It is a low-cost platform introduced and developed by Google to increase the reach VR technology as far as possible.

As the name suggests, Google Cardboard is an HMD (head-mounted display) which is made up of foldable cardboard.

Google came up with a free application “Cardboard” which is compatible with your budget smartphones.

But, the app will only be compatible if your smartphones consist of Gyroscopic Sensor.

Why choose Google Cardboard?

When it comes to Virtual Reality, the biggest hurdle is the availability of the resources to create VR content.

But, Google sorted our problem. Google till now provides 3 SDKs (software development kits).

One of them is for Android OS. This SDK uses Java as its coding medium. For game development, Google provides Unity which employs C# as the coding medium.

The last, 3rd SDK is released for the iOS operating system.

Also, from 2016, Google has provided us the flexibility to use Javascript and HTML coding to create VR content.

Moreover, the SDKs supports Spatial Audio. It will basically interpret the outside voice or noise and simulate it anywhere in the 3D space around you.

We can even experience the virtual realm over the internet. Google implemented this using WebGL. Smartphones which supports WebGL can run the VR content.

Initially, on the launch, the Cardboard App offered Cardboard Demo, 360 Video Channel, and the Street View. But the later updates have upgraded the app a lot.
