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. Software then manipulates the information to triangulate the location of the marker or stylus. This technology allows whiteboards to be made of any material; with this system no dry-erase marker or stylus is needed. 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.

Portable interactive whiteboards (Indesign) are available for presentations on the move. You then connect the device to your laptop or desktop computer, make your notes or drawings on the whiteboard and download them onto your computer to save, print, fax or email them. You use tailor-made designed pens to write on the whiteboard that use infrared technology to determine where on the whiteboard you are writing. You can touch the board to control the computer mouse cursor. As you move the pen across the whiteboard, displaying the computer image, the mouse cursor follows. Portable Interactive Whiteboard works on almost any surface - an existing whiteboard, a flat wall, even a chalkboard with dry-erase paint, transforms those surface into an interactive whiteboard. No battery is required for USB signal receiver and the unit can be mounted to the ceiling if a permanent solution is required. Working with the extendable pointer E-Pen (Electronic pen) or stylus E-pen, you and your students can explore internet websites, build interactive flipcharts and create more opportunities for discussions and interaction in the classroom. Made of a tiny and lightweight material, the PIWB is easy to transport, even carried by children and ladies.
