We describe a collaborative research and development effort
between the Palo Alto Laboratory of the Rockwell Science Center,
Rockwell Space Operations Company, and the Propulsion Systems
Section of NASA JSC to design computational tools that can manage
the complexity of information displayed to human operators in
high-stakes, time-critical decision contexts. We shall review an
application from NASA Mission Control and describe how we
integrated a probabilistic diagnostic model and a time-dependent
utility model, with techniques for managing the complexity of
computer displays. Then, we shall describe the behavior of VPROP,
a system constructed to demonstrate promising display-management
techniques. Finally, we shall describe our current research
directions on the Vista 2 follow-on project. (Author (revised))
