Quince Farber

I'm curious about the oculus development. I know there was the 'Stereosopic viewer patch from the univeristy of michigan." Was this used as the foundation for Rift Development? if so has it progressed past the orginal patch? if so in what ways? I just ask because i'm curious if there been any progress in modifying FOV, and adding distortion to modify the image to 'wrap' with the diffrent types of oculus lenses, using the oculus rift input for mouse look,. predictive rendering, and any thing else that may need to be done to keep the frame rate up.
