Google Handwrite gets better at interpreting your multi-lingual finger scribbles

Source: http://www.engadget.com/2013/01/18/google-handwrite-update/

When Google's Handwrite feature launched this past summer, we welcomed the ability to compose our queries instead of pecking keys. Problem is, Handwrite had a bad habit of confusing our 1's and l's -- and despite the growing size of smartphone screens, it's still difficult to fit written words on them. Well, Big G has solved those problems with the latest Handwrite upgrades. The system now provides alternative interpretations of ambiguous characters so you can choose what's propper, and it lets you write letters on top of one another instead of spelling them out across the width of the screen. Not only that, folks who search using Chinese characters are no longer limited to single-character input. Want to know if it can interpret your chicken scratch? Head on over to Google.com and enable Handwrite under settings on the iOS or Android device of your choosing.

Chrome 25 extends encrypted search to everyone, not just signed-in users

Source: http://www.engadget.com/2013/01/18/chrome-25-ssl-encrypted-search-everyone/

Chrome users with something to hide have heretofore been required to sign in to Google to keep their omnibox searches hidden from prying eyes -- but today's Chrome 25 beta update changes that. Now all searches are automatically encrypted, whether you're signed in or not. It's certainly not the first browser to implement such a security feature -- Firefox 14 switched to HTTPS for all searches last year -- but it's a welcome change all the same. With web voice recognition and security whitelists on the docket as well, the latest version of Chrome is setting up to be quite the must-have, especially for those who want to keep their Justin Bieber search results to themselves.

Metamaterial camera needs no lens, could herald cheaper imaging tech

Source: http://www.engadget.com/2013/01/19/metamaterial-imaging-sensor/

Metamaterials are proving to be quite useful for toying with the electromagnetic spectrum, whether for technology previously thought to be the stuff of science fiction, or for boring real-world applications. Engineers at Duke University have come up something that falls more into the latter category: a metamaterial imaging sensor that doesn't require a lens to generate a picture. The sensor is a flexible copper-plated sheet patterned with small squares that capture various light frequencies all at once, functioning like one big aperture. Add a few circuits with a pinch of software and the sensor-only camera can produce up to ten images per second, but the catch is Duke's only works at microwave frequencies. Microwave imaging is used plenty, however, and due to its flexibility and lack of moving parts, the sensor could be used to build better integrated, cheaper airport scanners and vehicle collision avoidance technology -- making you safer however you choose to travel. Unless you take the train. Then you're on your own.

Researchers Develop a New Material Giving LEDs a Warm Nostalgic Glow

Having spent over a half-century living under the warm glow of incandescent light bulbs, it's understandable that consumers haven't been keen on adopting the cold bluish light emitted by energy-efficient CFL and LED bulbs. But researchers at the University of Georgia have developed a new single phosphor coating that finally lets LEDs produce that warm nostalgic glow we all know and love.

Past efforts to tweak the color of light emitted from a blue LED have involved coating it with a mixture of different phosphors to shift its hue towards the warmer end of the color spectrum. But as the LED heats and cools, its color can vary over time as the different chemicals respond to the temperature changes. So taking a slightly different approach, the University of Georgia researchers have managed to create a single phospor that does the same thing, by combining europium oxide, aluminum oxide, barium oxide, and graphite powders in a vacuum furnace heated to 2,642 degrees Fahrenheit.

The resulting material is able to produce a warm glow when encapsulated around a blue LED, but unfortunately it's not quite ready for primetime just yet. The current manufacturing process is complex and finicky, and the resulting LED bulbs are actually not quite as efficient as what's currently available in stores. But the research certainly has the potential to finally cast LEDs in a better light for consumers. [University of Georgia]

Google experiments with hardware-based authentication, envisions passwordless future

Source: http://www.engadget.com/2013/01/18/google-experiments-with-hardware-based-authentication/

2012 was not a great year for security. From the "epic hack" of Wired's Mat Honan to the breach of Dropbox and the breakdown of barriers at Blizzard (not to mention countless smaller incidents), last year held frequent reminders that what you put online is never truly safe. Google has, in the wake of such public failings, began pushing its two-factor authentication with a pretty heavy hand. But even that system has its short comings, and Mountain V! iew is l ooking for ways to shore up users' accounts. In particular the web giant is exploring hardware authentication options and experimenting with a device called YubiKey -- a USB-based token system. The research will be unveiled in a paper being published later this month in IEEE Security & Privacy Magazine, and includes preliminary work on a protocol for using a hardware device to unlock an online account. If carrying around and jacking in a USB key sounds too cumbersome, fear not. Google is also working on a wireless version of the platform that could be embedded in a cellphone or even a piece of jewelry like a ring. We may never ditch the password entirely, but we can hope.
