November 6, 2019 update:
  • There's a new open source Cardboard SDK for iOS and Android NDK that offers a streamlined API, improved device compatibility, and built-in viewer profile QR code scanning. A corresponding Unity package (SDK) is planned for a future release. We recommend that all developers actively building for Google Cardboard migrate (iOS, Android NDK) to the new Cardboard SDK.
October 15, 2019 update:
  • The Daydream View VR headset is no longer available for purchase. However, you can continue to use the existing Google VR SDK to update and distribute your apps to the Google Play Store, and make them available to users in the Daydream app.

Daydream Controller

The Daydream controller combines a simple, intuitive user interface with 3DoF functionality for expressive design. All Daydream apps require the Daydream controller so as a developer you can design experiences for a standardized input model.

Some common ways the Daydream controller can be used are:

  • Ray-pointer: Interacting with 2D UI in worldspace. For example, choosing files from a 2D file-selector in a media app or selecting icons from a 2D in-app inventory screen.
  • Gesture-based input: Using the controller as a proxy for a physical motion, such as throwing a frisbee or swinging a baseball bat.
  • Movement: Using the controller to allow the user to move around the environment, for example, through the use of teleportation.
