An automated authoring system by means of integrating e-Meeting and e-Learning to support higher education under the WebELS platform

This paper presents the concept and implementation of an automated authoring system, to integrate two different modules e-Meeting and e-Learning of the WebELS platform. The primary function of the proposed system is to synchronize the lecturer video stream with the presentation slides in a real-time processing. The system automatically detects the events of slide changing and cursor positions and links them to the exact position of the video. Thus the video is synchronized with the sequence of slides and cursor data, which the students follow on the real-time presentation. This approach is very valuable for students who did not grasp some specific topics, to repeat the important parts of the presentation. Moreover, students who were not able to attend the live presentation, can access to the learning contents created at the server side for later reviewing. The evaluation of criteria for the proposed system demonstrates its usefulness and effectiveness in developing rich eLearning contents to support higher education.
