Education Projectors Buyer's Guide
It’s only when used as an interactive whiteboard that its true potential is displayed. A projector projects the computer’s desktop onto the whiteboard allowing an instructor to control an application program using a pen, finger or similar device instead of typing on a keyboard or clicking a mouse. Information displayed on the whiteboard can be captured and saved for later use.
The board is typically mounted to a wall or on a floor stand. The screen can be used to display not only computer software to a class, but with the proper connections, web pages and videos, whether on DVD, VHS or CD-ROM. Potentially, this setup could replace the standard classroom overhead projector, video recorder and television.
