Description The DOREMI project focuses on three main health aspects related to frailty in older people: unhealthy nutrition, sedentariness and cognitive decline. These aspects are the main items at the basis of the DOREMI environment: a context-aware and smart system able to learn and reason about older people, their intentions, preferences and aims. The system is able to provide feedback and propose solutions to improve their lifestyle. The specialist will be able to select and assign a personalised lifestyle protocol that will be associated to a set of game typologies (cognitive games, social games or exergames). At home, the old person will be able to select the game scenario which best corresponds to personal preferences and habits. Subsequently, the system will follow a monitor-learn loop to understand how the old person evolves according to the compliance of the assigned protocol.The effectiveness and impacts, on both users and on the healthcare system, is being tested in a set of pilots set up in Italy and UK, involving both elderly users and care providers.
