Moreover, EID argues that this information should be represented through graphical visualizations. However, EID has assumed that the raw data needed to derive the higher-order information could be measured and that the graphics would not be susceptible to instrumentation failures. In fact, recent EID research indicates that current instrumentation technology and specification policies may adversely impact the implementation of such visual displays. The current research empirically evaluates the impact of such limitations on the robustness and effectiveness of an EID-based interface for a pasteurization microworld simulation representative of industrial process control systems. The results of this research were the following. First, the Abstraction Hierarchy was uniquely extended to indicate instrumentation requirements to support human-machine interfaces. Second, an original EID interface was designed and the iterative process of design was cataloged and characterized---a process often ignored in EID literature. Third, the empirical evaluation suggested that steady-state control performance of operators was not negatively impacted by sensor failures when using an EID interface or the conventional mimic display. Furthermore, displaying higher-order information appeared to support general diagnostic performance when dedicated sensors were used to derive this information. But as hypothesized, this diagnostic performance was compromised when higher-order information was derived from distally measured data. When compared to the mimic display that digitally displayed the measured data, detection and general diagnostic reasoning was supported by an EID interface with distally derived higher-order information even though diagnostic accuracy suffered. Finally, empirical investigation also indicated that there was not a superiority between the EID interface and the conventional interface in terms of average performance for diagnosis and control.
