Embodiment Construction
[0029] The invention provides a video teaching system and method. The video teaching system preprocesses and saves the teaching video collected by the camera through electronic information processing equipment. Students can obtain the teaching content of the teacher's writing on the blackboard by watching the teaching video, and the teacher does not write on the blackboard. It will block the teaching content, and at the same time, students can communicate face-to-face with the teacher through the teaching video, achieve eye contact and improve communication efficiency. In order to make the object, technical solution and effect of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

The invention discloses a video teaching system and a method, and the system comprises an electronic information processing equipment, a transparent projection screen, and a camera, and the electronic information processing device is in communication connection with the camera. The transparent projection screen is used for a user to write teaching contents on a blackboard; the camera is used for collecting teaching videos of a user and transmitting the teaching videos to the electronic information processing equipment; wherein the teaching video comprises a front image of the user and the teaching content; the electronic information processing equipment is used for preprocessing and storing the teaching video. Students can simultaneously see the teaching content written on the blackboard by the teacher and the front image of the teacher by watching the teaching video, so that the teacher is prevented from shielding the teaching content written on the blackboard, the effect of direct face-to-face communication between the teacher and the students can be achieved, and the communication efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of video teaching, in particular to a video teaching system and method. Background technique [0002] With the popularization of the Internet, online education has gradually entered people's daily life. Online education includes recorded video teaching and online real-time teaching. Whether it is recorded video teaching or online real-time teaching, the teacher always faces the students when writing on the blackboard. In this way, on the one hand, the teaching content of blackboard writing will be blocked, and on the other hand, students can only see the back of the teacher, which cannot achieve the effect of face-to-face direct communication between teachers and students. [0003] Therefore, the prior art needs to be further improved. Contents of the invention [0004] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a video teaching system ...
