OSVR - An Open Source standard for Virtual Reality

Hardware developer Razer trying to establish an open standard for VR applications

This looks like a promising path for preventing incompatible hard- and software and push the potential of the VR market to a new level in 2016/2017.
Razer partnered with a couple of big and innovative players of the industry: Intel, Ubisoft, Leap Motion, to name a few. 

2016 will be an exiting year for VR application!

Update: There is already a young and early OSVR support by Epic's Unreal Engine, one of THE VR compatible engines - a good sign!
