Multi-media electronic reciprocal teaching system

Abstract

The invention relates to a multi-media electronic reciprocal teaching system which belongs to the technical field of multi-media electronic reciprocal teaching and comprises a large-screen reciprocal touch display, a stereoscopic display, acoustic equipment, a control host computer, network equipment and courseware. Any one computer is connected with the large-screen reciprocal touch display through a USB interface and connected with the large-screen reciprocal touch display through a video cable, the audio output of the computer is connected with the acoustic equipment, the computer is connected to a campus network for calling the courseware; the control host computer is connected to the stereoscopic display through a video cable, the audio output of the control host computer is connected with the acoustic equipment; and the host computer is connected with the campus network for realizing calling the stereoscopic courseware. The invention can be widely applied to occasions of classrooms in schools, studios in television stations, meeting rooms in large companies, exhibition, scheduling and directing places and the like.

Description

technical field [0001] The invention belongs to the technical field of multimedia electronic interactive teaching, and in particular provides a multimedia electronic interactive teaching system, which can be widely used in school classrooms, TV studios, large-scale enterprise meeting rooms, exhibitions, dispatching and commanding and other places. Background technique [0002] Today, with the rapid development of science and technology, information technology and multimedia technology have increasingly affected various fields. In the education industry, from traditional blackboards to whiteboards, from whiteboards to electronic whiteboards, teaching equipment has been developing in the direction of digitization, informationization, and networking. Interactive teaching methods have been greatly promoted, and digital interactive teaching equipment is also developing day by day. Interactive digital multimedia teaching equipment has been widely used in the United States and many...

Problems solved by technology

[0008] Touch screen system, stereo display system, sound reinforcement system, and multimedia courseware have been widely used as individual technical fragments or products in teaching systems at home and abroad, but they have not been widely used as a complete system, mainly because of The front projection system is limited by the interference of brightness and natural light, so it is not suitable for widespread application in the education industry. The rear projection or flat panel touch screen display system and the stereoscopic display system are limited by the thickness, size and price of the display screen, which also directly restricts the display. The system is widely promoted in the education industry, and a small number of local users cannot stimulate the interest of companies with multimedia courseware production capabilities. The vividness and interactivity of the courseware produced by non-professional teachers are very poor, and the art skills are also poor. The traditional multimedia courseware cannot achieve interaction, nor can it stimulate students' interest in learning. It is not even as vivid as the blackboard-style education. It is an incomplete technology that is partial and lacks effective integration of technology applications, and cannot drive the development of an industry, let alone a A revolution in the technology or model of the industry

Individual segmented applications cannot realize the huge potential of advanced equipment. Advanced equipment is only used in simple applications in many schools, and the use of equipment capabilities is even less than 10% of equipment functions, which greatly wastes limited funds and equipment resources.

[0009] The so-called multimedia electronic teaching system in China is just a slide teaching method, which is basically a projector plus a front projection screen, and the brightness of the projector is very low, and the general design brightness is only 100cd / m 2 , and the classroom is bright, the design illuminance is 500cd / m 2 , and the front natural light has a great influence on the front projection light, the contrast of the screen image is extremely poor, the cost of the projector bulb is high, and the school cannot afford to replace it. It is better to call it a decoration for inspection or leadership than to call it multimedia teaching.

There is a huge gap between domestic and foreign countries. Foreign developed countries have basically abandoned the traditional projector mode and almost completely changed to high-brightness liquid crystal or plasma flat-panel touch screen systems and stereoscopic display systems. It is a pity to waste limited education funds by configuring a projector system that is almost useless
