Navigational Indices and Content Interlinkage on the Fly

Lecture recording provides learning material for local and distance education. The TeleTeachingTool uses the most flexible screen recording technique to capture virtually any material displayed during a presentation. With its built-in annotation system teachers can add freehand notes and emphasize important parts. Unlike other screen recorders, our implementation offers slide-based navigation, full text search and annotated scripts, which is obtained by automated post-production. This paper presents how to achieve live access to any slide with corresponding annotations created earlier during the presentation, although annotations are not associated with slides. For this the post-processing algorithms must be adapted to work on the fly while the presentation is still in progress and an interlinkage between slides and annotations must be achieved.
