You can use the Patch Editor to bind the movement of a scene object to a face tracker, so the object moves with the face.
To try this out:
Connect the Rotation port on the face tracker patch to the input port in the patch representing the object’s Rotation property.

Whenever your head moves, the object should move with it:
You could use the 3D Position port in the face tracker patch instead. Connect it to a patch representing the Position property of an object, to change it’s position without rotating the object.
