VR Headsets Are Approaching the Eye’s Resolution Limits
VR Headsets Are Approaching the Eye’s Resolution Limits
Some manufacturers want to go beyond that
Well, here's another example of the level tech journalism has sunk to.
163-inch 4K Micro-LED television that one home theater expert described as “tall as Darth Vader.” Each of the TV’s 8.3 million pixels is an independent, miniscule LED, a feat for which TCL charges over $100,000.
But here’s the real surprise: TCL’s new TV isn’t the most pixel-dense or exotic display ever produced.
No fucking shit, Sherlock. It is trivial these days to buy a laptop with a much smaller screen but exactly the same 3840x2160=8,294,400 pixels on it. Smaller screen, same number of pixels, more pixel dense. The Sony Experia Z5 Premium is a phone with that same pixel count.
Duh...?
The Vision Pro is wireless out of the box, but it’s somewhat heavy, struggles with meager battery life which, and can’t match the fidelity of Varjo or Pimax headsets.
Apparently nobody proofreads or does any copy editing anymore, either. Or maybe the whole damn thing is outsourced to ChatGPT now, who the fuck knows.
Ah yeah, because I have a frame of reference for how tall Darth Vader is! Like shit I know he’s tall, or he’s average and everyone else in SW is short? But that doesn’t help.
It's definitely written by someone who's never used a VR headset. It only takes a second to realize that these screens are nowhere near the resolution of your eye. Ya know, cause small text that would be easily read on my phone is blurry as fuck on a VR headset
I can see someone who only tried VR back 10 years ago, putting on an apple vision pro and being shocked that the resolution was so high, only to be informed it was a modest increase over other current headsets and that they are all pretty clear now. But really they should know if it was anywhere near "retina resolution", apple would have been all over making that claim.
I’m a bit surprised at the ieee hosting nontechnical articles. How long have they published “news” in this capacity? Archive.org suggests 2021 but it may have been earlier. Seems a poor decision for an ostensibly professional website to branch out like this. God, I hope .gov sites never start hosting blogspam.
ChatGPT writes much better than this article, here’s its response to your comment as an example:
Your frustration with the state of tech journalism is understandable, especially when it comes to covering high-end technology like the 163-inch 4K Micro-LED television by TCL. It’s true that on a surface level, comparing the pixel density of large screens to that of smaller devices like laptops or smartphones can seem straightforward. However, the engineering and design challenges involved in scaling up screen technology while maintaining image quality cannot be understated. TCL’s achievement lies not just in the number of pixels but in creating a large-scale display that maintains high-quality imagery, which is a different kind of technological feat compared to miniaturization.
Regarding the editorial errors and the critique of the writing quality, it’s clear that tech journalism, like many fields, faces challenges in maintaining high standards amid the fast pace of technology news and the pressure to publish quickly. While it’s disappointing to see, it highlights the ongoing need for rigorous proofreading and editorial oversight in publishing. However, attributing these issues to automation or outsourcing without evidence might not fully capture the complexities and pressures faced by publishers today. It’s crucial for the industry to address these issues to maintain credibility and provide the insightful, accurate tech coverage that readers deserve.
Yeah but I can't trust that at all. It may very well be complete bullshit, it just happens to be composed in a way that appears meaningful.
Remember what the sources are : you, me, marketing talk from product webpages..., certainly not the brain of a display engineer at Sony
"Did you know that the human eye only sees in 720p at 30fps? Your computer isn't better than my console" \s
24 fps*
I bought the 4k 120fps eyes. Sadly not all of real life is a available in HD anyways.
Call me when they hit the FOV limit too
Oh great, another round of nonsense about the limits of human vision peddled by A) companies trying to trick you into thinking their products are great, and B) fools trying to cope with their buyer's remorse and envy, and C) people with not-so-great eyesight who, for some reason, think that's inconceivable.
We are nowhere near the limits of human visual acuity. It is trivial to prove this by experiment.
Not sure I'd call $3500 trivial...
(/s...sorta?)
It's the framerate and response lag that is going to make it a motion sickness machine for folks like me.
And sadly, it gets worse as I age, so VR is running a losing race.
We have to speed up technology so that it outpaces us humans getting older!
PPD is really the big deal with the eye so close and foveated rendering being used. Was curious to see if they mentioned the limit of the human eye’s PPD resolution but I didn’t see it. Otherwise, a good article on the technology.
But nowhere close to the human eye's dynamic range...
I'm curious what this actually is. Yes, we can see under moonlight and also at noon in the tropics, but not at the same time. It's somewhat akin to the dynamic range of a camera --- an 8bit B&W camera has a gigantic dynamic range if you allow for shutter, aperture, and gain settings to be adjusted.
In other words, while the dynamic range of my eye over the course of an hour is maybe 60dB*, there is no way I can use that dynamic range in a single scene/"image".
*Just a guess from sunlight at ~1kW/m^2 to moonlight at roughly one millionth of that (super hand wavy I know).
I'm not sure if this is entirely true but I think one YouTuber somehow calculated and came up that each eye is ~500 megapixels
