Holographic Keypads Float Into View 291

prostoalex writes "The New York Times tells the story of a Connecticut-based company called HoloTouch that is developing input devices that literally "float in the air". The technology will be licensed for information kiosks in New York city. Some other sample applications are available from the company's Web site. HoloTouch already managed to secure the patent on its technology."

        You just can't see a stereoscopic vision allowing you to definitely position the object in three dimensional space. But the eyes use other cues than stereoscopic vision to determine position, cues like parallax and brightness, as well as ocular focus.

          Good question, but that's not the issue. People seem to be believe this company has invented a new type of holographic technology -- they haven't. What they've done is invented a method to accept tactile-less input from a hologram, regardless of the holographic techonology. That's why the images are fakes.

          What this company needs now is a partner who has some good holographic technology in the works.

I'm just pulling this out of my ass, but there must be a way of doing it...

      • You're a useless little puke, aren't you? :) The hard part of this equation is not detecting the fingers interacting with the hologram. The hard part is generating a free-standing hologram without any physical component (like a collimator). They don't give a shred of information as to how they accomplish that heretofore impossible feat, and the obvious photoshop-generated nature of their pictures only throw the whole thing into greater question.

          Actually, if you read the article, it describes how they take a standard film based hologram and mount it on a piece of clear plastic and then put what amounts to an IR grid above it to detect finger placement.

          This is NOT real-time holography, or 'floating in mid-air with no box behind it' holography (as the images on the website show). There is one image of they guys laptop with the device attached.

          Its still a cool idea because it would be completely spill proof and have no mechanical wear. I can see something like this being popular in industrial applications where component wear or material spills could be an issue. And it should be reasonably cheap too, because its basicly a piece of plexiglass with some IR LEDs and sensors.

    Anybody see the lack of tactile feedback as a problem? Holograms are great for unobtrusive displays like in aircraft like the story says, but once you start interacting with it, you would expect some type of feedback.

    Especially, if they plan to use this sort of thing for remote medical procedures. Imagine a doctor trying to perform a delicate surgery, without any sort of sensation of touch whatsoever.

    Maybe they'll come up with force feedback gloves or something.

    • Anybody see the lack of tactile feedback as a problem?

      Only if they fail to combine it with some sort of visual and/or audio feedback -- such as making the number you press blink white and go "bing!" when you touch it.
      • My thought exactly, with one qualification. This will be a great input device for menus and other selection of discrete options, but it will suck for any significant data entry.

        Tactile feedback is great for typing. Having your keys flash and beep each time you touch them, when typing or building up your input with multiple key presses, would get very irritating very quickly.
    • you would expect some type of feedback

      Indeed, but tactile is not the only possible form. Auditory feedback and visual feedback both work, though for touch-typing speeds, visual isn't acceptable...too slow.

      I've used a projection-keyboard system (non-holographic). It takes some getting used to but it's pretty amazing. Expect to see it in cell phones/PDAs within the next 2-3 years.
    • How about a combination of visual and audio feedback? Maybe if the pressed key changes color and/or flashes, and if there's some audio feedback of click .WAV playing at the same time. Granted, it'll be a looooooong time before anybody wants to rely on this tech for intensive data entry, but by then there'll probably better voice recognition anyway.

    • Maybe they'll come up with force feedback gloves or something.

      Man imagine that, a device that displays "keys" to be pressed that have feedback to them. So that there's actual sensation to pressing them.

      We'll call it "keyboard"!!

So the image won't float in the air above the body of the person being operated on, it will float in front of some display case. It won't be visible from all angles

    I can see some advantages to a keyboard you wouldn't have to touch, but I don't think I could use it. The feedback I get by pressing the keys is how I know that I hit the correct one and that I pressed down far enough. The feel of the keyboard is also how I know where to position my hands without looking. I would probably have to look at something like this while I type, which would slow me down drastically.

    With a holgraphic keyboard, you get the ability to customize on the fly, so you can adjust the keyboard position and size for the person.

    But...... it can't be used as a long term replacement for a keyboard. A regular keyboard provides lift to the fingers when releasing the keys, thus reducing the work on the fingers. This cuts down on RSIs.

    Unfortunately they didn't do their homework :(

    From the website:

    HoloTouch, images of keypads can be any size, entirely independent of the size of the hardware.

    (emphasis my own)

    From the patent:

    When a hologram is illuminated by a reconstruction beam, it produces a real image (which appears to be between the plane of the hologram and the viewer) and a virtual image (which appears to be behind the plane of the hologram). [snip] Thus, it is preferred that the holographic image 207 be a real image.

    Quick review of holography: an extremely high resolution film takes pictures of the interference pattern generated when a coherent light beam strikes an object.

    When coherent light of a similar wavelength later shines through this film, the interference patterns cause it to be shined through in exactly the same manner as the original coherent light, up to about half the resolution of the film. Most holographic film is 3000 lines per inch, so the hologram has a "resolution" of about 1500 lines per inch.

    You see an image because the light reaching your eyes through the film is exactly as it would be had the object been in front of your eyes and illuminated by the original beam.

    The light reaching your eyes is coming through the film and then traveling in a straight line from the film to your eyes. You can only see such light if the holograph is directly behind it, because the path of the photons cannot change after it passes through the hologram (disregarding minor lensing effects due to the atmosphere, that is)

    What does this mean? Well if the hologram appears to be one half meter in front of you and the holographic film is one meter in front of you, and the holographic image appears to be 10 cm x 10 cm, then the minimum possible size for the holographic film is 20 cm x 20 cm.

    I don't call that entirely independent; as a matter of fact, it's a pretty simple relationship governed by a version of the inverse square law.

    Oh, an interesting fact about it is if you take a holographic film and cut it in half, because all the information about the image is stored throughout the film, you don't have half a hologram; you have a hologram of the entire object that is half the size of the original. Pretty cool stuff actually.

I have a serious problem with this and here is what it is: The patent system exists in order that inventors can get a temporary monopoly on their invention as incentive to tell the world how it is done, so that humanity as a whole can benefit from it long after it is no longer a viable business for the inventor.

By that logic, I should be able to patent about 100 ideas that I have every day, just because they would be cool if they ever worked, but won't, because I'm not actually going to build it, and nobody else will either, until the patent expires, because I am going to charge ridiculous fees for the use of my valuable intellectual property, which doesn't exist, not only because it is simply an idea that has no physical incarnation, but also because nobody has ever built the damn thing before.

    And if, by some fscked up logic, you are allowed to patent ideas that have no implementation, what's stopping all the movie producers who portrayed things like this in their movies from patenting this or any other idea seen in a futuristic movie. Hey, I got one... How 'bout patenting cyborgs? Hmmm... Good deal.

    • I just figured out how to stop judgement day, once and for all.

      Patent the idea of robots launching nukes at us, destroying us all. When Skynet starts killing us, sue 'em into oblivion for infringing on your IP.

      (OK maybe not once and for all, but for however long patents last)

    Okay, just assuming that this is a case in which they haven't invented anything, and it is actually a good idea [neither of which I feel able to judge], here is a workaround, NOW PUBLIC DOMAIN!

    Instead of making holographic keypads, make use of the double-parabolic-mirror optical illusion. You know the kind, shown in Edmund Scientific, where there are floating coins in the air. That is clearly not a hologram, but it would work just as well.

    If you feel at all inclined to make something, bookmark this reply!

    Here is a summary [alpern.org] of some people who have a real live working invention, not something they just thought up that might be possible one day
  • They're acquiring a patent, huh? Hm. Do TV shows that demonstrate this technology count as Prior Art? They hope not, because "Earth: Final Conflict" had this type of input device since season one.

    I personally disliked the show, but thought their UIs were right-on for a "futuristic" technology.

    Note: I also thought their "Globals" (handheld computers/communications devices) were well designed, too. I had guessed that they accurated predicted what our technological/design curve would end up being.
  • Well, the article says it is being done by the Airforce, on heads up displays, right? If this is so, then yes, it can be done. As to a copyright, well, the HUD thing is prior art, right?

    Just some thoughts

    Right now, the main limiting factor in PDA adoption (IMHO) is size. They're too darned big, they don't fit nicely into my pocket. Perhaps something the size of a credit card would be well protected in my wallet - but then the screen and input devices are too small -

    Hence - this device would be the savior of the PDA industry.

    Then it would give new meaning to the term, "vaporware."

    From their site:
    "To obtain high-resolution photos of HoloTouch in action, visit http://www.holotouch.biz/pressroom.htm."
    The images on that page aren't even cleverly disguised fakes. This is Pixelon [com.com] repackaged. Go to the LED site, http://www.3dtv.tv/ [3dtv.tv] referenced from their licensee's site. We get more creative imagery. Where's a real working product [actuality-systems.com], again?

    It seems that most people do not understand what the article is about (or they haven't read). Most of the comments here are either speculations about the terrible patent system or unreserved admiration of this super-technology. Here is the gist of it all.

    A usual film hologram (like those that have been around since 1940s [holophile.com]) is made and placed somewhere.

    Light shines on the hologram, producing a 3D image (you have seen it many times).

    The image of the keypad is seen in front of the hologram (no, it doesn't float in the air, you have to look at the hologram to see it).

    Infrared sensors (like those in the projection keyboards [slashdot.org]) detect the movement of your fingers.

    The "key-press" is sent to the computer.

    The inventors explain very well what this keyboard is. It is not the keyboard [agwright.com] from Minority Report. It is a keyboard to be used in places where you don't want to actually touch surfaces for one reason [google.com] or another [google.com].

    This is an interesting invention that might prove useful in some areas.

    There is nothing bad about the patent. Although inventors don't need to have a working model to get the patent (for 2 hundreds years already), this company has a working prototype [nytimes.com] (seen at the top of the article in NYT).

    The media overstates the importance of this technology a bit.

    The company has good PR manager.
