Abstract—In the area of smart homes context aware systems play a key role towards adaptive smart environments. Our research currently focuses on the combination of positioning information with model-based approaches to recognize residents activity patterns (e.g. ”breakfast routine”), in order to adjust the environment accordingly (e.g. light, sound and temperature). We employ a semantically enriched IFC building model for spatial analysis tasks and an ontology based component to reason about typical activity patterns in order to derive reliable situation estimations. Living Place Hamburg, a fully functional smart home, allows for evaluation of our results under real life conditions. Keywords—smart home, context awareness, low level context reasoning, spatial analysis, ontology based context reasoning I.
