DK2 vs Colorcross/GS3 + Tuscany + Side by side ///Shocked

So...

After I put in an order for the DK2 back in early August, I knew I had a long wait but wanted to experience some VR so ordered the google cardboard and soon after I found a plastic china made version on ebay called colorcross for around $40.
I played around with the colorcross for a few days and it was pretty cool but I wasnt blown away and so here it sat in my desk drawer untill this morning.
I have had my DK2 for a week or more now and have tried about every demo out there and had alot of time to play with it and mess with settings etc... So I remembered this morning after running tuscany demo on Dk2 - that I remembered also playing that demo on the colorcross on my old galaxy S3 so thought it would be fun to load both versions up and do a side by side to see how much better the DK2 was than the colorcross/old phone.

To keep from babbling ill just try to get to the point, Instead of laughing the colorcross off as inferior I was shocked when comparing them side by side that the phone version of Tuscany seemed to have much more vivid colors and even more detail than the DK2 version. I also was surprised how with the cheap china lenses of the colorcross I could see all the way to the edges clearly! The DK2 version also seemed more washed out.
Now dont get me wrong , the DK2 is amazing and its head and positional tracking are miles beyond anything Ive tried on my phone but this old galaxy S3 is only 720p so would really like to try a higher spec'ed phone.
But yeah, the resolution is lacking on the phone and framerate is horrible but also noticed I never got that queezy feeling I get everytime im running around in Tuscany on DK2, but I think maybe that has to do with the tracking being so much smoother and more lifelike in the DK2 and that my brain is tricked more into thinking im really in this world and that my body is rapidly moving around when it really is not.

The colorcross is cheap and very uncomfortable but the clarity of the images just really surprised me. It seems on the dk2 only a circle about 40% the size of the lense in the center is clear and things any further out towards the edges are a muddy mess.
Im not talking trash about the DK2 or affiliated with the colorcross, it was just some impulse buy I made and its cheap and hurts to wear longer than 10-15 min, also I dont even think its sold anymore but was just shocked how clear the image was in the entire FOV.

On the DK2 I ran Tuscany in extended and yes was getting full 75 fps with no judder.
Again im not bashing or talking bad about the DK2 , just sharing my experience and wondering why the DK2 lenses seem so blurry at the edges when this cheap contraption has a crystal clear image spanning entire fov (although its apparent FOV could be smaller I understand this)
Ive also spent hours measuring my IPD with digital calipers and using oculus config, and also measured the IPD distance of the colorcross once I had it set (adjustable IPD on it) so its not a misconfiguration of the DK2.

Anyway ..... here is some side by side pics.

One last time... Im not knocking the DK2 - its miles ahead of this little device, Im just shocked and wondering why this other things lenses are so clear over the entire fov compared to the DK2 and why the DK2 version of tuscany seems kind of washed out and less vivid.

    Just re-read my post and feel bad like im bashing.... but really am not. Hoping someone can explain the lense issue for me.
    Is it that the rifts FOV is much larger so its a compromise with the lens design?

    Not having one I can only speculate, but it sounds to me like the lenses aren't distorting the picture nearly as much, thus giving you far worse FOV but a much sharper picture. Just like how the Rift screen is much sharper and brighter with better colors when seen directly with a lense taken out.

    Yeah, this is what im thinking as well. It just seems so blurry in the dk2 around the edges, I would gladly give up 10 degrees of peripherial blurr to have a slightly smaller but completely useable clear image.

    Again, the rift is amazing but the lenses have been my biggest disapointment. I constantly feel like my left eye is going crosseyed or blurry... its like strain on my eyes, so im constantly shifting the rift around on my head but can never find that sweet spot, i duplicated this feeling by purposly setting the IPD lense distance way too narrow on the colorcross.
    My IPD is not that wide either... the config program says 67mm but after checking 3 times today in the mirror with digital calipers it is 66mm. This is not far off from the average 64mm the dk2 is designed on so dont think its a ipd issue although an adjustable ipd lense setup on the cv1 would be nice.

    So yes... i just assume its a design compromise where large fov is compromised with blurry edges.
    A smaller fov would take away immersion but a blurry outer 50% fov just doesnt agree with me (perfect vision btw)

    Anyway... curious as to what the lense setup in cv1 will be. Hopefully glass and resolves these issues.

    I did a very unscientific test to compare the fov between the 2 HMD's.

    Loaded up tuscany again in both units. Picked a spot on the wall to face while I swapped between the 2 units.
    I positioned the game camera controller (player) at the same bush in front of the tuscany house and placed the tree in the far left corner of the yard just inside my left side fov. without moving my head i slightly lifted up the HMD and placed a marker on my desk (coin) that represented this edge of my fov. Then I repeated to confirm marker location. I then set a marker for the farthest I could see to the right of the fov and placed a marker and repeated to confirm.

    Did the same with the dk2 and the fov is pretty much the same between the 2, maybe the dk2 is 10 degrees wider fov but the outer fov is blurry.

    This got me thinking. Before I got my DK2 or the colorcross even, I ordered a quality pair of german made glass lenses to play around with. I tried them in the google cardboard and they looked fantastic.

    Makes me want to try and mod my b lens cups to house these or figure out how to 3d print a pair (probably too expensive)
    I first need to find the focal length of the lenses and see if its close to the dk2 lenses.

    Am I the only one who has tried a mobile HMD and find the lenses to be much clearer than the dk2 :?:

    Im hoping sometime in the future there will be upgraded (hopefully glass) optics available for the dk2
    I used to be pretty serious in amateur astronomy and had some really expensive equipment. I know firsthand alot of cheap eyepieces suffered the same distortions. I know wide field of view eyepieces suffer from chromatic abberation and distortion along the outer edge of the image. To get around this you need a multiple HIGH QUALITY (expensive) glass lense design to minimize this distortion. I know the dk2 uses software to correct some of this but I think theres only a limit to how much software can fix a cheap plastic lens. I know production costs for good quality glass lenses for the dev kits might not of been in the budget. But I sure hope cv1 has a better pair of optics in it.

    I myself would definitely pay more for a quality set of glass dk2 lenses that bring a wide full clear fov.
    Im hoping in the future this may be an option from oculus.

    I just ordered one of those colorcross headsets. I look forward to trying them out as I have only used DK1 and DK2 so far (and pre-oculus 90s vr).

    I wrote a review of mine on amazon, they are good for the price they are now but like i said. Very uncomfortable and you can see the divider in the lenses. Seems like the lenses need to be closer to the screen to fix this, I thought about doing this but my dk2 is here so dont use the colorcross. The colorcross lenses work good but again, its limited.

    Heres a question I might have to start another thread about- but is there anyway to turn up brightness and color saturation on the dk2? I think the tuscany demo looks so good in the colorcross because i have the brightness up on my phone.

    In nvidia controll panel my brightness and color was set to 50, i turned them up to 100 but seen no difference. Even after computer restart I saw no diference. Is the dk2's brightness and color locked out by hardware in the device?
    Shouldnt it be able to be adjusted just like any monitor?

    What am I being jipped from my VR experience from cheap plastic lenses! Now I’m pissed

    Im not upset since its a devkit and pretty impressive even with the blurred outer fov.... i just hope cv1 sports glass, and hopefully some optics makers will offer aftermarket glass lenses in the future for replacements if ovr doesnt offer them.
  • DK2 has an estimated 100° FOV. What would you guess ColorCross's to be?
  • TWhiteTWhite Posts: 363
    DK2 is 106 degrees vertical and something like 87 degrees horizontal, maybe less.

    Honestly, these DK2 lenses are junk, really really bad. If there was one improvement I'd hope for more than any other in CV1, it's high quality lenses. The sweet spot on that colorcross is just amazing, the whole image is sharp. I have to have my DK2 lenses touching my eyeballs to get that much sharpness out of it, and even then it still doesn't look that good.

    Id say around 85-90. I think it would be wider if you could get the screen a few mm's closer to the lenses so that your seeing all screen and not the phone and dividers at the edges.

    This has been my experience exactly! Glad im not alone, i felt bad that my $400 dk2 was opticaly outperformed by a cheap $20 ebay item. I hope a 3rd party steps up to grind some good glass for the dk2's.

    I was going by the 100 degree estimate. How'd you find out it's 106?
    "Ultra Wide Field of View
    The Oculus Rift provides an approximately 100° field of view, stretching the virtual world beyond your peripheral vision."

    You all and these lenses! Argh! Was going to ask for one for Christmas, but not when they've yet to get the(one of the, at least) most important parts right!

    Thanks! Hmmm... I think I may go ahead and use this AB plastic and goggles I have. Bought a 7" screen and controller board, a while ago. Sounds like the Colorcross needs some adjusting.

    I have a Note 4 and am eagerly waiting for the Gear VR but now i'm a bit worried that the lenses are not that great either.

    But i read that the FOV is smaller and rounder than that of DK2 and therefore maybe have a wider sweet spot.
  • Deez, have you tried removing the lenses and putting them on the other side like this?: http://m.youtube.com/watch?v=HdcNRudoRGU

    Good find!

    ill have to try it but affraid the lenses will then be too far away from your eyes.

    The best solution I think would be to have the lenses where they are are suppossed to be but bring the screen closer to the lenses so you dont see the edges of the phone and so much of the divider.

    I also wanted to try the colorcross lenses taped in the dk2 but havnt got around to it.
