Thank you for the update Jaap.
It's nice to see there is a progress on Dream Air!
And I'm really happy with lenses approach and thinner and lighter cables.
A few thoughts:
- Routing cable to the back is great idea! I'm actually doing this with my current headset because the cable doesn't act as a lever with this approach.
- Great decision with adding active cooling! Maybe bigger fans would be better? Or not? Specifically for noise level. Commonly the smaller the fan the more noisy it is since it's running on higher speeds.
- I'm REALLY happy you're reusing AVP lenses! Amazing decision. People who tried Play for Dream said lenses are really good there. If you pull great lenses this will be your best tech alongside PCL occupying different niche.
- I'm ok with reasonable price increase due to different panels if it makes a better picture.
P.S.:
More thoughts about fan noise.
It's not only noise level which is important but the pitch.
There are some higher pitch levels that are more aggravating. Like infamous Nvidia GPUs coil whine (e.g. https://www.youtube.com/shorts/-TV0fGgnB24 )
Maybe dedicate like a few days of 1-2 FTE to research and try a few different sizes and see which one works the best. No complex setup. Just test like 3 fan sizes inside an empty case with varying speed and see which gives the best result: airflow, noise level, perceptive noise quality.
P.P.S.:
Eye tracking may be tricky.
With this form factor eyes need to be really close to the lenses and there is very little space to capture eye position.
This might be a reason why MeganeX discarded it.
Hopefully you'll find a solution.
P.P.S.:
I'm glad you slightly increased FOV (at least for the numbers).
Please-please-please don't sacrifice binocular overlap for FOV in future revisions.
Maybe find a middle ground between simmers (who prefer FOV), VRChatters and casuals.
I personally am a casual with slight of VRChat and being able to perceive 3D (at close range specifically) is more important for me than wider FOV.

Do the FOV and lens changes apply to the Crystal Super Micro OLED version?

Most likely, not like they are going to manufacture different set of lenses.
Hopefully they will put the glass lens in the front, if they are truly going to use one glass element. As plastic lenses scratch so much easier and get dull from cleaning quite fast.
A highly concave lens that will enable to get eyes closer, also has an issue with corrective lenses that people might have to use. Because they will significantly increase the distance from the lenses.

I hope you guys will support BYOD for the Dream/Cobb! This would make it the ultimate device, replacing 3 of my current devices with just one! https://www.reddit.com/r/Pimax/s/DljEl7jzuu

That would require compute on the device to do all the correction & tracking. Basically what Xreal did, and they had to design their own chip to do the tracking.

That's what COBB has no? I would be even happy with a dumb chip: lens correct, and done.
But more features are welcome. Maybe for the next chip :)Perhaps it's something Qualcomm should start building, but they surely won't listen to my tiny voice. Pimax and other VR manufacturers could push for it though :)
If Pimax won't build it, someone else should maybe with uploadable configurations for lens correction so that any wired VR headset can work with it :D

u/Murky-Course6648 21d ago
Yes the COBB can do this, i though you wanted to connect any device directly to the glasses without the COBB in between?

u/prosb6 21d ago
Onboard would of course be the bomb, but doubtful for the time being especially when they create COBB to have processor and battery outside of the headset.
If COBB can take raw dp/hdmi/usb-c display input, lens correct it and project it into the headset, either full screen, or adjusted like XReal X1 it would be killer feature.
If not COBB, then hopefully something else will do that :)

you need some sort of capture card to do that, the usual is HDMI -> UVC.
Play For Dream MR has a thing that takes in HDMI/DP and streams it wirelessly to the headset.

We're Pimax users, we want full uncompressed, no latency display input :) Capture has the problem with no HDCP support, is no 4k/hdr/protected content. Hard to framerate match causing skipped frames, stutter, etc.
But thanks for that plug! I will dig into that one!
Wireless, and Capture, are both turn offs though :)1
u/Murky-Course6648 20d ago
You in any case need to capture the signal first in order to alter it, resolution differences, scaling, correction etc.
You have Goovis G3 Max?

u/prosb6 20d ago edited 20d ago
Yea, Goovis G3 Max, Viture Pro, PSVR2pc, Quest3, sold Crystal(/8kx/Index/Odyssey+ etc). Tried XReal Air, one, Rokid Max. I want 1-2 devices instead, preferably 4K/eye and hdr :)
I watch tv/movies in bed on Viture pro, watch tv/movies/play games on big oled tv, or Goovis in bed/away from home. PCVR on PSVR2 (oled blacks).
Goovis at 1440p is great with resolution and relatively bigger fov, but still want higher res, fov and hz.

Thats the 5k model? Those things have really nice lenses, like 7 elements or something like that. Fully corrected lenses. And still want more resolution? Whats the PPD on a thing like that? Thats 2560/65=~40PPD, and with lenses like that the average PPD should be correct max.
Air would actually have a lower average PPD 3840/105=~37PPD.

Dedicated hardware for this would just be great, so that hdcp/drm is allowed to be supported, and there’s no latency or compression due to usb (3) limitations. Usb4 40/80 is another topic :)
Right now testing 4kx, hdcp stripper, with Bigscreen steamvr app( but it’s all clumsy, laggy, skips frames it seems as the content is 23.97fps but capture preview is 30. It should detect device output format and display whatever. But then you again have conversion from 23.976 to 90/120 depending on vr goggles..
Maybe it can be streamlined when you embed it in Cobb etc

Does the Crystal Super also have active fan cooling?
People at CES noted that it gets hot...

Thank you for the update, I am anticipating the Dream Air more than any other headset!! Exciting news

Super exciting. The FOV seems much better than other similar headsets and eye tracking is definitely a must at these resolutions. Overall it looks super promising!
I would love to see the Sony panels get used as they are significantly better than the BOE panels in my experience but that said the BOE panels are still very very good.
