Imagine sitting on a crowded beach on a bright summer’s day. Someone nearby is wearing what looks like an ordinary pair of glasses. What happens when AI is secretly recording us in a setting like this? Would you notice a tiny recording light in the sunshine, or even realise the glasses had a camera?
Now imagine the same person standing behind you as you enter your PIN at a cash machine. You would probably notice if they pointed a phone camera at you. Would you give their glasses a second thought?
These are among the concerns already being raised about AI glasses. They can translate conversations, take photographs and help the wearer find out more about what they are looking at. For someone with impaired vision, they could offer valuable assistance. Yet the feature that makes them so convenient is also what makes other people uneasy: the camera goes everywhere the wearer goes.
The Camera Is Hiding in Plain Sight
We have lived with phone cameras for years. Anyone determined to record a stranger can already do it. But taking out a phone and aiming it at somebody is usually noticeable. Glasses are different. They face whatever the wearer faces, and there is no obvious gesture when someone decides to use them.
Meta says its AI glasses have a white capture light that flashes when photos or video are being taken. It says the camera will stop working if the light is covered or disabled. That is a useful safeguard, but it relies on people noticing the light and understanding it. Would you spot it from a few metres away on a sunny beach? What if you were concentrating on a conversation rather than examining somebody’s glasses?
The concern is already showing up in real life. In August, The Guardian spoke to people who said they had been secretly filmed using smart glasses. Earlier this month, Reuters reported on growing privacy fears surrounding AI glasses and other wearable devices.
Most owners will have no interest in filming strangers. But the person beside them cannot know that. A woman sitting alone in a café, a parent with children at the beach or somebody using a cash machine may simply feel uncomfortable when they cannot tell whether a nearby camera is in use.
It Does Not Have to Be a Photograph
There is another point that is easy to miss. AI glasses do not have to save a conventional photograph or video for privacy questions to arise. A wearer may ask an AI assistant about something they are looking at. To answer, the system may need information from the camera about the scene in front of it.
What else is in that scene? Perhaps a letter on the table, a computer screen in an office or somebody else’s face. The wearer may be interested only in identifying a plant or reading a sign, yet other details could be caught in view.
The ATM example is a concern, not a claim that AI glasses are routinely being used to steal PINs. The same risk exists with other small cameras. The difference is that people have learned to be wary of someone pointing a phone at them, while a person wearing glasses may attract no attention at all.
Would people eventually start asking others to remove their glasses before a private conversation? Would a receptionist need to check whether a visitor’s frames contain a camera? It sounds awkward, but these are the sorts of questions that follow when recording equipment begins to look like ordinary clothing.
Who Controls the Data?
What happens after information is captured matters just as much as whether anyone noticed the camera. Does it stay on the glasses or the wearer’s phone? Does it go to a company’s servers so that an AI system can respond? Is anything saved, and for how long? The answers depend on the particular product and feature.
Earlier this year, reports about the handling of footage from Meta’s glasses brought attention to the possibility that sensitive material could be seen beyond the person wearing the device. It is important to distinguish allegations and concerns from how every device works. Still, people are entitled to clear answers about who can access what their glasses capture.
There is a basic problem with consent, too. You can decide to buy AI glasses and agree to the company’s terms. The stranger sitting next to you cannot agree on behalf of their child. The person whose document is visible on a desk has not been asked. Nor has the person standing in front of you at the cash machine.
A privacy policy may explain what happens to the wearer’s data, but that does little for a bystander who may never know that their image or voice was involved. Data protection has to account for both groups.
AI Is Moving Into More of Our Devices
Glasses are part of a wider change. Google is developing AI features for Android that can assist with tasks across a phone. Apple has announced more capable Siri features across its devices, with support for Apple Watch planned. Some of these features are already available, while others are still being introduced.
Our phones can hold messages, photographs, location information and calendars. Watches can add details about activity and health. Giving an AI assistant access to more of this information could make it genuinely useful. It might remind us of something important at the right moment or help us find information without digging through several apps.
But each extra source of information raises a question. Can we see what the assistant has access to? Can we turn that access off? Can we delete what it has stored? And do we know when a request is handled on our own device and when information is sent elsewhere? These controls need to be understandable without reading pages of technical terms.
What Happens in Schools and Workplaces?
Public spaces are only part of the picture. Consider an office where staff handle customer records, financial information or confidential plans. Someone wearing AI glasses might have no intention of recording anything sensitive, but colleagues may still worry about what the camera can see.
Schools face a similar dilemma. A pupil or visitor might find the glasses helpful for accessibility, while other parents may object to a camera being worn around their children. A blanket ban could be unfair in some circumstances. Allowing unrestricted use could be unfair to everyone else. Clear, practical rules will be needed.
The UK Information Commissioner’s Office has identified privacy concerns around discreet wearable devices. Some venues have already restricted smart glasses because of concerns about recording without consent. That suggests businesses and public organisations may have to make decisions sooner than they expect.
We Need to Know When the Camera Is On
I can see why people want AI glasses. Translation, directions and assistance for people with disabilities are meaningful uses. But people should also be able to relax on a beach, have a private conversation or enter a PIN without wondering whether someone nearby is recording them.
Criminals are already using AI to clone voices, impersonate people and make scams more convincing. Could camera equipped glasses eventually add another tool to their arsenal? We should be asking that question now, while there is still time to set clear expectations about how these devices are used.
