StopTracker: Real-time Monitoring of Visitor Stops and Preferences Using UWB Trajectory Streams

Published: 22 November 2024 Publication History

Abstract

Real-time monitoring of visitor behavior in venues such as museums and shops offers valuable insights into visitor preferences, hotspots, and space occupancy. Visitors typically demonstrate interest, by stopping near points of interest (POIs), such as museum exhibits, for brief durations, often on the order of a few seconds, posing challenges for localization technology and stop detection. In this paper, we present StopTracker, a framework supporting the stop-move segmentation of indoor trajectory streams, relying on Ultra-wideband (UWB) localization for the accurate monitoring of visitor stops and preferences. StopTracker is constructed using SPDstreams, an advanced variant of the popular stop-detection technique SPD, and designed to handle evolving stops. Additionally, StopTracker support the dynamic ranking of POIs. By leveraging UWB technology, StopTracker aims to provide accurate and actionable insights into visitor behavior, enhancing both visitor experience and space management.
