| Abstract: | The conceptual design of user interfaces focuses on the specification of
the structure of the dialog, independent of any particular
implementation approach. While there is common agreement with respect to
the importance of this activity, adequate methods and tools to support
it are generally unavailable. The Dialog Charts (DCs) presented in this
paper address this problem -- they support the conceptual design of
dialog control structures. The DCs combine visual modeling (i.e.,
diagraming) with widely accepted design principles and an explicit model
of dialog structures. As no clear evaluation criteria exist in this
evolving area of dialog design, the preliminary assessment of the DCs
takes the form of contrasting them with representative alternative
design tools based on Augmented Transition Networks or Backus-Naur Form
grammars. The DCs overcome some of the problems that seem to limit the
usefulness of comparable approaches. An empirical investigation of the
usable power of the DCs is currently underway at New York University,
and a summary of this research activity concludes the paper. |
