Abstract
The next generation cruise missile, the Tactical Tomahawk, improves upon current versions by its ability to be retargeted in flight against targets of opportunity. We have developed a testbed for evaluating alternative display concepts and decision support features on the effect of an operator's ability to maintain situation awareness and make appropriate time-critical decisions. This user interface design was based on an analysis of critical operator tasks, and the concepts of representation aiding and limited workspace management. The testbed was developed with Macromedia Director, allowing it to be run cross-platform (Windows, Macintosh, and the Internet). One set of studies has been conducted so far with this system, to compare alternative display features on the effect of subject situation awareness and decision making.
