All of this really highlights how amazing the human eye is. What we're doing here is trying to match human perception and we're falling so short on so many levels it's kind of blowing my mind. Motion, color, depth, brightness, resolution... none of them are even close. There's probably more to it too. I can't wait to see what the future has in store for us.
And that's considering how shit human eye is compared to many other animals which have far better resolution, night vision, circular vision and what not
Finally, someone who knows what they're talking about when it comes to brightness. All the other dim-witted youtubers told us we were getting 1,000 nits of brightness on the Vision Pro, when the truth is that it's less than 100 nits.
The main issue is the lenses drop the brightness by 90% So the actual display might just be 1000 nits, but the user only sees 100 or so nits (in a light enclosed environment btw), so it’s less apparent

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.

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.

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.

(Quest 3, requires 120hz, and more importantly requires good persistence) Despite that, the quest 2 has outsold the latest xbox, and its has a lot of issues (that where fixed on pico4 and quest3)
@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.
I hold your channel in high regard for its educational value. Each time I watch one of your videos, I gain a significant amount of new knowledge❤ Love & Peace From Denmark 🇩🇰
to be fair, OLED screens are so dim because of temperature concerns. if you use BFI with a 20% duty cycle you can boost the brightness of that cycle by 5x and still land in the rated temperature range for the display. OLEDs really are the perfect technology for eliminating persistence blur
It's really incredible how perfectly well the Vision Pro is engineered down to its deepest details but we still have a long way to go, especially on the software side of things and creating truly immersive, complex, joyful and meaningful experiences (maybe only being solvable by advanced AGI).
Great explanation! It sure makes you excited for the development of this technology. One of the founders of Oculus has said that Apple is doing a "social engineering" tactic while releasing the Vision Pro: they know it looks like bulky ski goggles but the tech is good enough now and it has such a potential that they know that if people want to use this device, eventually even more people will opt in for bulky sunglasses with a cord that runs into a pocket computer that you carry around. The Vision Pro is only the first of its kind.
For the brightness issue you described, I understand that we should do better from an efficiency standpoint, but I don't think we need brighter VR displays. I always use my Quest 3 at minimum brightness anyways
I was expecting another mainstream take on vr but you proved me wrong, you did a good job to presente some of the problems vr still need to find solutions
Great video! You explained the displays and optics very well! I use VR every day and have for years. I can wait to see where we'll be in another decade! Awesome work
I have no doubt of displays becoming capable of 30000nits but is that really the solution? Cause that on a battery would last even less than the 2h quite small range of the vision pro lol 🤣
Working on improving the nits may not be the correct way to go, as the issue causing it to be inefficient are the lenses (and other factors). So makes sense to work on reducing the light that is lost
There are many channel whose Production quality is superb in all video. But this video has genius use of vfx, which makes explaining complex phenomenon simple. This is what vfx are for. And the way you explained all functioning of VR is just pure gold. I learned more in 20 minutes than hours of explanation. This was what UA-cam supposed to be. Putting my hopes on Nebula.
The Quest 3 is closer to Retina than the AVP since the AVP has a lower effective resolution. Apple intentionally blured the displays so you wont see pixels but that means the resolution is lowered considerably.
OH WOW! The virtual holographic lens is a game changer for virtual reality. This is just unbelievable because you will actually feel like you are there. Absolutely Amazing.

2% is insane, I had no idea it was so low. I was a big fan of the light field concept for VR, but this decreases resolution by a ton and also even MORE light is lost, so if this is a chokepoint I understand why no one is taking up light fields. Maybe it can be faked through eye-tracking? I read about holographic screens, but in the sense of wave guides. Taking a hologram of a lens is mindblowing. Blurring the display, while it hides pixelation, may cause people to try to focus, causing more eyestrain. I'd rather have a sharp display than eye fatigue.
Wow, that was a truly superb set of explanations, thanks! I'm now wondering how a future holographic-lens headset will be able to provide all three colours - seems like it should need very different holographic lenses for each of R, G, B, unless I'm missing something crucial... (Also that sequence at the start with the exploded headset... amazing 🙂)
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. To even approach the performance of this incredible task would take dozens of supercomputers, programmed perfectly and operating flawlessly and concurrently. Great design requires a great designer 😊
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 ☺️
Technically, OLED could be built, via a specialized controller, to mimic the 'slowness' of LCD, even if it just delayed the update of each pixel by a random number of nanoseconds.
as a photographer, i know well enough that fresnel lenses are chosen as a cost and size cutting meassure in camera lenses - as long as you dont rely on critical sharpness they are fine. Oh and isnt it Fresnel and not Frenel? At least in german you dont hide the S :S
@@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.
The beyond needs a face scan to order so that it adheres to your face perfectly so that less light gets in and out. This means even though its running at 400 nits it looks a lot brighter.
I remember back in 2015, right after Samsung released the 2K display S6 and S6 Edge to the public, news came out they were developing 11K displays. At the time, we were baffled about it, because who needs an 11K display on their phone? We were thinking wrong about it, because that extremely high density display would be utilized for other purposes, such as virtual reality devices. Now it makes sense.
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.
I was hoping you would mention the vergence-accomodation conflict that is inherent to any vr headset with a static lens. For me personally that is one of the major problems with VR as it is today. With low brightness you can (to a degree anyway) block out more outside light (like the Bigscreen Beyond), but the display will always be the same distance away, regardless of if you stare at a landscape or try to read a note up close.
@@andrejh8132 Yes, that's exactly the problem. From what I read online, the focal distance of the screens in the quest 3 is like 1.3 to 2 meters. So (assuming perfect eyes and no old age lens degradation) anything that is either closer than that or further away would be hit by the vergence-accomodation conflict. Your eyes converge on an object in the far distance, and your lenses try to adjust to get that distance into focus. But the screens are not 3D individually, and the lenses then focus *behind* the actual screens, making it blurry until you adapt, probably causing headaches along the way. By same distance I mean that, regardless of if you look at a virtual object 30cm or 300meters away from you, the *actual* distance at which your eyes need to focus to see a non blurry image is static, the optical path distance between your eyes and the screens.
Great video! I'd love to know more about the holographic lenses. I've known for quite some time that lenses can work in holograms, but I've only seen examples where the lens magnifies other elements in the shot. How do they make a holographic lense that magnifies something in the real world?
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.

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.
I hold your channel in high regard for its educational value. Each time I watch one of your videos, I gain a significant amount of new knowledge❤
Love & Peace
From Denmark 🇩🇰
holy, you have next level content, good freaking job
I agree
again great video! thanks for explaining these things and all the research you have done for it. love seeing these in-depth technology videos
Man every video you make is such a pleasure to watch, so well produced and even better researched.
Your dedication is amazing.
Can you make more technology business case studies like the Phillips one? I really enjoyed that.
to be fair, OLED screens are so dim because of temperature concerns. if you use BFI with a 20% duty cycle you can boost the brightness of that cycle by 5x and still land in the rated temperature range for the display. OLEDs really are the perfect technology for eliminating persistence blur
It's really incredible how perfectly well the Vision Pro is engineered down to its deepest details but we still have a long way to go, especially on the software side of things and creating truly immersive, complex, joyful and meaningful experiences (maybe only being solvable by advanced AGI).
Vision Pro is too heavy and it has a battery with cable attached to it ffs, its a terrible product to actually use
You have been killing it the last 3 months with these videos
Great explanation! It sure makes you excited for the development of this technology. One of the founders of Oculus has said that Apple is doing a "social engineering" tactic while releasing the Vision Pro: they know it looks like bulky ski goggles but the tech is good enough now and it has such a potential that they know that if people want to use this device, eventually even more people will opt in for bulky sunglasses with a cord that runs into a pocket computer that you carry around. The Vision Pro is only the first of its kind.
Its absolutely good enough for a lot of things, but will keep improving
This is a really informative video. Thank you.
This video is my new time pass while snacking. Loved each and every detail
For the brightness issue you described, I understand that we should do better from an efficiency standpoint, but I don't think we need brighter VR displays. I always use my Quest 3 at minimum brightness anyways
I was expecting another mainstream take on vr but you proved me wrong, you did a good job to presente some of the problems vr still need to find solutions
That was super informative. I didn’t think TA did this type of content.
Great video! You explained the displays and optics very well! I use VR every day and have for years. I can wait to see where we'll be in another decade!
Awesome work
I have no doubt of displays becoming capable of 30000nits but is that really the solution? Cause that on a battery would last even less than the 2h quite small range of the vision pro lol 🤣
Hopefully when we become able to mass produce screens this bright we'll also have better battery technology that can be mass produced to go with it
As you can see in the ending, it more likely is not.
@@neruwu so basically you need all the holy grails of tech to make this path work
@@andrijamunitic7320 hmm, we still need to somehow get quantum tech involved yet 🤔
Working on improving the nits may not be the correct way to go, as the issue causing it to be inefficient are the lenses (and other factors).
So makes sense to work on reducing the light that is lost
This video is really good, you explained everything perfectly! I wish I saw this when I first started out.
Sponsor message and product both well placed and well chosen; I watched it all.
When one does placements like techaltar I would always watch until the end. Very refreshing, isn’t it?
Great video! I love your coverage on this topic. Please keep an eye on it and make give us updates.
There are many channel whose Production quality is superb in all video. But this video has genius use of vfx, which makes explaining complex phenomenon simple.
This is what vfx are for.
And the way you explained all functioning of VR is just pure gold.
I learned more in 20 minutes than hours of explanation.
This was what UA-cam supposed to be. Putting my hopes on Nebula.
The Quest 3 is closer to Retina than the AVP since the AVP has a lower effective resolution. Apple intentionally blured the displays so you wont see pixels but that means the resolution is lowered considerably.
Best tech explanation of VR so far
Brilliant video. I thought I knew a lot about VR but learned much from you. Thanks :)
Great video!!! Very excited to see more than just SadlyItsBradley talking about VR tech like this
This was one of if not the best episode of yours.
awesome video. I loved the detail put in this piece. Also I am in awe how much tech is in the AVP and others.
This video is so much fun, really enjoyed every second 😂. Thanks for putting the time and effort into it.
Great video and technical discussion, with clear and understandable discriptions. Subscribed.
Fantastic breakdown of the whole problemspace
Excellent video as always, and what a great intro! That compositing is difficult and it looked superb!
OH WOW! The virtual holographic lens is a game changer for virtual reality. This is just unbelievable because you will actually feel like you are there. Absolutely Amazing.
Quick correction - the Varjo XR-3 had a micro OLED well before the Bigscreen Beyond
Man you video is very well done you explained everything perfectly and with cool animation gg !
Truly amazing video
I really think VR will be the next big thing sometime in the near future. We are not there yet but it’s only getting better.
One of the best explanations of Fresnel lenses.
Hey man, one of the best intros you have ever done. Great 👏🏼
Your videos are outstanding, such clear explanations
Hologram lens idea is crazyy
The fact that you can buy a headset using a pancake lens for $280 while also being a standalone is crazy.... I'm talking about Pico 4
Thank you for such a well put together video
Romans 6:23
For the wages of sin is death, but the free gift of God is eternal life in Christ Jesus our Lord.
Come to Jesus Christ today
Jesus Christ is only way to heaven
Repent and follow him today seek his heart Jesus Christ can fill the emptiness he can fill the void
Heaven and hell is real cone to the loving savior today
Today is the day of salvation tomorrow might be to late come to the loving savior today
John 3:16-21
16 For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life. 17 For God sent not his Son into the world to condemn the world; but that the world through him might be saved. 18 He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God. 19 And this is the condemnation, that light is come into the world, and men loved darkness rather than light, because their deeds were evil. 20 For every one that doeth evil hateth the light, neither cometh to the light, lest his deeds should be reproved. 21 But he that doeth truth cometh to the light, that his deeds may be made manifest, that they are wrought in God.
Mark 1.15
15 And saying, The time is fulfilled, and the kingdom of God is at hand: repent ye, and believe the gospel.
2 Peter 3:9
The Lord is not slack concerning his promise, as some men count slackness; but is longsuffering to us-ward, not willing that any should perish, but that all should come to repentance.
Hebrews 11:6
6 But without faith it is impossible to please him: for he that cometh to God must believe that he is, and that he is a rewarder of them that diligently seek him.
Jesus
holy shit, this is amazingly well produced. kudos
Amazing video! You did an amazing job explaining the various optics & optical illusions
2% is insane, I had no idea it was so low. I was a big fan of the light field concept for VR, but this decreases resolution by a ton and also even MORE light is lost, so if this is a chokepoint I understand why no one is taking up light fields. Maybe it can be faked through eye-tracking? I read about holographic screens, but in the sense of wave guides. Taking a hologram of a lens is mindblowing.
Blurring the display, while it hides pixelation, may cause people to try to focus, causing more eyestrain. I'd rather have a sharp display than eye fatigue.
Another well researched video from you, thank you very much, keep getting us properly informed.
Nagyon jó és érdekes volt ez a videód is! Köszi!
Truly a great, great video on this subject! That was wildly good, such a good job!!! 👀💯
Wow, that was a truly superb set of explanations, thanks!
I'm now wondering how a future holographic-lens headset will be able to provide all three colours - seems like it should need very different holographic lenses for each of R, G, B, unless I'm missing something crucial...
(Also that sequence at the start with the exploded headset... amazing 🙂)
Great overview of this tech.
Honestly this just further puts into perspective how cheap the Quest 3 really is for what you get. Insane.
Is this the highest quality tech video everrrr?
Finally all of my Quest 3 lens related queries answered.
This is the best masterclass on vr display technology.
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. To even approach the performance of this incredible task would take dozens of supercomputers, programmed perfectly and operating flawlessly and concurrently. Great design requires a great designer 😊
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 ☺️
Nice insights, thank you!
Technically, OLED could be built, via a specialized controller, to mimic the 'slowness' of LCD, even if it just delayed the update of each pixel by a random number of nanoseconds.
Damn, I remember VR in 1995. A big bulky stand in unit and now it's as big and heavy as military night vision goggles.
as a photographer, i know well enough that fresnel lenses are chosen as a cost and size cutting meassure in camera lenses - as long as you dont rely on critical sharpness they are fine.
Oh and isnt it Fresnel and not Frenel? At least in german you dont hide the S :S
It's a French name so you don't pronounce the s
@@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.
He's correct, the S is not pronounced
I re watched the opening 10 times, 3 of witch where on
slow-mo and I still don’t know how you did it. 😱 that is awesome
I never saw such a high amount of low persistence then in the AVP. And I used a lot of HMDs before
Dat animation is top notch
great quality video. I learned something new
Captivating presentation, thank you very much for this video.
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…
The beyond needs a face scan to order so that it adheres to your face perfectly so that less light gets in and out. This means even though its running at 400 nits it looks a lot brighter.
I remember back in 2015, right after Samsung released the 2K display S6 and S6 Edge to the public, news came out they were developing 11K displays. At the time, we were baffled about it, because who needs an 11K display on their phone? We were thinking wrong about it, because that extremely high density display would be utilized for other purposes, such as virtual reality devices. Now it makes sense.
The first time I am actually excited for something Meta is doing, wild
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.
That opening! So cool!!
I was hoping you would mention the vergence-accomodation conflict that is inherent to any vr headset with a static lens. For me personally that is one of the major problems with VR as it is today. With low brightness you can (to a degree anyway) block out more outside light (like the Bigscreen Beyond), but the display will always be the same distance away, regardless of if you stare at a landscape or try to read a note up close.
It doesnt feel like same distance, i need to use lenses to see far distance in Q3
@@andrejh8132 Yes, that's exactly the problem. From what I read online, the focal distance of the screens in the quest 3 is like 1.3 to 2 meters. So (assuming perfect eyes and no old age lens degradation) anything that is either closer than that or further away would be hit by the vergence-accomodation conflict. Your eyes converge on an object in the far distance, and your lenses try to adjust to get that distance into focus. But the screens are not 3D individually, and the lenses then focus *behind* the actual screens, making it blurry until you adapt, probably causing headaches along the way.
By same distance I mean that, regardless of if you look at a virtual object 30cm or 300meters away from you, the *actual* distance at which your eyes need to focus to see a non blurry image is static, the optical path distance between your eyes and the screens.
Probably the coolest intro ive ever seen
What a well produced primer!
Great video! I'd love to know more about the holographic lenses. I've known for quite some time that lenses can work in holograms, but I've only seen examples where the lens magnifies other elements in the shot. How do they make a holographic lense that magnifies something in the real world?
Brilliant video. Amazing visuals
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.
11:21 You mean 15000 nits.
Oh i didn't know about only ahowing frames for part of the time! That makes so much more sense
I just lost it when he spoke about holographic lens. It's seemingly like a scam. I just cannot believe it😂
