We currently use the Oculus Rift in the motion capture lab that I run in Philadelphia. Sending a display to the Rift is easy. You just need to set up the Rift as a display device on the PC running Jack. Set the display resolution to 1280x800. Then set up a left eye and right eye view for a floating head or full avatar on respective sides of this display screen. If you rotate the eye sights out by 6 degrees on each eye, you get a nicely merged image inside of the Rift.
We have not yet integrated with the inertial head trackers, as we generally use an optical motion tracking system.
Thanks for your reply, it really helps to know that you already developped that solution! We should have the last DK2 at the end of August, 2014, so I will let you know after this date. We also have an optical mocap system so we will use it to parameterize the point of view adaptation.
Thanks again for your help,
