To understand clearly how the interactive white boards could possibly have the ability to boost the teaching atmosphere, you'll want to recognize the sensing technologies that are utilized to track the interaction on the screen surface. These are resistive, laser, infrared optical, camera primarily based optical and ultra sonic. Amongst all these technologies, probably the most profitable in industrial interactive whiteboards use electromagnetic and resistive technology.

The resistive touch screens are made up of two flexible sheets each with a coat of resistive material and separated by a layer of micro thin air space. In operation the two screens press collectively, hence registering the precise location where the screen was touched. With this technology one particular can use a finger, stylus or any other pointing device. Using the electromagnetic technology the board features an array of wires embedded below the board surface. These interact together with the stylus tip to offer the exact location using the X and Y coordinates.

The type of stylus varies. You can use an active stylus which makes use of battery energy or which is wired towards the white board. You will discover also passive styli which depend on electrical signals produced by the white board therefore requiring no external source of energy. In easy terms the electromagnetic white board could be described as getting magnetic sensors which react and send messages towards the laptop or computer when the board is activated by use of a magnetic pen.

Apart from the two important technologies, the other technologies are also gaining momentum in the interactive white board industry and for that reason should not be ignored. With all the optical infrared technologies, you must press the board surface for the infrared light to be visible. This permits the support application to triangulate the location with the stylus or marker. With this technologies, the whiteboard is usually created from any material.

The laser interactive whiteboard technologies uses an infrared laser located within the upper corners from the whiteboard. The laser beams operate by sweeping across the surface of your whiteboard using rotating mirrors. The marker or stylus utilised to create on the board reflects the laser beams back for the source hence enabling the triangulation from the X and Y coordinates. This technologies functions properly having a challenging surface such are steel or ceramic which also possess the benefit of uncomplicated cleaning.

With ultrasonic and infrared, the stylus sends out an ultrasonic sound at the same time as infrared light when pressed around the board surface. The board has two ultrasonic microphones that obtain the sound and calculate the differences in arrival time. This assists within the triangulation of X and Y coordinates. This technologies also permits the whiteboard to become made from any material. Nonetheless, a suitable adapted stylus or active dry-eraser marker is necessary.

Aside from these technologies you will find also other less considerable technologies such as frustrated internal reflection, ultrasonic only and Wii Remote IWB. Although interactive whiteboards are technologically advanced, you will discover certain concerns which are popular with most kinds. For example making use of permanent markers around the whiteboards can cause issues. Another prevalent issue could be the threat of dents, punctures as well as other damages towards the surface which are not knowledgeable with typical boards.
