Cardboard SDK

The Cardboard SDK is a set of tools that developers use to create virtual reality (VR) experiences compatible with Google's Cardboard headset. It enables apps to access the phone's sensors, display 3D environments, and track head movements, allowing users to immerse themselves in virtual worlds. Essentially, it helps turn a smartphone into a VR device by providing the necessary software framework for interactive and immersive experiences, making VR content more accessible and easier to develop for a wide range of Android devices.
