The role of models in handling complexity, flexibility and reliability of human-computer interfaces

General and specific aspects of modeling human-computer interfaces (HCIs) are investigated. Possibilities and methods of using structural architectures in interface construction together with the according hierarchy and modularity in HCI modeling are described. Efficiency and reliability in human-computer interaction are found to be dependent on the complexity and flexibility of the interfaces. The concept of universal, application-oriented, and application-specific HCI components is introduced. Methods of modeling HCIs and HCI modules are outlined, emphasizing the role of experiments made by fast computerized prototyping.<
