|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 digitalpen, finger or other device. |
The board is typically mounted to a wall or on a floor stand. They are 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 professionals and more. (Source: wikipedia)

Multi-point Interactive Whiteboards Using the Wiimote
The Wiimote (Wii Remote Controller) can track sources of infrared (IR) light, and can therefore track pens that have an IR led in the tip. By pointing a wiimote at a projection screen or LCD display, you can create very low-cost interactive whiteboards or tablet displays. Since the Wiimote can track up to 4 points, up to 4 pens can be used. It also works great with rear-projected displays.
