It's not possible at this time. I've thought about doing it but there are some interactions, like posing, that depend on having a tracked controller and I don't see any way to make them work otherwise.

I have Oculus Rift but don't have the Touch controllers. Is there any way to use the XBOX controller that was shipped with the Rift?
