About Me I've studied computer science at the Saarland University from 1990 to 2000. My Diploma thesis about automated layout of Yellow Pages was finished in 1996, and followed by my Ph.D. thesis about adaptive layout of Web pages, which I finished in 2000. In 1995 I joined the German Research Center for Artificial Intelligence (DFKI GmbH) in Saarbrücken, where I'm working today as Senior Researcher. My general research interests comprise adaptive user interfaces, Semantic Web, and Ubiquitous Computing. Within these areas, I devoted so far special attention to the building and the exploitation digital memories, the related issue user modeling, and methods for adapting layout and style.

Object Memory Modeling. W3C Incubator Group Report, Worldwide Web Consortium, 2011.

Abstract
This report summarizes the findings of the Object Memory Modeling Incubator Group. An XML-based object memory format is introduced, which allows for modeling of events or other information about individual physical artifacts, and which is designed to support data storage of those logs on so-called "smart labels" attached to the physical artifact. The group makes several recommendations concerning the future evolution of the object memory format at the W3C; these address connections to provenance modeling, the embedding of object memories in web pages, and potential benefits of an object memory API.

Visualizing the Impact of Content-Based Similarity and Spatial Distance on Book Recommendations. In Katherine Blashki (Ed.), Proceedings of the IADIS International Conference on Interfaces and Human Computer Interaction. IADIS International Conference on Interfaces and Human Computer Interaction (IHCI-11), located at IADIS Multi Conference on Computer Science and Information Systems, July 24-26, Rome, Italy, pp. 345-350, ISBN 978-972-8939-52-6, IADIS Press, 2011.

Abstract
Starting from the assumption that an integration of digital services might help brick-and-mortar bookstores to compete with online sellers, we propose a recommender system which takes into account not only content-based similarity of books, but also local availability and spatial distance. This article addresses work in progress; its focus is on a particular question tightly connected to the user interface design of such a system: how to communicate results from these different information sources to a customer in a transparent way. We contribute to this topic with several design proposals and a discussion of feedback collected in a user study.

Digital Product Memories and Product Life Cycle. In Proceedings 2011 of the 7th International Conference on Intelligent Environments (IE-11), pp. 374-377. IEEE Computer Society, ISBN: 978-0-7695-4452-6, 2011.

Abstract
In this paper we describe a demonstration as it was presented to a wide audience at the Hannover Messe Industrie 2010. The demonstration shows a future production scenario spanning several linked stages ranging from individual ordering over assembly, filling, and shipping to individual support and comprises in total 5 demonstrators from 5 partners. Visitors could order and configure their own product and how to ship. Products which were produced in this scenario were equipped with a so-called digital product memory. Via this digital product memory data is collected along the product life cycle from individual ordering, assembling, filling to shipping. At home the user could browse the digital product memory and benefit from individual services which build up on the digital product memory.
