| Research Abstract |
To support the safe life of the elderly living alone, surveillance technology based on acoustic sensors was researched. The approach is converting acoustic events in everyday life into original symbols, and recognizing situations and living conditions by data mining of time series patterns of the symbols. In this research, we developed the following technologies: multiple microphone arrays; footsteps recognition; people tracking; acoustic novelty detection; acoustic event categorization; acoustic feature extraction; behavioral situation recognition from long term life-log data. We also collected life behavioral data of the elderly in a model house for evaluation.
