How can I detect only hands and feet when using segments in Unity?

I tried to solve it with a skeleton somehow, but the hand and foot recognition in various movements is not well recognized, so there is a setback in content development.

It is best to use segments to detect only the hands and feet, but is there any way?

Hand and foot tags or Collider…

Hello @yjy020892
Nuitrack gives out a segment of the whole person. Separate definition of arm or leg segments is not supported.
Maybe this segment tutorial will help:
