According to 9to5mac and Israeli publication Calcalist.co.il, Apple has purchased PrimeSense, the company that created the original Microsoft Kinect technology for $345 Million. This recent purchase will soon allow Apple to add controls that will require body movements. Similar to what has been seen on the Samsung Galaxy S4.
Apple has been working on its own gesture-controlled OS as seen below.
Microsoft used PrimeSense’s technology for the original Kinect. They have since replaced PrimeSense’s technology for their own in-house 3D mapping systems.
Here’s a video of their technology in use.
