I really like your videos, they have been very helpful to me. I want to save a movement (x, y, z) and then compare this with another movement (x, y, z) in real time, the idea is that the user will try to mimic the movement saved, and the system makes a calculation to find out how similar (0% ~ 100%) the motions are. My current problem is that the skeleton  from the recorded movement is different of the skeleton that is trying to mimic the movement, I'm trying to work with the idea of ​​a standardized skeleton you have any suggestions on how I can record and compare data in a standardized way?
