Research interests

Representation, protection, analysis of mobility data. Mobility data grasp the movement of entities , e.g. humans, animals, assets, in a reference space, opening up to the analysis of individual and collective behavior . Focus on:

  • mobility pattern conceptualization and analysis

  • mobility data modeling

  • location privacy and location-based access control

  • applications in: animal ecology, museums, geologya

Paper @ IEEE Percom 2022. Fine-grained stop detection in UWB-based trajectories, F. Hachem, D. Vecchia, M.L. Damiani, G.P. Picco. Teaser @ https://www.youtube.com/watch?Paper v=8ZNcMFzp0AI.

Abstract: Ultra-wideband (UWB) localization enables user tracking with high spatio-temporal resolution, whose exploitation for detecting higher-level mobility patterns is largely unexplored. We study whether i) existing detection techniques, developed for coarser-grained localization, apply also to UWB trajectories, and ii) the quantitative extent to which this enables finer-grained analyses. We focus on the well-known stop-move pattern, and offer a concrete use case of capturing visits in a real museum. We contribute a novel metric suited to the high UWB spatio-temporal resolution and use it to evaluate representative techniques. We deploy a UWB system in a 25x15 m2 museum area and base our analysis on 70000+ positions and 200+ ground-truth stops. These are very close in space and time, yet results confirm very accurate spatio-temporal estimation in the vast majority of cases.
