This project will try to measure the impact of the use of smartphones in the teenagers’ daily lives. The students will identify the reasons that makes them “indispensable” companions in virtually every aspect of their lives, analyse the activities that interest them the most, and acknowledge potential risk factors that they need to take into account. Divided in international teams they will then discuss and try to formulate realistically applicable usage scenarios to maximize the benefits and mitigate potential risks of using their beloved devices.
