What will be the next generation VR?
4K? No. UHD only is enhacement of existing VR. The product existing in market focus on user head orientation. This is the first generation.
The next focus will be the human vision system. When we see, our eyeballs would point to object with different angle. Seen existing products provide the best visual in the center of screen. Any other angle of view would be strange. It is because the vision model is not able to handle this. I propose VR display require to add eyetracking modules for eyeballs movement compensation or view reconstruction.
