An innovative Android application called Nearby Glasses, developed by Yves Jeanrenaud from Darmstadt University of Applied Sciences, alerts users about nearby smart glasses using Bluetooth Low Energy (BLE) technology. The app detects manufacturer identifiers associated with smart eyewear, including Ray-Ban Meta AI Glasses, and notifies users when such glasses are in proximity. However, it may produce false positives due to other Bluetooth devices from the same manufacturer. The app's launch coincides with growing concerns about non-consensual recording, highlighted by incidents like a viral altercation on a New York subway involving smart glasses. Meta has stated that their glasses have an LED light that indicates when recording is occurring, but this indicator can be disabled. Legal experts warn that while video recording in public is generally allowed, collecting biometric data raises privacy concerns, and various state laws may require consent for audio recordings. Recent courtroom incidents have also underscored the contentious nature of wearable technology.
