Abstract

The importance of the user interface increases particularly in safety-critical or mission-critical systems where the user has time limitations within which to make correct, accurate, and timely decisions. User interfaces for these type of systems should be well-designed, easy to understand and easy to use in order to be accepted by expert users and to support the users’ decision making under pressure. Otherwise emergencies such as mishaps or accidents may occur and consequences of accidents may include loss of human life, large financial losses, and environmental damage. In this research, we study user interface complexity and the impacts of this complexity on users’ acceptance of that system as well as other impacts on user performance in safety-critical environments. We use the measurements and experiments with the Navigation and Piloting Expert System (NPES) and its operators to quantify our research and report details of metrics, measurements, experiment, findings, and conclusions.
