It depends on what setup you'll use them for.

Although, it seems pretty irrelevant, as it doesn't say how big they are, nor what the focal point is. But judging by the tweakers, I'm gonna assume they are too small to be used in a headset.

I would recommend Splashtop 2.

I have been testing out the 5x aspherics recommended by Palmer on a 7 inch Kindle fire with Splashtop 2 while I await my panel. I found that I have to center the lenses on the image not on my IPD. Is anyone else using the 2" lenses with a 7 inch panel seeing that as well. It looks really good just crazy that I can spread the lenses out like that and still see the image.

Using 5inch I'm afraid. If you look at the Freepie thread there is a script that gets the kindle to headtrack.

What rez are you setting the games to with Splashtop?

I use the 5x lenses on my 7inch headset, but I didn't center them. Do you mean that you can actually watch regular 3d images that way? Because when I can't change the overlap in software, I have to underscan the video just a tad to be able to match the stereo.

I used http://www.youtube.com/watch?v=jJjJeYfAwQw and some of cybereality's pireia driver testing videos to see if I could see in 3d and it worked. The lens centers are 8.5 cm apart, way larger than my ipd and I can see good 3d.

LOL quite the opposite! I think mine is a bit over 6cm. Under the norm which I think is 6.7 or 6.4 I cant remember. So I am looking through the inside edges of the lenses and the lenses are pretty much centered on the images.... impressive FOV but the edges of the screen are hard to see if there is any text down there. The vireio (bad spelling) driver correction on the youtube are impressive.

http://en.wikipedia.org/wiki/Pupillary_distance , which is a bit ethnocentric.

Chinese stats are a bit different. "Pupillary distance, the total average interpupillary distance was 57.9 mm, male: 58.2 mm, female 57.6 mm."

Possibly a better study, which is the kind of things a builder would need to investigate. The indication is of a range of build problems, as the differentials multiply out to being a 4x (either side of a pair of eyes) in a build:

Learning to Understand the collimation of binoculars (not just their visual qualities in-situ), and their exit pupils - was interesting.

Understanding that, and how CRT projectors utilize Scheimpflug as a component, is probably the path to getting Fresnels to work, if at all possible. (there are a few tricks hiding in there, but not yet explored)

I've done all that work over the past decade plus, now I'm trying to get up to speed with HMD's and their issues.

I am having two problems:


1) I can see the other side of the screen


Image


This is with the lenses set to approx 63mm IPD.
I can see quite a lot of the other side of the screen.
Either I have to move further away from the lenses, and get a lower FOV - OR I have to move them further apart=wider than my own IPD, that doesnt sound like it would work very well to me?

Green= roughly the size of the lenses
Blue=Furthest I should see without peeking into the other side
Red=the amount I can actually see
Yellow= Cannot see

2)The screen wont do 1280x800 and forces itself into 720p (leaving a tiny bar on the top and bottom) I ordered this screen and controller here:

Hello fellow DIYers, have you been following this thread?
DIY ULTRA wide FOV HMD for approx 500$

I'm just surprised that it's not getting A LOT more attention, because for me it's probably the biggest development in VR since Palmer announced his Kickstarter.

I mean, 180 FOV + possibility of having 1080p+ resolution PER EYE!


Personally I think it would be great if Oculus went for a similar design for the consumer version; I wouldn't mind paying a bit more and having to wear a slightly bulkier/heavier HMD in order to experience those specs! What do you think??

I like the stacked fresnel lenses. ;)

With that angled design, it would be easy to wrap it in a sexy curved shroud too! But it looks great as-is. And with two screens, much less distortion to compensate in pre-warp than my "supernatural FoV" experiments... :D

If Oculus' aim for the consumer version is just to appeal to those already really interested in VR, then, yes, that is definitely a way to go. I think the price + heaviness wouldn't work for a wider audience (it definitely wouldn't help, at least).

Yes but as Geekmaster mentioned the angled design would allow for a nicer HMD profile as well, which from a consumer perspective i believe is as important as weight (if not more). Looks sell!

Also think that the price mentioned ($500) is for the DIY version, if it was developed by a company like Oculus it could probably be much lower than that.

To get Doom 3 BFG to work with the Hillcrest tracker, use tmek's code which he released in this thread at this post: http://www.mtbs3d.com/phpBB/viewtopic.p ... 206#p92206 -- I'm really surprised that at the time of this writing, it's only been downloaded 9 times.

I can verify that it works, and that it's awesome.

So true! That HMD + the Virtuix Omni should really be getting 100X more attention.

thats similar to what i've been doing with mine. TrackIR + Tridef works quite well for sims.

ive tried it with Rfactor, F1 2012, Flight Sim X, Wings of Prey, Rise Of Flight.

What ive found with my experiments is that the resolution is a little low for racing sims, they're playable but its hard to make out things in the distance and which is an issue as they are coming towards you so quickly.

Flight sims are a little more sedate and things in the distance are generally much further away so its less of an problem.

As a side,

with the standard 5X magnifiers that most people seem to be using, i was struggling to get a filled FOV. (i could make out the edge of the screen both sides).
I solved it by getting some fresnel sheet magnifiers from the local book shop (something like these http://www.visionenhancers.co.uk/Fresne ... ifier.html)
cutting out a piece from the centre and then taping this over the eye side of each of the lenses.

it takes a bit of fiddling(ive just wedged my lenses into the ski goggles so i can adjust them easily at the moment) with but the image now does fill my FOV. however i think the additional magnification resulting from this setup does make the low resolution problem a bit worse.

My 5x lenses arrived today, beating the LCD panel oddly enough. Looking through them at a few screens I can definitely see the screendoor effect detracting from immersion. I may look into diffuser options if it's as bad as I expect.

Are you looking at a screen which is updated with head-tracking? Because that makes a big difference.

Wow good tip!

I just tried this with some credit card size fresnel lenses stacked 2 per eye, and now the "black bars" on the side are no longer visible. Also, "vection" has increased. Very cool!

What vittorio suggested should help a lot, as others have discovered. Even the stereopticons of old used a divider. Notice that this one has an additional tab parallel to the lenses:

The image pair in a stereopticon can also be moved toward or away from the lenses, just like in the Rift Dev Kits.

And the Hasbro My3D Viewer also has an internal divider. It works to help avoid being distracted by seeing part of the other image.

It's not the case for the Rift, it's the whole display + lenses assembly than can be extended or retracted from the eyes. It's not desirable for the Rift to change the distance from the lenses to the display, else you'd loose the ability to focus at infinity.

The geared mechanism is used to keep the eyes close to the lenses for people who wear glasses, have a larger brow or use different lenses.

Oh, yeah. I knew that. Brain fart! :shock:

I was only thinking about how they both moved the display toward or away from the face, and not which side of the slider the lenses were attached to (which determines whether or not that slider affects focus).

I just watched some game demos through my lenses on my 7" display and it's way less of an issue than I thought it would be.

rfurlan reposted it on his original tutorial link on the first page. I used it as a reference but ultimately had to make a new one for my all-in-one monitor. I just checked and the link still works.

Last night I finished the first version of my DIY HMD. I'm pretty happy with it. Building this thing has given me a much greater appreciation for the Rift devkit that I've seen photos of, they've done a great job making an ungainly shaped device look relatively good.

I think I might have broken my LCD controller :(

The display will shut off all the time, but it gets back on if I hold it in the right position. But I can't find a consistency in it to allow me to have it working in a reliable fashion.
