Google Cardboard is VR’s Gateway Drug | WIRED
There’s no reason not to try Cardboard now. It’s cheap, it’s easy, it works with your phone. It’s still a million miles away from the best VR demos out there; Oculus, HTC’s Vive, and Project Morpheus all blow Cardboard out of the water—which they should, because they’re not made of cardboard. But Cardboard more than accomplishes what it’s supposed to: It transports you.

Google’s Cardboard Design Lab teaches VR with (what else) VR | Engadget
Google debuted its larger and more robust Cardboard VR headset at I/O yesterday, now it needs some apps that actually run on it. However, designing a program in a virtual 3D environment is quite different than designing one to run on a 2D touchscreen. That’s why Google has also released the Cardboard Design Lab, an app that teaches you the basics of VR design from within a VR environment. The program runs through 10 fundamental design aspects — from “Using a Reticle” and “Keeping the User Grounded” to “Guiding with Light” and “Gaze Cues” — all from within the confines of the Cardboard headset. It won’t transform you into an VR hacking wizard overnight (as it’s not designed to) but CDL will give neophyte coders a solid overview of what they’re getting themselves into. And while the lessons learned here can just as easily be applied to designing for the Rift as Cardboard, the app is currently only available on Android.

Google’s Cardboard VR Now Works (Very Well) With iPhone | TechCrunch
Google’s Cardboard VR app first appeared last year at I/O 2014, but the initial version was somewhat limited in terms of device support. A new version released this year works with devices with screen sizes ranging up to 6 inches, but the more exciting news for many might be that it now also works with iPhone.

The new Cardboard for iOS app is available in the U.S. store now, and includes the same demo apps, as well as the same QR-code based pairing process to make sure it’s optimized for whichever generation of headset you have. Cardboard for iOS is a free download, and works with iPhone 5 and up.
