What people expect from an interactive kiosk
A kiosk is a fixed point where someone comes to get information without waiting for a member of staff. A self-service kiosk in a lobby, a column at a shop entrance, a tablet on a counter. The visitor has a question, the kiosk answers it.
So what matters is not the object but the quality of the answer. A kiosk that shows a menu of six buttons only answers the six questions someone thought of. People ask the seventh.
