The Multi-Touch Collaboration Wall is a large (81 inch width x 48 inch height) monitor invented by Jeff Han that employs multi-touch technology, and is marketed by Han's company, Perceptive Pixel. Han initially developed the technology for military applications. The wall has received most of its publicity because of its use by news network CNN during its coverage of the 2008 US Presidential election. Usually operated by John King, it is often referred to as CNN's "Magic Wall",, though it is now more commonly referred to by on-air personalities as the "Magic Map."
Walls have been sold not only to CNN but to the US Military, as well as other government agencies Han has not named. The wall appeared in a catalog for upscale department store, Neiman Marcus.

Famous quotes containing the word wall:
“This is Wall Street, and today is important. Because tomorrow, July 4th, I intended to make my first million dollars—an exciting day in a man’s life. The enterprise was slightly illegal.”
