Interacting with Unity UI using daydream controller as a pointer

Question

I am aware of GazeInputModule, which allows users to interact with Unity's UI system using head movement. I was wondering if there is a possibility to use Daydream's controller as a pointer to interact with user interface instead. Any tips or advices are much appreciated.

Answer 1

In latest GVR Unity SDK, there are sample scenes for daydream. Check them out as they are using GVRController for interaction. I assume that you are using latest Unity Daydream Preview which has built-in support for GVR. So here are the steps to follow:

1. Add GVRPointerInputModule to EventSystem :

2. Add following Prefabs in your scene:

3. Attach GVRPointerGraphicRaycaster to world space canvas and set MainCamera as event camera in canvas component:

4. And finally make sure to add enable virtual reality support from player settings and add Daydream SDK:

Note: Remove old components like GazeInputModule, GraphicRaycaster etc.

Additional:

You can change Controller's Arm model as preferred(Currently it has options of Pointer, Wrist, Elbow and Shoulder)

I hope this helps.
