Pattern-based UI design: Adding rigor with user and context variables

Abstract

In current practice, user interface development is often based on a vague and undocumented design process, relying solely on the designer's experience. This paper defines a pattern-based design process, which adds rigor to user interface design. The process is based on the notion of user variables to capture user requirements in a formal manner - based on discrete values that are amenable for tool support and automated analysis. Other context of use information is captured as context variables. Using these values as input, design patterns are selected to leverage best design practices directly into user interface development. Pattern-Oriented Design is then employed to derive a conceptual design, or early prototype, of the user interface. A case study with a Bioinformatics information site exemplifies the feasibility and applicability of this process. © Springer-Verlag Berlin Heidelberg 2007.
