Sincerely... all I can think about is not that she found a good solution to her problem, but the fact that she "achieved the same level of accuracy" (and I suppose speed).

This is not something about her capabilities, but about the limitation of current input devices regarding our hands.

This is the proof that using a touch pad with your nose is not worse that using it with your hand. There is something wrong in this: try using any real-world interface with your hand, how the shapes, the stiffness, the flexibility of any handle, pen, button, spring you interact with give you some kind of information and let you operate with a superior kind of consciousness.
