From the Google Cardboard to the Apple Vision Pro & Meta Quest 3, VR displays, optics and headsets in general gone through a crazy evolution in 10 years. With fresnel lenses, pancake lenses, MicroOLED (a.k.a. OLEDoS, or OLED Microdisplays) and more, there is a lot of sci-fi tech to talk about.

Some additional information on the black frame insertion for those who are interested: The problem is really that the pixel response time of OLEDs is too good, with LCDs if you do 100fps, the display needs time to adjust, so you have a 'smooth transition' between the two frames, with OLED, that's not the case. The response times are so good that you get a sharp transition. Think of it this way with frame one being '_' and frame 2 '¯': LCD: _/¯ OLED: _|¯ OLED w/ black frame insertion: _ ¯ with our brain filling in a diagonal line in between.

Only fixed on quest 3. If the quest 3 had ps5 level visuals and cost $300, and had several half life alyx level games. than it would hit mainstream. But even now the technology isnt there yet. Comfortable vr that does not cause motion sickness has existed for less than 1 year.

@Mister0Eel VR gaming is held back because AAA game developers are saying there aren't enough users for them to make VR games. Gamers say there aren't enough VR AAA games. Eventually it will take over as playing Slyrim in VR then going back is like going back to playing pong. But AAA developers are all owned by a giant corporation that wants immediate profits now. Half hearted Sony and Apple VR and even Valve only making one game and Meta stopping PC game production is not helping. But it is inevitable.

This was a great breakdown. I'm surprised nobody has taken advantage of necklaces for compute and battery functions. Putting everything on the goggles themselves make them inevitably heavy, and when they do add compute/battery, it tends to be on a belt back or something. I think the ideal formfactor would instead be a small pack that hangs right beneath the back of the neck, and another small pack balanced on the collarbone, and then a flexible rubberized link between them so that the whole set-up fits loosely around any sized head and drapes lightly across the shoulders, not putting pressure on the front or mack, but on each shoulder instead. Then it would only need a short cable to link it to the goggles, while massively boosting the performance of the system.

The optimal VR display will have to be curved because our eyes move in an arc. Being flat vertically is probably easier to get away with, as the eye doesn't have as much range (about 65 deg.) as horizontally, which is 90 to 100 degrees. And we typically don't use the upper and lower extremes of movement as much as side-to-side. Having a lens mimic these curves is possible, but distortion is very hard to get rid of due to the small size and tiny distances involved.

I do want to add a bit off nuance. 100 nits sounds very dim but its not as dim as you think. Though I do have a Reverb G2 with fresnel lenses. While using VR, you completely enclose your face, this means it's near-pitch black in there, this makes any light that appears in it much brighter to your eyes. Our eyes are also amazing at accounting for low light so this also helps a lot. THen.. I believe Pixar does this but unsure, forces their video mastering for HDR done in a completely blacked out room, using 100 Nits displays only.

The eye, optic nerve, and visual cortex are separate and distinct subsystems. Together, though, they capture, deliver, and interpret up to 1.5 million pulse messages per millisecond.

I dunno man... there's a _lot_ about human vision that's just fundamentally jacked. The optic nerve connects on the wrong side of the retina causing unnecessary blind spots and those same nerves twist around in such a way that our visual cortexes have to do unnecessary work horizontally reversing visual information. Then you have all kinds of developmental wackiness with the lens requiring regular prolonged exposure to sunlight to form properly and it rapidly losing the ability to heal cataracts with age

@@MasterChaoko The ‘inverted’ argument for the alleged inferiority of the vertebrate retina has been soundly scientifically refuted, with multiple lines of evidence showing that it is in fact optimal for its environment. There are sound design reasons behind the arrangement, as the supposedly superior arrangement would require blood vessels in front of the retina, blocking out most light. In addition, one component of the retina’s Studies have shown that the forest of wires are part of a complex feedback system that actually improves contrast and sharpens edges without sacrificing shadow detail. As a result, compared to a camera, the human eye is far better at capturing contrast while simultaneously detecting faint details. Additionally, it has been determined that the ‘blind spot’ does not even slightly interfere with vision efficiency ☺️

@@TechAltarOh? Ok, so most of the people around me (and im swiss so you would think we have a higher afinity for french words) say it wrong, you learn smth new every day :D Im not into VR myself, just not what im looking for when im gaming on my pc or consuming other digital content, but from my hobby side i find the technology put into those things amazing. I guess because the resolution is by far not at the level of regular cameras (45mp +) it doesnt matter as much what lense you put in there and thus chose "light" and "compact" over "uber sharp up to 120mp" , which makes sense, i wouldnt want to put a heavy thing on my head for long times.

I just lost it when he spoke about holographic lens. It's seemingly like a scam. I just cannot believe it😂

I’m in awe for the technology behind the AVP, but I simply can’t see the use case for a broad range of users…

Loved this! Thanks! I’d like to know how Apple’s engineers feel about Meta’s holographic lenses; whether they intend to use or improve upon them. They’ve always got to put their own spin on a technology, so I imagine they’ll take forever to adopt and implement it with some ungodly number of pixels and nits, and give it a different name.
