"Nearby Glasses" App Launched to Detect Wearable Recording Devices

A new mobile application, "Nearby Glasses," has been launched to detect smart glasses and other wearable recording devices in proximity. The application aims to address concerns regarding the potential for non-consensual recording by individuals using camera-equipped eyewear, such as Meta's Ray-Ban smart glasses. Its functionality relies on scanning for wireless signals emitted by these devices, providing users with notifications upon detection.

App Functionality

The Nearby Glasses app operates by continuously scanning for Bluetooth signals from devices manufactured by companies including Meta (and Oakley) and Snap. Upon detecting a Bluetooth signal that contains a publicly assigned identifier unique to these manufacturers, the application sends an alert to the user. Users also have the option to add custom Bluetooth identifiers to expand the range of detectable wearable devices.

Developer's Motivation

The application's creator, Yves Jeanrenaud, stated that his motivation for developing the app stemmed from observations of smart glasses being used in various contexts, including immigration raids and for filming sex workers. Jeanrenaud also cited Meta's decision to implement face recognition as a default feature as a contributing factor.

The developer characterized the application as an act of "resistance against surveillance tech."

Smart Glasses and Privacy Concerns

Meta's Ray-Ban smart glasses, which are capable of capturing photos and videos, have initiated discussions regarding privacy since their introduction. The design of these glasses resembles standard eyewear, making them difficult to distinguish from conventional frames. They include a small LED indicator that activates during recording; however, some assert this light can be inconspicuous. Smart glasses facilitate hands-free recording, which may be less obvious than recording with a smartphone.

The development of Nearby Glasses reflects broader discussions regarding privacy in the context of widespread recording technology. Privacy laws in various jurisdictions have not consistently adapted to these technological advancements, leading to ambiguities concerning consent and recording regulations. Technology companies have stated that their products include privacy safeguards and that users are responsible for complying with local recording laws.

Technical Considerations and Limitations

Experts indicate that detection applications like Nearby Glasses may encounter technical difficulties in precisely identifying specific smart glasses models amidst various wireless devices. The efficacy of these detection methods is dependent on the wireless signals emitted by the glasses and the necessary proximity for detection.

During testing, the Nearby Glasses app successfully detected Meta's virtual reality headsets, which utilize similar Bluetooth identifiers, indicating a potential for false positives. The app was also able to detect Apple devices when a specific Bluetooth identifier was manually added. However, during a test in a city neighborhood, no smart glasses wearers were identified.

Future Developments

Jeanrenaud is reportedly adding new features to the application. There has also been expressed demand for an iPhone version of the app, which would depend on the developer's availability.
