Last December, I wore Google Glasses while they were still under development. At this week's Google I/O developer conference, we should find out when you'll be able to get your hands on a pair. 

Until now, Meta has been the biggest tech company aiming to place a screen on your face in glasses form. But Google's entering the race with a range of smart glasses, its first return to everyday face tech since Google Glass in 2013.

This time, the focus is on AI: Gemini will be the key component that powers Google's Android XR glasses. The smart glasses will come in a wide range of designs: Warby Parker, Gentle Monster, Kering Eyewear and Samsung are all expected to have their own models. Xreal, a maker of display glasses, will also have a mixed-reality device called Project Aura.

I'll be attending Google's annual developers conference along with several other CNET colleagues. If you've thought about getting a pair of smart glasses, you'll want to see what they're all about.

Watch this: What to Expect From Google I/O: Glasses, Glasses, Glasses

All about Gemini

Google, Samsung and Qualcomm have been collaborating on Android XR, a new OS for a whole range of mixed reality headsets, AI glasses, display-enabled glasses and, eventually, augmented reality glasses. The first product of this collaboration, Samsung Galaxy XR, arrived last fall. 

Galaxy XR is very much a VR headset, but also a mixed reality computer, similar to the Apple Vision Pro and the Meta Quest 3. It runs Android apps via its Android XR OS and also has Gemini AI that can respond to voice commands and stream live video from your device's screen and the real world via its external cameras.

That on-tap Gemini assistant is exactly what will be the key app for the next wave of smart glasses. Much like Meta's Ray-Ban and Oakley glasses, which use Meta AI, Google's glasses will use Gemini and also related Gemini apps like Nano Banana and NotebookLM. 

The display-free glasses will use microphones and built-in speakers to respond to AI prompts, handle live language translation, or play music and phone calls. A camera can take photos and videos, or activate a Gemini Live mode for continuous recording and AI awareness about the world. 

An additional line of display-enabled glasses, with a color display in one lens, will show snapshots taken on the glasses, show phone notifications, play videos or even provide live assistive captioning or translation. Certain apps will also work on the glasses as extensions of what you're doing on your phone: Google Maps can show directions and maps displayed on the ground in front of you with a head tilt, or Uber can show driver status.

Three (or more) design partners

Warby Parker, Korean fashion eyewear brand Gentle Monster and European eyewear brand Kering are already official Android XR glasses partners, meaning all three will launch lines of Android XR glasses. Expect lots of designs and fashion riffs, much like how Meta's glasses partner EssilorLuxottica makes many frame designs under its Oakley and Ray-Ban brands.

Gucci smart glasses are expected via Kering, and there are sure to be more surprises. Also, Samsung is likely in the mix. Even though Samsung is already a partner helping make all these other glasses (likely by provisioning camera and display components), Samsung is reportedly going to announce its own Android XR glasses at some point, too, perhaps as soon as July at the next Unpacked event.

Google could be letting Samsung be the first mover in the space, since that's exactly what's happened with smart watches and the Galaxy XR headset over the last few years. If that's the case, Samsung's glasses could launch first, followed by the others.

Add to the mix Xreal, a manufacturer of USB-tethered display-enabled glasses, which is making its own Android XR mini-computer called Project Aura (more on that below).

Much like Google's many partnerships with watch brands years ago via Android Wear, more glasses brands could come aboard in the future as well.

A separate sort of AR glasses experience, Project Aura

The Xreal-made glasses work differently from the other smart glasses, acting more like a mini VR headset than an all-day set of eyewear. Project Aura is a specialized set of Xreal glasses with a larger display and extra cameras that plug into a processing puck the size of a phone. Wearing them (which I did last year), you can run apps and 3D experiences and even use hand tracking like a VR headset.

Project Aura runs the same apps as the Galaxy XR and uses the same chipset. It's truly a sort of shrunken-down mixed reality experience, aiming to serve as a development tool for future Google AR glasses that might connect directly to phones as well as an actual product. But it's not meant to be worn all day. Instead, like Xreal's other glasses, it's a sort of "headphones for your eyes" wearable display with audio that can extend displays out around you on the go.

The big difference: How well they'll work with Google and Android

Google's big advantage with Android XR should be how well these devices work with AI apps you might already use or with apps on your phone. On Android phones, these should feel more deeply integrated with phone controls and apps, like a smartwatch. With iOS, they should also work with Gemini services.

There still haven't been everyday smart glasses that connect deeply with the phones in our pockets, and Google's should be the first. Apple might follow next year with glasses of its own.

Google's already said phone notifications should appear as interactive widgets on the glasses, but will more apps also build deeper hooks? And will more AI be allowed beyond Gemini? For now, Google has said Gemini is the primary AI service for its glasses. But these glasses will also work with WearOS watches, too.

Will Google solve the privacy and social acceptance issues?

Meta has repeatedly run into trouble with its handling of users' personal data, and the inappropriate public use of its smart glasses' cameras has led to social media backlash. Meta's AI privacy policies are murky, and Meta's not a company that's respected for social media safety or privacy, with very good reason.

Will Google do better? It's considered more reputable, but it's also a company that already blends ads into our personal data and is increasingly swallowing up more data, like health and fitness, for its connected AI services. Google will have to explain how responsible it'll be with glasses going forward, and overcome public acceptance factors. Will the "Glasshole" moniker come back to bite it?

Price and release date unknown

We have no idea when these glasses are coming, other than "sometime in 2026." But expect more news starting at Google I/O on May 19.
