If the user brushes their hair out of their eyes, the cursor is moved before tracking quickly corrects.
I like the idea of being perfectionistic about this, and detecting if any object (such as a hand) occludes the face, and ignore its movement, e.g. by removing tracking points.
Could detect objects by their differing optical flow... theoretically. Unless the hand comes to rest... face palm.
This is not worth it. Seriously, it's good already. It hardly interrupts for a second.
