What is an electronic whiteboard? What is the function of the electronic whiteboard?

What is the basic parameters of the electronic whiteboard interactive whiteboard, electronic whiteboard knowledge Daquan

The interactive whiteboard can communicate with the computer, connect the electronic whiteboard to the PC, and use the projector to project the contents of the PC onto the electronic whiteboard screen. With the support of a dedicated application, a large screen can be constructed and interacted with. Collaborative meeting or teaching environment. Using a specific stylus instead of a mouse to operate on a whiteboard, you can run any application that can edit, annotate, save, etc. any operation that can be done on the computer using the keyboard and mouse.

The interactive whiteboard also supports copying, connecting the whiteboard directly to the printer, and using a specific whiteboard pen to print the book. 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 PC whiteboard to connect the electronic whiteboard to the PC. At this time, the electronic whiteboard is equivalent to a particularly large tablet, which can be written, drawn and instantly displayed on the PC. The file is saved as a graphic file. . This feature generally requires a dedicated application support. If you use a specific application such as MICROSOFT's NTEMEETING, the interactive whiteboard can communicate with other offices and conference rooms through the network to realize web conferences.

The interactive whiteboard is an advanced educational or conference-assisted human-computer interaction device. It can be used with projectors, computers and other tools to achieve functions such as dust-free writing, free writing, and remote communication. From the structural shape, there are various forms such as front projection, rear projection, and writing board; from the hardware principle, the interactive whiteboard incorporates large-screen projection technology and precise positioning test technology. At this stage of the international or domestic market, there are a variety of technologies that can achieve accurate positioning of electronic whiteboards, representative of infrared, electromagnetic induction, resistance, ultrasonic, CCD and other technologies. Each technology has different characteristics and advantages and has a certain share in the market. According to the analysis report of the international authoritative market research institute, in recent years, electronic whiteboards using electromagnetic induction technology have gradually dominated the market in the international market. Antarctica and Antarc account for more than 1/2 of the market share, followed by infrared sensing and ultrasound. Sensing technology, which accounts for about 1/6 of the market share.

Interactive whiteboard basic parameters

1) Computer interface: The interface type refers to the way in which the electronic whiteboard and the computer system are connected. Common interface types are parallel port (also known as IEEE 1284) and serial port (also known as RS-232 interface) and USB interface. Technology determines the core quality of an electronic whiteboard, but a single technology does not represent the entire product.

2) Stability: Stability refers to the stability of the entire product (including hardware). With the help of market experience and the experience of old users, it is easy to judge the stability of the product;

3) Sensitivity: draw a line on the whiteboard. If the continuity of the line is not strong, it means that the sensitivity is not high;

4) Accuracy: Accuracy refers to the degree of coincidence of the mouse cursor tip and the stylus tip after calibration;

5) Resolution: Resolution refers to the number of points (or pixels) on each line. Usually the number of points is represented along the horizontal and vertical edges of a screen or monitor;

6) Output mode: The electronic whiteboard can scan and print the content written on the whiteboard in a certain way. The way of printing output is generally thermal, inkjet and ribbon;

7) Number of panels: Under normal circumstances, the electronic whiteboard will be equipped with 1-4 panels, and the number of panels will be more than 2 to facilitate screen circulation;

8) Panel size: refers to the actual size of the electronic whiteboard, the unit is mm, usually refers to the length × width of the electronic whiteboard;

9) Effective reading size: refers to the effective size that the electronic whiteboard can be used for writing. In this area, it can be arbitrarily written and copied, and its size is generally smaller than the actual panel size;

10) Copy speed: Copy speed refers to the number of sheets that the electronic whiteboard can copy every minute. Its unit is Zhang/min;

11) Continuous copy number: Continuous copy refers to the maximum number of copies of the same manuscript that need not be set multiple times, and the electronic whiteboard can be continuously completed at one time, representing the maximum ability of the product to be continuously copied.
