1. The Origin of the Issue: The Clash Between Cameras That Have Penetrated Our Daily Lives and Privacy
As AI/AR glasses—including Meta’s smart glasses—stand on the cusp of widespread adoption, the issue of privacy violations caused by camera recording in public spaces has emerged as a major social challenge. In August 2026, a criminal complaint filed by a human rights group in Germany further fueled this controversy. Based on Germany’s strict telecommunications laws, which prohibit the sale of devices capable of covert recording when disguised as everyday items, this complaint raises a fundamental question for the entire smart glasses industry: Is a built-in camera truly essential?
A pure waveguide-based AR display module does not necessarily require a camera to capture its surroundings. However, visual data input from a camera is essential for advanced intelligent interactions—such as spatial computing and real-time object recognition—that are currently in demand in the market.

2. Current technological limitations and pressure from regulatory authorities
Manufacturers are striving to strike a balance between privacy protection and functionality by equipping the front of the glasses with LED indicators and other features to alert those around the wearer that recording is in progress. However, this approach has a significant drawback. Under strong direct sunlight, the visibility of the LED indicators drops significantly, and since users can intentionally block the lights, it is impossible to completely eliminate vulnerabilities in privacy protection.
This has led to criticism from human rights organizations, which argue that it ultimately forces the general public into an inescapable state of surveillance. While German authorities are currently taking a somewhat cautious stance during the preliminary review phase, they face dual pressure in the long term from deteriorating public opinion and strong regulatory bodies.
3. Three Alternative Pathways to Securing Social Acceptance
The industry is exploring improvements to the following three technical mechanisms to address privacy concerns and increase the social acceptance of these devices.
– AI glasses without a camera: This approach eliminates visual recognition capabilities and focuses on hands-free interactions, such as audio and call functions. While visual spatial computing capabilities are lost, this design retains most of the device’s practical value and can prevent privacy controversies at the hardware level. They can be worn in public in all situations, including business settings and daily commutes.
– Disabling Data Storage (AI-Only Sensor): This approach retains the camera system but completely blocks the ability to capture and save photos or videos. The camera serves solely as a “set of eyes,” capturing the real world around the user and feeding that data in real time to AI tools.
– Adoption of an advanced indicator light based on manipulation detection: Going beyond a simple LED, this approach ensures that the indicator light turns on whenever a photo or video is taken. In particular, to ensure safety, the system is designed so that the recording function is immediately disabled at the hardware level if any manipulation—such as the user covering the notification with tape or their hand—is detected.
For AI glasses to move beyond a mere niche market and establish themselves as the next-generation form factor following smartphones, they require not only advanced display and AI performance but also converged security technologies that incorporate “privacy protection” from the earliest stages of device design. Meta’s AI glasses are already on the market, and Samsung’s AI glasses are set to be unveiled in July and released by the end of the year. It will be important to monitor how consumer reactions and societal responses to the privacy controversies surrounding AI glasses unfold in the future.
On August 12, at the Display Next 2027 seminar hosted by UBI Research, the presentations covered not only recent trends in AI/AR glasses and optical technologies but also discussed the aforementioned camera-related privacy issues.
