DragonFly is an application designed for reviewing lecture recordings of mind map-structured presentations. Instead of using a timeline slider, the lecture recording is controlled by selecting elements located at different positions on the map. Hence, video time is controlled by navigating in space. A controlled experiment revealed that DragonFly reviewers performed 1.5 times faster in finding a specific scene of a lecture recording compared to reviewers that worked with QuickTime Player and a mind map printout.
