>>68971285She uses VRChat and a full body tracking setup. There are many different ways you can get full body tracking, but the cheapest would probably be a Quest 2 (~$300 to $400) + Self-Built Slime-Tracker IMUs (Price Varies for DIY electronics)
At the high end, she is using a more expensive VR Headset + Valve Base Stations and HTC Vive Trackers, which can be several thousands of dollars.
I think if she's doing flips and stuff IMUs are probably better for the tracking because the base stations would get occluded at awkward angles. They need direct line of sight to the tracking points on your body.
