Star Cruiser is a complex laboratory task that was designed to study decision making processes. It is intended to provide a rich perceptual environment in which to study the perceptual decision heuristics utilized by operators in similar tasks (Shively & Kirlik, 1991, Kirlik, Markert & Shively, 1990). In addition, a great deal of flexibility is offered by its script-style control. Researchers interested in such areas as workload, situational awareness, and skill development may also find it useful. It is presently being utilized in laboratories at NASA-Ames and Georgia Tech, where it was jointly developed, but the software is now available for distribution to other interested laboratories.
