The interactive whiteboard is a panel where interactivity is allowed and if you haven't seen this, you haven't seen anything yet. If you want to attract children to your class like never before, this is the perfect gimmick. With inter-activity in the class, you can be sure that you have just given students one more reason for coming to school, apart from the fact that mommy or daddy compelled them to go to school. All things considered, this is the cheapest way of presentation as compared to other deals in the market.

    Electronic whiteboards can be generally divided into two types, those using rear projection and those who use front projection. At the back is an digital whiteboard means that the projector is placed behind the panel surface. This ensures that no shadow is visible. Another advantage of this type of advice is that the presenter did not look into the light from the projector when talking to the audience. Although these tips are beneficial, they also have shortcomings. For example, theseinteractive whiteboards are very expensive compared to front projection.

    Second, they are too big. Finally, it is not possible to install this type of counsel against the wall. The board of white front projection uses a projector placed before the council. Most people who have used this whiteboard have complained about their shadows cast into the surface of the board. If you receive this type of interactive whiteboard you have to offset the shadow by extending your arms.

Some manufacturers have also devised a way to address this problem by using projectors UST is placed slightly above the interactive white board surface. This ensures that the beam is not thrown in the path of the presenter. The main advantages of these cards include a relatively low cost installation and close against the wall. The short projection projection system is an innovative system that can help change how the use of whiteboards.

    For an image to display, the touch surface must be calibrated first. The calibration process is to display a sequence of crosses or dots on the touch surface, and then selecting the points with a stylus. The calibration process can be eliminated with fixed installations such as when boards and projectors are bolted to the wall and roof, respectively.

    Some manufacturers have also developed another type of calibration that can detect the whiteboard projected images automatically. With this technology, the computer projects a sequence of black and white bars on the touchpad. sensitive light sensors at the rear of the origin of this surface to detect patterns of light allowing the computer to align the screen to the touchpad.
