Can VR be used with only one eye

[wildbill6641]

I have only ONE eye! Can I have a useable and satisfactory vr rig???? I presently have a hi end lt and 37" curved moniter and trk5. I can afford to spend some money BUT NOT for some thing thats not going to work! A reply from some one using with one eye would be much appreciated!

I have booth eyes, but I know much about vr goggles. You can use them, similar as in real life, if you have only one healthy eye, you see with it only. 

What is different? Fov (field of view), or angle of how much space you see in front of you - with two healthy eyes usually you have higher fov "combined".

 

Long story short, yes, you can use it. Fov will be some smaller. Also be prepared that your picture will not be strait in front of you, it will be more shifted to your eye side, and you will see less to your nose. That will be more visible with canted displays (Pimax), and less with strait displays (i.e. Reverb G2). 

 

If you can wait a little, then order G2 and see. If not ok, you can send it back.

Hi wildbill!

I went on  to check it out for you, first with only left eye and then with only right one and it's definitely possible with some minor downsides such as reduced field of view by ~10-15% when using only one eye and i had a bit motion sickness but it may be due i'm not used to fly with only one eye, also same as rest of us you'll need to adjust gunsight view (move your head to desired position and press f10 to save view as default).....other than that i found it quite good and bareable experience even i'm not used to it!

NOTICE> i did test on Oculus Rift S which uses single LCD display for both eyes so i don't know how it'll work with VR headsets that use 2xdisplays (one per eye) such as Reverb G

Your PC will have to calculate and render two screens instead of one, which drastically reduces your performance.

 

You need to take that into account that you may have to upgrade your CPU/MB/Graphics card and still have a picture of less quality than on your screen. Just so you know.

 

Also, don't get any headset. You would rely heavily on being able to rotate your one eye around and have clear vision, and many headsets do not have Fresnel lenses that are up to that task.

 

You could tell us what your PC hardware is, and we'll help you if you need to upgrade and to find a proper headset (my Reverb G2 is coming this week or very shortly afterwards).

 

Then you can estimate better if the price is worth the risk to you.

VR with one eye is kind of cumbersome. 3d effect comes from using two eyes, and even then, not everyone with two working eyes sees in 3d, you actually have to learn it, and that doesn't happen naturally to all kids, especially if they have poor eye sight diagnosed late. Of course, you will have a sort of head tracking device effect, perhaps better in some ways, perhaps worse. Probably not worth the cost, I imagine.

 

Sorry to be so blunt, I mean it in the friendliest of ways. I'd be happy to have a better sight too. Didn't start with such a good one, and getting old, I guess.

Maybe buy a headset from a place that has a good return policy, and if it's not worth it, return it. VR will work and you'll get a sense of 'presence' in the airplane, but VR is already much less competitive than flat-screen + TiR.    VR without the depth perception might not be worth it.

[firdimigdi]

Now that's a tough one. My advice as well would be to try-before-you-buy, see if maybe a friend or a store nearby has a headset, any headset, you can try. It's not so much that you can't use it as the illusion of being 'in the gameworld' will be much the same. As I understand it it, any hindrances you have IRL will also translate in VR as well.

 

A quick google search shows that there's been enough interest in the subject: https://www.google.com/search?q=vr+with+one+eye

It's a shame you can't disable one eye in the headset to save come computational power.

Without both eyes VR is rather a pointless exercise. 

You can use it by all means but you miss out on the biggest benefit - 3D Depth Perception.  You would though benefit from 1 to 1 world scale in sim with a VR headset but at performance costs over a single monitor.

 

As mentioned, pity you can't disable one side of the render pipeline for a VR headset so you wouldn't have to bother with rendering for your non eye if you go down the VR path.

 

There is also proper tracking unlike with TrackIR but with your 37" Monitor, may as well stick with that.

I happen to be blind in one eye and I love playing in VR.  Basically I see the same as I do in the real world.  I was worried at first because I can't watch 3d movies (the old kind with the blue and red lensed glasses) but VR works great for me.  I'm currently playing IL2  with Oculus Quest 2 using Virtual Desktop and it works great, especially once you get into it.  

 

If your like me, I've been blind in one eye since birth, our brains are trained to see with only one eye.  I can see some light and shape in my "blind" eye but my brain just kind of tunes it out.  I'm in my 40's and the doctors say that even if they were able to correct my vision in that eye that my brain may not accept it because it would have to relearn how to see.  So whenever I put on the headset, the same thing happens.  It looks normal to me.  

 

I hope that helps and have fun if you get the chance, VR is a game changer.

One eye would work fine.  Go for it.  Yah that would be cool if someone made you something so that you don't have to have your PC render the blind eye screen.

[SCG_Fenris_Wolf]

That's right. People lost a leg, and still enjoy walking as much as they can. Go for it, why the hell not 

 

Remember to post hardware and what headset to go for, we'll help you out.

 

Chiliwili has just posted a nice thread about hardware choices

[Beazil]

I'm reading this thread with interest.  I would have never thought a person with one eye could perceive depth.  A person with two eyes could obviously compensate depending on the severity of the vision impairment, but with one eye to me this shouldn't work.

As a professional who's job it is to work with people with disabilities, and as a VR flight sim enthusiast, this is a gold mine of a discussion.  Thank you all!

 

Bill, just for curiosity's sake, tell me a bit about the difference between your flat screen experience vs the curved monitor you use now?  Have you tried any other method of 3d or VR before?  Does something like Google cardboard work for you?  It's a cheaper way to find out if VR is worth the price tag if you have an Android phone.... Just thinking out loud here.

You know, I wonder if you could get better mileage using one of the cellphone adapters and setting it up for monocular vision? The head tracking would be the main thing one would gain from it, and with only a single screen to drive, I'd think you could drive that one screen up to 4k+ resolution with far less effort. 

 

Basically the human eye hands about 60-120 pixels per degree, and even the Reverb only gets to 20 pixels per degree. 

 

Maybe use something like a modified Google Cardboard, combined with one of the camera face tracking tools?

Hi there, Bill

 

i have the same problem as you, one eye only and been thinking about getting the VR. But first gotta try it out. I’m not concerned about the depth perception but about putting my head in the cockpit. I was thinking whether with some headsets it is possible to switch off the right screen/eye and use only the one I got:) that could potentially increase performance. What makes me interested is the 1:1 movement speed of pilots head compared to the acceleration of track it. 
Also, do you guys know whether the normal zoom buttons work in VR should thee be need to e.g. zoom to some ground object or so?

 

im getting in touch with a couple of venues here in Warsaw to try out their headsets but gotta know which ones to try as they charge a lot for a lease…

 

once I know I can use it with benefit for my flying experience I’m gonna maybe get it for my 40th birthday. No other games than flights sims are of my interest in vr department. Maybe dcs ans Il2 would be the only ones.

 

cheers and love your eyes, folks :)

I'm one eyed (temporarily!) since yesterday. What I noticed was that the G2 is incredibly reducing FOV off one eye, noticeably harder than as if you'd use two.

 

It may be very interesting for you to get a VR headset that has a larger FOV. 

Much of your vision is just in one port so you want to maximise that, the average/tinier FOV headsets like quest 2 or reverb g2 may not be your first choice, as they lose up to half the space of each eye.

 

In 6 hours ViveCon starts and new headsets will get presented, among them the Vive Focus 3 which will be wider FOV close to pimax-style. 

Head over to Vive.com and register quickly, you'll need an access key.

[=FI=Macca]

Thank you!

 

I couldnt attend the vive.com, but will keep my eye (!) on these new headsets. 

 

In the meanwhile gotta lease one similar for 24 hours and see how it works.

 

Thank you for the information about FOV, wasnt aware of that, its something to pay attention to.

 

Cheers!

The Vive Pro 2 is announced with a 120° horizontal FOV (~140-145° diagonally), which is only beaten by Pimaxes (in medium FOV mode) currently, while the Reverb G2 is just 114° diagonally and the Quest 2 110° diagonally. . But together with two Basestations you'll sit at $1000 entry price for the VP2 (no controllers yet), and just $600 for the G2, or $800 for the Q2 (business edition, I'd never get the see my living room and wife's panties-version).

 

I just flew today for half an hour with one eye under the patch (it'll take a few more days of healing), and it was fine. Yes, I lack the depth perception now just like irl as blitze said, but my brain isn't trained for one eye. I've read that one eyed don't use spatial offset for depth perception but more of the surface and texture information to define distance, similar to people who need to use glasses (they also lack depth perception, you need to be at least half a year radically off glasses to regain spatial perception). So it's no big deal, if you're fine with the G2 or Q2 by all means, go for it and focus on keeping the resolution up as much as possible.

 

If you can order the G2/VP2 from a place in which you keep a right to return, then shoot, maybe you'll enjoy it. It has to beat your monitor (which has no disadvantage as it doesn't carry any spatial depth either).
