Applying a Cognitive Engineering Approach to Interface Design of Energy Management Systems

This article presents a case study of the user interface design of a grid (energy) management system. The theoretical backdrop of the case study is cognitive engineering, with its focus on supporting three levels of cognitive control, namely skill-, rules-, and knowledge-based control, respectively. In this design case study, the interface of the grid management system is divided into three hierarchical levels, each corresponding to a type of cognitive control. Details of the prototype system (the Compact System State Display) are introduced, as a reference to readers familiar with the particular challenges of designing energy management systems. The article also discusses the basic assumptions regarding human cognition and behaviour that engineers and designers might utilize in the design process, including the pros and cons of these assumptions.
