This is really cool! Full body tracking in a dedicated box. It's a ToF sensor (Kinect 2 style) with on-board ML processing. Same concept as using an iPhone for ARKit face tracking (not just a camera, but also all the smarts).
I always want streaming to be as friction-free as possible, so the idea of having to put on trackers never sat well with me... this looks like a great alternative! ✨️
