Abstract

The invention relates to a method for automatically recording classroom teaching in the multi-media moving teaching field. According to the method, an iPad terminal device is adopted and is connected with a projector, and the method for automatically recording classroom teaching is achieved by the following steps of: 1) writing teaching content by virtue of a drawing board interface provided by the iPad terminal device; 2) tracking the content drawn by a teacher in the drawing board interface by adopting a gesture touch detecting technology, and tracking the state of the finger or a writing pen through a touch call-back method provided by an ios system; 3) achieving the purpose of drawing on the drawing board interface randomly by using the coregraphics technology in the ios; 4) recording the marking trajectory of the finger of the teacher or the writing pen, establishing an image buffering area with a certain frequency, and organizing data into a static image from the image buffering area through the image generating technology; 5) and converting the real image in the drawing board interface into frames of the video through an audio / video coding technology to obtain a section of complete video, thus finishing recording of classroom teaching content.

[0002] With the rapid development of the Internet and mobile devices, the degree of social informatization is getting higher and higher. However, in the education industry, traditional paper textbooks and blackboard writing still occupy the mainstream. This traditional teaching method has become more and more exposed. its disadvantages

The traditional teaching method requires a lot of textbooks and blackboard writing, which wastes paper resources and the cost of purchasing teaching facilities such as blackboards and chalk. Moreover, the traditional teaching method cannot simply and effectively record the class process, which is not conducive to students' class Review and self-improvement by teachers

Although some schools have adopted modern teaching facilities, such as the use of projectors for teaching, although this has improved the vividness of the lessons, teachers still need to use traditional writing on the blackboard for teaching, which has caused a disconnect between courseware and writing on the blackboard. holistic and does not address the purpose of recording the classroom as a whole
