Of men and machines: More than 10 years of experience with electures at universities

Over the last decade the Computer Science Department of the University of Freiburg has gained a lot of experience with the production and use of electures poduced from live recordings. We review the origin of the tools used for presentation recording and emphasise the consquences of the object-based approach in contrast to screen grabbing. By extensive user studies and logfile analyses we revealed the preferences of users with respect to different formats of electures, navigational patterns, and ways of utilization. Though there are currently a number of different options for recording live presentations available, there are still a number of core features not solved satisfactorially. Therefore, we finally describe new developments possibly leadung to better systems.

From 1976 until 1987 he was Professor at the Institut AIFB in Karlsruhe. In 1987 he became the first professor for Computer Scince at the University of Freiburg. There, he was significantly involved in the establishment of a new Technical Faculty. He was visiting professor at the universities of Waterloo, Canada, ETH Zürich, Switzerland, Harris Guestprofessor at Dartmouth College, New Hampshire, USA, and visiting professor at the University of Western Australia, Perth.

He served as Secretary of the European Association for Theoretical Computer Science, as elected referee for the German Science Foundation (DFG), and coordinated special research research programmes in Algorithms and Data Structures. He served as member of the Scientific Advisory Committee of the State of Lower Saxony. He is member of the steering committee of the Swiss Virtual Campus, member of the Advisory Board of the L3S, Hannover, and member of the Evaluation Panels of the Universities Tampere and Oulu, Finland. Since 2006 he is head of the Technical Committe of the Accreditation Agency ASIIN specialised in accrediting degree programs in Engineering, Informatics, the Natural Sciences, and Mathematics. Since October 2006 he is GI-Fellow.

He authored four and edited seven books and published more than 150 scientific papers. His researchn interests include Algorithms and Data Structures, Computational Geometry, Multimedia Systems, and eLearning.
