New algorithms for vr?

Question

Algorithms

Hello, I have a simple question, but I can't find it.
Question.
There are technologies for converting the form, specifically human hands, into bones on a computer.
I came across a couple of months ago (an article or video) in this area that talked about two new algorithms.
1. Converts quickly with fingers that are covered by others, however not accurately when crossing them.
2. Slowly converts yet accurately restores even when fingers are crossed and behind others.

We need to find information about it.
PS Troll and write that "Google banned me?" no need to ask. Could not find.
Thank you in advance.
