Construction of a Course Video Resource System Based on Students´ Visual Attention

A course video resource system based on non-classroom students´ visual attention can present the course video resources to non-classroom students and provide them with the teaching information they require in their studies, thereby effectively promoting learning. This paper analyzes the focal points of the visual attention of classroom and non-classroom students, examines the various ways used by teachers of different instructional styles to guide students´ visual attention, and presents concepts for effectively manipulating the camera lens to guide students´ visual attention. Moreover, the paper suggests the use of phonetic recognition, board-writing recognition, and light-spot information overlapping methods to control of the application of the camera lens and the channel switch of video material flows, so that the course video resources presented to non-classroom students fit their visual attention, thereby enhancing the efficiency of the utilization of course video resources and boosting the efficiency of student learning. At present, no device for building such a course video resource system exists; thus, IT enterprises may develop such devices using this idea to satisfy the learning needs of non-classroom students.
