    It all depends on finding a terse and intuitive gesture mechanism through which the interface may be navigated. I think my preferred approach would be to present the nominal view of the user's desktop as though it were the interior of a hemisphere, wherein all of the various windows and widgets reside, as though they were affixed to the interior of this sphere. Then, a simple move of the mouse rotates the sphere along the X and Y axis, and when finally something of interest is in view, you either click or use the scroll wheel on the mouse to zoom in and make it the active window.

    Kind of like a big virtual desktop, only you get to peek at what's over the horizon.

    From the given picture, it doesn't appear that they're doing this though. It seems as though all of the objects have transformation matrices that are independent of one another, and without any common point of reference, which suggests an elaborate interface.

    But as they say, it's a prototype.

    We do need to do something about windows. It's been twenty years already. We should be better than this. Is the answer to display them at funky angles? I'm not sure. But it's nice to see that somebody somewhere is trying, even if the whole exercise is about nothing more than moving Sun's price on the market.
    • I can barely get around when windows are 2D!

      On both my Linux machine and my windows machine I have virtual desktops and I can never remember what I put where. I try to make up some kind of system that where I put code windows on one, terminal windows on the other, etc. but it always breaks down.

      If this idea was combined with the ability to bring certain windows to view with some gesture as parent suggested, this could be a really powerful way to navigate lots of open windows.

Repeat as necessary. I can switch between tasks if needed and have all the context where I left off contained in the single virtual desktop without having to wander around looking for stuff.

    I saw a 3D video display at the CEATEC conference back a few months ago here in Tokyo. Several makers were showing them off, but they really weren't anything to write home about. I guess it was cool enough that they were able to display a 3 dimensional object or scene with only 2 dimensions, but it's hard to see what the practical use of something like that would be outside of "You're my only hope" type messaging.

    Likewise, 3 dimensional computer desktops are not going to be taking over the world anytime soon. It is hard enough teaching people to use the mouse correctly in two dimesions. Trying to wrap people's heads around a 3 dimensional workspace looks to be virtually impossible.

    The video's unrunnable already because their server is no doubt getting hammered. But I looked at the sample screen and the write-up and frankly, I don't get it.

    The more dimensions you've got, the more places things can get lost -- this applies equally for car keys, lost souls, and music files. One of the beauties of a two dimensional windowing environment is it puts everything right up front where you can see it. A three dimensional environment creates the same problems I've already got in my house; things could be anywhere.

    How long will it be before people using this environment spend an hour rummaging around for something they know they left somewhere, but turns out to be hidden behind some other item? It'll be just like today, when you spend two hours looking for you checkbook, wondering if you accidentally threw it out, and finally find it had fallen under your old hiking boots in the closet. I get quite enough 3D at home, thank you. I think I'll pass on using it for my windowing manager.

    Add to this that, in the absence of 3D goggles, everything in 3D is going to appear annoyingly false. And while I bet goggles will be amazing for games and certain specific applications, I don't want my day-to-day working environment to gratuitiously throw in an extra dimension I don't need. It's just one more thing to keep track of. And at the risk of sounding like an old man, the sample screen shot looks like something that would give me a massive headache if I had to deal with it all day.

      You're not exactly right there.

      It's only hard to place things in 3d if there isn't a clear system for it. If you look at the demo video, it looks like the intended use of 3d-ness of the desktop is actually just being able to turn your application windows sideways to sort of file them away. Certainly, windowshades has much the same effect, but this way you can select what you want faster, both because it's a bigger thing to click on, and because you can visually identify your application instead of having to read the title bar.

    • You should watch the video. It certainly looks nice, though how many features you'd actually ever use is another matter entirely. I suspect many people would turn off all the chrome, and use it much as they use window based systems today.

      They have miniature versions of all the running application at about 45 degrees angle from the viewing plane in a row at the bottom of the screen, so there is no chance to lose your windows as you suggested.
    • The more dimensions you've got, the more places things can get lost

      I think we should go back to a 1 dimensional model. None of this fancy 2D directory type stuff to get data lost in :-)

      • Your comment might be a joke, but I actually prefer one-dimensional file-lists. When looking up something on an alphabetical list, it's much easier to read vertically instead of horizontally, with labels left aligned.

        Filemanagers like Nautilus, Konqueror or IE, in icon view, show a lot of icons, from left to right, with centered labels and looking up something is quite hard. Besides, horizontal contiguity means something, but vertical contguity does not (and actually is changed when you resize the window)

    You know, I like Java technology. If it weren't for the existence of Java, we'd never have this push towards writing user space software in higher-level languages that run on virtual machines. As a productivity aid to engineers, I think it's one of the best advances of the past decade.

    However, although Schwartz demo'd some clever technology, it was not very flattering. First of all, it has a little bit of the "me too" syndrome, considering that Mac OS X already has some nice eye candy that uses the same techniques: fast compositing and scaling, to run videos in an icon; translucent windows; windows that easily shift and scale without losing clarity (Expose). Heck, Microsoft demo'd their "me too" six months ago with early images of Longhorn.

    Second, was it really necessary to spend the whole time bashing the "dominant" operating system provider. Believe me, I'm no fan of Microsoft, but this anti-Microsoft schtick of Sun's is becoming tiresome, unflattering, and it's not helping their stock price.

    The problem that nobody developing 3D desktops seems to acknowledge is blatant. A monitor display is two-dimensional. It is suited to displaying two-dimensional artefacts.

    When you try to display something in three dimensions on a monitor, not only does it not really exist, but your brain can't deal with it. Watch computer game novices (and some experts!) try to lean their head around to peek round a corner playing a FPS game. See how quickly most people get motion sick watching someone else play a game. It's all because the visuals are faking 3D and our eyes & brain can't deal.

    A 3D desktop is not going to be a feasible reality until we have a feasible 3D display to draw it on. Only if/when hologram or 3D-projection displays become a reality will there be a useful case for a desktop to match; in the meantime, this just adds unnecessary complexity to the 2D desktop.

    A review is given at the link I have provided, but this program was really the marvel of simplicity. It is only 356 KB (yes k), and truly converts all the files and folders on you computer into a 3D space.

    If you are ready to re-INTERPRET what you normally store in a folder of file, so that it now fits this visual space, it is extrememly powerful.

    For a person just starting off, the novelty of 3Dtop wears off pretty quickly because you easily get lost, and it looks just like eye candy, but if you REinterpret what the folders and files should contain, it becomes a very very powerful cognitive space.

    Please don't flame me if you don't understand what I am saying, but as a last point, I would like to mention that as our cognitive space (displayed in the electronic space on the desktop) has no real correspondence to physical 3D space, it becomes hard to impose "laws" (like physical laws) and hence the electronic space almost becomes infinite, and really disorienting. One way to build laws is to recognize that (in Windows) the Desktop itself is a folder, which contains My Computer, which has the C:\ drive, which has windows, which has Desktop again ... it is this Russian Doll like relationship between two Desktop views that provides the backbone for building the laws that are equivalent of the "physical space" for the electronic and cognitive space ....

    Apparantly the "Looking Glass" demo (running on a little Sony Vaio) was one of the most popular demos at Comdex. I liked the desktop layout as well - very clean and simple, but amazingly flexible.

    I think it's pretty obvious what they've done - just turn each window into a texture map, then project that in a 3D environment. That's why they can flip the windows, have multiple copies etc running very smoothly (3D accelerated), and also why you can do alpha blending very easily, or have the entire backdrop being a 3D projection (eg 360 degree world view.

    This is probably using the OpenGL wrappers in Java... Sun will be feeding the "looking glass" technology into the Java Desktop System over the next 6-12 months. They weren't originally going to be so agressive, but due to the huge interest, they said they decided to accelerate the schedule. One nice side benefit of this becoming a "must have" is that the 3D cards guys will probably get more serious about doing proper, complete OpenGL drivers for Linux (the current situation ain't that great).

    Like some of the others here, I do wonder just how productive it would be, but it didn't seem hard to use at all. It does give Linux (and Unix since it can run on Solaris too) a very nice wow factor - the Sun guys gave it a kinda "who cares about waiting a few years for Longhorn, here's what you can do today!". Will help dispell the bad perception that Linux has for desktop use.

      It could be argued that the current situation "ain't that great"(sic) because the card vendors don't see enough of a commercial market in desktop Linux to warrant the investment required to make proper drivers. For Sun's Java Desktop to change that means that it would have to, out of the gate, start garn

    It does sound like some of you didn't even bother to RTFA. One of the points of the 3d desktop is to make it easier to find your windows. Your not going to lose your windows with this technology.

    I think it also shows that Sun is still trying to innovate, frankly that should be applauded. Besides, it looks way cool!

    It's largely written with Java (proving for once and for all that there's no inherent performance gap for Java applications) and makes good use of the integrated Java support in JDS.

    That tells you nothing about Java performance. The performance critical portions of Java3D and the operating system's 3D drivers are written in C and assembly language. Even JavaScript and VRML manage to render 3D scenes fast.

    At one level it provides a 3D windowing environment for existing X applications (interesting enough in its own right), but at another it introduces the ability to create 3D applications where you interact spatially to explore data. In the demo video (starts a little way in, persist or fast-forward ;-) you can see the CD selector from the screen-shot to the right in action, and I can imagine all the other experimental 3D apps I've enjoyed using (photo gallery browsers, SQL database explorers with 3D visualisation, etc.) finally making it to the real world.

    3D data visualization is an old hat, as are 3D user interfaces and mapping 2D window systems (including X11) onto 3D surfaces. There are even a bunch of open source projects around, including 3dwm.

    What if windows were translucent so you could see the multiple windows you're working on at the same time? What if you could tack a note to yourself right on the Web page you're viewing? What if your CD or movie database became a 3D jukebox, where titles were joined with images to make finding what you want easier than ever?

    Translucent windows have been done many times, as have annotations. 3D representations of physical objects as user interface metaphors have been done numerous times (and those kinds of interfaces generally belong into the Interface Hall of Shame), and "titles" can already be "joined with images" in some MP3 players, including Windows Media Player.

    Sun Microsystems' latest innovations by its Advanced Software Technology Team will make the above scenarios a reality for the desktop of the near future.

    There is nothing wrong with tinkering with old ideas and trying to integrate them into a nice system. But, people shouldn't repeat old mistakes and they should give credit to the people who came before.

    Referring to such tired old ideas as "innovation" either means that Sun is ignorant or that they are deliberately misrepresenting their work.

    I think 3D GUIs may have some good purpose, but the problem is that until now they have mostly been applied to things that just work better in 2D.

    The clearest example of this is exploding menu-style choices from a 2D list that is easy to scan quickly and accurately with your eye into some 3D "infospace."

    Imagine going to a restaurant where, instead of a paper menu of the food options in front of you, all of the waiters in the restaurant, each holding a big sign with the name of one menu item on it, form a big circle around you and you have to turn in your chair around to view each one.

    Restaurants have been around for a long time and I don't know of any that work that way.

    Looking at this, I can't help but wonder, how do they intend to handle the blurriness and uneven pixel distortion that inevitably results from matrix transformations on bitmaps?

    If you're on a mac running panther (like me) you can see this with Expose -- basically, when you take a window and shrink it it *will* look a little blurry -- particularly if the shrinkage is such that the window is only shrunken by a small amount, say, 90% original size -- you don't get a clear mapping of pixels, so you get weirdnesses. That's fine for uses like expose when you're not interacting with a window's widgets (you're only picking the window itself) -- but if I'm to actually work with a transformed window we had better have a display system that really acts in transformed space, rather than simply mapping a 2D bitmap.

    As much as I dislike MS, and as vaporous as Aero is or whatever-its-called-this-week, it seems like MS is investing into some new kind of display mechanism -- and if it really is vector based and all that hoohah then it probably could skip the render-into-a-bitmap phase and instead draw directly into a transformed gl context, sorry , direct3d of course.

    Anyway, I'll happily admit I'm short on technical details. If anybody knows anything enlightening, please, enlighten me. This is a *real* problem. You can't just transform a bitmapped window and expect people to be able to comfortably read it or interact with it.

    Your mind has a contradiction, since it's well-know now in neuroscience that the brain is massively parallel, yet consciousness itself at any point in time is mostly serial and unaware of the great bulk of stuff that is being unconsciously attended to. Yet, consciousness can use parallelism - as when we focus on an issue, then put it on the "back burner," only to come back to it hours or days later and find that we now "suddenly" have a solution. So the "virtual" scope of consciousness extends into areas which are presently unconscious - yet still active, and still ultimately accessible by consciousness.

    Your consciousness is already a bit like a two-dimensional, small window into a large three-dimensional space - which is just what Sun is working up here for your monitor. So you already have in your brain "mechanisms" for navigating in such a situation. And this navigation is largely unconscious - we can choose where to focus our attention, but much of the process of "choosing" what comes to the focus of consciousness is itself unconscious. That doesn't mean it's not active, and not part of our intelligence.

    We may find ourselves strangely at home in the environment Sun is proposing, able to bring to it some of the "instincts" we use for internal regulation of mind.

    What's good about this technology, is that it is just cool/useful enough to use right out of the box with existing OS/WM/applications, but probably does provide a framework to extend and improve programming styles and UI techniques.

    I guess its fair to be critical that much of this wasn't invented by Sun, but it doesn't change the point that its been rolled into an apparently useful package.
