Electronic lecturing system

Abstract

The invention relates to the technical field of multimedia systems, in particular to an electronic lecturing system. The electronic lecturing system comprises a computer mainframe, a touch control display screen, projection equipment, a projection screen, wherein the touch control display screen and the projection equipment are in data connection with the computer mainframe. According to the electronic lecturing system, the computer mainframe is controlled and information is input by hand through the touch control display screen, and the information is reflected onto the projection screen by the projection equipment in real time, so that paperless lecturing is realized with the adoption of an intelligent multimedia mode. The electronic lecturing system has the advantages as follows: 1, a teacher can completely get rid of blackboard-writing modes with a chalk, an ink pen and the like, and is kept away from the pollution of the traditional chalk powder, and a healthy and neat lecturing and learning environment is created; 2, with the adoption of the touch control display screen, the computer mainframe can be operated visually and conveniently; the teacher can input the information by hand freely in the course of explaining and demonstrating; the input information can be inserted into a lecture file with the real handwriting being reserved, and storage and calling are convenient; and 3, lecturing contents can be transferred in a paperless manner completely, so that low carbon and environmental protection are achieved, and the lecturing effects and the efficiency are improved.

Description

Technical field: [0001] The invention relates to the technical field of multimedia systems, in particular to an electronic teaching system. Background technique: [0002] The traditional teaching method is that the teacher directly writes on the blackboard with chalk, which is dusty and endangers the health of the teacher. The writing content is relatively simple, the expression method is rigid, and the writing content cannot be saved. When writing new content, the old content generally needs to be erased. With the widespread use of computers, a multimedia teaching mode composed of computers, audio and video playback equipment and projectors has appeared in teaching, conferences and other occasions. However, this teaching mode still has many shortcomings: 1. Teachers can only The prepared courseware is explained in the form of broadcast, and it is impossible to present the content of improvisation to the students.

With the widespread use of computers, a multimedia teaching mode composed of computers, audio and video playback equipment and projectors has appeared in teaching, conferences and other occasions. However, this teaching mode still has many shortcomings: 1. Teachers can only The prepared courseware is explained in the form of broadcast, and it is impossible to present the content of improvisation to the students. The lectures are monotonous and not vivid; moreover, it is impossible to record the wonderful performance of the teacher; Interaction; 3. In order to present the wonderful teaching content to the students, the teacher needs to prepare a lot of courseware, and the workload is very heavy
