Intel wants to put its RealSense 3D cameras into smartphones and CEO Brian Krzanich showed this slimmed down version in Shenzhen, China. The 6-inch prototype is about half the size of the older version and the company wants to deploy the technology this year. The RealSense 3D cameras can sense depth much like a Microsoft Kinect sensor. That means you could control applications on your phone with gestures or take a 3D scan of an object among other things. Intel has been wanting to bring RealSense to PCs and tablets, but the smaller size opens up the option for smartphones too. That gives Intel another opportunity to break into mobile, which has been dominated by ARM based chips from rivals Qualcomm and MediaTek. Intel talked up the technology in at its developer conference in Shenzhen, which is a major manufacturing base in the country and home to tablet and smartphone vendors with lesser known names.
