3. people suffering of cognitive impairments –Alzheimer disease, head trauma, schizophrenia... would be able to stay at home if light assistance was provided. –But healthcare resources are scarce. –Thus relatives have to take responsibility for care. Too often, this situation then turns to an exhausting burden. Hence relatives and caregivers urge for help.

5. Smart homes Smart homes are augmented environment with brand-new networked communicating objects, embedded computers, information appliances, and sensors. They can assist cognitively impaired people and foster their autonomy. Indeed such augmented homes can become true cognitive prostheses. As well they can help caregivers to grant better care and secure residents and their relatives.

6. At the DOMUS laboratory, on-going research projects aim at building the theory and praxis of pervasive computing and tangible user interfaces (TUI) compulsory to create smart homes for cognitively impaired people. Pervasive computing enables a seamless integration of assistance in residents’ everyday life while TUI turn the whole house into a cognitive prosthesis. Prototypes are used to investigate how pervasive services and TUI can support and enhance healthcare and communication between people and caregivers. A fully-equipped experimental apartment can accommodate cognitively impaired people and their caregivers for day and night. The middleware provides for spontaneous networking, distributed and mobile computing, and sensor networks. Cognitive assistants use descriptions of activities of daily living to reason upon resident actions. They then rely on context awareness and TUI to interact with people. Finally the assistance systems remotely share information with caregivers.
