Exploring the Impact of Wearable Cameras Through the Nearby Glasses App

Sociologist Yves Jeanrenaud has developed an Android app called Nearby Glasses to help users identify smart glasses operating nearby. He says the growing presence of wearable camera devices raises serious concerns about privacy. According to him, smart glasses represent an intrusive form of surveillance that many people may not even notice around them.

How the App Works

The app scans nearby Bluetooth signals to detect manufacturer IDs associated with popular smart glasses brands, including Ray-Ban, Oakley, and Snap Inc. When a matching ID appears, users receive an alert. The goal is to provide awareness rather than complete protection.

Jeanrenaud admits the system is not flawless. Since it identifies manufacturer IDs rather than exact product models, it may trigger false alerts. For example, a virtual reality headset could be flagged instead of smart glasses. At the same time, some smart glasses might go undetected. He encourages responsible and realistic use of the tool.

Rising Adoption and Data Protection Questions

Modern smart glasses are becoming less noticeable in public spaces. Some models include a small LED indicator to signal recording, but in bright daylight, it can be difficult to see. Manufacturers have added safeguards to prevent users from covering the LED to secretly record.

Although smart glasses have not yet sparked widespread public debate, their growing sales suggest that could change. Companies like Meta Platforms and EssilorLuxottica reportedly sold millions of units last year. With new entries expected from Google and Apple, the category may expand quickly. Reports also suggest Meta is exploring limited facial recognition features, raising further privacy concerns.

A Call for Broader Solutions

Jeanrenaud stresses that his app is not a complete solution to surveillance technology. He warns against creating a false sense of security and says stronger policies and better privacy protections are needed to address the issue effectively.

Availability and Future Plans

Nearby Glasses is available on the Google Play Store and also through GitHub, where users can find more technical details. Future updates may include support for detecting additional smart glasses brands. An iOS version is also being considered, though Jeanrenaud notes he currently lacks the development resources to build it.
