Using cognitive simulation to develop user interface design principles

The authors develop theory-based user interface design principles. The goal is independent detailed simulations of user command production in the Unix operating system and Framer, a user-interface design tool. The simulations are based on the construction-integration theory and build on the action planning model developed by S.M. Mannes and W. Kintsch (1988). Use of the model provides insight into why certain types of command productions pose problems for Unix users and shows promise for explaining problems for user of Framer
