the first filter unit and the second filter unit; a model storage unit that collects an aggregate of feature quantity-state data, each piece of the feature quantity-state data including amplitude information corresponding to an output of the amplitude-component extracting unit, frequency information corresponding to an output of the frequency-component extracting unit, and one of the plurality of the sates for the amplitude information and the frequency information; and a recognizing unit that recognizes a state of the space by using the first feature quantity, the second feature quantity, and the aggregate of feature quantity-state data.
