Nearby Glasses is an Android app that alerts you when smart glasses are detected nearby. It utilizes company identifiers embedded in the Bluetooth data transmitted by these devices.

Be Aware of False Positives

There is a possibility of false positives, including notifications from devices like VR headsets. Therefore, it is advisable to exercise caution when approaching individuals wearing glasses, as they may simply be wearing regular eyewear, despite the app's alert.

Hidden Surveillance in Plain Sight

Smart glasses are increasingly integrated into everyday life, yet they can often be indistinguishable from conventional eyewear. The app identifies smart glasses by scanning for their Bluetooth identification (specifically, Company Identifiers in the BTLE advertising frame, ADV_INV) and sends notifications when such devices are within a configurable distance. This allows users to take appropriate action based on the proximity of smart glasses.

Personal Privacy

The developer regards smart glasses as a significant violation of personal privacy, dismissing their pervasive reliance on user consent. They view this technology as a disturbing advancement, primarily associated with the generation of vast amounts of objectionable content. While some smart glasses models include a small LED indicator to signal when recording is in progress, users can easily disable this feature, raising serious ethical concerns. Despite manufacturers' assurances regarding privacy safeguards, they often evade accountability for the misuse of these devices. In addition to their recording capabilities, smart glasses have been implicated in enabling instant facial recognition, which can be activated out of the box, further intensifying concerns about surveillance and the potential for abuse.

Works by Identifying Distinctive Bluetooth Signature

Nearby Glasses detects the unique Bluetooth signature emitted by smart glasses. When these glasses are detected, the system sends a push notification to users, alerting them that someone wearing them may be nearby. This feature is designed to enhance users' awareness and connectivity, enabling them to choose to distance themselves from the area if they wish.

For testing, we were only able to see if our neighbor's VR headset was detected (yes), as I do not know anyone with a pair of smart glasses.

Geek Verdict

Nearby Glasses will help to notify you that smart glasses are in your vicinity, so you can leave the area. However, as the developer warns, harassing an individual under the assumption that they are wearing a covert surveillance device can constitute a criminal offense. In some cases, this offense may be considered more serious than the act of using such a device itself. It is important to be aware of the laws in your area regarding this issue, and seeking legal advice is recommended for clarity and guidance.
