"“Glass is very aware of the user,” he said. “There’s consequences to that, and things to consider and be careful about. But there’s also opportunity for a computer that’s very close to the person.”"
"Google has big hopes for its Glass head-mounted computer, chief among them a desire to make the unit smaller and more comfortable to wear.
Those were just a couple of the goals for a polished version of the device laid out Tuesday by Babak Parviz, the creator of Glass, who is also the director of Google’s “X” special projects division.
“Essentially we’d like to make the technology disappear,” he said during a conference on wearable technology in San Francisco.
“It should be non-intrusive” and as comfortable to wear as regular glasses or a wristwatch, he said.
Shrinking the unit would require advances in optics and photonics, he said. More computing power is also needed to make the device faster at answering people’s questions on the fly, Parviz said.
“We are going to have a lot of fun around the information management aspects of body worn video – let alone the more prosaic problem of how am I going to get this stuff from the field to a central repository with as few moving parts as possible."

"Kidnappings in Mexico have worsened in the last 5 years, sky-rocketing by 371%. So too have the demand for those RFID implants that were said to allow authorities find the victims. Except for one thing: they don't work.
Mexico has a pretty serious kidnapping problem-so serious that there is now a market for a $4,000...Read more
The main problem is that the technology, for a number of reasons, couldn't have worked in the first place. For one, the implants are much too small for a satellite to pick up. And that's without taking into account the barriers the implant's signal would have to overcome—that is, metal, concrete, and the water of the human body. For another, the implants can't be trusted to broadcast a signal without losing its teeny tiny charge.
And even if the police did manage to pick up the signal, there'd be no time to mount a raid to save you. All told, you're probably only about 1% less screwed.
Xega charges people seeking the implant $2,000 up front, with annual fees of $2,000. For their money, implant customers get a radio frequency identification chip implanted into the fatty tissue of the arm.
"The Palo Alto Police Department has recently installed new video systems on dozens of cruisers, replacing the recording systems that were first installed on police vehicles in 2006. In addition to the usual enhancements one can expect with video upgrades -- high-definition video and high-fidelity audio -- the new recording systems have an additional feature: the ability to record and review what happened before an incident even occurs.
Unlike the previously used Mobile In-Car Video System, which included two cameras on the cruiser, the new systems include five. This means new cameras on the cruisers' sides and rearview mirrors, according a report from the police department.
"We've already had a few cases where actions of our officers that would not have been captured on the old system were completely captured on the new one, which allowed us to have a clear view of what went on," said Lt. Zach Perron, the department's public information manager. "That's exactly what we want to have."
The improvement in audio quality is also significant, he said. Audio recordings in the new systems have far more range and can work "through objects," Perron said."

The Art of Flying Your Very Own Drone
Drones are coming to American skies—not just for surveillance or security work, but also for hobbyists. If you want to pilot your own drone, learn the ABCs of UAVs.
"Over a four-month period I learned how to fly three multicopters: a super-simple $300 Parrot AR.Drone 2.0, a $680 DJI Phantom, and a tricked-out, six-rotor $1300 3D Robotics Y6. Multicopters have anywhere from three to eight rotors, are highly maneuverable, and can hover and fly in virtually any direction. These are good starter drones, because they are generally quite controllable and won't disappear over the horizon in a hurry, the way fixed-wing craft tend to do.
But as I found out, multicopter flying is not without its challenges. Things can sometimes go haywire faster than you can react. Plus, piloting one can be a mind-bending exercise in relative positioning. Multicopters are symmetrical, so it's not always obvious which way your drone is "facing." Remote control usually involves either a radio-control unit with dual analog sticks and a dizzying array of switches and buttons (many of which do nothing), or, in the case of the Parrot AR.Drone, an iOS or Android smartphone or tablet with onscreen virtual controls. Regardless, operation can get a little complicated. When your drone flies behind you and you turn around to face it, the directional controls are now the reverse of what they were when it was in front of you—likewise, if you swivel your drone to face a new direction without reorienting your own body, the drone moves sideways relative to you. For this reason, I suggest keeping your first flights low and close by, and that you find a wide, open area to practice in—I used a local dog park. Also, purchase a few extra propellers, because you're going to crash your drone. And that's okay, because repairing your drone is part of the hobby.
In terms of accessibility, the Parrot AR.Drone 2.0 is the newbie's top choice. It is affordable, durable, comes with a battery and an onboard camera, and is controlled via a smartphone. You can even fly it indoors—it comes with a removable hull that protects the rotors from bumps into walls, pets, and people. Takeoff and landing are accomplished with a single button. The AR.Drone has a sonar sensor that keeps it a fixed distance from the ground, and its 720p camera records a video to your tablet or phone as it flies.
I had fun flying it, and my nerdy little toy impressed my nerdy friends. But the limitations surfaced quickly. The standard battery for the model I tested was rated for 1000 milliampere-hours—good for a paltry 12 minutes of air time. The company now sells a 1500-mAhr battery for longer flight times. Also, since the AR.Drone is controlled via Wi-Fi, it is constrained in its range to about 165 feet from the controller. There's plenty of fun to be had within that range, but more sophisticated choppers put it to shame.
For instance, the Phantom, a ready-to-fly quadrotor from DJI, has a range of almost 1000 feet from the controller. But I wouldn't suggest sending it that far afield—at any distance greater than 500 feet, the drone becomes a coin-size white blob against the clouds. The Phantom is also fast, with a top speed of more than 20 mph—although that kind of hot-dogging will chew through a 2200-mAhr battery (which is not included) in 10 to 15 minutes.
The quadrotor also uses a GPS sensor and digital compass to do away with the orientation problem that plagues most multicopters. Phantom has two Intelligent Orientation Control settings that normalize its forward motion regardless of which way the drone is facing. One IOC setting fixes the Phantom to a grid, which still reverses the controls if you fly it behind you. The other setting fixes the craft to a radius around its launch point; forward motion moves it away from you, reverse brings it back. I found this massively useful once I attached a GoPro to the Phantom's camera mount. I could then steer the camera in any direction yet still fly the aircraft relative to my own postion. It was like having a helicopter cameraman at my disposal for home movies. Now I have tons of aerial footage of my kids playing with the neighborhood dogs in the park, and a few high-altitude pans that give a view of my entire town.
On the upper end of the (or, at least, my) cost-and-complexity curve is the 3D Robotics Y6 hexacopter, using the APM:Copter software platform, which was the last and most ambitious drone I tried. You can build this three-arm, six-rotor craft yourself for $400 to $600 in parts (depending on the options you select), or you can have 3D Robotics build it for you for $700 to $1300. Fully tricked out, a 3D Robotics multicopter can be flown manually with a remote control, or it can do autonomous waypoint navigation. It can be accessorized with a wireless-telemetry kit that communicates with your laptop and a first-person-view camera that broadcasts back to a screen or video goggles. And it can also support a servo-driven tilting gimbal for real-time control of a second video camera. The idea is that you guide the aircraft with the low-res broadcast camera and record with a hi-def camera on the gimbal. Its six motors make the Y6 a strong beast, capable of lifting a heavy payload—some of which is its own large battery (the company suggests at least 4200 mAhr). The drone can also survive one or more motor failures while maintaining flight."
"Imagine you’re walking around the British Library. Suddenly, your smartphone beeps at you. A library app is alerting you to the resources around you. You ask the app to search for a specific book. The app tells you where to go to find it. The smartphone goes to sleep. You reach the suggested reading room. The smartphone wakes up. The app tells you which shelf the book is on, posts up its publication details and reviews, and informs you about related events happening in the library."
