2Build Cardboard With Google’s Free, Downloadable Plans
Once you download the plans, you can trace them onto cardboard and carefully cut and score the pieces using a sharp hobby knife and other simple tools. Here is what the finished product will look like after the layout, cutting and scoring processes are finished.
3Begin Assembly and Install Your Smartphone
Once the parts are created, you can fold and assemble the parts until they form the boxy-looking Cardboard VR viewer. Several other parts are also needed, including some Velcro, a rubber band, two small magnets and some aftermarket lenses, which can be purchased online.
4Get the Cardboard App to Start Using the Viewer
Once built, the device needs the Cardboard app to work with your compatible smartphone. The Cardboard app helps you launch your favorite VR experiences, discover new apps and set up a VR viewer.
5Explore With Google Cardboard
The Cardboard app works with most modern Android phones, including the Google Nexus 4 and 5, the Motorola Moto X, the Samsung Galaxy S4 and S5, and the Samsung Galaxy Nexus. Some phones are partially compatible. Devices must be running Android 4.1 (Jelly Bean) or higher.
6Now You Can Look at VR With Cardboard
Some of the things you can do with the Cardboard app and your device include exploring the sights and destinations of Google Earth (as seen in this image of spectacular terrain), or take a virtual tour in a city such as Versailles with a local guide.
