Infrared interactive whiteboard (Indesign IR 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 floor stand. About the IR technology for the IWB, when pressed to the whiteboard surface, the finger or marker sees the infrared light.

The IR IWB is 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 more.
