We are very familiar with Google applications and gadgets. Google already launched headset with low cost. The name of this headset is Google Cardboard. These headset are not designed or not official manufacturer by Google. This company made of a list of parts and gave instructions on their websites. They announced the people to manufacture the cardboard themselves from the given list of parts. They also provided the instructions to the assembling of cardboard.
Some of the parts included in manufacturing of that product are :
magnets,
- a hook,
- a rubber band,
- an NFC tag,
- a piece of cardboard cut in to defined shape,
- 45 mm focal length lens.
Google also provided extra instructions for large scale manufacturing organizations, they also provided extra kits with less cost.
Once the kit is assembled, a smartphone is inserted in front of the lenses removing the rubber band. A Google Cardboard–compatible app splits the smartphone display image into two, one for each eye. Many adjustments also made automatically after switching the display in to the lens. The lenses then create a 3D image with a great view. The first version of Cardboard could fit phones with screens up to 5.7 inches (140 mm) and used magnets as a simple input button that required a compass sensor in the phone. An updated design released at Google I/O 2015 works with phones up to 6 inches (150 mm) and replaces the magnet switch with a conductive lever button that generates a touch event on the phone's screen for better compatibility across devices.
Google provides two software development kits for developing Cardboard applications, both using OpenGL: one for Android using Java, and one for the game engine Unity using C#. Third-party apps with Cardboard support are available on the Google Play store and App Store for iOS. In addition to default Cardboard apps, there are Google Chrome VR Experiments implemented using WebGL.
