Abstract:
[Problem] To provide a state recognizing device capable of more accurately recognizing the state in a space.
[Solution] Provided is a state recognizing device characterized by comprising: a first filtering unit that passes through a signal component caused by movement of an organism by filtering, using a first cutoff frequency, a time series signal obtained by remote measurement in a space; a second filtering unit that passes through a signal component based on biological information of the organism by filtering the time series signal using a second cutoff frequency that is different from the first cutoff frequency; an amplitude component extracting unit that extracts a first feature set pertaining to the amplitude component from the signal that passes through the first filter and/or the second filter; a frequency component extracting unit that extracts a second feature set pertaining to the frequency component from the signal that passes through the first filter and/or the second filter; and a recognizing unit that recognizes the state in the space using the first feature set and the second feature set.
