Abstract

Advocates focus on the joint human computer task performance in system design. Human involvement can be improved by designing system functions which complement human knowledge and capacities. Based on general needs for cognitive support, proposes an aiding function which takes the initiative to present context specific, procedural task knowledge. Design of such aiding comprises: design of software and design of huhman computer system. Modern model based software engineering methods provide strong support for the design of software systems, but little support for modelling the human computer interaction. Current model based methods are extended to address human computer interaction issues. The resulting method comprises the design of easy to use and learn interfaces providing, if needed, aiding. In a case study, the method is applied to design a conventional plain interface and an aiding interface for the statistical program HOMALS. In an experiment, users with minor HOMALS expertise prove to perform their tasks better and to learn more with the aiding interface
