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.

Design guidelines

When developing your application for the 6DoF controllers, consider these guidelines for achieving a better user experience:

  • Lower the ray angle of the controller pointer with an offset of 15 degrees for ergonomic comfort, and to reduce the possibility of the tracking ball becoming occluded from the user’s wrists.

  • Design user interactions within the field of view of the faceplate.

  • Avoid user interactions that require hand over hand motions that cause a controller to occlude the other controller.

  • Avoid user interactions that are close to the faceplate.
