Apple is reportedly working on a way for iPhones to detect car crashes and auto-dial 911
Your iPhone might have a new capability as soon as next year: detecting a car accident and automatically dialing 911.
Scientists used phone accelerometer data to predict personality traits
Our phones contain a disturbing amount of information about us. While calls, messages, app usage and location logs have all been used to profile users, phone accelerometers contain key information, too. Researchers from the Royal Melbourne Institute of Technology (RMIT) University used the tiny sensors that track phone movement for things like step-counting to predict five key personality traits.
Quantum 'compass' promises navigation without using GPS
GPS is vital to modern navigation, but it's extremely fragile. Never mind coverage -- if a satellite fails or there's a jamming attack, it quickly becomes useless. Scientists may have a much more robust answer, though. Scientists have demonstrated a "commercially viable" quantum accelerometer that could provide navigation without GPS or other satellite technology. The device uses lasers to cool atoms to extremely low temperatures, and then measures the quantum wave properties of those atoms as they respond to acceleration.
Coord's new app will help catalog curb rules on city streets
How often have you stared at a curb, unable to decipher whether you're allowed to leave your car there or not because the parking signs seem completely contradictory? That's just the kind of problem Coord is looking to solve. The company announced that its Surveyor system is now available for anyone to use in the US and Canada. It's aimed at organizations that are surveying American cities; the goal is to catalog as many curbs as possible and store the information in a digital database.
NASA will resume testing its Hubble successor this month
One of NASA's biggest victories last year was the $8.7 billion James Webb Space Telescope's completion. And now the aeronautics agency is set to resume vibration testing for the instrument. These tests aim to replicate the conditions it will encounter before lift-off to "ensure that functionality is not impaired by severe launch and landing environments," according to NASA.
Tiny accelerometer adds motion detection to clothes and cheap phones
Imagine a shirt or pants that can detect movement and tell you if that golf swing was weak or that jump shot was a bit lacking. That's the biggest goal of a company called mCube: to have its new and really tiny accelerometer embedded in clothing, though it could obviously be used for sports bands and other devices, as well. At just one millimeter across, the new motion detector measures but less than half of traditional ones. More importantly, it combines the accelerometer component that detects movement and the other that processes signals and data gathered by the first one, which are typically separate. This allows the chip to be power efficient, cheaper and -- according to mCube, at least -- more accurate than alternatives. mCube even believes that the device is effective enough to provide motion detection for super cheap phones without gyroscopes. While the company hasn't announced which devices will carry the product, we'll likely come across one of 'em soon enough, as mCube has already shipped 70 million units to China.
Violinist fiddles with a smart bow to help his brain surgery
It's common for brain surgery patients to stay awake. That's how surgeons know everything is going smoothly, after all. When concert violinist Roger Frisch started suffering from tremors that are only a problem when he's playing, however, Mayo Clinic doctors had to resort to some rather unusual technology to find out if they were installing the necessary brain pacemaker correctly. The surgical crew gave Frisch a bow equipped with a motion-tracking sensor and asked him to fiddle during the operation; the team knew it had electrodes in the right spot when the musician's performance was steady.
Daily iPhone App: House of the Dead Overkill - The Lost Reels is gross but innovative
There are some really excellent apps arriving on the App Store tonight (including Firaxis' great Haunted Hollow), but before we tackle that new crop, I did want to mention this app, released last week by Sega. House of the Dead, if you're not aware, is an arcade shooting game, where you take on a whole haunted house full of zombies and demons with a light gun (and usually a friend, if you're playing in an arcade with quarters). House of the Dead: Overkill was a version of the game that came to Nintendo's Wii system a little while back, and this version, sub-subtitled The Lost Reels, is a revamp of that game, made specifically for iOS devices. Now, this game is gross, and if you've not into gory zombies and bad guys (and girls), then you probably won't get much out of this -- like I said, stay tuned for Haunted Hollow and a few other big releases tonight. But the main reason I wanted to mention this one is that it has one of the best control schemes for a first-person shooter on the App Store I've ever seen. Most FPS games don't end up quite making the jump over to a touchscreen interface without stumbling. There's two routes devs have gone so far: Either they just go all-in on clumsy and not-so-precise virtual controls, or they try something really nuts (Zynga's The Drowning and Industrial Toys' Morning Star are two upcoming FPSes with innovative control schemes). House of the Dead does have a pretty lame virtual control scheme, if you want to try things that way, but the game also has an accelerator-based control scheme, and that one's really fun. You tilt your iDevice around to guide your target, tap to fire, and the whole thing actually feels very intuitive. It's one of the best ways to play a game like this I've ever seen implemented on iOS. Unfortunately, the rest of the game is kind of a mess. To stay under the download size limit, Sega has cut off a lot of the in-game dialogue and cutscenes that made the original Overkill as charming as it was, and while the game costs $4.99, you actually have to buy extra levels and content via in-app purchase -- why Sega chose to do these things the way they did, I have no idea. Honestly, I can't really recommend this one at full price, though it's worth a try for a buck or two. All that said, however, that control scheme is very impressive. If someone can lift that scheme out of this game and put it in a game worth playing, I'd really appreciate that. House of the Dead: Overkill: The Lost Reels is available right now.
Sony preps extra-low power mobile GPS chips, draws on motion sensors for help
Many of us can vouch for smartphone navigation being something of a battery hog. Sony would like us to navigate relatively guilt-free: its D5600 and flash-equipped D5601 chips chew no more than 10mW of power for everything they do. Most of their peers demand more than that just for the RF side of the equation, Sony says. They also won't lean on outside help for their location fix. Both chips talk to GPS, GLONASS and similar systems, but they further share the increasingly common ability to use an accelerometer, gyroscope and magnetometer to get a more reliable position lock. Don't expect thrifty GPS just yet, when Sony ships the basic D5600 in June and D5601 in September; that doesn't even include the time spent to build a phone or tablet around either of the new parts. We'll be patient if they reduce that anxiety over battery life whenever we're getting directions.
New in-car GPS tech uses motion sensors for accurate, autonomous city driving
In-car GPS developers have long had to wrestle with the urban canyon effect that blocks or bounces signals downtown: they often have to make best guesses for accuracy when they can't count on cellular or WiFi triangulation to pick up the slack, like a smartphone would. The Universidad Carlos III de Madrid has nonetheless found a way to borrow a page from mobile devices to get that accuracy back. By supplementing the GPS data with accelerometers and gyroscopes, researchers can use direction changes and speed to fill in the blanks, improving accuracy from a crude-at-best 49 feet to between 3 and 7 feet. The University's creation doesn't just minimize the chance of a wrong turn; it could be key to intelligent or driverless cars that have to perform sudden maneuvers all on their own. While the enhanced system is just a prototype without a commercialization schedule, it already slots into just about any car, including the University's own intelligent car prototype (not pictured here). We may no longer have to lump car GPS units into the same "close is good enough" category as horseshoes and hand grenades. [Image credit: Steve Jurvetson, Flickr]
DropTag tells phones when packages are bruised before they're opened (video)
Many of us have had the misfortune of receiving a package that has been roughhoused in transit, and we might not have even realized it until we burrowed through the cardboard and tape. Cambridge Consultants' upcoming DropTag might just serve as the insurance we need. The badge can detect a drop or other violent motion, like earlier sensors, but carries Bluetooth 4.0 to transmit data and alerts in real-time to a mobile app, whether it's on the courier's smartphone or a tablet at home. As one watch-grade battery could power the sensor for weeks, we could know whether the box took a tumble at the warehouse or at the door -- a help not just for customers wanting their items intact, but for companies that can avoid delivering already-broken goods. At less than $2 in raw costs, DropTags would be cheap enough to slap on many packages. We just need Cambridge to line up clients to make this a reality and, just possibly, prevent a few overly hasty couriers from long-bombing our orders.
Xsens teases wearable 3D body sensors that won't cost, will track an arm and a leg (video)
When we think of full-body motion capture, we most often associate it with movie-grade equipment that demands a dedicated room, odd-looking suits and a corporate bank account to finance it all. Xsens hints that we may not have to rent a professional studio (or stand in front of a Kinect) to get complete body tracking for personal use. It's planning to show a wearable, 3D-capable tracking system at CES that uses "consumer grade" MEMS sensors to monitor joint positions and movement -- in other words, the kind of technology that might go into a phone's accelerometer, just strapped to our arms and legs. Further details are scarce, although Xsens is pressing for uses in everything from fitness to gaming. We'd like to see partners line up so that there's a product we can buy in a store. Until then, we'll have to make do with the company's skateboard-dominated teaser clip, which you can find after the break.
Nikon patent would perfect the art of camera tossing, protect us from our folly
If you're one of the more daring (or foolhardy) photographers out there, you've tried camera tossing: hurling your camera into the air in the hopes that a timed shot will catch either a unique perspective or an artistic spin. Nikon might not want to stop those shooters from throwing caution to the wind, but its recently published Japanese patent would at least keep those throws to a minimum. Cameras based on the patent could use a built-in accelerometer not just for timing the shot, but to brace for a fall by covering the lens and retracting its barrel on the way down. In theory, the photographer gets a perfect aerial portrait without all the guesswork and a minimum of damage. Call us skeptical that we'll ever see the patent reach a shipping product, though -- even if it was limited to rugged cameras, a mode built almost exclusively around voiding the warranty probably wouldn't sit well with Nikon's accountants.

Node modular iOS sensor hands-on
With the spate of bad publicity surrounding all those Kickstarter projects that never make it beyond the funding stage, there's a certain surreality to actually holding a crowd-funded device in your hands. But here it is, the Node, a project we highlighted in its infancy, way back in February. The whole thing blew way past its funding goal, scoring $76,000 out of a requested $50,000. And now, roughly eight months later, the product has been shipped out to enthusiastic supporters all over the place, inside an unassuming white box. Since its inception, the Node's been an interesting (if not particularly easy to explain) proposition. Now that we've got our hands on one, not all that much has changed -- which is to say, in its early stages, there's a lot of potential, but its still a bit of a hard sell. Hardware-wise, the Node's a solid proposition -- the size and shape of a roll of quarters. The body is made of a white plastic, with Node logos indented on either side. Next to one, you'll find a micro-USB port for charging, and by the other, you get the power button, which also serves to turn on the flashlight module. Inside the body, you've got the battery (which should give you 12 to 14 hours with Bluetooth on), an accelerometer, magnetometer and gyroscope.%Gallery-168812%
Caltech laser accelerometer research may bring fine-tuned position tracking, grocery ads
One way that sensors can track your position without using an array of satellites is by measuring your acceleration as you move around -- but unless you're piloting a jumbo jet, current devices aren't very accurate. Researchers at Caltech hope to change all that with a new, ultra-sensitive accelerometer they developed, which uses laser light to detect motion changes. The scientists managed to shrink a so-called large-scale interferometer down to micro-scale sizes, creating a device "thousands of times faster than the most sensitive sensors used today." That could allow a smartphone with such a micro-sensor to detect your exact position even while inside a grocery store, and flash "ads and coupons for hot dog buns" while you're in the bread aisle, according to Caltech. All that sounds good, but we can perhaps think of more inspiring uses for the new tech.
Delta Six controller gets redesigned, Kickstarted
Most video game controllers sporting a firearm form factor are a far cry from realistic -- bright colors, odd shapes and obvious thumbsticks leave many accessories looking more like toys than weapons. Not David Kotkin's Delta Six. This gun-shaped controller's first prototype looked so much like a real rifle, Kotkin told us, it had to be redesigned. An orange tip, whitewashed body and a few less authentic looking components don't make the Delta Six look any less believable as a digital soldier's modern musket, but it does make it less likely to be mistaken for the real McCoy. The peripheral's internals haven't changed though -- an accelerometer to help players aim and turn, cheek-sensing pressure sensors (for looking down the scope), faux-recoil and its assortment of modular components are still all on target. Like all budding hardware projects these days, the Delta Six is looking towards the crowd to source its production. According to the peripheral's Kickstarter page, the Delta Six will be available between July and August next year, boasting compatibility with the Xbox 360, PS3, PC, Wii U and even the OUYA. Pitching in $89 buys the basic submachine gun body (with a free rifle attachment for first-week buyers), and subsequent levels tack on additional attachments, bonus items and more. Kotkin needs $500,000 to make his rifle-shaped dream a reality. Like-minded FPS gamers can join him at the source link below. Not a dreamer? Feel free to read on for the official press release (plus a video and an additional image), instead.
MooresCloud Light runs Linux, puts LAMP on your lamp (video)
Yes, we'll admit that we borrowed that pun in the title. MooresCloud founder Mark Pesce's Xzibit reference is still a very apt description of the Light, his company's Linux-based LED lamp. The Australian team's box-shaped illumination runs the open OS (including a LAMP web server stack) on an integrated mini PC with an accelerometer and WiFi. The relative power and networking provide obvious advantages for home automation that we've seen elsewhere, but it's the sheer flexibility of a generalized, web-oriented platform that makes the difference: the Light can change colors based on photos or movement, sync light pulses to music and exploit a myriad of other tricks that should result from a future, web-based app store. When and how the Light launches will depend on a Kickstarter campaign to raise $700,000 AUD ($717,621 US) starting on October 16th, although the $99 AUD ($101 US) cost is just low enough that we could see ourselves open-sourcing a little more of the living room. At least, as long as we don't have to recompile our lamp kernel before some evening reading.
Kinect for Windows SDK gets accelerometer and infrared input, reaches China and Windows 8 desktops
Microsoft had hinted that there were big things in store for its update to the Kinect for Windows SDK on October 8th. It wasn't bluffing; developers can now tap a much wider range of input than the usual frantic arm-waving. Gadgets that move the Kinect itself can use the accelerometer to register every tilt and jolt, while low-light fans can access the raw infrared sensor stream. The Redmond crew will even even let coders go beyond the usual boundaries, giving them access to depth information beyond 13 feet, fine-tuning the camera settings and tracking skeletal data from multiple sensors inside of one app. Just where we use the SDK has been expanded as well -- in addition to promised Chinese support, Kinect input is an option for Windows 8 desktop apps. Programmers who find regular hand control just too limiting can hit the source for the download link and check Microsoft's blog for grittier detail.
Delta Six controller brings fragging to life, worries your friends
Chances are you know someone who takes their CoD a little too seriously -- well, this peripheral is for them. The Delta Six controller is the latest brainchild of Avenger inventor David Kotkin, made to please hardcore FPS gamers with immersive and responsive input. A built-in accelerometer is used for aiming, while the faux recoil and acting out a reload will put you closer to real combat than an appearance on Stars Earn Stripes. The hardware also features a scattering of pressure sensors -- allowing you, for example, to bring up the sights by meeting cheek with gun body, or if you're feeling lazy, squeezing the side of it instead. Depending on your class bias, you can add and retract plastic from the main frame for an SMG, assault or sniper rifle form factor (see below for the gist). There's no word on availability, or if it will actually improve your game, but the price is slated as $89 at launch. After the break is a short product demo in video form, although we suggest you skip straight to 1:30 to avoid the awkward live-action CTF scene.
Scosche's Rhythm pulse monitor for iOS tracks your run, lets you change the beat (video)
"Appcessories" is probably one of the more abrasive, yet devilishly descriptive, portmanteaus we've heard in recent years. But, if you're still not sure what it means, consider the Rhythm pulse monitor from Scosche a perfect example. The forearm-mounted device is a pulse / heart rate monitor with an iOS companion app. Working with some of your phone's inner smarts (like GPS), along with a dedicated accelerometer, the hardware / software combo logs vital data from your work out, which you can then share with the world, or enjoy broken down into detailed statistical analysis. If you've ever gone jogging with your iPhone, you'll know how fiddly it can be to change music tracks on the hop, so you'll be pleased to know the Rhythm covers that too. If this sounds like what your workout is missing, you can strap-up right away from any Apple or AT&T store (real or online) for $99, with other outlets, including Best-Buy stocking in time for Christmas.
