This book describes the multidisciplinary approach needed to tackle better aging. Aging populations are one of the 21st century’s biggest challenges. National health systems are forced to adapt in order to provide adequate and affordable care. Innovation, driven by digital technology, is a key to improving quality of life and encouraging healthy living. Well-designed technology keeps people empowered, independent, and mobile; however, despite widespread adoption of ICT in day-to-day life, digital health technologies have yet to catch on. To this end, technology needs to be effective, usable, cheap, and designed to ensure the security of the managed data. In the era of mHealth, mobile technology, and social design, this book describes, in six sections, the collaboration of polytechnic know-how and social science and health sectors in the creation of a system for encouraging people to engage in healthy behavior and achieve a better quality of life.
