Cognitive Models

Cognitive models are ways of describing or predicting user performance through a generalized representation of the way a type of user would interact with a system. The model allows a designer to consider the implications of design decisions (and frame possible approaches to design) prior to getting direct user feedback on a design. The models should be informed by previous analysis of users, to have some confidence in the model's ability to represent the way a user might think or interact.

Descriptions of models that will be available include commonly known models like Fitts' Law and Hick's law (Hick-Hyman law), gestalt principles, and the family of GOMS models.
