Spire breathing monitor can tell if you're stressed, relaxed or focused
Samsung's Galaxy S5 is supposed to be able to measure stress, but there's something about its "heart-rate variability" test that just isn't very convincing. (Namely, if you enjoy a brisk walk and raise your heart-rate slightly, the phone will sometimes report an increase in "stress.") By contrast, a new hip-worn sensor called "Spire" ignores your pulse in favor of monitoring breathing patterns instead. Its creators claim that these patterns can reveal periods of "tension, relaxation and focus," as well as allowing standard fitness tracking.
This skin-sensitive controller ramps up game difficulty when you're bored
The concept of using your emotional state to alter gameplay is nothing new, but the technology to make that happen has frequently relied on cameras and other special add-ons. Stanford University's Corey McCall has a far more elegant solution -- he recently developed technology that builds skin-based emotion detection into an otherwise ordinary gamepad. The controller changes the intensity of a game based on the feelings you convey through breathing, heart rate and motion. It can boost the difficulty level if you're obviously bored, or tone things down if you're taking a challenge way too seriously. There may not be a great need for McCall's approach when systems like the Xbox One can check your pulse at a glance, but it could let console and peripheral makers offer emotion-aware gaming without requiring cumbersome (or costly) extras.
Piezoelectric system turns your balmy breath into pungent power
Researchers at the University of Wisconsin-Madison have come up with a way to produce electricity from just about the most renewable source known to man -- his own breath. It's all thanks to a plastic microbelt developed by engineers Xudong Wang, Chengliang Sun and Jian Shi. Made of a material known as polyvinylidene fluoride (PVDF), this belt produces an electric charge whenever low-speed airflow passes over it and causes it to vibrate -- a result of that vaunted piezoelectric effect. Eventually, Wang and his team were able to tinker with their system to the point where it could produce enough current to charge small electronic devices. "The airflow of normal human respiration is typically below about two meters per second," Wang explained. "We calculated that if we could make this material thin enough, small vibrations could produce a microwatt of electrical energy that could be useful for sensors or other devices implanted in the face." The researchers say their technology could be used to power smaller biomedical devices like blood monitors and pacemaker batteries, which typically don't demand vast amounts of energy. No word yet on when this system could make its way to the mainstream, but we'll be waiting with bated breath.
Siemens creating portable sensor to warn about asthma attacks, breathe deeply until it ships
We all wheeze a little from time to time, at least we do when we've fallen off the fitness wagon and are trying desperately to climb back on. For some it's a little more serious than that, and for those prone to dangerous bouts of asthma Siemens AG has a bit of hope. It's developed a portable sensor that can detect minute increases of nitric oxide in a patient's breath, particles that serve as a sign of an impending asthma attack. The user can then use that information to ingest the correct amount of anti-inflammatory meds. The device is said to be about the size of a cellphone, though unfortunately Siemens didn't specify a model. Like, are we talking a Veer here or a king-sized Nexus S? Inquiring minds want to know.
Yoko Ono regarding Beatles on iTunes: 'Don't hold your breath'
There are two great mysteries of the digital age: how did a Welshman become the most powerful man in Japan and when will the Beatles be available for download on iTunes? While the former will forever remain a mystery, speculation picked up on the latter in 2006 after Apple and Apple Corps -- the record label owned by Paul McCartney, Ringo Starr, Yoko Ono and the estate of George Harrison -- settled a long running dispute. In September of last year, Yoko Ono apparently went so far as to whisper its imminent arrival only to be rebuffed by EMI which licenses the Beatles' recordings. Unfortunately, things don't look any closer to being settled today. Reuters is reporting an impasse, quoting Ono as saying, "Steve Jobs has his own idea and he's a brilliant guy. There's just an element that we're not very happy about, as people. We are holding out." She then added, "Don't hold your breath ... for anything," presumably while cracking a whip and laughing maniacally. Fitting don't you think, as legend has it that Lennon's first encounter with Ono involved her passing him a card that read "Breathe."
Zyxio's 'sensawaft' tech lets you control a cursor with your breath, you lazy jerk
We never knew just how much work it was moving our mouse around our desktop until we blew ourself silly on Zyxio's breath-enabled sensawaft tech. The sensor detects the directionality of breathing, which sounds really easy in theory but took a bit of learning in practice. After a couple minutes of trying, however, we were "blowing with our mind" as the promotional materials suggest, and while we wouldn't call ourselves halfway accurate, we could see ourselves suggesting a mild amount of cursor direction with very little effort after a day or so of use. There's an obvious application for the disabled, but Zyxio also thinks it can talk gamers into using it as a "third hand," and envisions other applications such as controlling a mobile phone or zooming in and out of a GPS view in a car. We can't see it taking the industry by storm, but sensawaft is certainly an impressive and entertaining technology, and with devices in the projected $70 range in Q2 or Q3 of this year, it might not be too expensive for a novelty buy. Check out a video of it in action after the break.
Video: Breath-over-IP concept is a fun way to creep out your friends
This might have been a Crapgadget contender but for the fact it's a homemade system and therefore deserves some kudos for the ingenuity shown. An irrepressible geek by the name of Thomas Edwards has concocted a system for communicating breathing over the interwebs -- a surefire way to take your cyberstalking game to the next level. Employing an Arduino protoshield, AdaFruit Xport shield, Lantronix Xport Direct, and a Kestrel impeller to create the device, Thomas demonstrates a taste for obscure technology usually not seen outside of prototyping labs. Click through for video of a candle being blown out remotely, perhaps the one and only family-friendly use for an instrument like this.[Via Make]
Increased lung capacity in Wrath Beta
While there's no definite word from a blue on whether it's working as intended or not, there's an interesting buff on the Beta servers at the moment: Everyone seems to have a much longer breath timer when swimming underwater. Whereas it took about 1 minute for breath to run out, now it seems to last for approximately 3 minutes. In effect then, it's like everyone has gained the Underwater Breathing racial of the Forsaken. If it's a permanent buff and not just some crossed wires, it should make underwater questing (and there is some in Wrath) a bit easier! Of course, I'm not giving up my Hydrocane just yet, either. It seems like a strange change to make out of the blue, and it does negate one of the Forsaken's racials, more or less.
Georgia Tech researchers demonstrate blowable user interface
Although a team from Kent State already whipped up a method for turning one's PC on / off with a simple puff of air, two gurus at Georgia Tech have created a full-blown (ahem) breath-controlled user interface. The low-cost, localized blowable UI -- cleverly dubbed BLUI -- apparently utilizes a built-in microphone along with a C++ application that computes the blowing inputs. Once installed, users can puff on either side of the screen in order to scroll left / right, icons can be selected depending on the fierceness of the puff and games could integrate the technology in to add another level of interactivity. Notably, the duo behind the creation is already investigating how to avoid false positives (i.e. inputs from nature when outside on a blustery day), and while we're not sure how close this stuff is to becoming commercially available (if at all), you can take a look at a videoed demonstration just beyond the break.

Breath powered USB generator does charging on the go
Hey, we're tired of waiting for wireless charging solutions to actually hit the market just as much as the next guy (or gal), but one inventive soul took that frustration out on a swank DIY project that elicits energy from simply breathing. We've seen the use of hot air in powering gadgets before, but this homegrown USB charger was assembled by simply using "parts scavenged from an old CD-ROM drive, a basic electronic circuit, and a few rubber bands." The chest-worn device was intended to output around one-watt for charging a cellphone, which could purportedly juice it up in just under three hours, but unfortunately for us all, this seemingly brilliant device only mustered about 50mW of energy. Of course, that's still getting somewhere, but we're not exactly keen on wearing this thing around for an entire day in order to add a few battery bars to our mobile. Nevertheless, the creator doesn't look to be giving up on it so soon, and hopefully v2 will allow our breath to add new life to our lappies or electric cars, eh?[Via Slashgear]
