Paper abstract bibtex

Adaptive interfaces have received a lot of criticism as adaptation and automatic assistance contradict with the principles of direct-manipulation interfaces. In addition to this, their success highly depends on the ability of user models to capture the goals and needs of the users. Since the construction of user models is often based on poor evidence, even the most advanced learning algorithms may fail to accurately predict the user goals. Previous research has not put much effort on investigating the usability problems that adaptive systems engage and developing interaction techniques that could resolve these problems. This paper presents an interaction model for Adaptive Hypermedia which merges adaptive support and direct manipulation. This approach is build upon a new content adaptation technique which derives from fisheye views. This adaptation technique supports incremental and continuous adjustments of the adaptive views of hypermedia documents and balances between focus and context. By combining this technique with visual representations and controllers of user models, we formed a twofold interaction model which enables users to quickly move between adaptation and direct control.
