For me not much happened at first but after a while I started noticing Judder in real life, lol.
I have this same "feeling/experiance" I keep getting visual "slip" like when the headset looses tracking for a moment. I even "see" it in bed with my eyes closed!!
Very odd, but also entertaining lol
I never had it prior to getting my Rift.
Right? .. yea it used to happen especially whenever something moved past me .. like standing on the sidewalk and a car flew by .. something about the detection of "sudden movement" triggered a visual response similar to the judder/skip you experience in VR sometimes.
Havent seen it in a year though ... was definitely a trip.
We have had this issue since the 1960's when the first dedicated visual flight simulators came into effect on wide-scale adoption. Those back then used "model boards" but still game enough of a immersive effect that pilots would report "phasing" (the person feels as if they are still taking part in the simulation even in real life). This was best illustrated by the number of RTA's that took place on base that were blamed on "phasing".
Back in 1996 we worked on a VR project that also had the same problem, people felt they were still in the sim after finishing. It was weird as I experienced it myself. That slight feeling of disconnectedness. Jump forward to recently and I had "phasing" again - this time though it was slightly different. It was associated with the latest PC Backpack VR experiences.
I think this is always going to be with us - the tech equivalent to "sea-legs".
