Functionality specification for adaptive user interfaces

Abstract

The goals of human-computer interaction are to provide functional, usable, safe and well designed computer system interfaces, thus achieving almost transparency and enabling end users to fully concentrate on work. Over the years the need has been recognized for the development of adaptive user interfaces in several application areas. Our research is concentrated on adaptive user interfaces for intelligent tutoring systems, which allow human teacher emulation in the process of learning and teaching. In the paper we consider the functionality specification of an intelligent tutoring system user interface expressed by means of user action notation, and discuss the way it has to change the provided functionality and its presentation on the basis of users' individual characteristics, in order to accommodate differing user requirements.
