DemoFall 2011: An App for Augmenting Reality

This latest platform for augmented reality looks like it's ready for prime time.

2 min read

I admit it; I’m a bit of a sucker for augmented reality. There’s just something magical about the idea of ordinary objects coming to life.

So when Autonomy (a company that came out of Cambridge University in 1996 and was purchased by HP last month) demonstrated its Aurasma 3D-I at DemoFall 2011 in Santa Clara this week, I expected to find it interesting. I didn’t expect to find it so slick (though with just a quick look it was hard to tell if it really is amazing technology, or just a series of well-done demos). But other consumer-targeted augmented reality applications I’ve seen to date, even ones I've liked, have been a bit cartoony, or didn’t seem to align themselves all that well with the reality they were augmenting. Part of the problem is that doing image recognition and simultaneously generating realistic three-dimensional graphics takes a lot of computing power, more than, until recently, most people walked around with on a daily basis.

But Aurasma’s team thinks that plenty of people now are indeed carrying around enough computing power, at least if they have iPad2, iPhone4, or Advanced Android devices. Enough that Lynch thinks it makes sense to build an augmented reality platform for those devices. And with years of experience in dealing with sorting through unstructured information, like images and videos, Autonomy had that part of the problem already solved. That’s why, the company says, it’s image overlays are positioned more precisely than those of its competitors.

The basic Aurasma technology has been available for several months, though it was released quietly. The version launched at Demo tracks 3D motion as well as static scenes, letting the user interact with the virtual images.

“We are at the dawn of the age of visual browsing,” said Aurasma’s Matt Mills, admitting that we’d look back on the crudeness of the technology, but that it’s still pretty cool. “It’s sort of like where television was in the 40s,” he said.

The Aurasma app is available free for iPhone, iPad, and Android—it lets you play with building your own versions of augmented reality and share them. But this is just play—it’s likely to become more useful when embraced by companies. It could, for example, mean a quick sunset for QR codes—publications, labels, and posters won’t need to devote space to a code when the image itself can trigger interactivity.

Digging Into the New QD-OLED TVs

Formerly rival technologies have come together in Samsung displays

Sony's A95K televisions incorporate Samsung's new QD-OLED display technology.

Televisions and computer monitors with QD-OLED displays are now on store shelves. The image quality is—as expected—impressive, with amazing black levels, wide viewing angles, a broad color gamut, and high brightness. The products include:

All these products use display panels manufactured by Samsung but have their own unique display assembly, operating system, and electronics.

I took apart a 55-inch Samsung S95B to learn just how these new displays are put together (destroying it in the process). I found an extremely thin OLED backplane that generates blue light with an equally thin QD color-converting structure that completes the optical stack. I used a UV light source, a microscope, and a spectrometer to learn a lot about how these displays work.
