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.

Charge your USB gadgets by breathing
USB devices do everything these days, including charge your gadgets with only the power provided by your breathing: specifically, the act of moving one's chest in and out. Just in case you thought this required sticking a gadget down your throat, see the image above and note that it's attached to the outside of the model's chest. The instructions for building your own breathing powered USB charger are over at instructables, and the kit only requires simple equipment like a spare CD drive, some elastic bands, and an electric circuit. You've got all that lying around, ain't ya? Well then, stick it all together and get breathing. Unfortunately, it only produces around 5 volts, so you'll have to breath a lot whole lot to get any meaningful charging time from this invention. And don't even think about attaching it to the cat.[Via Gadgets-Weblog]
CPR Teddy cuddles up nicely, teaches resuscitation
We've seen soft 'n cuddly teddies transformed into nearly every gadget imaginable, but the Save-A-Life Training Center is hoping to teach common individuals how to perform CPR with the use of a less frightening subject. The oh-so-adorable CPR Teddy looks a whole lot better than other CPR training bots that we've come across, and after squeezing one of his paws, "voice prompts walk you through the correct procedures for choking rescue and infant / child CPR." It gets a bit dodgy, however, when you have to submerse yourself in the moment and actually press down on his red heart patch as the bear's built-in metronome paces you. Subsequently, the creature's bow tie actually lights up in green or red to alert you of how you're doing, and his chest will actually rise up as you perform rescue breathing and simultaneously inhale mounds of fur. The basic CPR Teddy kit rings up at just $79.95, but we'd highly recommend picking up a few extra masks to avoid getting choked up yourself when performing mouth-to-mouth.[Via Uber-Review]
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]
Toy car controlled by breathing
While controlling a full-sized automobile with a PSP may be impressive, at least this project has some amount of practicality. Musicians and singers, listen up, because this breathing-controlled car could provide the perfect mix of practice and pleasure to get your controlled breathing, well, under control. Even if you couldn't carry a tune in a bucket, Matthew Brown's creation gives you a chance to have some fun while blowing off some steam. The aptly named "Breath Control Car" was designed to make the mastery of controlled breathing a bit more enjoyable, and he pulls it off by using a MIDI breath controller to channel puffs to a MAX/MSP. MIDI signals are converted to serial data, where those signals are beamed via Bluetooth to a PIC chip, and finally to a servo that directs the car. If all that sounds like hot air, here's the deal: the harder you exhale, the harder it steers right, while softer breaths steer it left. The forward and reverse functions are handled by a simple remote-control, presumably to avoid hyperventilation. If you've been tooting your horn about getting serious with your breathing, but need a more riveting reason to practice, watch this machine in action to see what Matthew's breath car can do for you.
