Cardboard

What Cardboard does

Cardboard turns an Android phone into a simple virtual reality viewer when used with a compatible Cardboard-style headset. It is designed for people trying mobile VR for the first time, as well as developers who need a working example of Google’s Cardboard platform. The app presents VR experiences in a split-screen format so each eye receives its own view.

Setup and viewing

The app can pair a phone with a specific viewer by scanning the viewer’s QR code. This helps match the display and lens settings to the headset in use. Once configured, Cardboard provides a straightforward way to enter supported VR demonstrations and view compatible immersive content without navigating a regular flat-screen interface.

Who it suits

This is primarily a reference and demonstration app rather than a full entertainment library. It suits students, developers, educators and curious users exploring phone-based VR with inexpensive hardware. Its connection to the open-source Cardboard SDK also makes it useful as a starting point for understanding how mobile VR applications are structured.

Cardboard’s appeal is its low hardware barrier and clear role as a practical VR sample. Results can vary with the phone’s sensors, screen and viewer quality, so it is best viewed as an entry point and developer reference rather than a complete replacement for dedicated VR equipment.
