Plain-English explanations of how smart glasses, AR displays and wearable AI work.
Guide
Camera glasses tell people nearby that they're recording with a small light on the frame. Here's what that light shows on Meta, Oakley and Snap glasses, when it stays dark, and why regulators in Europe and Australia say a light isn't enough.
Guide
Camera glasses look like ordinary frames, and their recording light is easy to miss. Here's how to tell when someone might be filming, what happens to the images, where the law protects you and what you can do if you'd rather not be recorded.

Android XR is the version of Android that Google built for headsets and smart glasses, with Gemini at its center. Here is what it does, which devices run it now, which are coming and how it compares with Apple's and Meta's platforms.
Guide
Gemini is built into Android XR, so it can see your apps and, if you allow it, your room. Here is what it does today on Samsung's Galaxy XR headset, how to control what it sees, and what Google says it will do on the audio glasses arriving this fall.
Guide
Google's Android XR runs on one headset you can buy today. XREAL's see-through Aura glasses are open for orders at launch pricing from $1,099 through the end of the year and ship in mid-November. Samsung's glasses are reported for mid-December, and glasses with a display have no date yet.
Guide
Even Realities makes camera-free glasses that show green text and graphics in both lenses, for notes, translation, prompts and notifications without taking out your phone. The G2, which replaced the G1 last November, costs $599 and adds a sharper display, four microphones and up to two days of battery.
Guide
XREAL's US store lists nine pairs of glasses, from $199 to $1,499 at regular prices, and the names don't make the differences obvious. The differences come down to a chip, the field of view, the refresh rate and whether the glasses run apps of their own.
Guide
The small LED on the front of the Ray-Ban Meta charging case reports on two batteries and also signals pairing and errors. Here's what green, orange, red, blue and white mean, and what to do about each.
Guide
Ray-Ban Meta glasses have two lights: one inside the frame that reports to you, and one on the front that tells people nearby when you're taking a photo or video. Here's what every color and pattern means.
Guide
Oura Membership costs $5.99 a month or $69.99 a year in the US. Without it, an Oura Ring shows three daily scores and little else. What the fee pays for, what it adds up to and how canceling works.
Guide
A smart ring is easier to wear to bed and lasts days longer on a charge. A smartwatch has a screen, GPS, notifications and more health and safety tools, such as an ECG app and fall detection. How the two compare on battery, health tracking, workouts, cost and phone support.
