Cognitive Ergonomic Evaluation Metrics and Methodology for Interactive Information System

In the face of complex information interactive system, it is essential to evaluate products achieve system performance within users cognitive capacity. Most of the research about ergonomic evaluation mainly focus on the macro ergonomic method, which not focus on concrete design problem at the micro level. This paper focuses on how to identify and predict cognitive ergonomic problems based user action and cognitive model and establishes the mapping relationship between cognitive ergonomic problems and real-time continuous measured data in order to let the evaluation results play a direct role in the design. The methodology was applied to evaluate the ergonomic quality of IETM used by astronauts in the space station, which including make flight plans, do experiments, in-orbit maintenance, and so on. A series of standardized evaluation procedures were designed to explore the possibility of remote ergonomic measurement for long-term orbiting operation.
