Why Can't All Map Apps Be This Clever?

Augmented Reality has mostly found its niche as a way to bring virtual characters to life through a mobile device. But a Japanese developer has found a more clever use. Crossfader's AR-MAPS app syncs Apple or Google Maps to a live video feed from your iPhone's camera, so you can visualize how you're oriented, and easily locate destinations.

Using the device's GPS, compass, and gyroscope, the app automatically switches between a split-screen map/video view of your surroundings, or just a flat map depending on if you're holding your device vertically or horizontally. And not only does it let you search for a specific address or landmark, it uses augmented reality to overlay markers on the video feed so all you need to do is spin around until it highlights your destination. And best of all, it's currently available free of charge on the iTunes App Store, providing yet another alternative to Apple's Maps offering.

Samsung Ativ Smart PC 500T: Don't Expect Any Miracles

Samsung Ativ Smart PC 500T: Don't Expect Any MiraclesSamsung's Ativ Smart PC tablet is supposed to be a tablet-sized tablet that can run all of your desktop apps. It is all that, sort of. But it's also a mix of things that are impressive, tolerable, and totally unacceptable—sometimes all at once.

Let's get this out of the way first: The Ativ is less about Samsung than it is about Intel. This is the first machine to run on Intel's new Atom chips (formerly Clovertrail). Intel is on a warpath to prove it can make power-efficient, lightweight gadgets that perform as well as their ARM-powered counterparts. The Ativ Smart PC, and the Atom Z2760 inside of it, is the tip of that sword.

Performance-wise, things don't feel optimized, at the very least. There is some noticeable video lag in basic apps like Fruit Ninja, which is strange, but it's rare enough to shrug off. Overall, when you're using and switching apps with the Ativ as a simple Windows RT tablet, it's as fast and responsive as anything we've used. But desktop mode complicates that.

Simple desktop apps, like Pidgin or Chrome, run without incident. On its own, that's awesome. The 1.65-pound Ativ isn't tiny, but it's definitely an average-sized tablet, and desktop apps on a machine this size is a big win.

Other tasks, though, can cause serious problems. The machine is totally unusable while it's downloading something in desktop mode, for instance. All apps, Modern or desktop, slow to a crawl, and the touchscreen barely recognizes input. Dragging something around the screen will stutter for a few pixels at a time, lose track of your finger, and then all of a sudden catch up at once. Then the download finishes, or you quit out of the problem tab in Chrome, and everything is snappy again. You can run into that with any computer, but unless you've been using a netbook for the past few years, you'll notice it far more often on the 500T.

Similar things happen when running heavier programs like Photoshop. But that's missing the larger point—you can run Photoshop on this thing! It doesn't feel as snappy as running it on a Core series, and you won't want to multitask too much while doing it, but running the desktop version relatively well is very impressive. That's about the top end of what you're going to want to run on the Ativ 500T, though. While you can stick Steam on there and run it more or less fine, even relatively lightweight games like Trine 2 are graphical impossibilities for the 500T's guts.

The display is another good example of the Atom-based Ativ being impressive on some levels, and very much not on others. It's a bright, well-calibrated 11.6-inch 1366x768 display, which is the norm on 11-inch ultrabooks. It's brighter than the MacBook Air's screen, and text looks about the same from similar distances. It's totally fine, and a little above average. But compare it to other, similarly-sized tablet displays, like the Nexus 10, or the new iPad, or even other convertibles, like the Dell XPS 12, or the Surface, and it's just not up to par. And at $800, that's tough to swallow.

Design and build-wise, this hardware is some of the least impressive we've seen from Samsung in a while. "Plasticky" is thrown around a little too easily at times, but the plastic back plate on the Ativ 500T is so flimsy that pressing on it with any force will actually distort the LCD display you're looking at. It's like the effect of pressing down on a non-glass LCD display. That's unheard of, even in early generation tablets like the Galaxy Tab or TouchPad.

The battery performance varied. When using it strictly as an RT tablet, the 500T was pretty efficient, making it through a whole day. But when using a bunch of browser tabs and apps in desktop mode, it drained a lot faster. The bevy of ports helps—it's got slots for one USB 3.0, a micro-HDMI cable, and a microSD card. The micro-HDMI port is especially nice, since it handles a second display without slowdown, and works like you'd want from an external display on a smaller computer. The only downside about the ports is the kitschy, sorta-hard-to-remove covers over each of them.

More broadly, there are some quibbles to be had with the integration of a full desktop Windows experience into a regular-sized tablet. Things you don't think of much on a mobile device, like the idle time it takes until the device auto-sleeps, comes into play much more for desktop apps than for mobile apps, since they're often performing functions in the middle of getting shut off, and can't continue in a sleep power state.

Additionally, while in tablet mode, the touch keyboard does not immediately pop up when you interact with a text field. You have to manually tap the keyboard. Should you be using the desktop mode as a tablet very often? No, probably not. But it would be nice if it didn't feel like you were 100 percent unwelcome while using it like that.

Of less concern, but probably worth mentioning, is we saw a low of bugs on the first unit we used. Pixels were tearing and breaking on all of the live tiles, and a bug was kicking us out of the password entry box at the login screen and was booting us to the secondary display menu. Weird. We haven't seen these issues on a second unit that Intel sent us, though.

So the Ativ 500T is a compromise. A bunch of compromises, crammed into a sorta-dorky looking tablet. For a lot of you, that's going to mean it's in a No Man's Land of mediocrity—despite a genuinely impressive trick of running desktop apps on this slender little tablet, just not worth it. But the new Atom is a promising, mostly acceptable processor, if you know what you're getting into. For some of you, Intel has delivered exactly what you've been waiting for in a PC/tablet convertible.

Everspin throws first ST-MRAM chips down, launches commercial spin-torque memory era

DNP Everspin

Who says scientific breakthroughs never amount to anything? Everspin has followed up on research developed by IBM, TDK and German researchers years back and released the first commercial spin-torque magnotoresistive RAM (ST-MRAM) onto the market. The technology works by taking advantage of electron "spin" to store data in a magnetic, rather than electronic state, providing non-volatile memory that doesn't wear out. The company said the first chips were about 50 times the cost of flash memory by size, but where a typical NAND module can perform about 800 iOPS, ST-MRAM is capable of 400,000 -- making it ideal for SSD caching and other demanding applications. Everspin has started shipping working samples of the 64MB DIMMS in a DDR3 form factor, saying that future versions will scale to gigabyte capacities and faster speeds -- keeping Moore's Law hurtling inexorably forward. Check the PR after the break for the company's spin on it.

Sony to release XAVC video format SDK to 4K developers

Sony has announced that it'll release an SDK to 4k developers this month for its recently launched XAVC video format used by the new F5 and F55 CineAlta camcorders. The new specification uses MPEG-4 AVC/H.264 video compression, which allows up to 12-bit color depth, 60 fps shooting speed at 4k and 180 fps in HD. So far, fourteen companies including Adobe and Apple have signed on as licensees, and Sony says the format may come to consumer products as well. Details of the program along with an SDK will arrive this month, just in time for a possible Ultra HD onslaught.

Samsung Galaxy Camera review: a 21x compact shooter brought to life by Android

Samsung Galaxy Camera review

There were no heckles, boos or crickets for Samsung's reps back at IFA. But it's fair to say that the atmosphere following its unveiling of the Galaxy Camera was as muted as it was polite. It didn't help that most journalists in that meeting room were there primarily to see the Galaxy Note II, which was undoubtedly the show's headline act. It was also worrisome that Nikon had recently released a half-hearted Android camera of its own -- the Coolpix S800c running on lowly Gingerbread. And finally, some folks in the room -- ourselves included -- may have been put off by Samsung's talk of "convergence," in reference to the fact that the Galaxy Camera has a micro-SIM slot for HSPA+ cellular data. After all, the whole notion of converged hardware has lost the sheen it once had. Hybridized, perhaps. Modular, maybe. But please, not a camera-phablet.

Here's the thing, though: the Galaxy Camera is not a converged device. It's a camera, plain and simple. It just happens to be one that's hooked up (in a multitude of ways) to the glorious world of Android. More specifically, we're looking at full-throttle Jelly Bean sitting astride the same optically stabilized 21x zoom lens and almost half-inch 16-megapixel sensor that have already been deployed in Samsung's WB850F WiFi camera. These are components which far exceed anything you'd find in even the most image-conscious smartphone. If you want to put a label on it, it's probably more meaningful to describe all this as software convergence. The same OS and cloud-connected apps that have so radically transformed phones, tablets and TVs are now also being deployed in a camera -- and there's no reason why they shouldn't be just as invigorating in this new role. At the very least, don't dismiss this device as a curiosity until you've read our take on it.
