AI Summary

Meta has filed a patent for an AI system capable of continuously monitoring a user's voice, biometrics, and device usage to infer emotional states throughout the day. The system could run on smart glasses, phones, or smart home devices, logging emotional data with timestamps, location, and activity context. While not currently implemented in any product, the technology raises significant privacy concerns due to its extensive data collection, including voice tone, pupil size, blink rate, and app usage. The EU AI Act has already restricted emotion-inference technologies in workplaces and schools, and similar consumer-facing systems may face regulatory scrutiny.
