We currently do not officially support Windows Mixed Reality (WMR) headsets. There are cases where some users have made it work in Sansar, but we do not guarantee that the headset will work 100% well with Sansar.
Yes, you can use the Xbox One or Xbox 360 game controller. See Game controller buttons for more information.
