Thanks in advance for any insight. I was wondering if anyone had a good solution for approximating body position using only the tracked headset and two Vive wands - eg: assuming we create a cube representing a users upper body/chest, is there a algorithm for approximating which direction the body is facing.
I could link the body cube to the tracked headset, but then it will incorrectly rotate when the user only rotates their head/neck (and not their body). My thought was to find the average position/rotation of the two tracked wands and extrapolate from that value, however I can see how this doesn’t solve the problem 100%. Any thoughts?
Body could be in any orientation irregardless of what these data points (hmd/con/con) look like, so they’re not useful for accurate estimations of the body orientation. You could always whip something up that assumes stuff, but it would be inaccurate in many, many cases.
Yes. That was my thought, but I was hoping for something clever that would get me close. I’m going to try and get the average rotation/position of the controllers against the average position/rotation of the headset and see if that gets me half way.
Edit: or rather parent the body cube to the headset’s position and get its rotation from the averaged y rotation of the tracked controllers and headset.
