Research on when and how to use three-dimensional (3D) perspective views on flat screens for operational tasks such as air traffic control is complex. We propose a functional distinction between tasks: those that require shape understanding versus those that require precise judgments of relative position. The distortions inherent in 3D displays hamper(More)
Tactical displays can quickly become cluttered with large numbers of symbols that can compromise effective monitoring. Here, we studied how heuristic automation can aid users by intelligently "decluttering" the display. In a realistic simulated naval air defense task, 27 experienced U.S. Navy users monitored a cluttered airspace and executed defensive(More)
51 A ir-traffic controllers, military personnel, and others need displays that rapidly convey the location and other attributes of objects (such as aircraft) in 3D space. The ongoing revolution in the availability of inexpensive and fast 3D rendering technologies is allowing display designers to develop 3D prototype displays for this purpose, such as Figure(More)
How are knowledge-intensive, text-comprehension processes computed? Specifically , how are (1) explicit propositions remembered carrectly, (2) pronouns resolved, (3) caherence and prediction inferences ?rawn, (4) ongoing interpretations revised as more information becomes available, and (5) information learned in specific contexts generalized to navel(More)
The Defense Advance Research Projects Agency Augmented Cognition program is developing innovative technologies that will transform human–computer interactions by making information systems adapt to the changing capabilities and limitations of the user. The first phase of the Augmented Cognition program was to empirically assess the ability of various(More)
