Interface Engineering and Design : Adaptibility Problems

The paper describes some investigation’s problems intended to construct user model via psychological assessment for further interface adaptation. The proposed concept of user model comprises formal representation of demographic, professional, physiological and psychological data about the user with stress put on psychological features. Essential users physiological, communicative and cognitive peculiarities are in the center of view in the research theoretical part. The presented research develops flexible usercentered approach as a unity of two main investigation directions – user modeling and adaptive interface’s design. The adaptation engineering procedure is investigated via special interface modeling approach. The targeted implementation is distance learning process. Special software tool InterTrivium for interactive questionnaire presentation is described
