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.
