From the advent of personal computers and later the internet, ICT- based systems have been used to assist healthy living. (Chatterjee & Price, 2009) describe four generations of such technologies: The first generation are “prescriptive” systems in the late 1960s that mainly support the one-on-one persuasion between a health care provider and the patient. Second generation: “descriptive” systems, starting in the mid 1980s, are web based systems aiming to provide information and content to the patient. The third and current generation are “environmental” systems from around year 2000 which integrate sensing and information exchange to infer a user’s present state and impact change. The authors envision a fourth generation of “automated” systems in which human intervention is minimal and which are able to provide recommendations to the user in a fully automated and highly personalized way.
