A User Decision Model for the Evaluation of the Human Computer Interface

This paper discusses a dynamic model of the user's interaction with the user computer interface. It addresses how the user's decision processes interact with different levels of complexity in the user interface. Cellular automata are used to model the interaction of user decision schema and user computer interfaces. The user's decision schema determine the navigation through the interface. Users with idiosyncratic decision schema can effectively navigate only simple interfaces while users with data analytic decision schema can navigate both simple and complex interfaces.
