摘要：We propose a specialized mobile visualization tool for recorded lectures that until now have only achieved marginal usage when viewed with traditional tools. Our solution enriches videos with advanced content summarizations created manually in a visual way, or extracted automatically using specially developed desktop blackboard and screencast lecture analysis tools. In this work, we empirically validate our visualization and summarization tools through a student survey. The results and overwhelming positive feedback confirm our research hypothesis about recorded lecture drawbacks while clearly showing that in order to dramatically increase students' interest a specially tailored playback environment with flexible contents' navigation is crucial.
