Abstract

Hard-key user interfaces are ones where the interface does not change during an interaction. Soft-key interfaces, on the other hand, change the meaning of inputs such as buttons as the interaction progresses. We demonstrate how interactive systems with either kinds of interface can be verified in HOL by combining a generic user model and a device specification incorporating a specification of the interface. In particular we show how design problems which result in users systematically making errors can be detected. We have extended the user model from previous versions to detect new errors related to soft-key interfaces.
