[Ars] Virtual reality that doesn't suck: my time inside Half-Life 2

post #1 of 29

The demonstration was put on by Forth Dimension Displays, a component maker that has managed to squeeze a functional, commercially viable 1080p monitor into a display area that measures a little less than an inch across diagonally (the company has also recently prototyped a similarly sized screen at QXGA resolutions of 2048x1536—the same pixel count as the new iPad squeezed onto a fraction of the size). By putting one of these HD displays a few inches in front of each eye, you can create an all-encompassing 3D effect that covers a roughly 100 degree field of vision in front of you (Forth Dimension also makes wider displays that can extend that vision field even further).

These screens are currently limited to high-end, specialty market purposes like professional camera viewfinders, advanced microscopy, and military simulation, but the Forth Dimension team has its eye on broader markets like architectural visualizations, virtual tourism, education and, yes, home gaming peripherals.

I'd like to see the 1 inch 2048x1536 display in person. redface.gif

Sounds like VR headsets could be coming back and in HD. Nice!

Ha, I saw the article days ago as well but paid no attention until just now when somewhere else focused on the screen instead the VR system.
2560 PPI? Once again, this just goes to show that any talk of technological limitations in making high resolution monitors is bogus. We should all be using 8Kx4K monitors right now.

The various prototypes of HUD displays have been floating around for quite a while, however, so far the price has been a litte bit excessive as they have not gone into a proper mass production so far. A 1080p is nothing new in this regard either - but I home these guys manage to pull it off in affordable package, not the usual 15000£ for 1080p (which has been the lowest I have seen asked for 1080p HUD).

For example a HUD display which was able to beam the image directly into your eye with tiny lasers was demonstrated already in 2001 if my memory serves me right.

The problem with these ridiculous resolutions is that we'd need a huge amount of graphical horsepower to be able to run anything on them.

I'm sure they could make you an 8K monitor if you wanted, but it's worth pointing out that your screen would be about 900 megabits per frame. You'd need 16 DisplayPort 1.2 channels or 20 HDMI 1.4 channels to drive a monitor like that at 60 Hz. DP offers 4 channels per cable, and HDMI offers 3 channels per cable. It'd be funny seeing 7 HDMI cables to drive one screen or 4 DP cables. heh

I suppose the point is that even if they could make the screens, and they could (expensively), we'd need a lot of advancement in GPU and link capability to drive them at their native resolutions.

True.


Many many years ago, IBM came into my lab at SGI and wanted to demo a high resolution display. SGI Onyx systems were the only computers on the planet (at the time) that could provide the necessary bandwidth to drive 4 display ports complete with edge blending. The display looked great, but at the time it was too small and expensive to be used for anything but tests.

A couple of these in front of your eyes, a surround sound headset, and some kind of gesture-based control (turn your head, move your eyes and arms), and you could have a great VR gaming system.

EDIT: And guess what? I should have read the article before I posted... because that's exactly what they talked about lol

Cool. Couple one of these with a Kinect (as the article mentions) and a omni directional treadmill and you are as good as there. Whilst the treadmil might be a little pricy for the average home used I can easily see something like this taking off in a cyber cafe / gaming centre type of setting. Buisines proposal anyone?


Oh and at first I was like:
Quote:
The company is currently talking with a number of "high-end peripheral companies" about putting all the parts together into a consumer PC gaming peripheral, which could be on store shelves "in about a year" after a deal gets signed.

biggrin.gifapplaud.gifbiggrin.gif

And then I was like:
Quote:
Forth Dimension estimates the initial cost for such a product would likely be $1,500 to $2,000, necessarily limiting the market to extremely hardcore gamers at first.

sozo.gifsad-smiley-002.gifsozo.gif

And then I was like:
Quote:
Considering that similar military training setups cost roughly $20,000 just a few years ago, though, that price will likely start coming down as production starts scaling up.

thinking.gif I'll wait.
