A fundamental part of studying human mobility is to detect dwelling. When the authors dwell at places such as their homes, the supermarket or the local park, they are not necessarily still or stationary, but move around in a confined area. Most, but not all, of their significant places are indoors, which hampers the detection using GPS. In this paper, they discuss three different sensor sources and their idiosyncrasies when used for dwelling detection. In particular, they use geolocation services based on collected WiFi fingerprints and show that they may be used complementary to GPS information.
