[Unity] Placing HTC Tracker on wrist

[Isato]

I would like to detect and register the tracker placed on the wrists on Unity just like the person besides the robot in the following website.
However, I couldn't find "wrist" on the menu (see the attached screenshot). How can I do this?

That is the steam interface shown(used when running software) versus a unity3d menu(used when creating software), so there will be differences.

I would gather that "held in hand" or "elbow" would be correct choices to get compatible pieces of software to run to detect it that way. 

If you want to author software yourself, and see that specific menu, download unity3d and install the steamvr plugin which has that. 
It's worth noting that steamvr's plugin has been mostly superceded with unity's own wrapper https://docs.unity3d.com/2018.3/Documentation/ScriptReference/SpatialTracking.TrackedPoseDriver.html and https://docs.unity3d.com/ScriptReference/XR.XRNode.html which fixes a number of issues. The xrnode.HardwareTracker would be the appropriate choice, and the app itself would need to configure where this would be mapped to.

Thanks,
