VR for mobile devices

General curiosity question. Is there currently any tools to create VR (or maybe I should call it AR?) games on a mobile device? If not is there any plans to do so?

Oculus Rift is plug and play as of now. For mobile devices the Note 4 with Gear VR will be supported and maybe Google Cardboard. AR is an entirely different problem. Getting good VR first is key then AR will come later. AR is actually harder to solve. Tracking the real world is difficult. Our brains are equivalent to 196.8 million processors. I’m not saying we need that much but for good AR. A phone needs to understand spacial relationships to the real world, and differentiate between objects. Not an easy task. There will be some hack crap but I’ll give it ten years before it’s a real usable thing.
