Hi Gareth,

there is no exactly tracked position of the wrist available. I'd suggest the following:

• With QCHT edit the default hands prefab located at Packages > QCHT Unity Interactions > Prefabs > Hands > Resources.
• Add a wrist object as a child of the hand_wrist and set the childs transform to -0.02 (depending on how low you want the wrist to be). The hand will scale for people with bigger or smaller hands - you could use yours as a reference to get a good wrist estimation.
• Do this for QualcommHandRight and QualcommHandLeft - depending on where you want to add the UI to be added.
• Note that the position of the renderer doesn't always reflect the physical position of the hands, for example when pinch interacting with an object.

• The rotation of the wrist is hard to estimate but could be possible to get as well.

Hi again,

I made a mistake sorry - there is already a wrist game object available, and it is tracked!

It seems to be offset to the right though. 

Let me know if it works or if the offset persists when using it and I will check in with the team about it.
