An interactive whiteboard, or IWB for short, is a huge interactive display that hooks up to a computer and projector. The projector would display the computer's desktop onto the board, where the operator would control the computer using a device such as a pen or a finger. The board is generally mounted to a floor stand or to a wall. Their use extends to various settings such as church congregations, educational setups such as classrooms, corporate boardrooms and work groups, as a training instrument to large companies and an effective communication tool to broadcast studios, to name but a few. Its use extends to operating any operating system and software that has been loaded onto the PC connected to the interactive whiteboard, which includes web browsers. With various specific models of IWB, integrated audience response systems might accompany the whiteboards so that operators may interact with their audience by carrying out surveys and performing quizzes to receive responses on the whiteboard.
How an IWB is installed is that the device is connected to the operating system such as a computer, through a USB or serial cable or by means of a wireless connection such as Bluetooth. Software is then installed onto the attached pc where it effectively allows the interactive whiteboard to perform the duties of a Human Input Device (HID) like a computer mouse. An image would then be displayed onto the interactive whiteboard's surface from a digital projector that is connected to the main connected computer's video output. The whiteboard will then become active as soon as the driver starts running and at that point the user is able to adjust and attune the system, and if necessary, align the pointer with the image and set in motion programs, buttons and menus as they would with a computer mouse.
As for any text input that might be required, the operator can make use of handwriting recognition software or employ the utilization of an on screen keyboard. These solutions would avoid having the operator to return to the computer to have to enter texts. With the combination of mouse and keyboard utilization, the operator is able to be in charge of the computer's display almost solely from the interactive whiteboard. In an effort to maximize the audience interaction opportunities, most interactive whiteboards comes supplied with software that supplies tools and features purposely designed to add to the use of the interactive whiteboards. These uses in general consist of the capability to produce virtual version of paper flipcharts with pen and highlighting options, and in a number of cases even virtual tools such as rulers and protractors and compasses to imitate traditional classroom teaching equipment.
Interactive whiteboards may make use of a number of various sensing technologies to facilitate interaction on the white screen surface, such as resistive, infrared optical, electromagnetic, and ultra-sonic, laser and camera based optical technology. The most popular and commonly found whiteboard either makes use of resistive or electromagnetic operation. In short, there are numerous uses and benefits to interactive whiteboards. As its global popularity grows, the future expected market share of these products seems only to be on the rise.
