An amateur app developer has launched a free application designed to alert individuals when Meta smart glasses are detected nearby, responding to growing concerns over the covert filming of women and girls without their consent. The app, named Nearby Glasses, scans for Bluetooth signals emitted by the eyewear and sends push notifications to users, aiming to enhance awareness and safety in public spaces.
Rising Privacy Concerns Over Meta Glasses
Meta has faced significant criticism regarding privacy and safety issues associated with its smart glasses technology. Numerous women have reported feeling "violated" and "scared" after being recorded without permission by individuals using the glasses. Domestic abuse charities have also warned that Meta's plans to integrate AI facial recognition features into the eyewear could escalate risks of harassment and stalking, particularly targeting vulnerable groups.
Developer's Motivation and Background
Yves Jeanrenaud, a 44-year-old gender studies scholar at a German university, developed the app out of frustration after reading about sex workers in the United States being secretly filmed and ridiculed. Although he learned to code as a teenager and builds apps in his spare time, Jeanrenaud was driven by the covert design of Meta glasses, which closely resemble regular eyewear, making it difficult for subjects to detect when they are being recorded.
"I thought maybe it is helpful for people to know when such a device is around them, especially because they pass quite well as regular eyewear," Jeanrenaud explained. He highlighted that unlike smartphones, which require positioning for recording, the glasses enable discreet filming without obvious gestures.
App Popularity and Limitations
Since its launch three weeks ago, Nearby Glasses has garnered approximately 78,000 downloads, primarily from women and girls concerned about their safety. The app is currently available only for Android devices and has received mostly positive feedback. However, it can only detect the presence of the glasses, not whether recording is actively taking place. This means it may trigger alerts in innocent scenarios, such as when individuals use the glasses for prescription purposes in places like public bathrooms or changing rooms.
Meta's Response and Technical Measures
Meta has addressed concerns by noting that its glasses include an LED light that activates during filming and tamper detection technology to prevent the light from being covered. A spokesperson stated that the company is aware a "small number of users" misuse the products despite these safeguards. Meta emphasized its commitment to providing safe and innovative products, with ongoing reviews to enhance smart glasses based on customer feedback and research.
However, online tutorials exist that demonstrate how to modify the glasses into "stealth mode" to disable the light, raising questions about the effectiveness of these measures. Jeanrenaud argues that responsibility lies with Meta for creating a design that facilitates covert surveillance, calling the technology a "bad thing" that society should not ignore.
Broader Implications and Regulatory Scrutiny
Recent reports have revealed that private and intimate footage captured on Meta glasses has been viewed by outsourced workers, prompting the UK's data watchdog to contact Meta regarding compliance with data protection laws. Jeanrenaud expressed dismay over these incidents, stating, "It's really horrible that this happens and that we, as societies, haven't found regulations to prevent this."
While he does not consider himself an activist, Jeanrenaud believes his app serves as a practical tool to raise awareness. "I'm not an activist. I wouldn't have the time and the spirit to engage in this discussion more. So this app is something to just help people be aware that these glasses might be around," he concluded.
