All the VR and AR glasses, goggles and cameras of Mobile World Congress (photos)

Mark Zuckerberg made a surprise appearance at Samsung's Mobile World Congress press event, and this insane photo was taken. It spawned a swarm of memes.

A crazy light set of VR specs, these connect with LG's new G5 phone and have their own screens. Nuts, right?

These VR glasses connect to the G5 via USB-C like a pair of headphones. Clever.

Now that you're spending so much time in VR, why not shoot some 360-degree videos to look at in it? LG's upcoming 360 Cam can shoot and help knit together 360-degree videos and let you easily share them with others, too.

We finally know the price for HTC's upcoming Vive VR system, a PC-based competitor to Oculus Rift. $799 (US) gets you a headset, but also room sensors and dual controllers. It's $200 more expensive than the Oculus Rift, but you get more in the box...and two games are included, too.

Samsung's got a 360-degree camera, too. The Gear 360 looks like an eyeball and also shoots full 360-degree video you can share with others or watch right on a Samsung Gear VR headset. No price yet, but it's aimed at being affordable enough for everyday folks who want to record their memories in surround.

Samsung's latest Galaxy S7 and S7 Edge are improved in many ways, but they still work with last year's affordable Gear VR headset. Even better, early preorders get the Gear VR and some games for free.

Samsung Gear VR debuted last fall, but Samsung's newest phones work with it, too. That's good news, because the software and apps are just taking off. Facebook announced future plans for Facebook and VR in Barcelona.

At Samsung's Unpacked Galaxy S7 event, each seat came with its own Gear VR. That's a lot of people with goggles on.

Epson's latest version of its smartglasses debut later this year, but we tried them early. The coolest part isn't the design (sorry) but its display technology. OLED makes the pop-up graphics feel more vivid, and the displays more transparent.

Why, it's Rich Trenholm getting ready for another day of work at Fujitsu's future factory! Be safe, Rich.

Never before have this many CNET editors been encased in VR headsets simultaneously. Keep following us for more from Mobile World Congress.

Eye tracking is the future of VR. Don't believe us? You will when you watch this video of Eye Tribe, one of several eye-tracking technologies currently in development, in action.
