| Abstract(in English) | We modeled fluid transfer field at gas sensor responses, and analyed changes in the indoor environment. The results of this analysis indicate that transfer characteristics can be extracted by blind deconvolution using the low time windowing of complex cepstrum, and inverse filtration of the thus estimated space transfer characteristics allows us to extract drive signals proportional to the amounts of human activity. In an experiment in which the indoor environmental changes during daily life were measured, and drive signals were obtained. These results suggest that fhe detection of human actions can be improved by eliminating the residual components from the gas sensor responses. |
