Abstract

Computers can assist decision makers in a variety of different ways. They can, for instance, support users with improved access to information, with more informative displays of this information, or with more effective forms of communication. They can also use algorithms to actively monitor situations and to generate inferences in order to assist with tasks such as planning, diagnosis and process control. This chapter focuses on interaction design issues associated with this latter role, in which the software uses numerical computations and/or symbolic reasoning to serve as an active decision-support system (DSS) . An underlying assumption in design of human-centered systems is that the characteristics of the user population, the tasks they perform, and the context and environment in which they perform them are all inherently intertwined. DSS designers need to understand all three in order to understand what support a DSS should provide to help users to be more effective in a specific task and context. This chapter aims to provide DSS designers with approaches for understanding of all three, and their integration.
