for my Master's thesis, I'm implementing custom hand gestures and have been trying to derive a pointing direction from the bone positions and orientations provided by the hand tracking. The pointing direction I end up with is very unstable and shaky though (because the bones themselves are too) and I haven't had much luck with filtering, it's either still shaky but responsive or less shaky but very sluggish. So I tried the Pointer Pose provided by the Oculus plugin and it's way smoother, but I can't really point below a certain height.
So my question is: is there some way to see how the Oculus Pointer Pose is implemented or even get access to the source code? Or alternatively a way to "adjust" the Pointer Pose to work better with different hand postures and different pointing angles?
