I think this is something that can be solved with more investment into electronics, alternative optics and display (e.g. Google-glass style display), as well as UX research.
I don’t see how. Motion sickness is a discrepancy between visual stimulus and signals from the vestibular system. If you show people motion and the don’t feel the motion, they will get motion sickness (to varying degree)
There are many VR applications that don't need to move the view separately from user input. Exercise programs for example, and a lot of office telepresence probably falls into this.
