Character following positional tracking

Just curious, how are people handling the movement of a first-person character now that we have positional tracking? Even just sitting down in a chair, for example -- it really breaks the illusion to, say, lean over to one side or the other, then look down at your body, and see it "next to yourself." Then there are things like sitting-to-standing and vice-versa.

What tricks are people using (or planning to use) to handle this? Tracking the position and then manually via code moving the individual bones of a model to correspond to the current position? Shifting the entire character as-is? Any Unity-specific details would be great, but even just general advice or thoughts would be greatly welcomed.
