What is an electronic whiteboard?
The electronic whiteboard is a high-tech product developed by a combination of cutting-edge electronic technology, software technology and Other high-tech methods. It can realize paperless office and teaching by applying the principle of electromagnetic induction, combined with computers and projectors. Electronic whiteboards are developed from ordinary whiteboards. The earliest electronic whiteboards were copy-type electronic whiteboards. With the development of technology and market demand, interactive electronic whiteboards have appeared. At present, these two types of electronic whiteboards coexist in the market. The two types of electronic whiteboards are introduced below.
Copy-type electronic whiteboard: The so-called copy-type electronic whiteboard means that the content written on the whiteboard can be scanned and printed in a certain way through a simple operation of the user. The function completion process is the same as the ordinary copy process. First, the image sensor device collects the content on the whiteboard. After a certain image processing, the collected signal is finally output by thermal, inkjet or other printing methods.
The output paper is generally A4 format. The image sensor device of this electronic whiteboard is generally CCD, and the scanning mode adopts CCD module movement or whiteboard film movement. The printout methods generally include thermal paper output and inkjet plain paper output, and there are two types of colors: black and white and color output. In addition to the copy function, some manufacturers have added the function of connecting to a computer on this basis, which can scan the content of the whiteboard into the computer, and the function is equivalent to a scanner. At present, manufacturers of copying electronic whiteboards include Panasonic and Prex of Japan, etc., which are priced at around 10,000.
Interactive whiteboard: The interactive whiteboard can communicate with the computer, connect the whiteboard to the PC, and use the projector to project the content on the PC to the whiteboard screen. With the support of special applications, it can be constructed A large screen, interactive collaborative meeting or teaching environment. Using a specific pointing pen instead of a mouse to operate on the whiteboard, you can run any application, edit, annotate, save, etc. any operation that can be achieved on the computer using the keyboard and mouse.
The interactive electronic whiteboard also supports copying. The electronic whiteboard is directly connected to the printer and used for writing on a specific whiteboard pen. When you need to print, just press the print button on the panel to achieve color or black and white printing. It can also be used as a PC whiteboard, connecting the electronic whiteboard to the PC. At this time, the electronic whiteboard is equivalent to a particularly large handwriting board. It can be arbitrarily written, drawn and displayed on the PC at any time. The file is saved as a graphic file . This feature generally requires a dedicated application support. If through a specific application such as MICROSOFT's NETMEETING, the interactive electronic whiteboard can communicate with other offices and meeting rooms through the network to achieve network meetings.
Working principle: The working principle of electronic whiteboard is divided into pressure sensing principle and laser tracking principle. A touch-type whiteboard using the pressure-sensing principle is equivalent to a touch screen of a computer. It is a human-computer interactive input device that uses a finger or a pen to touch the options displayed on the screen to complete a specified job. This electronic whiteboard has two layers of pressure sensitive film. When a point on the surface of the whiteboard is stressed, the two layers of film cause a short circuit at this point. The controller of the electronic whiteboard detects the coordinate value of the pressed point (finger or pen) Location), sent to the computer via the RS232 interface. A laser transmitter is used on both sides of the upper end of the whiteboard using the principle of laser tracking. After the whiteboard is started, the laser transmitter emits laser light to scan the surface of the whiteboard, and the special pen has the function of sensing laser to feedback the position of the pen.
According to the type of installation, it can be divided into: wall-mounted type, slide type, mobile type and closet type.
