According to Epson, this projector integrates interactive functionality in one machine without the constraints or expense of an interactive whiteboard. The 450Wi can project images up to 96-inch in native WXGA, uses an ultra-short throw projector design that claims to eliminate many of the common problems of interactive systems such as an intrusive classroom footprint as well as eye glare, and has a new mount designed for simple wall installations.

"Anchored close to the wall, you can project extra-large, 80" images from just 2' away," says the company.

In addition, the projector works on almost any surface "an existing whiteboard, a flat wall, even a chalkboard with dry-erase paint. Interactive capabilities are built into the projector and not into a board, so virtually any surface will work". 

Finally, its interactive pen works like a mouse on your PC/Mac. "It is software agnostic and Web 2.0 friendly. Similar to a computer monitor, the open architecture allows users to use, share, and engage with virtually any software, digital media file or e-textbook," concluded the company.
