Description

technical field [0001] The invention relates to the field of multimedia teaching, in particular to a computer multimedia distance education training teaching device. Background technique [0002] With the advancement of science and technology and the development of information technology, the traditional teaching mode is undergoing major changes. Relying on traditional blackboard chalk as a teaching tool can no longer meet the requirements of modern university education, training and teaching. Especially with the development of computer technology and projector technology, computer multimedia teaching has gradually replaced the traditional teaching method of blackboard chalk, and has achieved good application results. At present, there are two commonly used computer multimedia teaching methods. One method is a projector plus a computer. The projector is hoisted in the air indoors, the screen is hung on the wall, and the computer is placed on the teacher's platform. The co...

Problems solved by technology

[0003] The problem with the first method is that, first of all, there is a certain distance from the projector to the screen, and the brightness and true color of the projection will be lost in the air, and the high-brightness projection bulb is too heavy and easily damaged. , the bulb is expensive, and the school cannot afford to replace it in a short time; secondly, using this kind of device requires a large space, and now the general classroom space is not enough, and sometimes the teacher blocks the projection, which affects the teaching effect. In addition, the device is scattered , need manual storage

The problem with the second method is that, first of all, the rear projection technology uses the principle of reflection projection, and the reflection needs a certain space, which itself consumes too much energy; Projection reflection space (rear projection thickness), the thickness is too large, it cannot be placed in general classrooms

In short, there are many deficiencies in the existing multimedia teaching and training methods and devices, which can only be used in special classrooms and kept by special personnel, but have not been widely used in general classrooms
