To understand clearly how the interactive white boards could be capable of increase the teaching environment, you’ll want to fully grasp the sensing technologies that are employed to track the interaction on the screen surface. They are resistive, laser, infrared optical, camera primarily based optical and ultra sonic. Among all these technologies, by far the most prosperous in commercial interactive whiteboards use electromagnetic and resistive technologies.

The resistive touch screens are produced up of two versatile sheets every with a coat of resistive material and separated by a layer of micro thin air space. In operation the two screens press with each other, therefore registering the precise place where the screen was touched. With this technologies one particular can use a finger, stylus or any other pointing device. With all the electromagnetic technology the board features an array of wires embedded under the board surface. These interact with the stylus tip to provide the precise place working with the X and Y coordinates.
The type of stylus varies. You may use an active stylus which uses battery power or which is wired for the white board. There are also passive styli which depend on electrical signals developed by the white board therefore requiring no external source of energy. In simple terms the electromagnetic white board can be described as obtaining magnetic sensors which react and send messages for the laptop when the board is activated by use of a magnetic pen.
Aside from the two big technologies, the other technologies are also gaining momentum within the interactive white board market and for that reason should not be ignored. Together with the optical infrared technologies, you might want to press the board surface for the infrared light to become visible. This enables the support software program to triangulate the location of the stylus or marker. With this technologies, the whiteboard might be made from any material.
The laser interactive whiteboard technologies uses an infrared laser situated inside the upper corners of your whiteboard. The laser beams operate by sweeping across the surface on the whiteboard employing rotating mirrors. The marker or stylus made use of to create on the board reflects the laser beams back to the supply therefore enabling the triangulation from the X and Y coordinates. This technology works well using a really hard surface such are steel or ceramic which also possess the advantage of simple cleaning.
With ultrasonic and infrared, the stylus sends out an ultrasonic sound at the same time as infrared light when pressed on the board surface. The board has two ultrasonic microphones that acquire the sound and calculate the differences in arrival time. This aids within the triangulation of X and Y coordinates. This technologies also allows the whiteboard to be made from any material. On the other hand, a suitable adapted stylus or active dry-eraser marker is vital.
Apart from these technologies there are actually also other significantly less significant technologies for example frustrated internal reflection, ultrasonic only and Wii Remote IWB. Though interactive whiteboards are technologically sophisticated, there are actually certain problems which are typical with most varieties. For instance working with permanent markers on the whiteboards may cause problems. An additional typical situation could be the threat of dents, punctures along with other damages towards the surface which are not experienced with standard boards.
