Information
As a new type of teaching instrument, interactive electronic whiteboard has received the favor of many educators and even the whole education industry and teaching instrument providers.
 
The following is an introduction to the interactive electronic whiteboard:
 
The interactive electronic whiteboard can communicate directly with the computer, connect the electronic whiteboard to the computer, and use the projector to project the contents of the computer onto the electronic whiteboard screen. With the support of special applications, a large screen, interactive collaborative meeting or teaching environment can be constructed.
Using a special positioning pen instead of a mouse to operate on the whiteboard, you can run any application, you can edit, comment, save files, and so on on the computer keyboard and mouse can achieve any operation.
 
Teaching instrument composition
 
Integration of hardware White Board and software White Board operating system.
Its core components are made up of electronic induction whiteboard, induction pen, computer and projector.
The electronic induction whiteboard is a large induction screen with normal blackboard size and working under the support of computer software and hardware, which ACTS as a computer monitor and replaces the traditional blackboard.
The electronic induction pen takes on the double function of the electronic whiteboard writing pen and the computer mouse, which replaces the traditional chalk.
Teachers or students operate directly on the whiteboard with induction pen (equivalent to traditional teaching teachers and students operate on the blackboard with chalk) : write or call various software, and then feed back to the computer through electromagnetic induction and quickly project to the electronic whiteboard through the projector.
Whiteboard operating system is a software platform that exist in a computer, not only does it support person and board, the exchange of information between computers, projectors, and it also bring a powerful and resources to make the material library tool library, and is a compatible with operating a variety of software, intelligent operation platform, teacher can call all kinds of material in a whiteboard or application teaching.
Whiteboard sets the traditional blackboard, computer, projector and other functions in one, so that teachers use very convenient.
 
Advantages of teaching instruments
 
The interactive electronic whiteboard also supports photocopying. The electronic whiteboard is directly connected to the printer and written on board with a special whiteboard pen. When printing is needed, you only need to press the print key on the panel to achieve color or black and white printing.
It can also be used as an electronic whiteboard for teaching. The electronic whiteboard is connected with the computer. At this time, the electronic whiteboard is like a handwriting board with a large area.
This feature typically requires a dedicated application support.
With a specific application, the interactive electronic whiteboard can communicate with other offices and conference rooms through the network, realizing network meeting and remote teaching.
 
Interactive electronic whiteboard according to the principle can be divided into five categories: electromagnetic induction, infrared, ultrasonic, resistance pressure sense, CCD and so on.
 
technology
 
Divided into electromagnetic induction type, infrared induction type, pressure induction type, ultrasonic induction type, image sensing type.
Each technology has different characteristics and advantages and occupies a certain share in the market.
The analysis report of international authoritative market investigation organization shows, on recent years international market, the electronic whiteboard that USES infrared induction technology and electromagnetism induction technology occupies market dominant position gradually, hold the market cent forehead of 1/2 above, it is pressure feeling and ultrasonic sensing technology next, hold the market cent forehead of about 1/6.
Abroad there are panasonic, Toshiba, prusch chuangyou and other brands, domestic well-known brands eduborad, Antarctica, Antarc, honghe, dragon and other brands.
According to the principle of hardware is divided into: ultrasonic type, electromagnetic induction type, infrared type, resistance pressure type: electromagnetic electronic whiteboard slowly become the mainstream.
Electromagnetic induction type
 
Basic principle: radio frequency (RF) principle, a sensor installed in the core of the whiteboard, to receive the electromagnetic pen issued a specific frequency signal to achieve positioning.
 
Advantages: accurate positioning, high accuracy, high reliability, long life, fast response, pressure feeling in the writing process, whiteboard pen support mouse right button and other functions, easy to achieve the operation of the computer.
 
Disadvantages: special pen must be used, maintenance is complex and not easy to operate, the human body radiation is large, not suitable for the human body, especially women, children long-term use.
 
Infrared technology
 
Basic principle: infrared principle, through the white board around the infrared tube detection block infrared light object to achieve positioning.
 
Advantages: accurate positioning, high accuracy, no need for special pens, long service life, faster response, simple maintenance, safety and environmental protection without radiation.
 
Disadvantages: no pressure response, basically no other disadvantages.
 
Teaching instrument resistance pressure sensing type
 
Basic principle: resistance film technology, through the detection of resistance value to achieve pressure sensing location.
 
Advantages: relatively accurate positioning, no need for a special pen.
 
Disadvantages: poor durability, fear of scratches, slow response speed, unable to do large area, whiteboard pen does not support the right mouse button and other functions, the operation of the computer is more difficult.
 
According to the installation type is divided into: wall-mounted type, slide type, mobile type, closet type.
 
Optical infrared type
 
Touch expert - interactive electronic whiteboard
 
Basic principles;
As with projectors, infrared devices are placed in front of the projected image to receive and transmit infrared signals.
Can adapt to 20-120 inch projection screen, the size of the projection screen changes.
Projectors will be projected on the screen or the wall projection screen can be realized on the operation of the computer.
