  bibo_abstract:
  - Smart cities promise safer streets, smoother traffic, and more efficient services,
    enabled by dense networks of urban sensors. Yet this infrastructure, often unnoticed
    by citizens, introduces pervasive privacy risks, from tracking, profiling, and
    sensitive inferences to subtle forms of self-censorship. Despite widespread deployment,
    little is known about how the public understands and perceives these sensing systems.
    To address this gap, we present an intervention based user study (n = 172) in
    which participants are exposed to data collection by six urban sensors, including
    cameras and alternative technologies commonly framed as privacy-preserving. Participants
    encounter either the sensors alone or sensors accompanied by real-time data visualizations.
    Our results reveal widespread misunderstanding of some sensors (radar, LiDAR,
    Wi-Fi, depth, and thermal imaging sensors), particularly their capacity for identification
    and for attribute inferences such as gender or age. We also identify persistent
    misconceptions, including the belief that Wi-Fi poses privacy risks only when
    users connect to public networks. While making sensors visible and visualizing
    collected data improves privacy awareness, these measures alone are not enough
    for citizens to understand the actual risks of urban sensing. We derive recommendations
    for privacy-respecting smart city environments grounded in citizens’ informational
    needs and expectations.@eng
