Google Daydream

From Wikipedia

Daydream is a virtual reality (VR) platform developed by Google for use with its Google Daydream View virtual reality headset and Android Nougat, the seventh major version of the Android mobile operating system. It was announced at the Google I/O developer conference in May 2016, with the first VR headset released on November 10, 2016.

Contrasting with Google’s first VR platform, Google Cardboard, Google Daydream is built into the Android operating system starting with the release of Android 7.1 Nougat. The platform includes both software and hardware specifications, designating compatible phones “Daydream-ready”.
