An interactive whiteboard or 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 or other device. The board is typically mounted to a wall or on a floor stand.As a cost effective alternative to big-sized LCD/LED/Plasma touch screens and displays, the IWB is used in a variety of settings such as in classrooms at all levels of education, in corporate board rooms and work groups, in training rooms for professional sports coaching, broadcasting studios and more.See this short video to learn how to use the interactive whiteboard for general presentations.
