ABSTRACT
As emphasized throughout this book, the domains within which human agents are asked to work are complicated ones. Today the computer is a window into large, complex work spaces and databases. As a direct consequence, the interfaces that provide decision support for these agents will also need to be complicated (i.e., will need to address the requisite variety). All of the information that is needed for control will rarely be contained on one screen and the human agent will often be required to navigate through a set of screens.
