How 3-D Gestures Work


Author's Note

I got the idea for this article after my visit to CES 2012. It seems like there's a new emerging trend at the show every year. In 2012, that trend was the reinvention of the user interface. It seemed like every company was trying to add in gesture and voice control systems into products. But don't get too excited -- it might take a year or two for those innovations to make their way into common consumer electronics.
