Dyson's $849 Purifier Tracks Users Locally, Sidestepping Cloud Privacy Issues

Dyson's Find+Follow Purifier Cool uses computer vision to direct airflow toward users via a 17-point movement detection system—but processes all spatial data locally rather than uploading to the cloud. The approach avoids facial recognition and biometric identification, addressing regulatory pressure and user skepticism around smart home data collection. Privacy-by-design is becoming table stakes for appliance makers facing EU and US scrutiny over home device surveillance.
