how can I move camera with joystick in VR

[fsayeh]

Actually I have a building and I want to walk around it with joystick in VR with google cardboard.
I don’t have any movable objects, I want the camera moves around my building.

I did a simple house and for move the cam i put the first person controller prefab then in player settings->input i changed the horizontal and vertical plane in the option keyboard to joystick, and selected the 9joystick option, it works, but i have a problem, when i see the north, it walks with joystick up like always, but when i turn my head to see west, i’ve to put joystick left to walk forward, not joystick up as always, if you want, you can try this form and if you can fix this thing tellme please
