Two Automated Mechanisms to Create eLectures and to Videotape Regular Lectures
Nael Hirzallah · 2012
Many institutes are offering lectures that students may watch online. These lectures vary in type from true multimedia sophisticated documents to eLectures to videotaped regular lectures that may include auto generated closed caption. This paper studies some formats that can be easily composed by instructors. Whether adopting the eLectures format or videotaped lecture format, the paper proposes two automated mechanisms to create such lectures without the intervention of a camera or video mixer operator. The first mechanism depends on the absence of mouse motion events; while the second mechanism depends on the instructor’s facial and hand detections.
