Identify relevant parts in lecture recordings University of Pittsburgh VirtPresenter provides three versions of footprints to users. The first version displays users own footprints for orientation over a longer learning period. The second version visualizes other learners footprints in form of different color shading corresponding to frequency of visits per snippet. The third is used to compare personal and foreign footprints

Edit the recordings online & extract parts Students can produce a „Best off“ of a lecture series Different lectures can be mixed Compact knowledge Short and compact content for podcasts / mobile devices (wikis, blogs...) Increase user acceptance (students as well as lecturer) Wrong parts in a recording can be removed from a lecturer 18

Cutting out relevant parts University of Pittsburgh Whenever a user decides to bookmark parts of recordings for later use she can cut out this passage online using two small markers in the interfaceand add it to the bookmark section.This selection can also be exported via hyperlink to external systems, like a course wiki, a group blog or just to the regular bookmark space of a webbrowser.
