An Interface Model for Evaluation Task-Interface Congruity

Abstract

To help people learn and understand the use of increasingly complex devices, the interfaces should be designed to be compatible with the users task knowledge. This paper proposes a new diagrammatic interface model that enables intuitive analysis and representation of users interface knowledge in the domain of softwares and electronic devices. The model explicitly defines the abstraction of procedures in the users understanding of interface for the objective examination of correspondence between the task knowledge and the interface.
