Abstract

Lecture recording provides learning material for local and distance education. Screen recording offers a flexible technique for lecture recording as it allows to capture virtually any material displayed during a presentation. Unfortunately, the navigational features and search abilities are rather limited, because grabbing and storing pixel data deprives the structure and content of the source documents. This paper presents how analyses of such pixel based recordings deliver useful navigational indices and provide full-text search automatically. In order to establish these research results, we have (partly) implemented the ideas within our own screen recording environment called TeleTeachingTool.
