EduCase : an automated lecture video recording, post-processing, and viewing system that utilizes multimodal inputs to provide a dynamic student experience

[摘要] This thesis describes the design, implementation, and evaluation of EduCase: an inexpensive automated lecture video recording, post-processing, and viewing system. The EduCase recording system consists of three devices, one per lecture hall board. Each recording device records color, depth, skeletal, and audio inputs. The Post-Processor automatically processes the recordings to produce an output file usable by the Viewer, which provides a more dynamic student experience than traditional video playback systems. In particular, it allows students to flip back to view a previous board while the lecture continues to play in the background. It also allows students to toggle the professor;;s visibility in and out to see the board they might be blocking. The system was successfully evaluated in blackboard-heavy lectures at MIT and Harvard. We hope that EduCase will be the quickest, most inexpensive, and student-friendly lecture capture system, and contribute to our overarching goal of education for all.
