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

Written by Jon Sutton on Mon, Nov 23, 2015 2:00 PM

It looks as if Nvidia wants in on the virtual reality action, with the news 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 a feat, 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 reckons 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. Now I’m no physicist but that doesn’t sound strictly like four dimensions. In fact, that sounds pretty much like how the Nintendo 3DS’ 3D feature works.

Whatever the case, it’s said 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.

If all goes to plan then Nvidia’s hoping we can get consumer versions of its headset from 2018.

My concern about VR has always been about health related issues particularly regarding those prone to seizures. I'm not prone to seizures but I'm probably never gonna use VR anyway mainly due to money.

You don't "need" to wear your glasses with a VR headset. They usually come with a set of lenses for people that need the correction that glasses provide.


That being said...glasses make reading text on a DK2 twice as easy, and that's not saying much

I'm there with you mate! I am unable to see with both eyes simultaneously + I need glasses on top of that. Seems like I'm just going to have to miss out on all this VR stuff. :/

I used the Oculus Rift once with my glasses, no problems.

As far as I know, most VR headsets including the Oculus allow for glasses.

Does that mean that things will not appear to move around you, but instead just be in a "box".
Regardless, I really think companies are over estimating how much the market wants VR Headsets. I certainly won't be buying one. I can't use my multi-monitor display with a VR headset. Or at least not to the same degree.
I suppose we'll see how they develop and grow.
