Abstract

Lecture recording provides learning material for local and distance education. The TeleTeachingTool uses the very 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 are obtained by automated post‐production. This article presents how automated analysis generates indices for slide‐based navigation on the fly and how to achieve live interlinkage of annotations with slides so that annotations disappear when a slide is changed and are made visible again when returning to that slide later during presentation, although screen recorders generally do not provide an association of annotations with slides.
