I am trying to make a Steam VR compatible headset, I am strapping a Nintendo Switch joycon to the headset so I can track the rotation of the headset, but I can't find a way to somehow input the values of like headset rotation or controller position into Steam VR every frame.
I found this python library that can get the rotation and position of a Switch joycon, it works, but I still can't find a way to input the values into steam without using a headset like an Oculus to begin with.
