On April 3, 2014, the US Patent & Trademark Office published a patent application from Apple that reveals their work on next generation multitouch technology that uses FTIR (Frustrated Total Internal Reflection) and capacitive sensing. It's much like the technology that Microsoft calls PixelSense. It's a technology that could sense different pressure levels which could be used for an on-screen gaming controller. If you want speed, just push harder on the display and the car will accelerate. It may also be used for future virtual reality applications. With Apple's recent acquisition of PrimeSense, Apple definitely has something big that they're working on for 3D gaming and/or other advanced applications.
