Google Cardboard

Google Cardboard, announced in Google I/O on June 25, 2014, is a cardboard cut-out smartphone mount. With a smartphone inserted, Google Cardboard allows the user to have a Virtual Reality experience by holding it close to his or her face.

While Google Cardboard requires a smartphone with stereoscopic display software, this simple and affordable device is constructed with lenses, a magnet, a piece of hook-and-loop fastener and a rubber band. With no official manufacturer, Google has listed the schematics and instructions for the device on its website. Users can either construct one themselves or purchase them from a number of unofficial vendors.

Apps such as immersive games and concert experiences are available in the Google Play store. Developers familiar with OpenGL can use Cardboard SDK for Android to rapidly create VR apps for the device.
