Our lab is for gait studies, subjects typically walk back and forth on a 9 meter walkway which renders the position tracker that came with the oculus useless. Not being able to get around the yaw-drift, which I agree can't be corrected, I attached a cluster of markers to the hmd and use the marker data to update the orientation of the view in "live mode". It's not as nice as the 1000 Hz gryo, I use a kalman filter to try and reduce the jitters but at least there is no yaw drift. I suppose if I felt outgoing I could continue to use the gryos and use the marker data to correct the yaw once in a while.
