Manipulating 3D objects is instinctive with Cubtile.
Cubtile is a cubic device based on IMMERSION’s multi-touch 3D technology.
According to feed-backs from first users, clients see the Cubtile as an innovative alternative for handling virtual objects in a context, enabling any interactive 3D scenario.
Many industries can leverage such new 3D experience. Automotive designers, for sure, and many other ones. Let’s discover more very soon.
Please send us your comments and questions on Cubtile.
Commercial units of Cubtile will soon be available in North America.
You should experience it live next month in Los Angeles at Siggraph Exhibition (Aug 7-9th, 2012)

The 3D CALIFORNIA team
Hi. You may not know me yet, as I just joined 3D California. My name is Joachim, I’m a French intern and I’ll do my best to provide frequently some quality articles about Augmented Reality in this blog for all of you, 3D and AR fans.
So, after two or three years of hype, you sure know what Augmented Reality is. Or at least you have a lot of examples in mind. But AR is both the set of technologies and hardware, and what we do out of it. And we keep creating, discovering, and inventing new gadgets and new ways to use them.
As impressive as all these new applications can seem, there’s no such thing as magic. I’d like to take you on a tour to see a few tricks, explain a few technical points, and help you understand how it works, and this is the aim of the series of articles entitled “A quick peek behind the curtain” that I’ll be writing for you on the next weeks. I’m not (yet) a professional; I’m still learning lots of new things everyday and the content of these articles are the results of personal research, visits, discussions and a few years of great interest toward Augmented Reality, its technologies and applications, but it’s a fast moving world. So there might be a few points that are out-of-date, or not quite precise. Feel free to correct me if I’m wrong. Of course, I’ll do my best to document and source my articles, so that most of what I say can be checked.
Let’s lift that curtain a bit !
Today, I will talk about why the Cyclops from Homer’s Odysseus would not have appreciate James Cameron’s Avatar.
As a huge 3D fan, there’s nothing you appreciate more than this feeling of immersion given by the use of the three dimensions. Of course, today, we can do pretty neat things with a 3D artist and a normal TV or computer screen. And we can see those fantastic models rotate in every direction, just in front of us. But that’s nothing in comparison to what we feel when those models start turning around us. I’m sure that you felt something special when you saw that beast coming right behind your nose. All the trick comes from that obvious fact: unlike Homer’s Cyclops, we have two eyes.
And now for the explanation: our eyes are both able to see. But given that each of them is on one side of the nose (we estimate the distance between the eyes at about 65 millimeters or 2.56 inches), they don’t see exactly the same thing. For objects that are far away, there is no difference (try to watch through the window and close alternatively one eye and the other, and you should see about the same thing). But for objects that are close, this is a different matter (this time, hold a pen a few centimeters in front of you, and close your eyes alternatively again, watching you screen. Depending on which eye is open, the pen is on a completely different location). The left eye sees them on its right, and the right eye sees them on its left. And when the brain gets the 2 images, it’s able to figure out which objects are seen the same way by the two eyes (they are far away) and which objects are different (and thus closer) and estimate their distance.
That said, we still want to get that cool Avatar 3D effect, so… how do we do now? The answer holds in a few words: we simply film with 2 cameras that are distant of about 65 millimeters, and we get 2 different movies: a right eyed one and a left eyed one. And we just have to send the movie to the good eye. Easy to say, isn’t it? There are a few methods for targeting a specific eye with a specific movie, let’s see a few of them.
The anaglyphs :
I bet that you recognize those glasses from, let’s say, the last time you bought cereals. And the images to use with are like that. You know that the colors are combinations of Red, Green and Blue. And when you put a colored filter (like a colored glass or transparent plastic sheet), you only distinguish the other colors. So we keep the red part of the left image, and the blue + green (= cyan) part of the right image, join the 2 images and have you look at it through the glasses. Your left eye has the cyan filtered out, and only sees the red details, and vice versa. ” Et voilà!”. But this long known trick has a problem: you can’t really play with colors anymore, because you use them with stereoscopy.
They are a lot of others techniques that I’ll be explaining in more details next week, including the way Avatar’s 3D was done. Hope you liked that first article. Feel free to give us feedback, reactions, details or simple comments, so that it will get better and better with time!
Have a good week!
Bonus: if you have anaglyph glasses, you can feel again that 3D feeling with the trailer of Avatar in anaglyph 3D

Different website, but all the informations also appear on the Wikipedia article
Surimpose information from computer to visual fied in real time become a reality in Japan. The goal is to improve and enriched the shopper experience. Several firms are testing such devices.
Toppan Printing Co Ltd provide a dedicated terminal, allowing for example to improve signage and items information, or even to locate a store around. It’s very simple : the consumer has just to show his product in front the Terminal cam, which recognize the product package and return a 3D augmented display of the product with its description.
Supplementary application making the link between physical and virtual world : the QR code technology
You can shoot the QR codes with your mobile phone and you have just to show QR at camera (the one of the Toppan dedicated terminal) to get, some samples of associated product.
Other example with Sony Music Communications Inc and Sky&Road Co Ltd, they propose an “interactive show-window”; you have just be on stand in front the terminal (fitted with cam ) and a virtual image (representing a pattern or decoration…) is surimposed on the real one of you.
Finally, with the two previous companies, we note the “Magic mirror” which can be a major innovation in field of clothing.
Imagine you’re wearing a long sleeve shirt and you want to know what you would look like with short sleeves shirt; so you have just to be on stand in front of the mirror and the computer generate a nude pair of arms; we realize easily the scope such applications in clothing area and elsewhere.
the actual application are developped with the AR development kit of Total Immersion.
