Idea of improvment.

Re: cocky, I cannot begin to compete with your reputation at other websites in that department. :o At least I provide valuable and useful information to go with my attitude, so perhaps it is justified. I trust my own judgement.

I have to admit that after reading your posts (and KBKs post also) for months I can actually understand what your are saying now, and it even makes sense in my uneducated brain! ... So keep being cocky Geek 8-)

Well, at first I actually meant "disposed".

But what i wanted to suggest, is that we should be able to use the pixels of the screen more efficiently than the current
separation which favorize too much vertical vision instead of horizontal one.

I must say, RoyMi6 , that you're example seems even better, the horizonal FOV would be even greater than in my first example, and no need to physically rotate the screen.

Maybe a simple prism like already existing on videoprojector (a simple lens can project a square, at a decided place, whithout being even aligned with it). would be enough.

I'm not saying I've the most perfect idea, I'm just giving a way of thinking, that maybe will bring something good.

Is there an optical solution to render each image rotated 90 degress, so that you render at 1080 horizontally ingame, but it's displayed vertically, then twisted use lenses and magic to look correct?

That could be what the OP meant

Ah yeah, it could be done with coherent fiber optics. Or surgical modifications. Or perhaps psychotropics... :o

Here is a model showing the surgical method required for wearing a Rift "improved" with vertical alignment as suggested by the OP:



@Tgaud: We are not poking fun at you. We are just trying to figure out ways that your interesting idea could be implemented in the real world that has physics and maths and stuff.

LOOOL shit i had to laugh so hard when i first read the main post, made a hard face palm, then scrolled down and saw that pic, priceless moment :lol:


well perfect would be these amoled displays one for each eye and cutted perfectly, so that we have perfect FOV on both eyes and dont have unnecessary black edges. will come some time in the future i guess

When Oculus VR will be a big enough company they will probably have enough money to make their own screen especially for the Rift. For the moment tho, they still depend on existing screens conceived for other big companies, mainly screens made for smartphones or tablets. Do you know about such a device that would have a HD square screen ? I don't, and this is why this solution is impossible right now.

As I was recommending in my "fresnel lens stack" thread over at MTBS3D, we could use anamorphic lenses to provide more horizontal FoV than vertical, but stretching the image less vertically and more horizontally. This can be done with stacked offset lenses, but that requires complex lens distortion correction. Using such custom lenses would certainly be simpler and less expensive than using custom displays, mirrors, or coherent fiber optic bundles.

Using mirrors increases the total distance from the eye to the display surface, which affects the optical path and therefore the lens selection (requiring much more magnification to achieve large FoV).

Semantics aside I don't see the issues people have brung up as being that much of a problem.



However you work it - same style screen just split vertically, or even if you rotate it 90 degrees as shown in the image above - it's not going to get steamed up or cut off your breathing :)

Something that hasn't been brought up is the fact the screen would be fairly unsupported when it's rotated "90 degrees". Looking up and down there has the potential for a lot of movement. Not a minor problem!

geekmaster - As I'm not member of the mtbs3d forums I can't see the image at the moment but the thread sounds interesting.

I'm new to this (no technical background in optics, just a software developer here) but one advantage I can see for this suggested setup (however you split it) is that the field of view when looking at either direction has the potential to be a lot greater for the eye that's looking towards your nose.

(Talking about the right eye) At the moment the way the screens are split means that technically there's no screen past your nose bridge. In real life if you look left you can obviously see further than this with your right eye. It appears to me that the rift compensates for this with the combination of "distorted" images towards the center and the optics.

It's obviously a compromise as I'd imagine it's seen as a fairly "low use" part of your whole vision. I assume as well that there's essentially a direct correlation to the amount of distortion applied to any given part of the image and the amount of final pixels that are apparently used when corrected with optics.

I.e. The more distortion the less pixels are used to cover the area.

This suggested setup would presumably allow for less distortion in this area (as well as the other extremes) meaning better image quality at the extremes and a and a wider FOV overall.

Still, interesting yes - practical... ehhh maybe not :)

sorry but i had to do this :)

Blimey! Now that is gonna be wedged in my noggin until I have a chance to exorcise it in the form of a Halloween Jack-o'-lantern! Crikey dude, that's too long to wait!
