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, time-critical decisions. The
techniques provide tools for real-time control of the configuration and
quantity of information displayed to a user, and a methodology for designing
flexible human-computer interfaces for monitoring applications. After defining
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.
