Lift panel displaying buttons with text in German next to them . Starting from top to bottom:
3 = Ebene 2 (Bensheimer, Berg, Mahler, Schönberg, Seminarraum 9+10), WC, 2 = Ebene 1 (Empore Mozartsaal, Herberger Lounge), 1 = Ebene 0 (Foyer Ost, Mozartsaal, Haupteingang), Open door, close door, alarm = Notruf
This elevator technically works, but it’s labelling does not match a user’s mental model, forcing them to think harder than necessary.
To get to Level 2, you have to press 3. For level 1, you press 2.
Great #UX design isn’t just functional. It’s #intuitive, #clear and #HumanCentred.
