The installation of the receivers can be segregated into the interior angle and exterior angle and can be fixed on the ordinary Whiteboards. If one wishes IWB could be installed to project Televisions and LCDs commonly known as projecting electronic Whiteboard.
The technology circles around Electromagnetic method, laser touch sensitive, infrared and ultrasonic. The upper surface of the board locates the laser resource. The Infrared technology requires a coiled or battery operated stylus which sends ultrasonic signs to the board. The touch sensitive boards can be used with fingers, pens, or markers.
One may choose from a range of models for the type of classrooms. Mainly two types of interactive whiteboards are obtainable. They are the hard boards and the Soft boards. A particular kind of pen is used on the hard plane of the board. The difference between the two is hard boards have a tough magnetic surface at the back of the screen, whereas soft boards have a hard layer on the surface. The touch of a finger or a particular pen is used to scribe on the board. Front projection model selection would be best for the classrooms and it may be fixed on the wall. The size of the board’s come in the sizes like 63″, 77″ and 82″.
If the classroom consists of a group of 10-15 students 63″ would be appropriate. Panels of Interactive Whiteboards are employed in a big classroom where more than 100 students assemble. In this technology users control the PC by means of a stylus or special pens on the LCD display and the PC image is visualized on the large screen. The same academic system becomes a digital classroom when Bluetooth and voting devices are added on.
