Patently Apple:

Last week Patently Apple posted a report titled “Apple invents a 3D Depth Mapping Camera for Hand Gesturing Interfaces for Future Macs & Smartglasses.” It’s a recurring theme (one, two and three) from Apple’s PrimeSense team from Israel. Today another such patent filing has surfaced titled “Gesture based User Interface,” based on hand gestures.

There’s more detail in the post and, of course, in the patents themselves. But in a nutshell, 3D mapping cameras and a host of hand gestures are likely in Apple’s future, along with tracking software for your Mac, Apple TV, and Apple Glasses.
