The development of interactive electronic whiteboard
Since the end of the last century, people have been inventing and using whiteboards to avoid the health hazards of teachers and students caused by dust. In 1991, the electronic whiteboard series products first developed by Canadian SMART Company have been widely promoted and applied in the European and American markets, and achieved good economic benefits.
In the development history of the electronic whiteboard, the two-way interaction between the whiteboard and the computer, the presenter and the audience was really realized. In foreign countries, it was first developed by Canadian SMART company. Since 2005, with the gradual maturity of multimedia teaching conditions, domestic electronic whiteboards have gradually emerged, and the sales scale has gradually expanded. Since 2008, with the emergence of a large number of ultra-short and short-focus projectors in the projector market, the problem of projection light shading in the use of interactive electronic whiteboards has been effectively controlled, and the global demand for electronic whiteboards has expanded rapidly. The application of electronic whiteboards is also rapidly maturing, and the entire industry is also maturing rapidly.
Through the combination of hardware electronic whiteboard (WhiteBoard) and software whiteboard operating system. Its core components include electronic induction whiteboards, induction pens, computers and projectors. Electronic induction board refers to a large induction board with the size of an ordinary blackboard and supported by computer software and hardware. Its function is equivalent to a computer monitor and can replace the traditional blackboard. The electronic induction pen undertakes the dual functions of an electronic whiteboard pen and a computer mouse, and its role replaces the traditional chalk. Teachers or students use the induction pen to operate directly on the whiteboard (comparable to the operation of chalk on the blackboard in traditional teaching): write or call various software, and then feed back to the computer through electromagnetic induction, and then quickly project it to the electronic device through the projector. whiteboard. "Whiteboard Operating System" is a software platform that exists in computers. It not only supports information exchange between humans and whiteboards, computers, and projectors, but also comes with a powerful library of subject materials and resource production tools. , is an intelligent operation platform compatible with various software, which can be used by teachers to arbitrarily call various materials on the whiteboard or conduct application software teaching. It integrates traditional blackboard, computer, projector and other functions, making it very convenient for teachers to use.
The interactive electronic whiteboard also supports copying. The electronic whiteboard is directly connected to the printer, and is printed with a special whiteboard pen. When printing is required, just press and hold the print button on the panel to print in color or black and white. It can also be used as an electronic whiteboard for teaching, connecting the electronic whiteboard with the computer. At this time, the electronic whiteboard is equivalent to a particularly large handwriting board, which can write and draw at will, and immediately display it on the computer, and save the file in the form of graphics. . This feature usually requires dedicated application support. If there are special applications, it can interact with other offices and conference rooms through the network to realize network conferences and distance teaching.
