3D/2D switchable LCD monitor from Sharp
Roy Sigurd Karlsbakk writes "Sharp just came up with an
LCD monitor that allows you to switch between 3D ( no glasses ) and 2D view. Wanna play quake and have a slight heart attack?"
Now thats what I'm talking about!
Oh wait, it's not the monitor, it's just the double post on Slashdot!
The next Slashdot story will be ready soon, but subscribers can beat the rush and slashdot the links early!
Oh sorry... that green color of slashdot just LEAPED at me...

I'll go out and drop a pile of cash on one of these. About the time I get tired of switching, they will have a new version with autoswitch!
See how they are?!
Well, they did a few years back anyway. I remember my friend challenged me to a game of Rise of The Triad in a booth at some theme park. The main attraction was that to see the game you got to wear these fancy looking 3D goggles. It was something like $3 a person, so I figured what the hell.
That was the worst first person shooter experience I've ever had. Maybe the goggles weren't focused right, but I got incredibly dizzy from playing it and ended up not being able to do much at all. Maybe a slower game like Icewind Dale II would be more playable in 3D, but then, what would the point of that be?

I'm not a rocket scientist, so if anyone more clued-in on the inner workings of monitors and 3d game engines could explain to me: can we ever expect something with a similar effect working on a CRT monitor?
I am moderating the slashdot website as -1: Redundant.
I couldn't fail to disagree with you any less.
now we'll be able to read slashdot in 3D.

I can think of one really cool application. Maptech makes a product called terrain navigator which shows USGS topos in 3D using the standard 1950s 3D movie style glasses. However, dedicating the color dimension to getting a 3D effect means the information densities you can get on the screen are somewhat lessened. Governments often spend a lot of money to get higher resolution elevation data. I know of several counties in FL that have 1m LIDAR for their entire county for flood control. Combine this with color aerial photography and you have a kick-ass visiualization system.
The technique used in the display reminds me of the old 3D post cards.

So I call hoax.
Cool! Hey, somebody should submit this as a story to Slashdot. I know the people there would love to hear about it... again.

Don't piss off The Angry Economist
Does anyone know what the vieuwing distance must be to see the 3D effect?
I think that "parellax-barrier" only works when you are right in front of it and at a certain distance from the screen. Else, for instance, the data for the right eye will meet the left eye, thus killing the effect.
Can anyone confirm this?
Cool stuff.

Think there might possibly be some interesting applications for a screen such as this that could also function as a touch screen? I know, 3D, Flash porn! You could undress her 3D body interactively! Or you could just go get laid...

The nice thing about emerging technologies is that it tends to lower the cost (and eventually the consumer price) of "legacy" devices already deployed. I'd much rather have a 21" flat panel for the price of a 15" flat panel. Even better, it will allow standard 2D flat panel screens to retire CRT-based monitors as the mainstream display device.
Ayup
The other story was about a 3D monitor yet, but this one is switchable.
as in.. 2d.. 3D...2d... 3d..
I feel dizzy... whoah

Bummer tho, since to use the Sharp monitor in 3D you sacrifice half the horizontal resolution. Who wants to see 640x? again? :P

Dont you mean "I want to interact with my pr0n"?
So when you forgot everything you might once have known about thermodynamics, did you get hot (because of loss of intormation)? Energy is conserved, entropy increases all of the time (pretty much...). It is not true that an increase in entropy will result in excess heat (energy). Nor is it true that simply ignoring available information increases entropy.
And if your calculation of 1/3 = 50% is anything to go by, your 50F increase is probably way off anyway (even if the theory was sound)
Entropy is often explained by comparison to disorder or loss of information, but it is neither of these, it is a function of state of any thermodynamic system. And it cannot create heat out of nothing.
Why is anything anything?
This is semi-ontopic, but I wanted to say that Sharp make what are probably the best TFTs out there right now, so when this screen hits the market, it'll probably be a stunner.
Sharp were also the first to produce 16" TFTs (one of which I own) which while double the price of the cheapest 15" displays, have a response rate of *half* what normal TFTs have, sRGB profiling, dual inputs (VGA/DVI), and a 1280x1024 resolution.. compared to the awful 1024 of most smaller TFTs. The 18" Sharp TFTs are pretty much the same, but larger, and oh so sweet. The 16" TFT is 104dpi. With ClearType, that leads to 300dpi (horizontal) goodness on text.
Another thing Sharp has pioneered is 'slim bezel'. Most Sharp TFTs have a bezel of about 1cm, compared to the horrid 3cm+ bezels of most TFTs.
Sharp are the kings of TFT (except, perhaps, IBM who produces those 300dpi dowickeys), and anything they produce has got to be hot.

I wanna see a screenshot of that 3D-effect. Every time nVidia and friends makes a new 3D GFX-Card, we almost drown in screenshots. Sharp could learn something from their marketing dep.

Whoops!
Objects are perceived as the same distance away when light takes the same amount of time to traverse from each of the objects. Therefore you can imagine the world as a series of concentric spheres about your eyes, each sphere representing a "plane" of distance. In order to create the illusion of 3d on a 2d surface, it is required that the light traversal time be increased for those parts of the scene that are to be perceived as "deep". The problem is, while there are ways to make light go slower, the thickness of a sheet of paper (or even a computer monitor) isn't enough space in which to do it.
Therefore, until some fundamental hurdles are overcome, 3d computing is only a pipedream.
Sorry, I had to repost this from the previous version of this story, it was just classic.

"entropy increases all of the time"
In a closed system, DISORDER increases all of the time, no "pretty much" about it. ENTROPY is the subject of the Second Law of Thermodynamics that defines that increase.

For something this precise, the diagram in the link indicates that you have very little leeway as to how far to the left or right you can move your head from the center of the screen. Doesn't sound like a great joy to have to hold your head in some sweet-spot.
Geesh ppl.. ONE bad experience and Sharp goes permanently bad?... I remeber my Sharp MZ720 computer in 1982.. COOOOOOOOOL!.. Neway.. didnt this get /....ed.. a few of days ago?
Heh, I really don't understand how the viewer can see anything of interest, when his eyes are on TOP of his head!
And when you look at their diagram with your head tilted to the right, it looks like an alien under a heat lamp.
Anyone else think the art work ought to be a little better considering they are trying to sell a monitor?
Gamers are used to this, since positional audio relies on the head being in a specific location relative to the speakers and not moving around too much.
shouldn't we explode?
Sweet!

Perhaps someone with experience in what Sony claims is "an older, well-known approach to generating a stereo display" could give us a better idea.
One such method is called lenticular.

FOX used to run these ads that had a little, shitty picture at first, with (?!?) bad sound.. then it expanded to encompass the full glorious resolution and sound of... my regular TV.. to demonstrate the hi-def superiority. Made me laugh every time. People are impressed by HDTV when they see a real one, but how often is that?
Back OT - does anyone know if this Sharp model 3D LCD does that half-brightness' thing when switching to 3D? I remember an earlier prototype used 2 LCD panes to simulate the effect, with the result being that one mode had half the brightness.
If Jesus wants me it knows where to find me.
Since these devices have a "sweet spot" I can see great applications for automotive applications. the passengers are ususally at a constant location (also in airplanes) these screens could be used to effectivly overlay a real picture in 3d or some other navigational data or perhaps something else clever...any other ideas...
Anyone who can play Quake on an LCD monitor is a newbie.

A bubble which I can watch 3d stuff in. Maybe have it mounted on a special table. This would be much truer to 3d, and it would be of dubious value to first-person shooters, 3rd person shooters would be pretty sweet, and strategy games would be absolutely kickass.
As previously mentioned, I *know* that I saw one of these in an arcade years ago. I'm sure somebody should have come up with something better, can anyone find it?
Then things can really sneak up on you.

Though it's looking like that company is pretty much defunct, you'd think Slashdot'd tone down the excitement a few notches, considering that they'd already hyped exactly the same techology.
still no affordable > 21 inch "plain" LCD's that can display high resolutions with no ghosting or color washout... ugh.
I always feel vaguely uncomfortable in situations like these..
Even if I say something insightfull or inteligent, it doens't matter cause I'm an ass.

6 or 7 years ago, my friend got a brand new packard bell computer, and it came bundled with a doomlike/flightsim game called Magic Carpet. The relevant part is that it had a stereo-vision mode, which made all the graphics appear as those magic eye images do. So if you crossed your eyes just right, you'd play with some pretty sweet effects.
Anyone else ever play this one? Is this the same deal as with the LCD monitor in the article? The article was vague (for me) as to what the 3D image would look like.

to developers? They sound as if they are putting effort in making sure that there are apps that support this. It seems like if this technology is really so great it would propagate itself without the extra effort. Just send a sample device to a developer and let the technology speak for itself... right?
Please help! I'm stuck inside my virtual reality headset!
So THAT'S what's taking 3dRealms so long!
I can only guess that you must have been a little kid to have missed out on Virtual Reality. Really, what is today Q3A and UT grew out of the want for better 3D graphics for those systems (I am not saying VR begat Quake, but it did influence the development of 3D engines, etc). HMD's, head tracking, glove input devices, 3/6DOF position sensors, etc.
I have a wierd feeling - I mean, back then (and less so now, but still happenning) a lot of people were developing VR systems AT HOME - using 386/486 machines, Amigas, LCD TVs (for HMDs), potentiometers and wooden arms (for head tracking) and Powergloves to interact with 3D worlds they created (most of the time using Rend386 or other homebrew 3D software).
What has happened? Has all of this knowledge, not to mention the knowledge of the existence of this knowledge, been lost? Heck, I KNOW that can't be the case, my website has a ton of the old stuff on it - I still see new stuff appearing now and then (such as that Linux PowerGlove driver that works great with my modded PG). It seems crazy - but it is almost like you are one of a growing cadre of people who are TOTALLY unaware of this technology - and furthermore of the fact that today one can build a homebrew VR rig ULTRA-CHEAP, given some time, materials, and a little knowledge. Even if everything was bought off-the-shelf, it still would cost less than $5000.00 to do it. Buying used, or building, that cost could easily drop to below $1000.00.
I am wondering if VR isn't undergoing something like the concept of a windowing desktop - I mean, the first such desktop didn't come about until 1969 (or was it 68?), but it took another 15-20 years before it really started to catch on, and another 10 still before it became ubiquitous - perhaps around, oh, say 2015 to 2030 I should expect VR to hit BIG, and it will be NEW and FLASHY!

From the conceptual diagrams it looks like the screen is highly dependent on the position of the viewer, as the parallax barrier forces the left and right images to distinct angles. It looks like a viewer would have to sit very rigid in one spot to get the 3D effect, never mind having several people trying to watch a screen at once. This doesn't look like a goer for home theater applications.
"Nine times out of ten, starting a fire is not the best way to solve the problem." - my wife
This device, called TWISTER, was at the Siggraph 2002 - it consists of a drum made of of panels of LEDs that spin around the viewer standing in the middle. It was created by Kenji Tanaka, et al at Tachi Lab, University of Tokyo. I would imagine such a device could even be built to do full 3D, perhaps by using shutter glasses of some sort synched to the scanning of the LEDs. What would also be cool is to add a head tracker that could tell which direction you are looking in, and only activate an "arc" of panels such that the view went beyond your peripheral vision, but didn't wrap around, lessening the load on the computer driving the system (why display what you can't see?)...
Anyhow, this image was taken by Jerry Isdale, a long-time graphics/VR researcher, who attended the show (sadly, I was unable to attend - can't afford it).
The rest of his report is also interesting, showcasing other 3D and VR technologies presented...

Humans do not see in three dimensions; they see in two dimensions from two different angles. While you do need to be able to control pixels anywhere in the bubble, at any given time you only need to display a single 2D surface, so bandwidth is not the issue. The bubble could accept ordinary OpenGL commands, just ignoring the perspective matrix.
It's all about information. To originate it, to transfer it, to process it. Computer makes a data processing in electronic way - in way that has nothing to do with real optical images. In fact, all images we see are not real - they are some sort of reflections recognized by neural cells in our brains.
Why would I need to display the image optically using unperfect devices (for example LCD), then watch the image using my nonperfect biological eyes, and only after that recognize the "neuralized" imgae in the brains? I want to get the image directly, without any optical hardware. The image was originated electrically - let it stay electrically until my brains will do anything with it. I want to recognize the image right after it's originated and transfered.
How to do that? Very "simple" (smile) - just implant some electrods into neural cells somewhere between my eyes and my brains. Of course it will take some training to get to use it - similar to training we do while we are toddlers.
How would it look like? I come to my head-less PC, connect the cable from my head to TNG-display socket and work!
That's about output. Some similar (with difference of where to implant the cable) should be done about input - no keyboard, no mouse, no joystick - just think what you want from PC and PC will help to imaging what you get.
I think that should be the target for the industry to achieve by the end of the centure :)
Less is more !
Before you run out and try to buy one of these puppies, take a moment to realize that stereo differentiation is just one cue used for depth perception. One of the strongest cues is actually motion parallax. Try closing one eye, then swaying your head from side to side. You can tell which objects are closer to you by their apparent motion.
In order to get some really believable 3D perception out if this monitor, you are going to need some way of tracking head position. So, if you want non-invasive 3D in the future, be prepared to have a camera pointed at your head, and another computer chomping the video stream to compute your point of gaze.
Nothing is as simple as it seems.
I don't really think the 'switching' capability of this thing is really that impressive, considering the fact that all you have to do is throw everything on the same 'plane'... in other words, display the same image for both eyes. Not really much of an accomplishment.
I don't even see how it could not be possible.
autopr0n is like, down and stuff.
The system needs two view points to work. You simply can't take a picture of it, you'd only get the left or right image. Any pictures would have to be mock ups, and no one really wants to see that.
I don't know about you guys, but I think a 3d desktop would be bad-ass. When program windows are stacked on top of one another, the ones in the background shrink a little and and fall away into the distance. Your foreground app would be up front, and everything else would just shrink towards the horizon.... I'd love to see that!
Due to the technology involved, you'd have to sit straight in front of the monitor to see the picture in glorious three dee (correct me if i'm wrong here!).
Now if you were geeky enough to have a twin monitor setup (like i do at work), you would probably have to tweak the monitor angles to allow 3D on both displays. Also, you could not move (strafe) your head around too much, which i do all the time with these two monitors, or you'd lose the effect. Oh, and anybody looking at the display from the side, except from maybe certain angles, would not get three dee. But then, i payed for it, so it's my three dee ;)
On the other hand, since they will probably charge a truckoad of money for a relatively simple solution, few could probably afford two of these puppies.

In fact, it looks like the "top down head" image was ripped of an old dti brochure. We've had one of these things in the lab for 10 or 12 years (it's attached to a x286 luggable). I'm not sure how it's 'revolutionary' or even 'new'.
