In new apps, hand gestures control the action

A collection of new apps let users zoom, pan and control the action using hand gestures instead of traditional keyboards or mice.
Like waving a wand, new apps are bringing a bit of magic to computers, enabling users to zoom, pan and control the action with hand gestures.

A new app store called Airspace, launched by San Francisco-based company Leap Motion last week, has 75 apps that are all controlled with the wave of the hand.
"Right now in front of your computer, there's dead space. You're only using your desktop, where your keyboard and mouse rest, and the surface of your monitor," said Michael Zagorsek, vice president of product marketing for Leap Motion.
"We take all that otherwise useless space in between and make it come alive," he added.
