Abstract
Existing methodologies for design focus upon capturing of design
rationales, methods for domain analysis, or evaluation methods. There is
little or no support for making design decisions; rather, design is
regarded as an artistic process that only can be improved through
experience. This paper presents a structural approach to the iterative
process of designing effective and efficient human-computer interfaces.
Four different phases of the design process are described: Identification
of the information contents, specification of the layout, dialogue
structure, and the behaviour of the user interface. Design decisions
made in these phases are based on a set of heuristics. The prerequisites
for the user interface design process is an analysis of the domain, the
users, and the technical environment. Based on this, a suitable metaphor
can be chosen. A "workspace metaphor" supporting administrative work in a
broad sense performed by skilled professionals is introduced. By creating
interface elements and work-spaces in an iterative design process, a first
prototype can be defined. Some design examples are shown.
