Who Am I? A Design Probe Exploring Real-Time Transparency About Online and Offline User ...
summary
A system surfaces the incremental construction of ad-targeting profiles in real time using a browser extension and a mobile app and runs a two‑week field deployment with 25 participants (after a 10‑user pilot). The probe shows which website visits, place visits, and app activity add profile items, lets people remove or flag items, and produces notifications; visibility helps participants anticipate ads, prompts corrections and boundaries, and reveals that current algorithms rarely auto‑remove inaccurate or sensitive inferences.
