The iCare research project aims at developing and evaluating solutions that help to maintain the independence of people with an increased need of care by means of smart and mobile information technology. The existing solutions for a self-determined living in old age have not been integrated into an overall concept that focuses on the needs of people with increased need of care, for example people suffering from dementia, and there caregivers. In the iCare research project we do so and have developed the DeSearch network and the iCare Bots (in the variant as CamBot or ScanBot).
