Re:HR3D
It's actually better than that. There are quite a few technologies which will interpolate the "in between" views from several cameras (google "Novel View Synthesis"). Don't forget that lightfield capture technologies like the Lytro Camera also exist.
I've seen projection based glasses free 3D systems that are also quite impressive, such as Holografika.
I really do wish this 3D Hate would end...

Holografika.com
Holografika has been doing this for years. Time to catch up MIT...

Re:Its a UX problem.
Glassless 3dtv already exists.

Except it isn't 3D...
With a real 3D display, there are so many things you could do... with stereo, you get exactly what you've been getting all along, that is, the single viewpoint they think you should have, and that's it. Yeah, you'll think you're perceiving depth, but that goes away the moment you move your head and the image doesn't change the way it should.
Because actual 3D isn't just about providing two different images (which is what stereovision does.) It's about providing the two images that match the viewing angle your position and head angle set up relative to the material being viewed.
Me, I'm good with 2D until 3D actually arrives. Stereovision... no thanks.

Poor choice of koolaid.
Inasmuch as these aren't actual 3d displays such as this or this, but simply stereo displays, very limited single-perspective (same as 2d) "flat-image-per-eye" technology from about 1900 or so, it seems somewhat beside the point to complain about entities marketing installation with the word "sync."
The market has already looked at the jug, poured the koolaid in its mouth, and swallowed it entirely on its own. There's little point in claiming they didn't want any koolaid.
It's 3D if the display offers more than one viewing angle, composite or not. Or to put it in a way that even the most uninformed consumer can grasp, if a one-eyed person (or a person with one eye closed) can view the object in the perspectives we expect from the real world, it's actually there to perceive. That's something worth characterizing as 3D display.

3D without glasses
Personally, I find the glasses too uncomfortable - and although the few 3D movies I've watched are a nice experience, they are not THAT convincing.
I think Holografika is on the right track - they would need a lot more funding though. 3D from any angle for any number of people... THAT's a 3D display if you ask me. -
Re:Just an auto stereo screen
This is a bit more then an autostereoscopic screen. Those screens needs you to stand in a sweet point, otherwise the image gets really-really blurred and your head goes off... This screen does not do that. You just stand in front and watch the 3D image from wherever you want to. (Of course there are viewing angle limitations...) In other words, you can actually use this technology as long as you wish. Did you ever wonder why PhilipsWOW and other autostereoscopic screens are not widespread yet, despite being very cheap? Simply because they cause strain to the user after a few dozens of minutes. Have a look on these videos too... http://www.youtube.com/watch?v=28_gL6GdXuU http://www.youtube.com/watch?v=fdjnit-kiFM http://www.youtube.com/watch?v=vyyvfE9Zm7A Or watch the new videos on http://holografika.com/index.php?option=com_hg&secId=9&Itemid=134

Forget article; check website for technical detail
This doesn't work like the usual autostereoscopic 3D monitors. A few seconds in Google lead me to their site: http://holografika.com/index.php?option=com_content&task=view&id=29&Itemid=63 Note the described operation, and also the interesting claim that "There's no contradiction between eye-convergence and focusing"--this is not the case with 3D shutterglasses or normal autostereoscopic monitors.

Re:Isn't it just a multitouch flat panel?
It's not headtracking. One look at their website would have made that obvious: http://holografika.com/index.php?option=com_content&task=view&id=29&Itemid=63

Re:Isn't it just a multitouch flat panel?
It is very different from the standard autostereoscopic 3D monitors. One look at their website would have made that obvious: http://holografika.com/index.php?option=com_content&task=view&id=29&Itemid=63

Well, kinda..
According to the web site this isn't honest-to-goodness holography, but works on similar principles.
HoloVizio is not a purely holographic system that handles an enormous amount of redundant information. It is rather based on holographic geometrical principles with special focus on reconstructing the key elements of spatial vision. The pixels, or rather voxels of the holographic screen emit light beams of different intensity and colour to the various directions. A light-emitting surface composed of these voxels will act as a digital window or hologram and will be able to show 3D scenes undoubtedly being 3D.
So, yeah, it is interesting, but still a lot of unanswered questions. -
Re:Holodeck or "Minority Report"If you were a VC, I would suggest investigating this a lot more - it seems to be more vapourware than something that's ready for prime time. That may be putting it lightly. Their site makes rather grandiose claims, that the screen generates a high-quality, full-color image with full depth-information, viewable from any angle by an unlimited number of viewers (i.e.: it's not just using motion tracking to simulate 3D for the one viewer). If true, this would be hugely significant!
However, their "explanation" of the technology is rather... vague. Once you strip out all the trite market-speak and "trying to sounds scientific" techno-babble, you're only left with a single useful sentence:The pixels, or rather voxels of the holographic screen emit light beams of different intensity and colour to the various directions.
It is indeed true that if you could make a screen where each pixel can not only control color output, but also directional emission, then you could create a true 3D-screen. However they don't explain (nor even hint) at how they accomplish this massive feat.
Considering that holography is fairly mature field, and that people have been trying to create technology like this for some time... I will remain decidedly unconvinced until they present some real evidence that they have working technology. It would also be nice to have some kind of explanation of how they claim it works. I understand the notion of keeping new technology secret, but just saying "holography" is pointlessly vague. It's not like someone is going to be able to reproduce their technology if they just explain the basics of how it works.
On their site they say:Seeing is believing. Computer animations explaining 3D technologies can often be found. The movies above are real camera shots, this is what you would see live on the HoloVizio displays.
(Emphasis in original.) Yes, seeing is believing. However, a recording of a 3D display isn't exactly convincing: it's trivial for the computer to just be motion-tracking the camera.
Unless someone can provide further details, this press release isn't convincing me that a product actually exists. -

Re:Show off that gesture recognition
according to their site the 3D effect works for multiple views. whether or not each viewer sees a different perspective is unclear, but wasn't the Wii hack for a single view?

Re:Just keep your head perfectly still..
Already done. Covered a bit more in my journal. I'm still piqued that the movie studios haven't caught on to this. It would be expensive to film though. You would essentially need to create a working model from live shots, but it's not so far out there. Just that it's much easier to manipulate the markets than offer revolutionary technology that would keep the theaters packed.
