Eye of the Serpent...Sony shows the future of stereoscopic displays for the PS4.

I still use the original Sony HMD for PS2 when I play PS2 games in bed, before going to sleep.
They are awufull, and the resolution is something like 320x240, but it is the best way to play laying down in bed.
I really look forward to get my hands on a HD HMD, especially if it is 3D. Awesome!
 
Off-topic but laser surgery does not stop normal eye deterioration. Depending on how old you are you may still end up needing glasses at some point. At least that is what I was told by the last optometrist I went to. The big change comes around 40 and is called "presbyopia" I believe.

Cheers

My doctor told me i should be fine at 50 years old but they have developed another laser surgery that they believe will allow you to go from 50 to 80. Apparently your eyes see less changes from 50 to 80 than 20-30. I got mine done at 28. So if i can get a good 20 years before i need glasses of any time , i'm very very happy.
 
From reading the article, I'd say they're doing it right. I'm very interested in this. It has the potential to be affordable enough to use, and when you go virtual reality, you need a personal display anyway. As long as they have learnt enough from previous failures to do it right this time with no medical implications, I have good faith in this as the quality of the picture appears to be very good already.

@Humus: my thoughts almost exactly.

Agreed. Most appear to have skipped over the OLED display part. OLED is very light flexible and is it's own light source. It is perhaps the only display technology that would be light enough and thin enough to work.

The CES 3-D glasses were prototypes built rugged enough to survive as Demo devices at a show and have glitz (led lighting for Sony logo and styling). I expect a final design to have a min of 1080P resolution and possibly 4K. At that resolution it would have multiple uses for Computers, Games, Virtual reality (with a model that motion control tracks head movement).

Sure the OLED panel is light, but as MfA mentioned having the image appeard to be directly in front of your eyes like you would with just a naked OLED display is not a comfortable nor easy to view option.

You'll notice that the Sony system has an array of optics used to make the dispaly appear to be farther away from the eyes potentially trying to mimic say an 80" screen at 2-3 meters distance.

That isn't going to be light. As well you have the light isolation shell which is going to be required if you want a good experience (something seriously lacking in the Apple patent) which is going to add more weight. Throw in headphones and a fairly hefty cable for power, video, and audio and that's more added weight.

And then there's always going to be the issue that your eyes will be focused on a fixed distance, somewhat similar to reading a book or using a monitor. Both situations that are known to have negative consequences on eyesight if done for extended periods of time. But at least with those activities you'll still have minor variances in distance (moving book around, leaning forwards and backwards in your chair) to at least give some focal variety to your eyes. HMD's aren't going to have even that. Which again is why you want systems with an array of optics designed to make your eyes focus on a point which appears to be 2-3 meters away.

No, I'm afraid there is a definite limit to how light you can make a good HMD.

For data, it can use WiDi to eliminate cables. Power is going to be a problem, it's either cords or batteries.
 
MfA introduced me to DOE/HOE specs in the Virtual Boy Returns thread. This it the real future of HMD; or at least, the idea of having it wrap around the head, elliminating the need for heavy and bulky optics.

I think we're still years away from a workable retinal display.
While the projection portion is now practical, the exit pupil is just to small in the designs I've seen.
Having said that optics isn't exactly a subject I'm an expert in, so perhaps there is a way around this that I'm missing.
 
The display described there is not a retinal display.

The DOEs just replace traditional refractive/reflective optics to change the distance/size of the virtual image.

The DigiLens model is a projection, 'folded' along the length of the glasses arms. And from that thread, it sounds like these projections can be adjusted for viewing distance and focus correction. It sounds very new and I've necer seen anything like this demo'd at a show like CES, but I can't see VR glasses taking off until this tech is employed as the negatives outweigh the positives in conventional dual-screen tech. Standard active 3D glasses are enough of a turn-off for lots of people!
 
There are all sorts of issues with designing compact wide FOV HMD's, I've never seen one.

Theoretically you can work around this by not using a physical screen and projecting directly onto the retina. The problem is that anything that doesn't employ an actual screen has to project through the pupil, and every design I've seen requires very precise positioning of the projector relative to the pupil.
Any solution to this AFAICS requires dynamic tracking of the pupil and real time correction. But there may be some clever optical solution I'm missing.

The Military would be happy to pay a lot of money for a compact wide FOV High res HMD, and they still don't exist.

In a lot of ways the tech has moved backwards in the commercial space over the last 10 years, designs are more compact, but resolution hasn't increased dramatically, and FOV has dropped into the 30-35 degree range.

I think efforts like Sony's are laudable and interesting, but until I see FOV figures, it's just vaguely interesting.

I don't see the pressing need for the miltary ... a wrap around stereoscopic screen with shutter glasses serves them just fine in most cases.
 
Well, a retinal display would in theory increase operational uptime for the devices and/or reduce the battery pack required to be carried by a soldier due to decreased power useable. That is something the military is keenly interested and would indeed pay quite a bit for. I think it's fair to say there is military funding going into research in those areas or at least in more power efficient display systems.

Heh, with current solutions you'd be introducing a whole LOT more weight to the HMD than you'd have with a wired solution. And that's just for the WiDi receiver (not small or light). Add in batteries and you're going to compound the issue.

Yeah, I mean, clearly we should have skipped the whole LCD screen fad anyway and stuck to CRT for the time being because it will all be replaced by something better 10 years from now. :yep2:

I most definitely hope CRT technology dies for good and forever. I never ever hated any technology more than this one.

I've been using PCs for long periods of time after 1995, when I bought my first computer.

I was born myopic, I got it from my mother, and I've been using glasses and contact lenses since I was 3 years old. Short sightedness usually increases as a natural process, not because of ageing, but because of the nature of it. That's why in order to have an eye operation using laser to remove all the dioptres you have, doctors ask you to wait two years getting ophthalmology checkups before performing a laser operation to have your myopia removed.

After I began to use desktop PCs every eye checkup I had showed that my myopia was increasing significantly. I used to change glasses every two years or so -sometimes after a year-. This happened for about 12 years, until 2007 or so when I began to use laptops with LCD displays and a HDTV, and realizing how extraordinary they are.

CRT displays have been burning my eyes out for a very long time and I'm thankful they are a thing of the past. Too bad I had to deal with that technology for so long.

Thankfully, after the last checkup I got less than a month ago, for the first time in my life my short-sightedness didnt increase -it has been 3 years since I bought my last glasses-. It felt amazing for me.

It always increased no matter what.

As for this technology, I'd rather prefer some more comfy and natural glasses, but other than that it might work. During the last checkup I got the ophthalmologist made me wear glasses with glass lenses exactly shaped like that and he began to perform tests while I was wearing them.

One of the tests involved looking in front of you and trying to discern 4 rectangle shaped lines, one at the top, another at the bottom, and then one by the right and left.

It was meant to measure my capacity to discern depth. I passed it and it was really cool to see and discern everything in 3D. So I think it might work well, but it should be less bulky to be practical, like wearing your everyday glasses.
 
Purely coincidence. Nearsightedness will naturally stop progressing and start going the other way when you get older.

However, it is exacerbated by focusing on near objects for extended periods of time (using a computer or reading a book for example). A CRT is no worse and no better than a LCD in this case.

I and many others went through similar progressions when all we had available was CRTs. LCD's weren't available to consumers when my nearsightedness stabilised. And yes in roughly the same time it took yours to stabilise. :)

Uggh, I feel just awful right now. I thought CRT technology helped me immensely to accelerate what you define as natural progressing of nearsightedness. I've been convinced of it for the last few years because I noticed it is a LOT easier to me to focus on the image (without getting tired) when I'm using LCDs.

When I had CRT displays, which were also bulky and heavy as hell, I also remember being able to distinguish the little "cells" forming the pixels, which I can only define as honeycomb like shaped. I had a feeling my eyesight capacity was falling fast and at that rate, I may not be able to keep at decent levels in order to get a laser operation --which I currently ruled out forever- or at least not to experience a huge increase of my myopia.

It is relieving to know that it wasn't only me who noticed that.

Cheers
