Visualization of Interpersonal Communication using Indoor Positioning Technology with UWB Tags

Abstract: In conjunction with a social gathering held on a university campus, the movement of attendees were tracked within the venue for approximately two hours using a UWB indoor positioning system, in order to visualize their interpersonal communication. Network and community analyses were performed on attendee interaction data, and the evolution of communities over time was further investigated through repeated community analysis at different time points. Furthermore, recognizing the influence of distance thresholds on defining contact, we discussed how varying these thresholds affected the resulting network structure and community analysis outcomes. This study confirmed that the temporal evolution of communities identified through community analysis broadly corresponded with the visually observed groupings of participants using the UWB indoor positioning system.
