Since the late last century, it has experienced three stages of development:
1, from blackboard to whiteboard; 2. From writing whiteboard to electronic whiteboard; 3. From electronic whiteboard to interactive electronic whiteboard.
Now when we talk about electronic whiteboard, we mean this kind of interactive electronic whiteboard, also called intelligent electronic whiteboard.
To put it bluntly, the interactive electronic whiteboard is to map the effective layout of the electronic whiteboard to the computer desk displayed by the display to play the role of the display, but the electronic whiteboard itself will not shine like the display. What should I do? You need a projector to project the computer desktop onto the electronic whiteboard.
In the above process, the electronic whiteboard plays the same role as the projection curtain.
The main differences are as follows:
This is the origin of the word interaction. After the projector projects the computer desktop onto the electronic whiteboard, the effective layout of the electronic whiteboard is associated with the desktop displayed by the display through the software and driver of the electronic whiteboard, which has a name in the field of electronic whiteboard called "positioning". After positioning, the content projected by the projector on the electronic whiteboard is consistent with the computer desktop displayed on the display.
You can use the following interactive functions of the electronic whiteboard, such as double-clicking the "My Computer" icon on the electronic whiteboard (depending on the technical means of the electronic whiteboard, such as electromagnetic, infrared, ultrasonic, optical imaging and other technologies, the double-clicking operation mode will be different, for example, the electromagnetic type uses an electromagnetic induction pen, and the infrared type only needs one hand ...), and then my computer icon will open, allowing you to operate the computer on the electronic whiteboard.
In addition, the installation software of electronic whiteboard will include many self-contained software, such as multimedia teaching courseware, marking tools for documents and pictures, handwriting recognition tools and so on.
The above is a simple description of the realization process of electronic whiteboard.
