It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form.

I find that soccer balls, mountains, the sea, cats and many women have great interfaces. Pianos - not so much. – Vitaly Mijiritsky Mar 31 '11 at 7:53

@Glen - as has been stated many times before - this is not a discussion site. It is a Q&A site. – Charles Boyung Apr 20 '11 at 14:01

It's hard to name these things because, as with all well-designed items, we don't think of them as well-designed, because they so naturally fit into our lives. Think about toothbrushes, doorknobs, drawers, light switches (though they could be better, yes). They all have user interfaces (because they can be interacted with by a user) and they all are nearly perfect.

Also, look at musical instruments. They evolved for hundreds of years and have achieved a high level of perfection.

I'd say either:

  • An ATM machine - although they are a bit more complex nowadays, but back when they only offered withdrawal of cash (not phone topups, deposits etc that they offer now).

  • Pedestrian traffic crossing signals - single button interface with clear feedback to the user as to what to do.

It could be argued that neither of these require training to use and while not 100% instinctive are pretty darn close.

What's an automated teller machine machine? A machine that creates ATM's? – Charles Boyung Mar 31 '11 at 13:28
Ok, I guess I deserved that. ;-) – JonW Mar 31 '11 at 13:44

I like wall-mounted manual PET bottle compactors. The sound of plastic crounching with just a minimal force application while knowing that you did something good for the environment is really satisfactory.
