By now you can find a broad range of diverse VR glasses starting from Cardboard, the Samsung GearVR through to Oculus Rift and the new VR concept of Google called Daydream.
Each system has its own characteristics. We would like to explain the principle of VR on Google cardboard’s functionality.
Cardboard is a holding device for smartphone which has two biconvex lenses. If you start an app on your phone or open a link to an online application which supports a stereoscopically view, you’ll get a catching view through the Cardboard. The two single images which you can see on the screen of your phone will merge into a three-dimensional view through the glasses. You’re able to look around in the 3D VR world and take actions using the sensors of your smartphone. If you turn your head you’ll control the application on your phone which is held by the VR glasses.
