I'm a n00b to Unity and VR, and it took me about a week to figure this out. Most of what follows is based on these Tutorials and amalgmating pieces of each

Setup

Install Unity (I'm using 2018.1.5f1 Personal)
Install Google VR SDK (I'm using GoogleVRForUnity_1.130.1)
Create Demo Project to verify it all works by following the instructions above.
Additional setting
- Under Resolution and Presentation, uncheck all except Landscape Left, this fixes a bug in the GVR SDK

Create the Scene

Add the VR Assets as described in the link above
- GvrEditorEmulator
- GvrControllerMain
- GvrEventSystem
- GvrRecticlePointer (add to MainCamera)
- GvrPointerPhysicsRayCaster (add to MainCamera)
Create a Player
- Create Menu>GameObject > Empty Object and rename to Player
- On the Player Object add a CharacterComponent
- Drag main camera to Player
- Select Camera and right click on transform and click reset
- Set Player Position to 1.8
  - we'll use each unit as a meter
Create some interaction
- Create GameObject > 3d Object > Cube
- Create a script that contains some behaviour
- Add component EventTrigger
  - allows the raycaster to detect it
- Add a script

Create Terrain and Skybox

Create Terrain
- Goto Assets >Import Package >Environment
- Goto Inspector > Click paint brush > Edit Textures
Create Skybox
- Goto Window > Lighting > Settings
- Set the Skybox Material (i use Cope)

Walking

First Person View

Add the 3 scripts below to the

Only check one of these at a time to test them all out.

Third Person View

This is the one most people will be interested in - ** controlling a Character with head movement **

Create a new Scene as above but stop at the Create Player stage
Goto Assets >Import Package >Characters
Drag the new asset Standard Assets/Characters/ThirdPersonCharacter/Prefabs/ThirdPersonController to the scene (His name is Ethan apparently)
Click the ThirdPersonController and uncheck the Third Person User Control (Script)
- We don't want to use this locomotion, we'll write out own and bind it to the ThirdPersonController
Create an Empty Object and call it CameraCradle - drag it to the ThirdPersonController
Drag the Main Camera to the CameraCradle
In the Scene View, align the view to Ethan, then Menu>Game Object>Align With Viwe
- This will match the Camera to the position you have the scene in, and will stick it there as it's a child object
Add this script to the MainCamera ThirdPersonVRController
Finally, there is a public property Character on the script above. Select the MainCamera in the Hierarchy View, and you will see it in the Inspector window. then from the Hierarchy View drag the ThirdPersonController to the Character property in the Inspector Window - binding it to the script.
Hit Play, and you should be controlling Ethan with slight head motion.
Play around with the script and you can make the motion smoother.
