The HP touch wall isn’t something that you will see in your house anytime soon but it’s still really cool to see. It’s like a giant touchsmart computer. The WSJ had the chance to see it in action. While this screen is call the “wall of touch” you don’t have to touch it for it to work. They are testing touchless technology to control the screen. It uses cameras and magnets to trigger touch before the touch. I would have a hard time not touching the screen. I still need the feel of touch. Maybe they will come out with gloves that make my fingers feel like they touched a screen I’m not suposed to touch. Still very cool.
