Hands on: 18 hours with Google Glass

Today is my first full day as a cyborg.

I’ve spent the past 18 or so hours wearing Google Glass -- the Internet giant’s vision of an always-on, digitally connected future, disguised as a pair of glassless eyeglasses.

Looking past the double-takes and outright stares from everyone looking at me, it’s easy to see the potential of this crazy gizmo. But for now, well, it’s weird being one of the borg.

Glass is a lopsided yet oddly comfortable hunk of plastic, silicon and titanium. The brains of my device were housed in two hunks of gray plastic, all on the right side (and no, there’s currently no option to swap sides). Google has versions in a variety of colors, including a gorgeous bright orange. If you’re going to call attention to yourself, may as well do it in style.

At the back is a battery and a tiny speaker that rests against your head, and uses the bones in your skull to amplify its output. The front contains the camera, processor and a tiny display screen -- your interface to the world of Google.

I picked mine up from Google’s temporary Glass office in New York. And after a 90-minute walkthrough with several “Glass guides,” I was ready to set out in the world.

I found using Glass to be remarkably intuitive and straightforward. Others who tried it had mixed luck, however, which mainly revealed an eagerness to play around without knowing what exactly to do. The lesson: Read the directions.

Tap the touch-sensitive temple piece or simply tilt your head up and the screen activates, displaying the time and two words: “Ok Glass.” Speak them aloud and the voice-activated device gives you a menu with a few simple options: Google, take a picture, record a video, get directions, send a message, make a call, hang out.

Ask the device to Google something and, thanks to a Bluetooth link to your smartphone or the built-in Wi-Fi, it will search the Web almost immediately. I tried Googling the length of the Golden Gate bridge (8,980 feet), how to say “I love you” in Japanese (“Watashi wa anata o aishite”), and checking the weather (“No, it isn’t raining in New York, the weather is 58 and clear”).

The future is a robotic voice literally telling me to skip the raincoat, apparently.

Pictures with Glass are reasonably good; it has a 5 megapixel camera, comparable to that of a newish smartphone. That’s not the greatest quality, but it works. I immediately found myself wanting to edit images, crop out the backgrounds and boost the colors. You can do that all on Google+, of course, but there’s little interface directly through Glass itself.

The real charm of Glass comes in sharing, however, not touching your temples. Glass integrates deeply with Google+, which you’re probably a member of already, like it or not. It’s no Facebook, sure, but it does have tens of millions of users.

Using the simple MyGlass smartphone app, you can configure the Google+ sharing features on Glass: Which of your contacts you want ready access to, which groups you want to share videos and pictures to, and so on. For what it’s worth, Google+ actually does social networking better than Facebook in some ways, and sharing pics with groups and individuals is as easy as taking them.

On the other hand, social networking is both a Glass strength and its Achilles Heel: Everyone I saw while wearing Glass stared, then eventually asked me if I was recording them. Are we live right now? Is this online?

For the record, no, Glass is not violating your privacy. No, it is not surreptitiously recording you. No, it does not do face recognition. No, I am not seeing through your clothing.

While Google’s wild invention does raise those questions, the device is designed to skirt them all: To start recording a video or snap a shot, you need to actively turn it on. And there’s no red light on the front to indicate activity, but whoever you’re speaking with should be able to see the active screen.

And Google told me face recognition would require some processing power that’s simply out of the question, at least for now.

That said, what it does do is tantalize. Want directions? There they are. Want to share a picture of your trip? Done. Need a fact to wow a dinner party? There it is. 

Just don’t wear Glass during the dinner party. At least, that’s what my wife says.

Video appears to show world's most powerful rifle in hands of Syrian rebels

  • AS50pic.jpg

    A British special forces member used the AS-50 to kill to Taliban fighters from more than a mile and a half away.

New YouTube video from the Syrian battlefield shows rebels firing the same high-powered sniper rifle favored by U.S. Navy SEALs, leaving some experts wondering who the ragtag army of insurgents might train the guns on in the future.

The British-made AS-50, accurate from a distance of 20 football fields, is made for British Special Forces and has been used by Navy SEALs. Video showing Syrian rebels, who are aligned with Al Qaeda, firing the guns and shouting “Alahu akbar,” has also raised questions about who is supplying such devastating hardware.

“The video, showing jihadist rebels of the 'Descendents of the Prophet Brigade' firing one of the world's most effective sniper rifles, should be cause for alarm," said David Reaboi, of the Washington-based Center for Security Policy. "We don't know who has been supplying this group (or the myriad others) with these weapons but, given the jihadist ideology of these groups, it's only a matter of time until they're turned on Americans or our allies and interests.”

The gun set a reported world record when a member of the British Household Cavalry in Afghanistan’s Helmand province killed two members of the Taliban with successive bullets over a recorded distance of more than 1.5 miles, though the record is disputed.

The Free Syrian Army has been receiving weapons from Qatar, Saudi Arabia, and Turkey - all close allies of the U.S. But the U.S. has repeatedly stated that it has sent no weapons to the opposition forces.

"... given the jihadist ideology of these groups, it's only a matter of time until they're turned on Americans or our allies and interests.”

- David Reaboi, Center for Security Policy

The U.S. State Department has acknowledged directly providing $385 million support to the Syrian people, including “emergency medical care and medical supplies, food aid, and winterization supplies like blankets and heaters for those affected by the crisis.” The site also reports that “over 4,000 major pieces of equipment have been provided, mostly to Damascus, Aleppo, and other areas with significant opposition presence, including communications and computer equipment, as well as generators.”

Experts said it could prove impossible to determine where the rebels got AS-50s and how many they have.

The sniper rifle, manufactured by Accuracy International – which sells arms to the Turkish and Saudi Arabian militaries - has a fearsome reputation. It has been used in various theaters of war in recent years by many elite forces, including both the SEALs and British Special Forces.

“I know from first-hand experience how revered the AI product is, even in the States, where traditionally U.S. producers are favored,” a British Army sniping instructor told Wired in 2011.

Call of Duty, a warfare game that in 2009 sold more than 7 million copies in just one day, seemingly endorsed the already lofty reputation of the AS-50 by featuring the weapon in one of its many urban combat simulations, giving the sniper rifle something of an iconic following amongst players of the record-breaking video feature.

The Free Syrian Army has recently made significant territorial gains against government forces in the two-year-old bloody civil war that in March saw its worst ever body count, with independent monitors determining at least 6,000 people were killed.

The gun costs about $10,000, according to Reaboi, and each one could be around long after the war in Syria ends.

"We're unsure of how many they have," Reaboi said. "Equally troubling, of course, is the training ground of the Syrian civil war itself; like the conflict in the Balkans, Iraq, and Afghanistan, we will be facing tested veteran jihadist fighters who don't just leave the war when the one battle is over. I'm afraid we or our allies will have to face them shortly, and with exceedingly lethal weapons."

Especially concerned is Israel, which shares an increasingly uneasy border with Syria in the Golan Heights.

With the Free Syrian Army increasingly dominated by more radical Jihadist elements such as the Al Qaeda-associated Al Nusra Front (Jabhat al-Nusra), concern is growing that it won’t be too long before battle-hardened Islamist fighters as well as mercenaries from around the globe who have joined the fight against Assad, turn their attentions towards Israel. In their experienced hands even a far from easy-to-use weapon such as the AS-50 would be indeed be lethal.

Israel Defense Forces spokesman Capt. Eytan Buchman told FoxNews.com that the IDF is keeping a close eye on all forms of weaponry being used in the neighboring conflict.

“The Israeli security forces are very closely tracking developments inside of Syria in order to isolate and identify any potential threat to Israeli security” Buchman said.
