I believe (as a layman) that motion sickness in vehicles is caused by a mismatch between what the vestibular system perceives and what the eyes do. However, headset-based VR systems have an additional issue called vergence-accommodation conflict, which is where the focus of each individual eye isn't at the same distance as the stereoscopic vision of both eyes together. My prediction is that one day (in twenty years, perhaps) we'll have miniature holograms for displays and thus get a proper match between accommodation and vergence! https://en.wikipedia.org/wiki/Vergence-accommodation_conflict https://en.wikipedia.org/wiki/Vergence-accommodation_conflic...
