The European FP7 project CONFIDENCE - Ubiquitous Care System to Support Independent Living is developing a system that will monitor the health conditions of the elderly in real-time based on radio tags placed on the human body. In case of health problems, the system will issue a warning to the user and an alarm to the caregiver if necessary. This way the elderly should gain the needed con dence and security to continue their independent participation in society, thus reducing costs for medical services and burden to the working age pop- ulation. The paper describes work in progress of the reconstruction and interpretation subsystem and presents encouraging results in complexfall detection scenario.
