Description
Summary:The open courseware proposed by MIT with single streaming video has been widely accepted by most of the universities as their supplementary learning contents. In this streaming video, a digital video camera is used to capture the speaker's gesture and his/her PowerPoint presentation at the same time. However, the blurry content of PowerPoint slice in this recorded video isn't rich enough for students' further learning. This motivates us to find a novel approach to integrate the details of teacher's gesture and presentation with digital video camera and screen catcher, respectively. Due to the integration technologies of multimedia applied in this paper, this proposed method can significantly improve the quality of streaming video especially the content of PowerPoint and moving data on PC screen. In addition, the variety of scenes occurred inside a classroom can be easily directed and then recorded for future learning. A utilized experimental design was applied to check the degree of clarity and validate the learning effectiveness. The results showed that the proposed method was much better than the conventional method that with only one single digital video camera.
