This one tracks limbs, https://dl.acm.org/doi/abs/10.1145/3447993.3482857 https://dl.acm.org/doi/abs/10.1145/3447993.3482857 & https://techxplore.com/news/2021-11-winect-tracks-3d-human-poses.html https://techxplore.com/news/2021-11-winect-tracks-3d-human-p... > Our system tracks free-form activity by estimating a 3D skeleton pose that consists of a set of joints of the human body. In particular, Winect first identifies the moving limbs by leveraging the signals reflected off the human body and separates the entangled signals for each limb. Then, our system tracks each limb and constructs a 3D skeleton of the body by modeling the inherent relationship between the movements of the limb and the corresponding joints. Our evaluation results show that Winect achieves centimeter-level accuracy for free-form activity tracking under various environments. ~200 papers for VR + CSI, ~30 for 2022, https://scholar.google.com/scholar?hl=en&as_sdt=40005&sciodt=0%2C10&cites=4354757827101869878&scipsc=1&q=virtual+reality https://scholar.google.com/scholar?hl=en&as_sdt=40005&sciodt...
