PrimeSense's Captri chip (shown here next to a pencil for size) is ready for use in tablets, mobile phones, and other consumer electronics.

Apple has purchased PrimeSense—a company that specializes in 3D sensors. The $345 million deal will give Apple access to the motion sensing technology that was the biggest selling point of Microsoft's Xbox 360 Kinect.

Analysts are predicting that Apple will use the technology in everything from smartphones to Apple TV. Others are wondering if this is an example of Apple buying up technology so that its competitors can no longer use it. (Venture Beat notes that Apple already has its own 3D imaging patents.)

PrimeSense has a pretty good idea of what its ideal 3D tech-using world will look like. Check out the world's cheesiest promotional video about 3D technology below:

If Apple does decide to use some 3D sensors in its next tablet or smartphone, how would it be done? Would it have a front-facing sensor for touchless interaction like the Samsung Galaxy S4? Or could Apple incorporate the technology into its rear-facing camera to help users take better photos?
