Information system user interface complexity

Abstract

This paper examines problems and solutions related to the integration of the HCI perspective in software engineering and production. The goal is to bridge the gap between software engineers and HCI professionals by improving mutual understanding of their respective fields of interest. An information system is a complex system that can be modelled by means of the multilevel theory. The user interface design is a design problem without a single proper solution. There is no standard user interface look and feel, so that a multilevel user interface model is proposed. The user interface design is approached through hierarchical levels making it possible to choose between multiple developments methodologies. Case study: A highway automatic toll collection system user interface design proves that the multilevel approach can bridge the gap between developers and designers making team members use their respective strong points. © 2010 Springer-Verlag.
