Last week the US Patent & Trademark Office published a patent application from Samsung that reveals a possible 3D GUI for future smartphones. This idea has been around for some time now. As our cover graphic illustrates, Apple filed a patent application for this pertaining to an iPhone back in 2012. Apple's work on a 3D GUI for the desktop dates back earlier than 2009. In that same year an App showcasing this 3D effect emerged and you could see it in a video in our report below. The original design came from Jonny Chung Lee who first introduced this unique form of glasses-free 3D interface back in 2007.
