NVGs and VR

[fulcrum_64th]

Dear All,

 

First happy new year to all of you! After a long brake I started again flying DCS! I do 100% of my flying using my oculus rift. Quite a bit of optimisation since I last used it! Me happy camper :lol:

Thanks DCS! Looking forward up the upcoming optimisations and more F/A-18 features!

But now to my question: the night cockpit is superb and the NVGs are correctly focused at infinity and the cockpit therefor looks blurry: in reality the pilot use the peripheral vision to look at the instrument. But with my VR googles (110 deg FOV) the entire FOV is NVGs. is there a way to reduce the NVG FOV?

 

Again thanks for your help.

 

Best

 

Karim

well, I think you'r entire FOV being NVG makes more sense anyway, given that the VR FOV is closer to the NVG FOV than to your real life eyes FOV...

The FOV for standard binocular NVGs is only 40 degrees.

 

4 tube panoramic NVG expand this to around 90, but are only in use by a very small subset of the community. The rest of us fly behind binocular NVG.

The Strike Eagle community fielded them for a bit, saw quite a few crews come back with busted nose bridges. Think word spread and most abandoned them. They dont seem to react to well to Gs.

Didn’t know that! But it makes perfect sense,

 

I am hoping we will get them in the helicopter community, peripheral vision is so important for us. The weight will still be an issue though...

You think wrong, sir. Besides RL NVG’s having a much narrower FOV than VR headsets, the FOV number still only refers to horizontal FOV, an imaginary line running horizontally across the center of your vision. Irl you can easily ‘look under’ even the wide angle four tube NVG’s.

To answer the original question, yes DCS renders the NVG view incorrectly in VR and there isn’t a setting or workaround currently available to correct it.

That RL view would be a great implementation for VR

Yes that's the point. The oculus fov seems close to the binocular fov, to me at least

You are right. I didn't think of the vertical fov.

 

And nope, my binocular Mum-14 setup isn't much narrower than my oculus rift fov on the horizontal

Not really... Rift spec says 110 degree FOV. For NVG, I think it’s 40 per eye, but due to overlap I don’t think that equates to 80 degrees.

 

From a subjective point of view, with hundreds of hours flying helicopters on NVG, I can tell you the rift FOV is significantly more than NVGs.

+1. We have been requesting a reduction to the NVG field of view so we can see under NVG's to view all the rest of the instruments and the radar as is done in real life.

I'm gonna throw out something I've wanted to see (and poseted several times about) for a while now, which is the option to choose which eye(s) the BVGs would apply to.

There was an update a while back that made the a-10's NVG only appear in one eye a while back, and I was really disappointed when they changed it.

 

That would be a great way to solve this problem, as your dark adjusted eye can read the instruments as normal, while the NVG adjusted eye can see outside. I'm fairly certain that is/was how it's done IRL.

[WindyTX]

Hmm but I kinda need both eyes to fly close formation.

While I'm not one to say 'more options = bad', I'm also not aware of NV ever being done single-eye in aviation. Maybe it was tested (I mean, everything has been tested), possibly even operationally, but I've never come across something like that. To me that would be a recipe for instant disorientation.

Are you sure you're not thinking of the single tube NVG's that fed both eyes? Those might've been used by transport/bomber crews before, a loooong time ago.

I get your point. I never felt my oculus gave me 110 fov but maybe I'm wrong

Of the conditions doesn't make close formation flying safe, why to do so?

 

Safety first....

The VR manufacturers cheat, they give combined FOV as one. In reality you get closer to 60 degree. Test it, extend your arms when you see both and then measure width and range of the area you see on wall to you.

 

When we get true 100-110 degree FOV, it will be more than enough for most purposes.

ok.. then thats why I feel like my oculus FOV pretty much matches my dual mum-14 NVG setup.

Sorry but we used to practice close formation on the Squadron with our dual tube NVGs as fundamental skill. It was in no way dangerous or even particularly difficult.
