INTERACTIVE WHITEBOARDS<br />

board mouse like capabilities. An Electromagnetic IWB can potentially<br />

handle multiple inputs. ACTIVboard, Communicator, Focus<br />

Board, Slimboard, Interwrite, HDbord, Penbord are all vendors that<br />

market electromagnetic whiteboards.<br />

• Interactive projectors<br />

An interactive projector has a camera built into the projector. The<br />

projector produces the user interface and detects the position of an<br />

active IR light pen when it contacts the surface of the board. This<br />

solution, developed in 2007 and patented in 2010 by U.S. manufacturer<br />

Boxlight, is a new highly interesting technology. Next to<br />

Boxlight, Hitachi has also recently developed a new kind of board<br />

that combines a whiteboard and an image sensor.<br />

• Touch screens<br />

Touch screens are like giant Ipads. When large size LCD screens<br />

become affordable, this technology may very well be the successor<br />

of the interactive whiteboards as we know them today.<br />

Well known vendors are: Bordwijs, Focus Touch, Legamaster<br />

e-Screen FLEX, NEC lcd Touch, Starscreen Touch and Samsung<br />

‘clickers’ operating via Infrared or radio signals offer basic multiple<br />

choice and polling options. More sophisticated clickers offer text<br />

and numeric responses and can export an analysis of student performance<br />

for subsequent review.<br />

By combining classroom response with an interactive whiteboard<br />

system, teachers can present material and receive feedback from<br />

students in order to direct instruction more effectively or else to carry<br />
