Meta’s Holy Grail AR Smart Glasses Have One Big Puck-Shaped Problem

Meta’s “Phoenix” XR smart glasses might not be out yet, but if there’s one thing we already know, it’s that when they are, they’ll need a little assistance on the computing side. That help will likely come from a puck that you’ll have to carry around with you—a puck that we may have just gotten our first glimpse of. A new mockup render shared on X by Noridoesvr, who claims to have seen prototypes of Meta’s hardware—a rumored pair of lightweight XR glasses in a goggle-like form factor—offers more insight into what Project Phoenix’s puck will entail. First look at the compute unit for Meta's 2027 Project Phoenix VR glasses! I modeled this based on physical prototypes I’ve seen. Note the waistband clip and the cooling exhaust on top. The design will likely change, but this represents some variants currently being tested. https://t.co/M0KgoTPlEU pic.twitter.com/IJPszfLfJg — Nori 🦈 (@noridoesvr) February 6, 2026 At first glance, the compute puck looks pretty manageable. It’s not oversized, it looks relatively innocuous, and it even has a waistband clip so you can cart it around without pockets. It sounds like no big deal, but it might also be the one thing that turns people off from Meta’s AR glasses. As promising as the future of AR glasses suddenly is, cramming a whole computer into a pair of frames that rest comfortably on your face is no easy task. Miniaturization is rough, and at a certain point, maybe even impossible. Shrinking down a computer to fit on your face butts against Moore’s Law pretty directly—you need the power to do all sorts of stuff in a form factor that’s light and ergonomic, but you need to do all of that without burning a glasses-sized hole through someone’s head (thermals are no joke). As a workaround to all of those issues, Meta seems interested in offloading the compute to a puck, which is a solution that Google and Xreal are also interested in pursuing with Project Aura. Google and Xreal’s partnership was recently showcased in December and relies on a wired puck to enable a computer-like experience where people can use Android apps on a big virtual screen. Think Vision Pro, but in a much, much, smaller form factor. Framed that way, the value proposition for tethered smart glasses makes sense. The Vision Pro might be an impressive technical feat, but wearing one for long periods of time sucks because of the weight and the resulting not-so-great battery. Tethered smart glasses take all the weight and put it… not on your face, which is objectively a win for your nose and forehead. In other ways, though, both of these form factors share the same problem. The Vision Pro, like Meta’s Phoenix smart glasses and Project Aura, also needs its own kind of puck—a battery pack. To shed weight, the Vision Pro connects to a battery that you have to carry along with you, along with a wire. It’s not ideal, but that’s the tradeoff for a face-worn computer that does more than mirror your connected device’s screen. It becomes even less ideal when you consider the puck is on your body. As you may have noticed, there appears to be an exhaust fan on the compute puck, which could presumably serve to direct heat away from your body. It’s hard to tell, but based on the renderings, it might be pointing up? That would be a strange choice, and there’s a chance that what I’m seeing as the correct orientation is actually the opposite. Here’s to hoping this thing doesn’t blast hot air at your torso. No matter which way you spin it, there are lots of downsides to using a puck for computing, and those downsides might be a little too much for some. The worst part is, if you’re waiting around for Google, or Meta, or eventually Apple to shrink the form factor down and fit it into glasses sans puck, you might be waiting forever. There’s no guarantee that the puck is a problem that can be solved, and Meta’s upcoming Phoenix smart glasses might be further proof. For now, we can at least enjoy the head-to-head between Meta and Google when they’re eventually released, which could be sometime in 2027 and late 2026, respectively. May the best XR video glasses with a portable computer puck win, I guess?
