Display of Information for Time-Critical Decision Making

We describe methods for managing the complexity of information displayed to people responsible for making high-stakes, timecritical decisions. The techniques provide tools for real-time control of the con guration and quantity of information displayed to a user, and a methodology for designing exible human-computer interfaces for monitoring applications. After de ning a prototypical set of display decision problems, we introduce the expected value of revealed information (EVRI) and the related measure of expected value of displayed information (EVDI). We describe how these measures can be used to enhance computer displays used for monitoring complex systems. We motivate the presentation by discussing our efforts to employ decision-theoretic control of displays for a time-critical monitoring application at the NASA Mission Control Center in Houston.
