Domain-specific design of user interfaces

The use of graphical user interfaces in a computerised work environment is often considered to substantially improve the work situation. The outcome can, however, often be the opposite. Inappropriate use of windowing techniques, scrolling and colours can result in tedious and confusing interaction with the computer. Today's standards and style guides define basic design principles but are insufficient for design of interfaces to end-user applications. Here detailed domain knowledge is indeed essential. A domain-specific style guide (DSSG) is an extension of today's standard with domain-specific primitives, interface elements, and forms, together with domainspecific guidelines. Careful dedicated analysis of information utilisation in a domain is the development basis for a DSSG. The development is performed with an objectoriented approach to facilitate the reuse of interface components and to support consistency and structure. Using a DSSG the development of applications can be performed with a simplified information analysis. Therefore a more effective design process is possible, one in which end users can participate in the design using their own familiar domain-related terminology. Time and costs for the development process can be drastically reduced if domain-specific style guides, design guidelines, and development tools are used.
