I don't think you can solve that 100% with current mobile VR headsets, and any game that separates your in-game movement from your actual physical movement will cause some people to feel sick. I think developers are learning how to work with the hardware though, and things are getting much better. Plus the hardware itself is improving on that front too, for ex: http://www.theverge.com/2015/3/5/8153101/valve-boss-gabe-newell-says-noone-gets-sick-using-vive-vr http://www.theverge.com/2015/3/5/8153101/valve-boss-gabe-new... The Vive is quite a step up from the Oculus Rift DK2, and having played with it myself, that claim actually holds up pretty well.
