@misc{Barrat2008, abstract = { In this paper we present an experimental framework to gather data on face-to-face social interactions between individuals, with a high spatial and temporal resolution. We use active Radio Frequency Identification (RFID) devices that assess contacts with one another by exchanging low-power radio packets. When individuals wear the beacons as a badge, a persistent radio contact between the RFID devices can be used as a proxy for a social interaction between individuals. We present the results of a pilot study recently performed during a conference, and a subsequent preliminary data analysis, that provides an assessment of our method and highlights its versatility and applicability in many areas concerned with human dynamics. }, author = {Barrat, Alain and Cattuto, Ciro and Colizza, Vittoria and Pinton, Jean-Francois and den Broeck, Wouter Van and Vespignani, Alessandro}, interhash = {7868941dd765a5a1f02df5cbfe49c9ef}, intrahash = {f1fb2322336e3f1c7336b0d475311d42}, note = {cite arxiv:0811.4170 }, title = {High resolution dynamical mapping of social interactions with active RFID}, url = {http://arxiv.org/abs/0811.4170}, year = 2008 }
