This kind of "magical UX design" is the most common source of me cursing equipment I interact with. A good example

When I design hardware interfaces one of my main rules is that user agency should be maximized where needed. That requires the manufacturer to trust (or better: ensure) that the user has a meaningful mental model of the device they are using. Your interface then has to honor this mental model at all times.

So build a hammer and show the user how to use it effectively, don't build a SmartNailPuncher3000 that may or may not work depending if the user is holding it right and has selected the wrong mode by touching the wrong part.
