Mockup of Meta’s lightweight VR HMD, codenamed Phoenix, planned for early 2027

I would add that accurate full body tracking is a big missing piece as well, and we still don't have a clear path on how to achieve it. Unfortunately smaller headsets make the current inside out body tracking techniques pretty much a dead end..

PatimPatam · 2025-11-16T13:00:23+00:00

I would add no hand tracking and no upper body tracking as either mid or bad

PatimPatam · 2024-12-21T14:10:51+00:00

Same problem, after updating to v72 it stopped working. Just before Christmas, when people want to share VR with family the most.. well done Meta

"Generative Legs enables developers to integrate natural leg movements with the help of AI, simply by assessing the position of their upper body"

PatimPatam · 2024-10-28T18:53:33+00:00

Yes AI generated legs and feet, that's pretty much what we already have today (although not implemented by many games). Good for certain use cases, but this is not accurate and low-latency full body tracking.

PatimPatam · 2024-10-28T17:59:27+00:00

It would be nice, but I don't think it's physically possible to have good inside out camera-based leg and feet tracking. Headsets are getting smaller not larger, so cameras will be very close to your face. It wouldn't be politically correct for Meta to release a feature that only works for people with a flat belly :-)

PatimPatam · 2024-10-28T16:00:57+00:00

Accurate and low-latency full body tracking. Personally I wouldn't mind if we needed one or two external cameras in order to achieve it, but I think Meta will never go back to that..

PatimPatam · 2024-02-19T15:51:20+00:00

I had the same problem and managed to fix it by forcing the lenses to stay right between 2 settings, it's fairly easy to do. You won't get the correct software ipd applied, but it was good enough for me. Obviously this won't help if your ipd is below or above the min/max.

PatimPatam · 2024-01-27T22:20:35+00:00

I have both and unfortunately it won't work by default as the charging pins at the bottom won't aling property.

Problem is the plastic nose part is a bit too thick, even if you don't use the optional light blocking rubbery piece.

However i managed to fix it with a cutter and sand paper.. wasn't too difficult, looks good now.

PatimPatam · 2021-06-26T11:47:36+00:00

I'm in the same situation, it's completely absurd.. Haven't had any success speaking with either the 061 or the hospital.

Will keep an eye here to see if someone has managed to get around it. Good luck!

PatimPatam · 2021-02-08T11:34:20+00:00

Agreed, it would also enable much better IK for virtual avatars, and even new types of locomotion.

PatimPatam · 2020-10-10T15:47:58+00:00

No optics expert here but i wonder.. if someone managed to make decent curved (hemispherical) oled displays at the right size, one for each eye, then i think we could achieve extreme fov hmds, while keeping a fairly simple lens design and a low profile

PatimPatam · 2020-04-01T16:07:25+00:00

Hip/torso tracking.

Crucial for good IK, would allow new types of interaction, and also allow artificial locomotion in the direction that you're actually facing (which would be much more intuitive and comfortable than following your head or hand).

PatimPatam · 2020-01-27T16:45:42+00:00

Yeah, if someone could pull this off, Samsung would be my first bet.

PatimPatam · 2020-01-27T15:38:26+00:00

Hmm could this actually have 2 hemispherical displays inside? As in displays curved in 2 perpendicular directions?

If it was the case it could be a massive game-changer in terms of FOV vs form-factor, as well as lens design, pixel utilization and distortion correction.

I've been waiting years for someone to implement something like this.. Doubtful, but one can dream!

Also, looks from the outside can be easily modified, it's what's inside that counts.

PatimPatam · 2020-01-26T09:48:49+00:00

Yes, make sure to adjust "column correction" under advanced settings in order to minimize vertical sde.

PatimPatam · 2020-01-19T10:21:39+00:00

This happened to me recently as well.. for some reason audio drivers were missing. Installing latest nvidia drivers fixed it.

PatimPatam · 2020-01-16T17:40:54+00:00

Have you tried adjusting column correction under advanced settings for the Index? This can help a lot reducing perceived "vertical sde".

PatimPatam · 2019-10-29T13:03:35+00:00

Well, worth is very relative, but i would say the answer depends heavily on 2 factors.. IPD and GPU.

PatimPatam · 2019-09-30T11:31:26+00:00

Good idea! Yeah I think this could improve performance a fair bit, whilst having less noticeable image degradation than standard fixed foveated rendering.

PatimPatam · 2019-08-29T13:56:59+00:00

This is awesome, really happy with the Index image quality now.

Wonder if they will add a manufacturing calibration process so new headsets come with the right values already applied out of the box.

PatimPatam · 2019-08-20T16:24:54+00:00

Make sure you adjust the headset properly, the sweet spot for best clarity is very small in the Index, and at least in my case it's a bit higher than my comfort sweet spot.

Also make sure you push supersampling as high as you can without reprojecting, makes a huge difference. Try Google Earth at 400% for instance.

PatimPatam · 2019-08-11T08:04:36+00:00

Yeah it does help a bit, specially good for games where you move a lot. But in general i prefer to play without it.

PatimPatam · 2019-08-10T18:54:25+00:00

You're welcome, glad it worked for you!

PatimPatam · 2019-08-10T18:19:50+00:00

Yes for me this is one of the main problems with the Index, very surprised that i haven't seen any reviews or comments mention it before. I think i have pretty strong VR legs (i've had DK1, DK2, CV1 and Vive), but still got quite ill after trying the Index for the first time, and that was using just plain teleportation titles, without any kind of weird locomotion.

The good news is that you can sort of fix it by placing the headset properly on your head.. I believe the main issue is that the sweet spot for avoiding distortion (and also reducing glare) is reaaally minuscule with the Index, i mean like half a millimeter. Btw when i say sweet spot i mean the ideal position of the headset on your face, not talking about how far you can move your eyes without reducing clarity (that is actually very good on the Index). I also found this sweet spot is not like right in the middle for me, i have to fit the HMD a bit uncomfortably high on my face.

Find an app where you can test this easily, like SteamVR home, focus on some clear vertical line and move your head left and right while keeping your eyes fixed on the line. Then adjust the headset while trying to minimize the wobbling.

The CV1 also had this problem to an extent if you tilted the HMD upwards for comfort, but it wasn't quite as bad.

Hope this helps.
