A Big Step Forward In Air Display and Interface Tech 65

Posted by Soulskill from the wave-your-hands-in-the-air-like-you-just-don't-care dept.
wjcofkc writes "Interactive displays projected into the air in the spirit of Iron Man have been heralded as the next step in visual technology. Yet many obstacles remain. According to Russian designer Max Kamanin, creator of Displair, many the problems have now been largely cracked. With this attempt at refining the technology, the image is created inside a layer of dry fog which is composed of ultra-fine water droplets so small they lack moisture. Three-dimensional projections are then created using infrared sensors. The projected screen currently responds intuitively to 1,500 hand movements, many of which are similar to those used on mobile devices, such as pinch and zoom. The most immediate applications include advertising and medicine, with the latter offering a more hygienic alternative to touchscreens. The most immediate objection from home and office computer users is that they don't want to be waving their hands around all day, and while such questions as 'What happens when I turn on a fan?' are not answered here, just imagine a future with a projected keyboard and trackpad that use puff-air haptic feedback with the option of reaching right into the screen whenever it applies to the application at hand — and applications that take advantage of such a technology would no doubt come along. Better yet, imagine for yourself in the comments. As always, pictures speak a thousand words, so don't neglect the articles gallery."

    Seems like the obvious application.

    • It's nice that yo can reach in, but not that nice since it is lacking moisture :-(
    • Sticking your fingers (or other objects) into the stream of water droplets means it cannot move to "catch" the rest of the display (see the article gallery), much like standing between a projector and the screen. So every time you go to "touch" anything part of it disappears, doesn't sound ideal for porn. :P

    ...as described in a summary so concise it lacks sense.

  • The porn industry will be at the forefront of this technology.

    Having said that, really, it will be Google and the *rest* of the targeted advertising industry whores that will be pushing this technology, it will *not* be for the "benefit of mankind", it will be a "delivery system" for paid content.

    And, it will be yet another way to exit reality and live in an imaginary world - in your mom's basement

  • You think touchscreens are bad for haptic feedback? What happens when you don't even get the impact against the screen as feedback that you've actually pressed something?

    I'll answer my own question - this is focused on data consumption, not data production, to an even greater degree than touchscreens are; or for situations where an alternative input method will be used (voice, perhaps? I can't envision a mouse+keyboard being used with this)

    There are niches for this, obviously, but I definitely don't think i

    • I suspect that there are not niches for this. The maximum opacity you can achieve is going to be very low, so while you can vaguely see an image (or see one moderately well with a completely dark background an no ambient light), it's still going to fully suck as a display technology.

      • I've found that almost anything imaginable has a niche, it's just a question of whether the niche is able to afford the technology and development thereof.

        You just have to figure out situations where the weaknesses become strengths. For instance, translucent displays would be essential for an automotive or aircraft HUD. Or perhaps have a transparent layer on top of a traditional display, for a two-layer effect.

  • Is it just me, or does it seem pointless to put more technology into an interface than can come from whatever is interfaced with?
  • It sounds like a clumsy and problem-prone technology to me, and I predict it won't get past the proof-of-concept stage of development.

    • Yeah it probably will go nowhere. But maybe if they can get it working, it could conceivably replace touchscreens at ATMs and booths that users interface with for a short amount of time doing simple stuff like selecting YES or NO.

      I predict the mouse and keyboard will never be replaced for any serious work until direct brain implants can point the cursor precisely where the user is thinking.

        TFA describes it in a way that makes sense even if it's technically inaccurate:

        The water drops are so tiny they don't have any moisture in them; you can test it on paper or your glasses -- your piece of paper will remain dry and your glasses won't steam up.

        More accurately: The water drops are so tiny they won't moisten things they contact.

    Projection onto streams of water is well known. Here are some examples. [jcdecaux-oneworld.com] It's used to create big-screen effects outdoors, usually for PR purposes. You usually get big, but fuzzy, images, because the water screen isn't flat enough. Huge light levels are required, so it takes expensive projectors. Indoors, I've seen it done in a doorway, and you could walk through the image, getting slightly wet.

    Until somebody figures out how to make a curtain of mist/water/some gas or liquid stay very flat, this isn't going to be more than an advertising gimmick.

      It's a party trick, nothing else. You can't do much useful work with it because the display is transparent, meaning the background is whatever distracting crap you have back there.

      Look at it this way. We have been able to print on transparent plastic sheets for decades but no-one prefers them to paper because they are only useful when projected against a large white screen.

Every other year, a company will out their 'WOW Revolutionary!' desktop fog display with mid-air 'touch' sensing, then disappear after nobody buys it. I've yet to see anyone actually buy one of the things from the many start-ups that have produced them. This one in particular appears to have nothing to separate it from the string of flops before it.
