Windows tablet OS preview coming next week?

We've heard an awful lot about a Windows tablet OS this past year, with stirrings of a 2012 launch -- heck, even Steve Ballmer's fanned the flames of speculation -- and now the rumor mill's been set in motion with word of an impending preview expected next week. According to Bloomberg, three sources have confirmed Microsoft's plan to flaunt the much-anticipated UI, possibly at upcoming appearances at AllThingsD and Computex. The showcase is supposedly set to run the touchscreen-enabled software on a Tegra-equipped machine. We'd previously reported on stirrings of a June demo. Considering all the evidence that's stacked up over the past few months, we'd say 2012 is looking like a rather practical target.

KDDI's Swing navigation system helps you find your way around a store, avoid human interaction

GPS can help you get to your favorite bookstore, but once you're there, it probably won't find that Thomas Pynchon book you're looking for. That's where KDDI's Swing navigation system comes in. Taking its cue from Nokia's Kamppi and NAVTEQ's Destination Maps services, the prototype is designed to help smartphone users find their way around malls, restaurants or any other indoor space, using only a red arrow as their compass. Just choose the section of the store you're looking for, wave your phone in a circle and KDDI's app will use a system of pre-installed sensors to find your location, before pointing you in the right direction. Seems intuitive enough, but Swing's success will ultimately depend upon how many people and retail outlets decide to adopt it. Swing past the break for a demo video.

Sony's SmartAR demoed live, raises the bar for augmented reality (video)

Remember Sony's SmartAR? The markerless AR technology that promises reality augmentation without the need for unsightly tattoos? It's back again, showing itself once more after an all-too-brief 48 hour layoff. A new live-demo shows Sony's markerless object recognition system focusing on posters, tables, books, and coffee cups in lieu of the traditional AR card -- allowing it recognize multiple objects at once. Focusing on objects rather than markers allow augmented entities to interact more naturally with their environment. For instance, bouncing AR balls plummet off the edge of a table, and realistically ricochet off of a book placed in their path. Objects don't even need to remain on screen, as demonstrated by an AR pop-up menu that remained viewable even after the object-marker that spawned it left the viewer's field of vision. Sony seems to have built the groundwork of an augmented reality system that might actually be useful -- pair this up with a set of swank AR glasses (or better yet, holographic AR glasses), and we'll have a vision of the future we can really look forward to.

AT&T demos speedy LTE, calls 28.8Mbps downloads realistic for real people

GigaOM got to peek inside inside AT&T's Foundry innovation center in Texas this week, and the tour came with a special treat -- a first glimpse at how AT&T's upcoming LTE network might perform when the carrier flips the switch later this year. Where Verizon's existing network promises download speeds of between 5 and 12 megabits per second (though we've gotten far better and worse in practice), the publication witnessed a connection with 28.87Mbps download and 10.4Mbps upload speeds, using a MIMO antenna passing bits through both 700MHz and AWS frequencies. "But," you protest, "isn't LTE capable of more?" Sure, but an AT&T executive told the publication that these were meant to be real-world numbers. Still, considering all the factors and where the test was held, it's probably best to break out the table salt for now.
