Promoting a separation of concerns via closely-related interaction and presentation models

A common goal of HCI design processes is to provide an organized set of procedures and representations to develop high-quality interactive systems. However, we find large gaps between representations in existing approaches, and some representations do not have a clear scope or focus. This paper proposes to use a set of closely-related notations to address different sets of design issues in successive stages of design, aiming to achieve a clear separation of concerns. In particular, it focuses on the transition from an interaction model to an abstract presentation model.
