Forget relying solely on touch to control your Apple device. On future iPads, you may be able to control your tablet from across the room using 3D gestures, such as a swirl or swipe of the hand.
As suggested by a newly uncovered Apple patent, you would be able to manipulate and control graphical elements on your display, such as icons, media files, text and images. The gestures themselves could take many forms: geometric shapes (e.g., a half-circle or square), symbols (like a check mark or question mark), the letters of the alphabet, and other sorts of predetermined patterns.
