This paper evaluated user interaction with the graphical user interface of WRESTORE, an environmental decision support system (EDSS) for watershed planning that utilizes user ratings of design alternatives to guide optimization. The following usability metrics were collected for stakeholders as well as surrogates (who are often used for DSS development due to time or cost constraints): task times across sequential sessions, percentage of time spent and of mouse clicking in different areas of interest, and trends in self-reported user confidence levels. Task times conformed to theoretical models of learning curves. Stakeholders, however, spent 15% more time and made 14% more mouse clicks in information gathering areas than surrogates. Confidence levels increased over time in 67% of stakeholders, but only in 29% of surrogates. Relationships between time spent or mouse clicking events and confidence level trends indicated that confidence ratings increased over time for users who conducted more information gathering. This study highlights the importance of increasing user interactions within information gathering areas of an interface to improve user-guided search, and suggests that developers should exercise caution when using surrogates as proxies for stakeholders. It also demonstrates a quantitative way to evaluate EDSS that could assist others developing similar tools.

By addition of analytical equipment, scanning transmission accessories and data processing equipment the basic transmission electron microscope (TEM) has evolved into a comprehensive information gathering system. This extension has led to increased complexity of the instrument as compared with the straightforward imaging microscope, since in general new information capacity has required the addition of new control hardware. The increased operational complexity is reflected in a proliferation of knobs and buttons.In the conventional electron microscope design the operating panel of the instrument has distinct control elements to alter optical conditions of the microscope column in different modes. As a consequence a multiplicity of control functions has been inevitable. Examples of this are the three pairs of focus and magnification controls needed for TEM imaging, diffraction patterns, and STEM images.
