In this work, we introduce our approach for detecting and presenting anomalies of daily routines in assisted living environments. The proposed concept addresses the challenges of detecting, deducing and presenting the provenance, if such anomalies occurs. With our assistive knowledge-and model-based approach, users reach higher levels of awareness about their own lives and potential irregularities. Thereby, we consider the compelling issues of detecting causes of anomalies and also presenting them without overburdening the user. A prototypical implementation substantiates our approach and introduces our forthcoming user study.
