Audio-Visual Data Skimming for E-Learning Applications

Using multimedia documents for learning puts specific demands on the user interface. Users want to be able to quickly skim audio-visual data in order to locate relevant information, skip parts of minor interest, reset replay to interesting positions, etc. In this paper we propose a new interface design which extends common media player interfaces by offering a new way for interactive, synchronised audiovisual data browsing. This approach allows users to skim multimedia documents at arbitrary speed and granularity levels with immediate visual and acoustic feedback.
