USense: A people-centric opportunistic sensing tool

People-centric sensing has been emerging due to the integration of the most varied sensors in personal devices. The goal is to infer individual behaviour following a participatory or opportunistic, non-intrusive, sensing methods. USense is a non-intrusive sensing tool able of contextualising the user's social behaviour based on information, such as social proximity and relative distance, captured via the usage of short-range wireless technology (Wi-Fi Direct, Bluetooth). This paper describes the USense tool in a realistic scenario, which is the basis of the proposed demonstration
