The increasing worldwide population is accompanied by more and more cases of dementia. Healthcare systems and individuals? families are not able to bear the burden of these costs, so ICT is being used more and more for remote care. Comprehensive monitoring and feedback solutions are being developed to support people with dementia living at home, as well as their carergivers, who can follow their progress and provide them with appropriate feedback almost immediately. Such a service is being created for the FP7 EU Project Dem@Care, where multiple sensors are to be deployed to monitor a person unobtrusively, create a personalized profile of their lifestyle and behavior, and ultimately acquire higher level knowledge about their condition through intelligent processing of the data, which will correctly guide the care provided.
