New app warns Android users of nearby smart glasses

As reported by The Register, a new Android application called Nearby Glasses has been released, designed to alert users if smart glasses, such as the Ray-Ban Meta AI Glasses, are in their vicinity. Developed by Yves Jeanrenaud, a deputy professor at Darmstadt University of Applied Sciences, the app utilizes Bluetooth Low Energy advertising data to detect the presence of these devices.

The Nearby Glasses app scans for specific manufacturer identifiers broadcast by smart glasses. While MAC addresses and service UUIDs can be randomized, the manufacturer company IDs are mandatory and immutable in BLE advertising frames. Jeanrenaud notes that the app may produce false positives from other Meta Bluetooth devices, like VR headsets, and advises caution. The app's GitHub repository includes a warning against harassing individuals based on the app's detection. Incidents of altercations and misuse of smart glasses for non-consensual recording and harassment have been reported, raising concerns about privacy, especially with potential future features like facial recognition.

The emergence of this app highlights growing public unease regarding the privacy implications of wearable technology. While recording in public is generally legal, the use of smart glasses, particularly those capable of collecting biometric data or audio, can lead to legal risks under state wiretapping laws and privacy regulations. Meta maintains that its glasses have an indicator light for recording and that users are responsible for legal compliance. However, the ability to disable these indicators and the potential for misuse underscore the ongoing debate surrounding consent, privacy, and the responsible development and deployment of smart eyewear.
