Interactive Whiteboards

An interactive whiteboard is also called an electronic whiteboard or a digital whiteboard. An interactive whiteboard is an improvement on the whiteboards of old that were used by businesses and classrooms. The interactive whiteboard connects to a computer via a USB port. Some will have Bluetooth technology as well. The whiteboard surface is sensitive to touch and you can write or draw on the surface with your hand or various types of writing or drawing device. They come with computer software and whatever you draw or write on the surface can be stored for later use. Some users write on the whiteboard with special markers or use a wand. These boards are usually very large and can measure from 10 to 15 feet. If you need to erase or make changes on a drawing, diagram, etc, you can use dry erase markers on them just as you can on a standard non-interactive whiteboard. The interactive whiteboard can be mounted on the wall or you can place one on a floor stand.

This type of whiteboard needs both a computer and a digital projector for operation. They are replacing old fashioned chalkboards in classrooms, boardrooms, offices, etc. One can be installed for a little less than $1000. Many offices and meeting rooms make use of interactive whiteboards during business meetings and sales presentations. They are even being used in athletic training rooms now as well. Since they are interactive you can use them for all kinds of things. Highlighting a point in a presentation, editing a movie, demonstrations during teaching lessons to demonstrating the way sport plays should be done are a few examples of how they can be used. You can print out the information that is on the board to share with others or save it on your computer.

There are different types of interactive whiteboards on the market. These types are analog resistive, electromagnetic, infrared or optical, ultra-sonic, optical and infrared or IR whiteboards. They will either have a front or rear projector on them. The projector displays what is on your computer onto the whiteboard. You can use an emulated on screen keyboard to type on the whiteboard or make use of its handwriting recognition software. This allows the user to easily enter text as needed. The user can control the computer display via mouse and keyboard emulation as well. Highlighting options are available as well as virtual rulers, protractors, compasses and other such virtual classroom teaching tools.

The analog resistive interactive whiteboard uses two sets of resistive materials on the surface that generates electricity upon contact to locate the position of the stylus on the board. The electromagnetic interactive whiteboard is the most popular. It uses a special marker with a coil that generates electrical signals to write on the board. The infrared optical interactive whiteboard uses a triangulation algorithm and an infrared light to locate the maker on the board. Any kind of marker can be used.

The ultra-sonic-based interactive whiteboard uses ultrasonic sound to locate the marker on the board. Whenever a stylus is pressed on the board surface the sound is picked up by microphones okay to have different positions on the board. A laser-based interactive whiteboard is similar to the infrared optical whiteboard. However it uses a laser-based system to locate the marker on the board.

You can buy interactive whiteboards in bundles that come with a digital projector and speakers. A front projector interactive whiteboard is less expensive than a rear projector interactive whiteboard. Before you buy the projector for a specific purpose you should check with whiteboard supplier to determine what kind of projector it needs. You should also take into consideration the room size and type of presentation you will be doing before you buy your interactive whiteboard.
