Aha, we’ll see. (Maybe they just scrap the old lines – just to spite us, if nothing else… :P)
As you would indeed expect. Not noteworthily more so than current VR HMDs, though. :7
Maybe. Such multifocal stacks is a kind of solution that has always struck me as highly “inelegant” and bound to be absolutely riddled with drawbacks, though.
Decades old semiconductor lines are still around, producing the analog parts like amplifiers that everyone depends on. Old lines do not get retired generally, there is just too much demand. Moreover, customers want to design stuff with parts that will not be discontinued.
Not noteworthily more so than current VR HMDs, though. :7
Yes, much more so than even a Pimax HMD. That thing looks like it would be shuffling around everywhere whenever I turned my head.
bound to be absolutely riddled with drawbacks
Possibly not. Only one display might be used at a time, and such stacks of composite materials have been completely free of defects before, so it should be possible.
With such a mode of operation, you’ve still got no depth of field, though, other than what you might simulate with image processing, right?
Depth of field should come from the difference in image focus? Isn’t that the whole point of light-field displays?
You should have focus on stuff at the distance of the virtual world object you are accommodating to, which is usually the same as where you converge (I am assuming you’d be using eyetracking to select " focus plane"), but everything that is closer or farther in the game world needs to be out of focus, which it would not be, if it is rendered to the same plane – the whole world would follow your accomodating, much like the whole world is simultaneously in focus on the singular focal plane of current HMDs.
EDIT: Anyway - waaaay past bedtime. Good… err, day, I suppose, and thanks for the chat. :7
If the stacked layers cover the range of infinite distance focus to 1m, the depth of field that would result would have an approximately natural and typical range. So would the resulting vergence accommodation.
Good morning. :7
So by: “Only one display might be used at a time”, you do not mean that only one of the displays in the stack is ever active at any given time, with none of the others outputting anything? (…which happens to be how I am assuming the two-ply Magic Leap One works.)
If there are four layers, and the refresh rate is 100Hz, the panels would be switching at >400Hz. One panel is an active display at a time, at a specific focal depth.
Alternatively, I have seem some academic articles and photos of displays that use multiple layers to occlude the light field, like a 3D relief done with a few layers of cardboard. IIRC, those usually require tracking the observer’s position, and may not be relevant to VR.
Aha, flicking through the whole stack one by one, every frame; Ok.
Wouldn’t that be 10x10=100 regions? To get 9 regions (close to 10) you only need to go 1/3 size (not 1/10). Or do you really need 100 pixels for 10 regions? (I don’t know much about how light-fields work)
Oh, yes, that’s correct.
ah yes, having to take glasses on and off under the headset to see near and far. that is going to be so great. can’t wait. very immersive.
Incidently, one neat trick you could possibly do with lightfield displays, is to compensate for reduced accommodation ability in software. :7
That’s a good point, which I hadn’t considered. I’m not sure I want to wear bifocals in VR. 
The emitters will still be nearby, perhaps you won’t need to switch glasses for near and far vision.
One can hope

I ve been quite lucky to not have any issues with 5k+. I use normal fov and I don’t see any distortion. I’m just curious… anyone pre order reverb g2?
I would have no objection to an HMD with 8k curved displays and lenses.
as a solution before I later put a cable in my skull.
