In this work, the authors present a fully automated recorded lecture summarization tool and an innovative mobile iPad visualization tool. Summarization works for blackboard-based lectures by robustly extracting blackboard edits with great accuracy and high performance. Analysis output is then presented with overview and visual timelines along the original video to allow discovering lecture passages based on time. A second option allows students navigating contents in space by allowing revisiting blackboard elements directly by touching regions in the video. Proposed summarization, temporal and spatial navigation along with interactive visual annotations bring to recorded lectures the benefits that other digital learning material has long enjoyed and entice a younger generation of learners.
