Copy electronic whiteboard: the so-called copy electronic whiteboard is to scan and print the contents written on the whiteboard in a certain way through the simple operation of the user. The function completion process is the same as the ordinary copy process. First, the image sensor collects the contents on the whiteboard. After some image processing, the collected signals are finally output by thermal, inkjet or other printing methods.
The output paper is generally A4 format. The image sensor of this electronic whiteboard is generally CCD, and the scanning mode adopts CCD module movement or whiteboard film movement. Print output methods generally include thermal paper output and inkjet plain paper output, and color output includes black and white and color. In addition to the copy function, some manufacturers have also added the function of connecting with a computer, which can scan the contents of the whiteboard into the computer, and the function is equivalent to a scanner. At present, the manufacturers of copying electronic whiteboard are Panasonic and Cong of Japan, and the price is around 10 thousand.
Interactive whiteboard: The interactive whiteboard can communicate with the computer, connect the whiteboard to the PC, and use the projector to project the contents of the PC onto the screen of the whiteboard. With the support of special applications, a large-screen interactive collaborative meeting or teaching environment can be constructed. Using a special stylus instead of mouse to operate on the whiteboard, you can run any application, edit, annotate and save files, and other operations that can be realized by using the keyboard and mouse on the computer.
Interactive whiteboard also supports copying. The electronic whiteboard is directly connected to the printer, and books are written on the blackboard through a specific whiteboard pen. When you need to print, just press the print button on the panel to print in color or black and white. It can also be used as a PC whiteboard to connect the electronic whiteboard with the PC. At this time, the electronic whiteboard is equivalent to a particularly large handwriting board, which can be used to write and draw at will, immediately displayed on the PC, and the file is saved as a graphic file. This feature usually requires dedicated application support. If you use a specific application, such as Microsoft's NETMEETING, the interactive whiteboard can communicate with other offices and conference rooms through the network to realize the network meeting.
Working principle: The working principle of electronic whiteboard can be divided into pressure sensing principle and laser tracking principle. The touch whiteboard based on the principle of pressure sensing is equivalent to the touch screen of a computer. It is a human-computer interactive input device that uses fingers or strokes and the options displayed on the screen to complete the specified work. There are two layers of pressure-sensitive adhesive films inside the electronic whiteboard. When a certain point on the surface of the whiteboard is pressed, the two films cause a short circuit at that point. The controller of the electronic whiteboard detects the coordinate values of the pressing points (where the fingers or strokes reach) and sends them to the computer through RS232 interface. Based on the principle of laser tracking, there are two laser emitters on both sides of the upper end of the whiteboard. After the whiteboard is started, the laser emitter emits laser to sweep the surface of the whiteboard, and the special pen has the function of sensing laser, thus feeding back the position of the pen.
According to the installation type, it is divided into: wall-mounted, slideway, mobile and closet.
IBoard interactive electronic whiteboard is developed and produced by Shenzhen Abbott Technology Co., Ltd., with independent intellectual property rights and patented technology, and is widely used in high-tech products such as education, training, conference, information release, military command and remote cooperation.
The iBoard interactive electronic whiteboard is connected to the computer through USB interface, and the display content on the computer is projected onto the electronic whiteboard through the projector. With the support of special applications, a large-screen interactive collaborative conference or teaching environment can be built to realize paperless conference and teaching.
