Abstract
Conference Title: 2017 IEEE Frontiers in Education Conference (FIE) Conference Start Date: 2017, Oct. 18 Conference End Date: 2017, Oct. 21 Conference Location: Indianapolis, IN, USA We present a new tool to help students make use of video recordings of traditional chalkboard and whiteboard lectures. Our tool provides a compact summary of a chalkboard lecture in the form of a set of slides, and an interactive environment for electronic note-taking in real time while watching a lecture in class or during review. Key to the processing of a chalkboard video by our system is the removal of the lecturer from the video (now no longer present to occlude the board) and segmentation of the resulting video to produce a set of slides comprising a compact presentation of the content written on the board during the lecture. Our method enhances learning in a number of ways. Students can focus on taking notes to supplement the material, rather than rote transcription. In addition, notes are aligned temporally with the lecture video and thus provide a useful way for students to index into the important parts of the video. Our system can be easily integrated into courses with a recorded lecture video component to help students organize their notes and quickly navigate the lectures from a given course for particular topics.
