Promoting a safe return to university campuses during the COVID-19 pandemic: Crowdsensing room occupancy

We describe the work behind a privacy-preserving, crowdsensing approach that promotes social distancing upon the return of students to University. Our main motivation is enabling visualizations that predict room occupancy based on the number of connected devices to particular access points, via anonymous reports about these predictions, and via an unenforced booking system that allows users to communicate their intents about room use. © 2021 ACM.
