This demo is a simple scene that uses the headset with gaze input (without a controller). The "game" consists of locating the cube and clicking the viewer's trigger button. Compatible with a traditional Cardboard viewer.

Controller Demo Scene

File: Assets/Gvr/DemoScenes/ControllerDemo/ControllerDemo.unity

This is a demo of how to use the controller. Running this scene on an actual phone requires an Android N build running on a supported VR device (for example, a Nexus 6P), and a controller or controller emulator.

If you want to run the scene in the Unity Editor only, you only need a phone with the controller emulator installed.

For instructions on how download and set up your controller emulator, see the information about controller support in https://developers.google.com/vr.

Summary:

The controller phone can be running any version of Android supported by the controller emulator app (Lollipop and above, at the time of this writing).
Install the controller emulator app on the controller phone.

To run the scene in the Unity Editor:

Make sure you have the Android SDK installed, and that the adb command is in your PATH environment variable.
Connect your controller phone to your computer with a USB cable.
Verify that you are correctly set up by typing adb devices on a terminal. That should list your device.
Click Play on the Unity Editor.

To run the scene on your headset phone:

You will need two phones, one for the headset and one to use as a controller emulator.
The headset phone must be running an Android N build.
Set up a WiFi hotspot on your controller phone, and have your headset phone connect to it (remove your SIM card if you want to avoid mobile data charges).
Make sure you've gone through the necessary setup steps to enable controller emulator support on your headset phone (in particular, verify that Enable Controller Emulator is enabled in Google VR Services Settings).
Launch the Controller Demo scene on the headset phone.

How to play:

Point at cubes using your controller or controller emulator.
Hold the controller's touchpad as you move your controller to drag the cubes around the scene.
Repeat until happiness is achieved.

Note: the controller can only be used on a supported VR-enabled Android device (at the time of this writing, the Nexus 6P) running a VR-enabled build of Android N (the latest Android N developer preview build). On any other device or platform (e.g. unsupported Android device, iOS, desktop, etc), the controller API will still be present, but will always report the controller as being disconnected.
