Formal Modeling and Reconfiguration of User Interfaces for Reduction of Errors in Failure Handling of Complex Systems

摘要

Controlling and observing complex systems is central to the study of human-machine interaction. In our understanding, there is much to be gained from integrating formal modeling and analysis, including the reconfiguration of user interfaces, with the development of user interfaces with high usability. To this end, we introduce a new approach to modeling and reconfiguration of user interfaces jointly with a newly developed set of tools for interactive and visual creation and automatic transformation of user interfaces' interaction logic to a formal language based on Petri nets. Reconfiguration will be embedded into a process for adapting user interfaces to the user's cognitive representation of the controlled system. This process involves practicing the use of a given user interface, adapting it to the user's needs through reconfiguration, and applying the resulting adaptations to the formally defined interaction logic. An evaluation study confirms that this process reduces errors in interaction.
