Rotate CameraRig based on Oculus Controller Rotation

I was trying to access the rotation of the Oculus controller so that i can rotate the Player Rig to create an illusion that world is rotating.

I am using SteamVR, so my code will look when i access the rotation of a right hand controller

int rightIndex = SteamVR_Controller.getDeviceIndex(Steam_VR_Controller.DeviceRelaion.RightMost);
SteamVR_Controller.Device rightDevice = SteamVR_Controller.Input(rightIndex);
Quaternion rightRotation = rightDevice.transform.rot;

now the Question How to Find out if the Controller rotated right /Left and how do i decide and rotate the player.
