Thank you Jannik!
Not overtly. At the moment I would just suggest playing only while it is comfortable. As soon as you feel any sickness the headset should be taken off and you should take some time to recover. With more time in VR resilience to sickness increases but I would always suggest caution and going easy. Its too fun not to play but you dont wont to ruin VR by conditioning your body to expect sickness. Also don't drink and play.. That should go without saying but .. you never know.
As eye focus tracking becomes more widespread there would be room to implement 'special tricks' for motion sickness.
Thanks for bringing this point up. I forget how 'sickness' inducing VR can be at the beginning.. and for those who just have good depth perception.
