What is Interactive Whiteboard
Interactive Whiteboard is an advanced education or human-computer interaction devices supporting the meeting, it can come true dust-free writing, free writing remote exchange communication function by which ties in with the projector and computer applications and so on. It has a variety of series by the instruction form, such as rear projection board, front-mount projection board, writing board and so on. In hardware principle, it perfectly integrates Large-screen projection technology with highly-precise orientation technology. At this stage of the international and domestic markets, there are a variety of techniques to achieve accurate positioning of the whiteboard, for example Infrared technology, Electromagnetic Technology, Resistor technology, Ultrasound technology, CCD and so on. Each technology has different characteristics and advantages, as well as in the whiteboard market, shares certain.
Basic Working Principle
Radio frequency (RF) theory, whiteboard plate is installed inside the sensor, Acceptance issued by a special electromagnetic pen-frequency signals to achieve positioning
Advantages for Electromagnetic Whiteboard
Highly-precise pinpoint spot
High reliable and long lifetime
Response speed
Writing process with a sense of pressure
Marker support the right mouse button functions, easy to operate computer
Major Functions
1. Interactive function: You can operate the PC directly on the whiteboard and vice verse.
2. Editing objects function: You can edit any object(including your written ones) on the board such as color change, edit the thickness of line, copy plater, move zoom in&out, revolve, transfigure, overturnverticallyandhorizontally, combine, separate, delamination, save and set hyperlink etc.
3. Handwriting recognition: It can recognize your handwriting notes as standard typed text ones including Chinese and English.
4. Dynamic saving function: You can save all of your operations on the board as a dynamical video and play it little without using any other particular media players.
Application Fields:
It can be largely used in schools of all levels, all kinds of training institutions in military, enterprises and other industries.
