Interactive Whiteboards: The SmartBoard


Todays Smart Classrooms equipped with various digital technologies including Interactive Whiteboards, Visualizers, Document Cameras, Interactive Panels, Digital Power Lecterns, Podiums, Projectors and room wizards etc. Interactive Whiteboard also termed as Smart Boards can turns your computer and projector into a powerful tool of teaching, collaborating, learning and presenting.  With a Computer image projected on to the Board, you can simply press on its large, touch-sensitive surface to access and control any application. White Boards like interactive white boards are transforming classrooms into vibrant, welcoming environments where students are granted the freedom to learn like they think and express their own new innovative ideas in this modern technology era.

White Boards can be directly connect to a Computer/Laptop and Projection System acts, as a digitally interactive white board where one does not needs any marker to write or highlight any information. Using a finger, one can work naturally at the Board to take notes and highlight important and desired information. Whenever you meet, teach, train or present, the Board helps your group save your precious time, increase interactivity within your group members and improve communication that leads to emergence of modern world.

You can also control all the computer functions from the Board itself and thus no need to stand near your Computer while presenting, teaching or collaborating something to students. Besides this one can choose a number of colors to present the information and there is no limitation on the colors of markers one have.

The Smart Board is an interactive whiteboard that make use of touch detection for user input. This includes scrolling, right mouse-click in the same way normal PC input devices, such as a mouse or keyboard, detect input. The Smart Board interactive whiteboard typically comes with four pens, which use digital ink and replace traditional whiteboard markers. Most Smart Board interactive whiteboards register only one touch at a time. Some dual-touch Smart Board interactive whiteboard accepts two simultaneous touches.

A Smart Board Interactive Whiteboard may also be used in non-projected mode (without using a projector), but using them with projector is what making Classroom Smart and interactive. We can use a whiteboard in projected mode with having three main components:

  • §   A Computer System
  • §   A Digital Projector
  • §   A SMART Board Interactive Whiteboard

All these three components work together to make an Interactive Smart Classroom as

The Smart Board uses DViT (Digital Vision Touch) technology to detect and respond to touch interactions on the surface of interactive whiteboards. This camera-based touch technology for interactive whiteboards and interactive displays uses digital cameras and proprietary software and firmware to detect finger or pen contact with the screen. 

With this new generation digital smartboard users can easily and interactively engage themselves in drawing diagrams, opening images and videos, exploring internet or illustrate their points by writing directly on it and express them in an interactive manner that will also facilitate the viewers.

Today, the SMART Boards is used to teach over 18 million students and participants in more than 600,000 classrooms in more than 100 countries around the whole world. The interactive nature of the Smart Boards provides many practical uses for the classroom learning and education. Now one can be able to show the presentation with high quality and desired dimensions that will increase level of communication and education standard also. Smart Board allows users to work with large amounts of information. It brings you a flexible collaboration tool that transforms every lesson or brainstorming session into a dynamic learning experience.

Interactive Whiteboard: Future of Classroom Learning


Interactive Whiteboard: Future of Classroom Learning


Are Interactive Whiteboards really helpful in Classroom Education, Corporate Systems and Broadcasting Studios? A lot more questions are puzzling our minds. So, let just try to find it out….

An interactive display which connects a computer to the projector is widely known as an interactive whiteboard (IWB). An interactive whiteboard is a combination of computer and projector where projector projects the desktop over the board’s surface where operator controls it by the help of pen, finger, or other device. This is just a kind of board which is required to be mounted over a wall or floor stand. It is widely used in classrooms for running software which is to be loaded onto the connected PC such as web browsers or proprietary software, capturing notes written on a graphic tablet connected to the whiteboard, OCR software to translate cursive writing on a graphics tablet into text, audience response system so that presenters can poll, conduct quizzes, capturing feedback onto the whiteboard.

According to market research by Future source Consultancy it was confirmed that interactive whiteboard industry was expected to reach sales of US$ 1 Billion worldwide by 2008 and by 2011; one of every seven classroom in world will feature interactive whiteboard.

This device is basically connected to a computer via USB or port cable or Bluetooth or even via 2.4 GHz wireless. Interactive whiteboard act as a Human Input Device (HID), like a mouse when it is to be attached to the computer.  The video output is needed to be connected to a digital projector so that images can appear over the whiteboard surface. Now the user can calibrates the whiteboard image via pointer and this is the device which is to be required for the activation of programs, buttons and menus from the whiteboard itself. 

All over the Globe there are four common types of operations which used by the users. These are the operations which develops interaction between the user and the content projected on the whiteboard. These are an infrared scan technology, an electromagnetic pen, a resistive touch-based board, a portable ultrasonic pen, and wiimote.
Today, interactive whiteboards are replacing the traditional whiteboards or flipcharts or even media systems. The software supplied with the interactive whiteboard will usually allow the teacher to keep notes and annotations as an electronic file for later distribution either on paper or through a number of electronic formats. Many companies and projects now focus on creating supplemental instructional materials specifically designed for interactive whiteboards. Electro kite out of Boston, MA, for example, will have the first complete curriculum for schools and districts.

But, According to Larry Cuban, education professor emeritus at Stanford University, "There is hardly any research that will show clearly that any interactive whiteboards will improve academic achievement.

Today also interactive whiteboards are still a question mark. Undoubtedly, they are helpful but not everywhere and needs to be discussed some more.
