Dear trinus staff.
I’m an optician and optometrist.
I wrote a mail whitout any response…… now i try with this forum
In order to give the best vr experience and reduce visual disconfort i can suggest a couple of test to regulate the best subjective IPD (the distance between right and left screen).
I also have a suggestion about the slider for IPD regulation: when i move it the image shift a lot!
Could be a pixel per pixel regulation? Every 5 pixel is about 1 prismatic diopter (calculated on oneplus one with installed in zeiss vr-one)!October 6, 2017 at 11:55 am #7301
Hi, sorry I missed the email.
IPD works differently on SteamVR and non-VR games. I assume you are talking about non-VR games, is that the case?October 6, 2017 at 5:32 pm #7304
No problem about e-mail. I suppose you recive a lot, and i’m glad to see your reply here.
1st of all: sorry for my english, i write from Italy
I’m talking about both: steamVr and not steamVr games:
In both cases we have a couple of images in front of our eyes, and differnces between the 2 images make 3d depth sensastion.
To reach confort the center of each image must be aligned with the center of respective eye.
So if i have 62 mm between the two eyes, images must be 62 mm between them.
If everithing is done right both eyes will have theyr images in the middle of fovea and 3d will gain depth.
But we have tho other problems: Differnt cardboard, smartphone, lenses, prismatic effect. How we can deal wit all these parameters?
In optometry we use different test to know the position of eyes and image of retina.
Two of them are very easy to be done with cardboard and are adapt to place the images in the exact center of user’s retina.
1st-shober test (i have one prepared for cardboard)
2nd-disparity fixation test (i already have one prepared for cardboard)
they are a couple of images that could be projected in smartphone (actually i used the gallery for my test.)
These test could be integrated in Trinus and IPD slider could be moved to adjust them.
I’ve noticed that IPD slider in trinus move the images a lot… and with this method we can achieve the best result.
i’m sending a mail with the 1st file.
Let me know if arrive!

Got the email. I’ll check the IPD slider precision.October 6, 2017 at 8:44 pm #7309
i have checked again slider precision. I was wrong and it’s perfect.
Was a mouse problem. Using arrow keys and i was able to adjust pixel by pixel to reach a perfect centered image!
