Interactive whiteboard

An interactive whiteboard (IWB), is a large interactive display that connects to a computer. A projector projects the computer's desktop onto the board's surface where users control the computer using a pen, finger, stylus, or other device. The board is typically mounted to a wall or floor stand.

They are used in a variety of settings, including classrooms at all levels of education, in corporate board rooms and work groups, in training rooms for professional sports coaching, in broadcasting studios, and others.

The interactive whiteboard industry was expected to reach sales of US$1 billion worldwide by 2008; one of every seven classrooms in the world was expected to feature an interactive whiteboard by 2011 according to market research by Futuresource Consulting.^[1] In 2004, 26% of British primary classrooms had interactive whiteboards.^[2] The Becta Harnessing Technology Schools Survey 2007 indicated that 98% of secondary and 100% of primary schools had IWBs.^[3] By 2008 the average numbers of interactive whiteboards rose in both primary schools (18 compared with just over six in 2005, and eight in the 2007 survey) and secondary schools (38, compared with 18 in 2005 and 22 in 2007).^[4]

Uses for interactive whiteboards may include:

• Running software that is loaded onto the connected PC, such as a web browsers or other software used in the classroom.
• Capturing and saving notes written on a whiteboard to the connected PC
• Capturing notes written on a graphics tablet connected to the whiteboard
• Controlling the PC from the white board using click and drag, markup which annotates a program or presentation
• Using OCR software to translate cursive writing on a graphics tablet into text
• Using an Audience Response System so that presenters can poll a classroom audience or conduct quizzes, capturing

  Operation of an electromagnetic pen-based interactive whiteboard[edit source | editbeta]

  An electromagnetic pen-based interactive whiteboard involves an array of wires embedded behind the solid board surface that interacts with a coil in the stylus tip to determine the horizontal and vertical coordinates of the stylus. The pen itself usually is passive, i.e., it contains no batteries or other power source; it alters the electrical signals produced by the board. For instance, when close to the surface of the board, the mouse pointer can be sensed, giving the board "mouse-over" capabilities. When it is pressed in against the board in one way, the board activates a switch in the pen to signal a mouse click to the computer; pressed in another way, contact with the board signals a click of the right mouse-button. Like a scaled-up version of a graphics tablet used by professional digital artists and designers, an electromagnetic IWB can emulate mouse actions accurately, will not malfunction if a user leans on the board, and can potentially handle multiple inputs
