Time-based content marks for fine-grained navigation in educational content

One of today’s major problems in the field of e-learning is that the creation of high-quality content is still rather time consuming and expensive. In the past, many efforts have been made to produce educational content on the fly, but the results were mainly static blocks of lecture recording lacking sophisticated navigation facilities. Facing this challenge the authors developed the concept of hyperpresentations. During the live presentation content- and time-based metadata is captured and stored in a lightweight and player-independent format. With this metadata powerful navigation facilities like real time navigation and full text search in audio or video data can be generated automatically.
