| Abstract: | The conceptual design of user interfaces focuses on arriving at a
specification of the structure of the dialog, independent of any
particular implementation approach. There is common agreement as to the
importance of this activity to both IS professionals and end-users, but
few -- if any -- modeling methods were developed to specifically support
the process of conceptual design, and the usefulness of such methods has
not been adequately addressed. This paper introduces the Dialog Charts
(DCs), and documents a preliminary examination of their perceived
usefulness by designers of user/system interaction who actually used
them. The DCs yield high level dialog schemas that are abstract enough
to support the conceptual design of dialog control structures. In a
uniform diagramming framework they combine the concept of dialog
independence, distinguish between the dialog parties, provide for
hierarchical decomposition and enforce a structured control flow. The
usefulness of the DCs has been studied empirically in a qualitative
inquiry. Recalled experiences of designers were captured and analyzed to
ascertain the concept of usability, as well as assess the usability of
the DCs. Usability has emerged from this study as a set of 38 concerns
that operationalizes the broader aspects of purpose of use, design
stage, impact on product structure, impact on design process, and
attitudinal patterns. In general, the Dialog Charts were found by these
dialog designers to be a useful, exhibiting the essential attributes of
tools for conceptual modeling. |
