Conceptual Modelling for Interaction Design

A usable interactive system provides its users with presentation and manipulation of useful concepts for solving their problems at hand without becoming bogged down in accidental features of user interface. It implicates that interaction design is directed by the acquisition and representation of knowledge about the context of use in a way that can be traced back to the users’ problem-solving activity. In this paper we focus on conceptualization of that activity. The conceptualization is characterized by a set of ontological terms that capture a continuum between user tasks and problem domain in a declarative way, and by a framework of conceptual models that describe a system on a very abstract level without being limited to particular design models.
