Personalization-based optimization of Web interfaces for mobile devices

Developing personalized applications for the ubiquitous Web assumes to provide different user interfaces addressing heterogeneous capabilities of device classes. Major problems are the lack of sufficient presentation space and the diversity of interaction techniques, both requiring adaptive intelligent user interfaces. To meet this challenge this paper introduces an approach for the personalization-based optimization of Web interfaces for mobile devices. On the basis of a user model different adaptation issues are discussed. Firstly, static adaptation mechanisms affecting the structure of Web documents as well as layout managers enabling a device independent definition of Web presentations for heterogeneous devices are introduced. Then an interactive mechanism for dynamically predicting user preferences for hiding unnecessary information through content adaptation is presented. As a proof of concept an architecture realized by a pipeline-based document generator was developed for static/dynamic adaptation, which is partly explained in this paper.
