Health Prevention for the Aging Population in Smart Cities: the City4Age Project

City4Age is a research project co-funded by the European Commission as part of the H2020 Programme. Data from smart cities and sensors and other sources, are utilized for the prevention of Mild Cognitive Impairment (MCI) and frailty of aged people. Data are "interpreted" to understand behavior and behavior changes, identifying decaying and possibly risky situations. Highly individualized messages are used to "persuade" individuals to healthier behaviors, as a background action or triggered by worrying detection data. The solutions developed by the project (data modeling, the tools, the databases, etc.) are general, so that they could be reused for different segments of population and for different purposes.
