After Math: Life imitating art imitating life
Between the political theater and unreal earnings reports, this has been a surreal week for the ages. But while you were glued to the news feeds, an AI-generated art piece sold for silly money, NASA fixed the Hubble by jiggling its handle and a band of clever thieves perpetrated a multimillion-download ad scam that would put the Ocean's crew to shame.
Teach valuable STEM skills with electronic papercraft noisemakers
*Hitches up onion belt* Now back in my day, our papercraft activity books just folded up into something pretty. And we liked it that way. But you kids, with your Nintendoodads and Snapcharts, well that just isn't good enough, is it? No, your paper-based projects have to employ all sorts of electrical circuits, teach STEM skills, make music and ok this is actually pretty cool.
Forget training wheels: This bike balances itself
Training wheels are great for getting kids rolling, but they don't really develop the balance required for real riding. Jyrobike takes a different approach to the learning process, providing a more authentic cycling experience while still offering the stability new starters need. That's because it's self-balancing, and though that sounds too good to be true, the technology that makes it possible is actually quite simple. Contained within the front wheel is a weighted, motor-driven disk that gets up to several thousand revolutions per minute (RPMs). This spinning disk, which emits a dull hum when at full speed, exerts a gyroscopic force that pushes against the turn and lean of the front wheel. As the rider tilts towards the point of no return, the front wheel corrects and as a result, nudges the child into a balanced body position. Watching someone ride a Jyrobike doesn't give you a good idea of how stable the thing really is, but we were incredibly impressed by a live demo. With just a small amount of forward momentum, the prototype easily shrugged off sideways slaps with only a slight waver.
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]
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%
Mosoro releases its Bluetooth LE sensors and SDK for VIP appcessory developers
Since we last heard about Mosoro's Lego-brick sized Bluetooth LE modules, they've changed their names, picked up another member and are now making their way to iOS app developers. The 3D-Motion's got an accelerometer, gyroscope and magnetometer, while the Enviro measures temperature, humidity and barometric pressure. New to the team is Proximity, useful for triggering location-based apps and tracking motion for creating alerts. All three rechargeable Bluetooth low energy sensors have "shake-to-wake" support, an RGB "glow-cap" for notifications and a humble programmable button. They are expected to hit retail in fall 2012, but "VIP" app developers can grab them now, as well as the SDK which simplifies iOS Bluetooth integration. Got the ideas and inclination to become one of Mosoro's "rock star app-developer partners?" Then go sign up on the website and see if you make the VIP grade.
Microsoft earns patent for claimed wireless charging improvement, pad with info screen
Device makers are bent on bringing us inductive charging, and Redmond has joined the fray with a recently allotted patent that describes all kinds of tech that could make it work better. For the charging itself, a trick is proposed that's similar to one we've seen before -- careful matching of the resonant frequency of charger and device. That would amplify efficiency and allow more than one device to be charged at a time. To make it easier to use, a pressure sensor could detect if a device was on the pad, with different parts of the pad allocated for smartphones or tablets, for instance. The patent also proposes a display placed opposite the charger to give it another use when it's not juicing, which would be determined by a gyro to sense which side was facing up. Of course, a lot of patents are whimsical things, which never amount to anything -- but judging by the detail in this one, Microsoft may have something more concrete in mind.
Black and Decker screwdriver senses your hand movement to adjust speed, direction (video)
Were you feeling the need for new tech to replace the switches that control direction and speed on your cordless screwdriver? Us neither, but we're not the braintrust at Black & Decker, which just launched the Gyro 4V Max, the "world's first motion-activated screwdriver." The company put an InvenSense MEMS gyroscope in the new model, so all you have to do to change the direction or speed is rotate your drilling hand one way or the other in varying amounts. After you've polished off that Ikea shelf, it should be ready the next time you haul it out of the toolbox, with a Lithium-ion battery that stays juiced for as long as 18 months. Judging by the video below the break, it actually looks pretty clever, and at $40, why not start dragging your tools out of the stone age?
Google patents Project Glass motion-based theft detection, locks up if it feels 'unnatural' movement
We know that you're never gonna take your Google glasses off, but if some nefarious lout feels differently, the boys and girls in Mountain View's X lab have got you covered. The company has patented a system whereby the device can identify "unnatural" movements and lock the headset if it feels the violent motion of them being wrenched from your face. Even better, while your would-be assailant is making off with the $1,500 gear, it'll be contacting the authorities to ensure that they can't get far with their ill-gotten HMD. If nothing else, we won't worry as much when pre-order customers 782 and 788 go out of an evening.
Google Maps offline for Android is available today in version 6.9, also Compass Mode for Street View
Google showed off offline Google Maps at its event earlier this month, and now during I/O it's ready to turn the feature on. We've got a couple of video trailers for offline Google Maps here (embedded after the break), users with Android 2.2 devices and above should keep an eye on Google Play for the new version of the app. Also new in this version is the Compass Mode for Street View shown off today, that lets you look around places as though you were there based on your device's gyroscope and even go inside. We're not all seeing it on our devices yet, but the updated version has already been spotted on a Galaxy Nexus or two.
Switched On: Extra Sensory Perception
Each week Ross Rubin contributes Switched On, a column about consumer technology. At Intel's CES 2012 press conference, the giant chipmaker justified calling thin notebook PCs "ultrabooks" by noting how the devices would increasingly be characterized by more than their thinness. The integration of sensors has become so core to the modern smartphone experience that their absence would make using such devices untenable.Most of that differentiation was based on plans to integrate the kinds of sensors that have become commonplace in smartphones and tablets, sensors that can detect location, motion, orientation and proximity. The integration of sensors has become so core to the modern smartphone experience that their absence would make using such devices untenable. Imagine if we had to manually reorient a display every time we wanted to play a game or take a photo or if we had to avoid activating a button with our cheeks when holding a phone against them.But as Switched On discussed in taking on how screen size affects form factors, what is a limitation of form factor today may not hold true tomorrow. Already, of course, smartphones can tap into remote intelligence for applications such as remote camera viewing or unlocking of doors via services from home security companies such as ADT and Vivint. From around the world, you can even remotely start a vehicle using the Viper SmartStart app. But there are increasing opportunities for smartphones to act on information from sensors that are not embedded into their shells.
Gyroscope manufacturers benefit as iPhone, iPad sales soar
Apple isn't the only company reaping the benefits of increased sales of the iPhone and iPad. IHS iSuppli is reporting that sales of MEMS (microelectromechanical systems) gyroscopes have skyrocketed as well thanks to use of the devices in Apple's mobile line. (Photo above is of an iPhone 4 MEMS gyro -- not this kind of gyro -- component.) MEMS gyroscopes accounted for US$665.4 million in revenues in 2011, compared with only $394.5 million in 2010 -- a 66% rise in revenues in just one year. IHS iSuppli explains the popularity of MEMS gyroscopes in today's mobile electronic devices: "The rise of gyroscopes to the top was in large part due to the boom in 3-axis versions of the device, used mostly in tandem with 3-axis accelerometers for more accurate motion sensing. While accelerometers are responsible for correctly orienting phones and tablets to the viewer's perspective whether the devices are held vertically or horizontally, gyroscopes improve the motion-based interface, especially for gaming. Emerging applications for gyroscopes in smartphones also include optical image stabilization and navigation-related functions." In Apple's iPad and iPhone, the MEMS gyroscopes come from one supplier: STMicroelectronics. Half of the company's 2011 MEMS revenues came from sales to Apple. In the near future, it's expected that companies like Apple will switch to what are called 6-axis inertial measurement units, which combine the 3-axis gyros and 3-axis accelerometers onto one chip.

Windows 8 adds sensor support, will be the PC to turn, turn, turn
Microsoft is slowly turning its stalwart desktop OS into a mobile powerhouse. The company just keeps rolling out improvements and features for Windows 8 aimed at really making upcoming tablets competitive with their Android and iOS-based market mates. After cramming mobile broadband tools into the tile-happy OS, now Redmond is turning its attention towards sensors. The next version of Windows will offer integrated support for gyroscopes, accelerometers, magnetometers and ambient light sensors among other things. Devs will even be able to use multiple sensors in conjunction for more accurate interaction. Check out the video after the break for more details.
360 Panorama app now available for Android users, no gyroscope necessary (video)
Looking to capture panoramic photos on an Android handset? Well, you've certainly got plenty of options -- including, as of today, Occipital's 360 Panorama, which just hit the Android Market. Compatible with devices running Android 2.3 or above (with the exception of Honeycomb), the app offers much of the same functionality you'll find on the previously released iOS version. Just tap a button, pan your handset across any given area and watch your photo come to fruition before your very eyes. The tool also allows exposure to fluctuate as a user pans his or her device, thereby creating the potential for HDR panoramic shots during transitions from dark to bright areas. Interestingly enough, this version relies not upon an actual gyroscope, but a "simulated" one, created from motion-tracking algorithms (that's how it works on older 3GS handsets, as well). Users who already have a 360 Panorama account can still use it on their Android handsets, allowing them to upload and store all their photos in one place. Eventually, this storage system will allow for syncing across both iOS and Android hemispheres, though at the moment, it's a strictly web-based affair. Pan past the break for a brief demo video, or check out some sample shots in the gallery, below. %Gallery-140050%
Mosoro Bluetooth LE iOS accessories improve your golf, if the weather's right
So far the appcessories -- yeah we said it, APPcessories -- we've seen include some good ideas, and some less so. The Bluetooth LE 3D-Sport and Weather offerings from Mosoro fall into the former category (if they make their way into a shipping product that is). The 3D-Sport is a motion capture device you attach to sports equipment. The on-board accelerometer, gyroscope and magnetometer beam motion data to your iOS device, where it can be analyzed by Rocky-style Russian coaches to see where your throw or golf swing is going wrong. The latter is a mini weather station that reads temperature, humidity, elevation, and barometric pressure to tell you the conditions where you are right now. More usefully, it nabs your GPS location and uploads it all to Mosoro's aptly named "Cloud" Server that presumably maps out some crazy real-time crowdsourced weather report. Both also use Bluetooth 4.0's low energy technology so they won't need to see a charger for a long time. Now we just need a company that likes collating personal data, perhaps with a weather service, to snap this one up... any takers?
Amazon adds Kindle Fire-specific details to Developer Portal, A's your FAQ
The Kindle Fire may not be hitting the market until November, but Amazon has already updated its Developer Portal FAQ page with an entire section devoted to its forthcoming Android tablet. On the new page, you'll find largely standard information on things like the application process and how to set up an Android SDK emulator, though there are a few more salient tidbits, as well. For instance, Amazon says it will review every app in its Appstore for Fire compatibility, as part of an automated process. Rejected apps, Amazon informs us, will include those that rely on a gyroscope, camera, WAN module, Bluetooth, microphone, GPS, or micro SD. Apps are also forbidden from using Google's Mobile Services (and in-app billing), which, if included, will have to be "gracefully" removed. In terms of actual content, Amazon has outlawed all apps that change the tablet's UI in any way (including theme- or wallpaper-based tools), as well as any that demand root access (it remains to be seen how the company will treat the root-dependent apps already in its store). Interested devs can find more information at the source link, below.
Mopho DJ uses your iPhone to track turntable movement (instead of your movements)
We have to admit, we never thought of this one -- and it's pretty, pretty slick. Instead of using time-coded vinyl to interface your turntable with your computer as with Final Scratch Pro or Serato Scratch, Nicholas J. Bryan's Mopho DJ uses an iPhone. That's right, our man at Stanford University literally affixes his smartphones to his decks via a perspex disc and some sort of adhesive. The smartphones each run an app which sends accelerometer and gyroscope data to a computer, which then adjusts playback of your music accordingly. It's still a work-in-progress at the moment, but if you're in Oslo the first week in June make sure you check it out at the NIME (New Interfaces for Musical Expression) conference. This is definitely the kind of iOS location tracking we can get behind! Check it out on video after the break.
NASA concludes Gravity Probe B space-time experiment, proves Einstein really was a genius
Well, it looks like Einstein knew what he was talking about, after all. Earlier this week, researchers at NASA and Stanford released the findings from their six-year Gravity Probe B (GP-B) mission, launched to test Einstein's general theory of relativity. To do so, engineers strapped the GP-B satellite with four ultra-precise gyroscopes to measure two pillars of the theory: the geodetic effect (the bending of space and time around a gravitational body) and frame dragging (the extent to which rotating bodies drag space and time with them as they spin on their axes). As they circled the Earth in polar orbit, the GP-B's gyroscopes were pointed squarely at the IM Pegasi guide star, while engineers observed their behavior. In the universe outlined by Einstein's theories, space and time are interwoven to create a four-dimensional web, atop which the Earth and other planetary bodies sit. The Earth's mass, he argued, creates a vortex in this web, implying that all objects orbiting the planet would follow the general curvature of this dimple. If the Earth's gravity had no effect on space and time, then, the position of NASA's gyroscopes would have remained unchanged throughout the orbit. Ultimately, though, researchers noticed small, but quantifiable changes in their spin as they made their way around the globe -- changes that corroborated Einstein's theory. Francis Everitt, a Stanford physicist and principal investigator for the mission, poetically explained the significance of the findings, in a statement: "Imagine the Earth as if it were immersed in honey. As the planet rotated its axis and orbited the Sun, the honey around it would warp and swirl, and it's the same with space and time. GP-B confirmed two of the most profound predictions of Einstein's universe, having far-reaching implications across astrophysics research. Likewise, the decades of technological innovation behind the mission will have a lasting legacy on Earth and in space." The GP-B mission was originally conceived more than 50 years ago, when the technology required to realize the experiment still didn't exist. In fact, the experiment didn't actually get off the ground until 2004, when the satellite was launched into orbit 400 miles above Earth. After spending just one year collecting data (and an impressive five years analyzing the information), NASA has finally confirmed something we always quietly suspected: Einstein was smart. Head past the break to see a more in-depth diagram of how the GP-B gathered its data.
Apple is world's second-largest buyer of accelerometers, gyroscopes, microphones
The popularity of Apple's iOS devices propelled the manufacturer to the top of the consumer microelectromechanical system (MEMS) sensors market. The millions of iOS devices in the wild are chock full of 3-axis gyroscopes, accelerometers, microphones and bulk acoustic wave (BAW) duplexers. In 2010, Apple's purchase of these sensor components rose 116.7 percent year over year and climbed to a whopping US$195 million. This figure is only $5 million behind market leader Samsung, which purchased $200 million in MEMS sensors for its mobile phones and tablet devices in 2010. These numbers pushed Apple and Samsung above former leader Nintendo, which ruled the industry when the Wii and the Nintendo DS were at their pinnacle. Apple's influence in the MEMS industry is extensive, according to Jérémie Bouchaud, principal analyst for MEMS at iSuppli. Bouchaud suggests Apple created a new market for these sensors with the original iPhone, which was one of the first handsets to include an accelerometer. Apple also revived the tablet industry, which relies heavily on MEMS sensors, with the debut of the iPad in 2010.
