Interactive whiteboard

 Interactive whiteboard at CeBIT 2007

An interactive whiteboard (IWB), is a large interactive display that connects to a computer and projector. 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.

Uses for interactive whiteboards may include:

• Running software that is loaded onto the connected PC, such as a web browsers or proprietary 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
• Online whiteboard^[5]
• 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 feedback onto the whiteboard
