Three studies illustrated the iterative interaction of laboratory research in the system design process. They focused on operator performance in an imaging infrared ship target acquisition system. Ship type, display contrast, ship orientation, and video bandwidth had significant effects on operator performance, whereas video frame rate yielded a flat function. These results were discussed in the context of a distinction between informational and image quality effects on target acquisition performance. A basis in part-task simulation for estimating times to perform component tasks was also established.
