How did the Google Cardboard project start?
David Coz and Damien Henry at the Google Cultural Institute in Paris built a cardboard smartphone housing to prototype VR experiences as part of a 20% project. The results elicited so many oohs and ahs that they inspired a larger group to work on an experimental software development kit (SDK).
Will I AM Cardboard's headsets work with my phone?
Cardboard works with most modern Android phones. Phones need to be running Android 4.1 (Jelly Bean) or above. Ideally, they should support NFC too.
Here is a list of the phones we’ve tested that are compatible.
Can I use cardboard even if I wear glasses?
Yes. You may want to cut flaps into both sides of the viewer. There’s a fold line pre-cut into both sides of the viewer to make this easier.
What if my phone doesn’t do anything when I insert it into Cardboard?
Make sure that you have NFC turned on. Also make sure that you have the Cardboard Android app installed.
How can I test my own application without having the cardboard demo popup when I insert the phone?
The best method is to set your app to handle the NFC URL: cardboard://v.1.0.0. Alternatively, you can disable NFC in your phone’s settings.
When I try to view the Chrome VR site using Cardboard, the demo launches. How do I prevent this?
Install the Cardboard Android app and let it always handle the NFC event from the Cardboard viewer. The Cardboard app will not launch when you have another app in the foreground.
You can also disable NFC in your phone’s settings.
What are the magnets for and can I use cardboard without them?
The magnet is used for clicking inside of demos. When you pull and release the ring, your phone’s magnetometer detects changes in the magnetic field. Chrome experiments currently don’t use the magnet, but you will need it to try the Cardboard Android app.
Not all phones will be able to detect magnet pulls. You can use Cardboard without the magnet by sticking copper tape along the side of the viewer and having it come into contact with the phone screen. When you tap twice on the copper tape with your finger, the phone will react as if it had detected a magnet pull.
Headsets that display the Works with Google Cardboard badge are certified to work with Google Cardboard apps and games. The products also need to meet Google's stringent design and manufacturing standards.
All of I AM Cardboard's viewers are WWGC-certified. To learn more about our certification, check this out.
What does the NFC tag do and can I use the Cardboard app without NFC?
NFC is used to trigger the launch of the Cardboard Android app automatically. You can also start the Cardboard app from the Android launcher before putting your phone inside the viewer.
What does it mean that the VR Toolkit is experimental?
It means we won’t support the VR Toolkit at the same level or quality that we support core Android SDKs and libraries. And things may change or break as we continue working on it.
We are sharing it at this early stage to give developers the chance to experiment with it as we do.
