The field of Human-Computer Interaction (HCI), whose goal is to make computers support human activity in much more satisfying ways than they currently do, has three main uses for cognitive modeling. A cognitive model can substitute for a human user to predict how users will perform on a system before it is implemented or even prototyped. A system can generate a cognitive model of the user currently interacting with the system in order to modify the interaction to better serve that user. Finally, cognitive models can substitute directly for people so groups of individuals can be simulated in situations that require many participants, e.g., for training or entertainment. This paper presents some instances of such models and the implications for GI design.
