  We present Open Badges, an open-source framework an toolkit for measuring and
shaping face-to-face social interactions using either custom hardware devices
or smart phones, and real-time web-based visualizations. Open Badges is a
modular system that allows researchers to monitor and collect interaction data
from people engaged in real-life social settings. In this paper we describe the
technical aspects of the Open Badges project and the motivation for its
creation.
