An interactive whiteboard can communicate with the computer by connecting the electronic whiteboard to the computer, and using the projector to project the contents of the computer onto the electronic whiteboard screen. With the support of a dedicated application, a large interacted screen can be constructed for collaborative meetings or teaching environments. Using a specific stylus instead of a mouse to operate on a whiteboard, you can run any application to edit, annotate, save files and other operations that can be done on the computer using the keyboard and mouse.
Since the late last century, people have begun to invent and use traditional writing whiteboards, mainly to prevent dust from invading the health of teachers and students. In 1991, the electronic whiteboard product was first developed by the SMART Company of Canada, and the electronic whiteboard was commercialized and promoted and used in the European and American markets.
The interactive whiteboard is a key step in the history of whiteboard development, and truly realizing the two-way interaction between whiteboard and computer, presenter and listener. In foreign countries, SMART Company took the lead in research and development. In 2001, Shenzhen Julong Science and Education Co., Ltd. took the lead in research and development of interactive whiteboard hardware and software. In the same year, it launched the first interactive whiteboard in China. Before 2004, The demand for electronic whiteboards is low in the domestic market, and the market is mainly occupied by famous brands such as SMART, Promethean, and Dragon Science. Beginning in 2005, with the gradual maturity of educational multimedia conditions, domestic electronic whiteboards began to emerge, gradually expanding the scale of sales. Since 2008, with the large-scale emergence of ultra-short-focus and short-throw projectors in the projector market, the problem of projection light blocking in the use of interactive whiteboards has been effectively controlled, and the demand for electronic whiteboards worldwide has expanded rapidly. The application of interactive whiteboards has matured rapidly and the industry has accelerated.
Integrated by the hardware electronic whiteboard and software whiteboard operating system. Interactive whiteboard’s core components consist of an electronic sensor whiteboard, sensor pen, computer, and projector. The electronic sensor whiteboard is a large sensor screen with a normal blackboard size working under the support of computer hardware and software. Its function is equivalent to a computer monitor and replaces the traditional blackboard. The electronic sensor pen takes on the dual function of the whiteboard pen and the computer mouse, replacing the traditional chalk. The teacher or student directly uses the sensor pen to operate on the whiteboard, and to write or call various software, then feedback to the computer through electromagnetic induction and quickly project to the electronic through the projector whiteboard, which is equivalent to the traditional teaching where the teacher and student use chalk to operate on the blackboard, . The whiteboard operating system is a software platform that exists in the computer. It not only supports the exchange of information between people and whiteboards, computers, projectors, but also comes with a powerful library of subject materials and resource production tools, and is a compatible with the intelligent operation platform for operating various software, teachers can freely call various materials or application software for teaching on the whiteboard. The interactive whiteboard is a combination of traditional blackboards, computers, projectors, etc., making it easier for teachers to use.
The interactive whiteboard also supports copying, connecting the whiteboard directly to the printer, and using a specific whiteboard pen to write. When printing, just press the print button on the panel to print in color or black and white. It can also be used as a teaching whiteboard to connect the electronic whiteboard to a computer. At this time, the electronic whiteboard is equivalent to a particularly large tablet, which can be written, drawn and instantly displayed on a computer. The file is then stored as a graphic file. This feature generally requires dedicated application support. If you use a specific application, the interactive whiteboard can communicate with other offices and conference rooms through the network to realize web conferencing and distance learning.
