User Interface Issues in Real Time Decision Support Systems

摘要

We have been working at the NCCOSC RDT and E Division (NRaD) to develop newmethods of assisting Navy decision makers in real time command and control decision-making situations. Our work has focused directly on the incorporation of new kinds of knowledge based computer tools into shipboard decision support systems. As part of that work, we have had the opportunity to examine various approaches to influencing human decision makers through interface manipulations. The general conclusion we have reached is that interfaces used by expert decision makers in real time situations should make only limited use of techniques such as direct manipulation that require users to interact with the system. It follows that efforts to provide a critiquing mechanism should emphasize critics that operate automatically without waiting for the user to request assistance. However, we are also looking for an interface that does not automatically change displays in ways that users may find intrusive, or otherwise objectionable. To address both having automatic criticism and non-intrusive display changes, we are looking for ways to provide critiquing that is transparent to the user.
