Technologies Utilized in Interactive Whiteboards

To know clearly how the interactive white boards may well be able to increase the teaching atmosphere, you have to realize the sensing technologies that are used to track the interaction on the screen surface. These are resistive, laser, infrared optical, camera primarily based optical and ultra sonic. Among all these technologies, essentially the most productive in commercial interactive whiteboards use electromagnetic and resistive technologies.

The resistive touch screens are produced up of two flexible sheets every single 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 exact place exactly where the screen was touched. With this technology 1 can use a finger, stylus or any other pointing device. Using the electromagnetic technology the board functions an array of wires embedded beneath the board surface. These interact with all the stylus tip to offer the exact location utilizing the X and Y coordinates.

The type of stylus varies. It is possible to use an active stylus which utilizes battery energy or which can be wired to the white board. There are also passive styli which depend on electrical signals made by the white board hence requiring no external supply of power. In straightforward terms the electromagnetic white board may be described as obtaining magnetic sensors which react and send messages towards the computer when the board is activated by use of a magnetic pen.

Aside from the two major technologies, the other technologies are also gaining momentum in the interactive white board market and for that reason shouldn't be ignored. With the optical infrared technologies, you'll want to press the board surface for the infrared light to be visible. This allows the assistance software to triangulate the place of the stylus or marker. With this technology, the whiteboard might be made from any material.

The laser interactive whiteboard technologies makes use of an infrared laser situated within the upper corners in the whiteboard. The laser beams operate by sweeping across the surface on the whiteboard working with rotating mirrors. The marker or stylus applied to write around the board reflects the laser beams back for the supply hence enabling the triangulation from the X and Y coordinates. This technology operates nicely having a hard surface such are steel or ceramic which also possess the advantage of easy cleaning.

With ultrasonic and infrared, the stylus sends out an ultrasonic sound as well as infrared light when pressed around the board surface. The board has two ultrasonic microphones that obtain the sound and calculate the variations in arrival time. This aids inside the triangulation of X and Y coordinates. This technologies also makes it possible for the whiteboard to be produced from any material. Even so, a suitable adapted stylus or active dry-eraser marker is vital.

Aside from these technologies there are also other much less substantial technologies which include frustrated internal reflection, ultrasonic only and Wii Remote IWB. Despite the fact that interactive whiteboards are technologically advanced, you will find certain challenges that are frequent with most kinds. For instance employing permanent markers on the whiteboards may cause challenges. Yet another popular concern may be the threat of dents, punctures along with other damages for the surface which are not seasoned with standard boards.
