Consider the following excerpts: While the use of advanced technology is generally considered to enhance system performance, computer-based operator interfaces also have the potential to negatively affect human performance, spawn new types of human error, and rP`lilrP Hilton rPli~hilit~l , ~ , ^~ ..

Getting lost describes the phenomenon in which a user, or operator, becomes lost in a wide and deep forest of display pages (Woods, 1984~. Empirical research shows that some operators use information suboptimally in order to reduce the number of transitions among display pages

The advent of supervisory control raises many concerns about human performance. Changing the operator's role to that of a predominantly passive monitor carrying out occasional interventions is likely to tax human capabilities in an area where they are already quite weak (Wickens, 1984~.

NUREG-0711 acknowledges both the possibility of all of these roles for human operators in advanced control rooms and the lack of any consensus on if or how to design human interfaces to effectively support them. Reviewing Systems for Effective Human-System Interaction Human-system interaction reviews should proceed carefully and in a series of steps.

An approach based on a combination of judicious use of guidelines, a principled design process, realistic prototypes, and performance-based evaluation is likely to produce a design product that enhances operator effectiveness and guards against common design deficiencies in computer-based interfaces.
