Nvidia Working On 4D VR Headset Which Eliminates Motion Sickness?

It seems Nvidia wants in on the virtual reality action, with sources saying it's working on its own VR device. The aim is to bring it to market by 2018, and its headset’s big selling point is that it’s aiming to totally eliminate motion sickness. That would be quite nice and a bit herculean, because none of the other VR players have managed to tackle this problem entirely, despite advances in the tech.

Nvidia’s creating the VR headset in conjunction with Stanford University, and it believes this is how the next generation of virtual reality is going to work. The headset uses a newly developed technology called Near Eye Light Field VR. This works by combining two 2D images, which they’ve coined 4D (2D + 2D), for each eye, merging to form a single 3D image. 
It’s believed to eliminate motion sickness. If it does indeed work in a similar fashion to the 3DS then it’s a very different sort of 3D to what you’ve experienced at the cinema. Rather than things coming out of the screen toward you, it’s more about depth and looking in. For the 3DS it can be like peering into a little box. This prevents you having to cross your eyes when objects seem near, which is one of the leading causes of motion sickness and headaches from prolonged use of VR.

“This is because of the vergence-accommodation conflict, which is how much the lens of your eye has to change to bring sharp focus to your retina,” said David Luebke, Nvidia’s senior director of research.

To get around this, Nvidia’s headset will use two LCD screens set five millimetres apart, sending two unique images to each eye. Appropriate use of these two screens that trick the eye into thinking objects are nearer or further away.
