Muscle sensors may let you control a drone by clenching your fist
MIT has developed a system that uses muscle sensors to control robots more intuitively.
MIT's 'RoboRaise' helps you lift things by studying your muscles
It's all well and good having a virtual assistant like Alexa or Siri in your lounge, but they make for a pretty useless robotic companion when it comes to shifting a sofa or getting a heavy box from a cupboard. MIT CSAIL has a solution in its sights though, and has developed a robot that can help lift things by studying a human's biceps.
CTRL-Labs' EMG wristbands may spell the end for keyboards and mice
From the earliest days of punch cards, interacting with computers has always been a pain. Whether it's a keyboard and mouse, joystick or controller, getting the thoughts out of our heads and into the machine requires numerous, unintuitive processes. But until we start implanting USB ports into our brains and downloading our thoughts directly, we'll have to make do with the neural signal-detecting wristbands being developed by CTRL-Labs.
Columbia University's low-cost robotic arm is controlled by facial muscles, we go face-on (video)
We've seen Emotiv's Epoc headset control cars and trapeze acts, but now a small posse of students at Columbia University is teaching it how to control a robotic arm. The appendage, aptly named ARM for Assistive Robotic Manipulator, was envisioned as a wheelchair attachment to help the disabled. According to the team, the goal was to keep costs in the neighborhood of $5,000 since insurance outfits Medicare and Medicaid won't foot a bill for assistive tech that's much more than $10,000. To keep costs low, the crew built the limb from laser cut wood, and managed to keep the final price tag at $3,200. Since picking up EEG signals and interpreting them accurately can be tricky, the group says it settled on monitoring EMG waves, which are triggered by muscle movements, for additional reliability. Lifting your eyebrows makes the device open its grip, clenching your teeth shuts it and moving your lips to the left and right twists the claw, while other motions are currently handled by using a PlayStation 2 controller. In the lab, the contraption has seven degrees of freedom, but it was reduced to five when we took it for a spin. It was hit or miss when this editor put the headgear on, between making sure facial gestures were spot on and the equipment's attempts to pick up clear signals.%Gallery-187534%
DIY cyborg appendage is less exciting than it sounds (video)
When we envision our transhumanist future, it's a little more profound than simply adding a sixth finger... but we suppose you've gotta start somewhere. Instructables user and employee Frenzy gave himself a rather primitive extra digit as part of a project for an Electronics and Robotics class at San Francisco State University. Sadly he doesn't provide step-by-step instructions for building your own cyborg appendage, but it doesn't seem too difficult. Frenzy borrowed heavily from other projects, using EMG sensors to trigger a servo controlled by an Arduino, which he strapped to the back of a glove. Like we said, doesn't seem particularly hard, once you figure out how to get the microcontroller to play nice with the sensors. Obviously this is just one small step step for DIY cyborgs. Next, we need to graph on a few extra arms to make one-man liveblogging a much simpler endeavor. To see Primitive Transhumanism #2: Sixth Finger in action, head on past the break.
Microsoft patent brings us one step closer to real-life Deus Ex
In the Deus Ex universe, technology has advanced to the point where human beings are able to augment themselves with technology, enhancing their abilities and giving themselves raspy, chain-smoking truck driver voices. It's what came to mind after our pals at Engadget discovered a Microsoft patent for an EMG (electromyography) device.The patent calls it the "Wearable Electromyography-Based Controller," which would potentially allow users to control their devices (smartphone, computer and the like) through movement – the device would monitor muscle movement, either through a wireless or wired connection. The patent suggests a variety of different devices on Microsoft's mind: the armband seen above; a shirt (smartshirt, we like to call it); and even a pair of sunglasses, though they appear less badass and expensive than Adam Jensen's or, heck, even the shades JC Denton rocks in the original Deus Ex.We just hope one of those EMG devices has a built-in niceness chip, to prevent future cyber-people from freaking out over tiny problems.
Microsoft granted patent for wearable EMG device
Those muscle spasms? They're now good for something. Okay, so Microsoft's just-granted patent for a wearable EMG device doesn't really thrive off of involuntary twitching and such, but it does use your movements to control your smartphone, notebook and other gadgets. The "Wearable Electromyography-Based Controller," which we first glimpsed back in 2010, uses sensors to interpret the electrical signals generated by a user's muscles, and then communicates with the wearer's computer via a wireless (or wired) connection. Redmond envisions the wearable device in various incarnations: as an armband equipped with sensors, a shirt, eyeglasses and even nodes attached directly to the user's body. In the armband example, motion control could be used to interact with a PMP while the user is jogging. No matter the setup, a calibration process allows the system to locate specific sensors and collect information based on specific gestures or movements, which means playing Guitar Hero with only an air guitar may someday be a reality after all.
USB Biofeedback Game Controller lets you play Mario with your guns (video)
Those gun-show tickets you've been offering out to everyone (that nobody ever takes) can suddenly do a lot more, thanks to Advancer Technologies. It's developed an Arduino-based plug-and-play bio-feedback game controller that uses EMG (electromyography) sensors to monitor the electrical activity in your skeletal muscles and turn them into game controls. For example, a bicep twinge represents jump, a gripped fist means run forwards -- as long as you've sufficient definition for those two to be distinctive. Check out the must-see muscle action after the break, or see how it's done at the source link. [Image courtesy of Dreamworks]
Electronic neural bridge helps paralyzed mice walk again, human application might prove tricky
It's only been a week since we heard about age reversal in mice, yet already we've got another big advancement in rodent medical care: a solution for ameliorating the devastating effects of spinal cord injuries. A UCLA research team has shown off a new system that can restore walking motion to a mouse's hind legs, but not only that, it also grants control to the little fella by responding to its front legs' actions. Electromyography sensors detect when a mouse starts to walk up front, triggering electronic signals to be sent to the functional lower portion of its spine, which in turn starts up the rear muscles for a steady walking gait. It's only been tested on a treadmill so far, but the result seems to be a seamless restoration of walking capacity in rodents that doesn't require any outside assistance. The same will be pretty hard to replicate in humans, bipeds that they are, but that's why it's called research and not reobvious.
Microsoft Research patents controller-free computer input via EMG muscle sensors
We've seen plenty of far-fetched EMG-based input methods, like the concentration-demanding, head-based NeuroSky controller, but Microsoft Research is asking for a patent that involves much simpler gestures -- and might actually make a bit of sense. As demonstrated in the video after the break, Microsoft's connecting EMG sensors to arm muscles and then detecting finger gestures based on the muscle movement picked up by those sensors. It does away for the need of a pesky camera (or Power Glove) to read complicated hand gestures, and can even sense modified versions of the gestures to be performed while your hands are full. Microsoft's developing a wireless EMG sensor module that could be placed all over the body, and while like all Microsoft Research projects this seems pretty far from market, there's a small, optimistic part of us that could see some of the benefits here for controlling mobile devices. And boy do we love controlling mobile devices.
SK Gaming wins MLG Columbus
The dominance of Rogue/Mage/Priest continues as SK Gaming defeated eMazing Gaming's faceroll Unholy/BM/Holy comp in the Major League Gaming Columbus Grand Finals 6-3 (best of 11 counting previous matchups). SK Gaming took home the $9,000 Grand Prize in the first leg of the MLG 2009 pro circuit, proving that the US still has a competitive RMP team. Europe's RMP contingent, Ensidia, barely missed the Finals after dropping to eMG in the prior round.Some of the teams didn't do so well despite expectations, such as two-time MLG winners Fnatic, who were playing without their Warrior, Rhaegyn. Fnatic did rather poorly, playing a Rogue/Warlock/Shaman comp that simply couldn't match up against the dominant RMPs or even eMG's Death Knight/Hunter/Paladin. Evil Geniuses also played below par, but there really have to be teams that occupy the bottom of the standings. The good news is that teams collect points through all MLG legs to tally at the end of the season, so we might see some changes in the next MLG stops.All the matches were streamed through three different sites via Octoshape, but the streams were choppy and often stalled more than it did in the first two days of the tournament. It came to the point where the matches were simply unwatchable, which is a shame because there were some pretty good games on the last day. The shoutcasters did an excellent job commentating on the matches but camerawork and the pace of the games were just too fast at times to appreciate. Arena Tournaments could benefit greatly from instant replays, slow motion, and camera angles beyond the third person view. Replays should be available on GotFrag soon.
DIY pervasive health monitor keeps tabs on your vitals
If you think your heart rate-monitoring wristwatch is hot stuff, a homegrown creation from the Berkeley Institute of Design is apt to put that to shame. Dubbed the pervasive health monitoring system, this project involves a TI microcontroller, a Bluetooth interface, audio amplifier, and a trio of low power "instrumentation amplifiers," which creates an apparatus that can communicate wirelessly with your Windows Mobile-based handset (and PC, too). The device is rigged up to record ECG (heart rhythms), EMG (muscle tension), GSR (skin resistance), body temperature and movement information, and while we could certainly attempt to transcribe the creator, why not take a look at the informative video posted after the jump for all the data you could ever desire about this (admittedly fresh) invention.[Via Hack-A-Day]
Brain-reading biofeedback caps on the rise, NeuroSky returns
Pushing the envelope is what it's all about, and for companies cranking out Wiimote-like devices to make gaming and PC experiences more eventful, even that's not enough to satisfy a bevy of outfits with their eyes set on getting biofeedback into games. Companies such as Emotiv Systems, CyberLearning, and our old friend NeuroSky are all looking to take advantage of the public's current curiosity about thought-controlled (and influenced) gaming by offering up electrode-laced headsets that read a variety of brain impulses to effect gameplay. Essentially, these gel-free caps rely on technology such as electromyography (EMG), which records twitches and other muscular movements, and electrooculography (EOG), which measures changes in the retina, in order to change the way games are experienced. For instance, a nervous, uneasy GTA player would barely be able to aim at his / her enemies, while a daydreamer would have a hard time staying on course and reaching full speed while playing Gran Turismo. Unsurprisingly, said companies have noted that "finding their target markets" have been the most difficult aspect, and certain analysts rightfully question whether gamers would actually enjoy such "mentally taxing restrictions" on their games, but if all goes as planned, we should start seeing a few more options in the commercial brain-interface market before too long.
Play Snake on your Nokia Series 60 / 80 by flexing your biceps
A Finnish fellow named Arto Holopainen on the Nokia forums has just come up with a way to control your cellphone without touching the phone -- that is, controlling it via Bluetooth-enabled EMG monitoring devices hooked up to your biceps. Holopainen took a Series 60 (or 80) phone, a small battery-operated Bluetooth-enabled two-channel electromyogram device (you know, the one that takes measurements of electrical muscle activity) and the MuscleMonitor application to run on his phone, and then managed to map various muscle activity levels to cellphone functions. Specifically, he's made it possible to play the classic game Snake through muscle flexing to control the various movements in the game. Holopainen elaborates that one could further map the software so that you could even text message by just flexing your muscles -- why one would want to do this, we have no idea, but we're sure that he looks absolutely ridiculous trying to get a workout by playing Snake.
