Chatdao Septham Greetings & Welcome to Microsoft Q&A forum!

Did you check Azure Kinect body tracking joints page already?

A skeleton includes 32 joints with the joint hierarchy flowing from the center of the body to the extremities. Each connection (bone) links the parent joint with a child joint. The figure illustrates the joint locations and connection relative to the human body.

The following table enumerates the standard joint connections.

Also, See references where we are having active discussions on this topic:

Hope this helps. Do let us know if there are any further queries.
