Varieties of Interactive Whiteboards

An interactive whiteboard can be described as the modern equivalent to a traditional classroom chalkboard. A whiteboard is basically a large computer screen that has the ability to receive information from a special pen that is designed to be applied to the board. The whiteboard is commonly mounted on a wall or on a stand in the classroom. A whiteboard is not only used in classroom environments. Interactive whiteboards are being used in corporate settings, broadcasting studios and professional coaching environments.

Let's discuss how the whiteboard actually works. For more info about interactive whiteboards, follow the link. First, you'll need a computer to connect to the whiteboard through either a serial cable, a Bluetooth, USB or Wi-Fi connection. The screen also serves as an HID, or human interface device. Some higher end whiteboards have applications for hand writing or an onscreen keyboard. With the hand writing application or keyboard, a user reduces the need for computer interface.

Additionally, a whiteboard may feature digital versions of protractors, compasses, rulers and other learning tools. When considering their operation modes, whiteboards can be grouped into three different categories.

The first group of whiteboards are those that perform on the basis of resistive touch. A membrane that is transparent covers the entire surface area of the board. When a user presses against the membrane, the membrane then touches against a conducting plate that is behind the screen. This transaction is essentially the equivalent to a mouse click. This type of operation tends to be the easiest and most simple way to operate an interactive whiteboard.

The electromagnetic pen system is similar to the resistive touch principle, yet a different way to operate a whiteboard. The pen is very easy to use, it does not rely on batteries or electric switches. When brought very close to the board, the pen will modify signals emitted from the board's surface. More advanced versions of the electromagnetic pen possess mouse-like capabilities in that the user can click points for more detail and accuracy. The electromagnetic pen mode of operation is the type of whiteboard most used by designers, architects, and artists.

The final category for whiteboard operation is an IR based interactive process. It is generally the most expensive type of whiteboard available. Follow the link for more information on a portable interactive whiteboard. An infrared camera tracks invisible lines and dots created by a pen or remote on the whiteboard. Just like the electromagnetic pen system, the IR system's remote is very similar to a computer mouse.

Many believe that a classroom or work environment is invigorated by a whiteboard because the audience is more responsive and it provides people with a fun, more advance learning tool.
