HP Wall of Touch!

Imagine a LARGE interactive display that doesn't even have to be touched for it to respond! That's what HP is testing - a touchless "Wall of Touch". It's made up of nine 43" "zero bezel" displays, each 1.5" thick with a resolution of 1080p, being driven by HP Z-800 workstation. Can you imagine walking by being able to find a store, or see different video feeds with a flick of movement? Check out the WSJ blog posting and video demonstration, and see it for yourself.
