There are two solutions to this that don't involve any new tech:
1) Don't move your POV in VR.
2) Train your brain interpret movement in VR as world movement not body movement. If you can maintain a sense that you're not actually moving just because your eyes are showing a lot of stuff moving around you, then your vestibular system and vision system will be in accordance and you won't have any motion sickness.
Children who use VR from a young age will have an easier time of this, but adults can learn it too.
