How do I control character using HMD?

How do I simply move my main character using the head movement from the Rift? For example: I would like to tilt my head to the right, which would activate the physics force/impulse that I applied to my character the same way I would if I hit the corresponding “balance-right” key that I mapped to the keyboard. Control BP for character using physics is setup and works, and is in third-person. Everything else works correctly, just can’t figure out what node or process to use to enable HMD movement to directly influence movement of character. Advice, examples, tutorials, witty quips and sarcastic-yet-useful comments are welcome and appreciated, been stuck on this for over a month now and the sadness is weighing me down. :frowning:
