I hear that. however I have also wondered though is how far do we go to compensate for simulation sickness? Something I do remember from my childhood is that people would sometimes get sick from playing Doom. Now granted it was few and far between because the game itself plays and starts pretty slow but me myself being a pretty hard core gamer at a young age could I could circle strafe pretty well and I could jet around levels rather quickly and accurately and this would often cause people watching to get sick from it.
It’s really an eye of the beholder thing and as mentioned in obe of the links you posted that the oculus team has tried many different combinations and all of them have inconclusive results it seems. For example: If my sister plays around with my Gear for about 20 minutes she needs to take a break but it appears that the more she uses it the easier it gets for her. And on the other end I have a friend in the Marines who has never seen VR before and swears he never gets motion sickness. True to his word he played with it for about an hour walking around jumping and ducking with no effect what so ever. The way he was moving about I swear I thought he was going to randomly vomit but he went ham on the thing till my phone started overheating.
Me personally I am rarely effected by it except for this one time in Arma2Dayz when I had one of those tiny gyrochoppers and I was barrelrollin into a forrest. These things make me think about the method in which your game is being played as I felt absolutely fine for a couple hours in until that heli crash.
Perhaps a good babystep to take as a precaution is if you are doing something with alot of movement to have a sort of “warm up” to prepare your body for what you might see as opposed to just unleashing the beast on someome. Honestly I just don’t really know what to do about the whole simsickness as it just seems so opened ended.
