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%
Emotiv EEG headset hacked into VR trapeze act, lets you fly like Superman (video)
Last year, Rensselaer Polytechnic Institute students built a virtual reality contraption that let them soar through the sky, held aloft by a trapeze harness and seeing through HMD-covered eyes. This year, they're controlling it with the power of their minds. For his master's thesis, project leader Yehuda Duenyas added an Emotiv headset -- the same one controlling cars and the occasional game -- to make the wearer seemingly able to levitate themselves into the air by carefully concentrating. Sure, by comparison it's a fairly simple trick, but the effect is nothing short of movie magic. See it after the break. [Thanks, Eric]
German researchers take mind-controlled car for a carefully-controlled spin
Emotiv's mind-reading EPOC headset may not have changed the face of video games, but it looks like it's proven to be more than adequate for a team of German researchers, who've used it as the key component in their BrainDriver project. Yes, that's a mind-controlled car and, after a bit of training, is does appear to have performed reasonably well -- albeit with a slight delay that makes any real world test a worse idea than it already was. Interestingly, this latest effort actually follows some previous attempts at a completely autonomous car by the same group of researchers at the Freie Universität Berlin, and they say that the two could eventually be combined at some point in the distant future -- for instance, in a taxi that's able to drive itself but also responds to the thoughts of its passengers. Head on past the break for the video.
Rovio robot controlled via Skype with Emotiv brain-reading headset
The Emotive EPOC "mind-control" headset may not be quite as advanced as some of the brain-reading devices unavailable to the general public, but it looks like it's at least accurate enough for some basic tasks -- like controlling a WowWee Rovio robot via Skype. That impressive feat was accomplished by the folks at ExtremeTech, who paired the headset with the Robodance 5 software program and Skype (not to mention plenty of custom code), which allows the Rovio to be controlled from afar using both facial and mental commands. Needless to say, that's a lot easier said than done, but you can check out the results in the video after the break, and find the complete details on the project at the source link below.
Emotiv EPOC gets reviewed by Joystiq, proves once and for all that videogames turn your brain into mush
We don't want to ruin everything for you, but after some extensive testing by our friends over at Joystiq, it looks like the promising Emotiv EPOC needs a little more time in the thought sensing oven. In its review Joystiq points out the fragile, hard-to-handle nature of the $299 device, but more disappointingly found the thought-sensing functionality of the sensor-stuffed EPOC headgear to be a bit too random, haphazard and inaccurate to actually be enjoyable. Of course, you could blindly assume that 400 hours spent in WoW and a six digit gamerscore has somehow disqualified this Joystiqer's mind from those joys of telepathy, but before you plunk down your hard earned cash and shave off contact points all around your skull, we'd say the full review is at least worth a skim.
Review: Emotiv EPOC, tough thoughts on the new mind-reading controller
We live in exciting times. You can, today, right now, actually buy in real life the kind of sci-fi gear you only expect to find in a video game. Controlling things -- anything but your own body, really -- with just your thoughts is a fantasy and sci-fi staple, whether it be Darth Vader force-choking some mouthy Imperial admiral or Professor Xavier commanding the X-Men from the comfort of his wheelchair, finger pressed to temple in grim concentration. But that fantasy is now reality, and you can control things (well, a thing) with just the power of your mind. Think it and your computer does it, no more pesky mice or keyboards or even voice commands. Or so the people at Emotiv would have us believe. Being the kind of guy who absolutely cannot wait for the day when, as Jonathan Coulton sings, "the things that make me weak and strange get engineered away," I pre-orded Emotiv's thought-controlled EPOC mind-computer interface device as soon as I thought I had $299 to spare. As it turned out, being the first on your block with the new toy comes with a real risk: you might end up buying a frustrating experimental prototype for the cost of five new video games. %Gallery-83470%
The Emotiv Epoc brain controller is supposedly out now ... did you get one?
Project Natal aims to revolutionize video games by doing one simple thing: removing the controller from the video game equation. The Emotiv Epoc aims to revolutionize video games even harder by removing the entire human body from the video game equation ... well, except the brain. The would-be mind-control device made an inauspicious debut at the 2008 Game Developers Conference where it failed to sway a skeptical live audience (including us!) -- the company later pinned the blame directly on interference from the sound crew's fancy wireless headsets. Now, a year-and-a-half later, Emotiv is finally shipping the $299 device this week, which means, if you pre-ordered the device (alas, that first shipment is all sold out) it should be in your hands (and on your head) this week. We're not sure what to make of the lack of press outreach, but we'll be at CES in January and hope to give the Epoc another trial. In the interim, if you want to drop $299 on the thing, "orders placed will be shipped within 2 weeks." If you've got one already and want to share some pictures and feedback, you know where to find us. %Gallery-16463%
Emotiv mind-control device shipping December 21 for $299
Wait, you guys are still playing video games with your hands? What, are they baby games? For babies? We've been using Emotiv's EPOC human-computer interface for months now, allowing our cerebellums to play our games for us, completely cutting our appendageal middle men out of the equation. You'll have the same opportunity on December 21, when Emotiv ships limited quantities of the device to customers who decide to pony up for the $299 price tag. Of course, it doesn't work with all your games. Actually, from what we've seen, it's only capable of making boxes spin around and disappear. What it's really great at, however, is creating super awkward press conferences. [Via Engadget]
Emotiv EPOC human-computer interface supposedly on track to ship next month
Remember that Emotiv EPOC mind-controlled USB controller from last year? Well, we've been dreaming of controlling a game of pong with merely our thought waves ever since, and it looks like our wish might at last be granted. According Emotiv's site, the $299 headgear will be shipping in limited quantities to US customers on December 21st, just in time for your thoughts of the holidays to coalesce into a concentrated, computer-controlling tip. The device works with 14 "saline sensors" applied to the head, in addition to a gyroscope for controlling a camera or cursor, and it comes with the "EmoKey" software to define keyboard shortcuts to be activated by your various expressions and thoughts. Will computer use ever be the same? Yes, probably. [Thanks, Dan]
Emotiv's Epoc mind-controlled device delayed till next year
Not so long ago, in the cold, frosty month of February, we heard about mysterious headgear (an update of Project Epoc) that, if worn, could be used to do stuff like play insanely simple video games (emphasis on insanely). We also heard that this USB unicorn of the gaming universe would be ready by "Christmas" -- whatever that is. Well, according to Big Download, who spoke with a PR rep from Emotiv, the device has been delayed until "sometime" in 2009. The reason for the delay? The company wants to "make sure" the device works "as planned." Glad to hear it -- since we weren't interested in it as a fashion statement alone.
A hands-free interface for Second Life
Standing in front of a large-screen television, leaning, turning, and twisting as the on-screen character mimics his actions, Philippe Bossut could be playing the latest Wii game. But he is not wielding a Wiimote or any other controller, and Bossut's avatar is flying not through Super Mario Galaxy, but Second Life. Through the use of a special 3D webcam and some custom software written by Bossut, Segway-inspired movement in the real world can control things in the virtual world. Running, turning, flying, even creating objects are done with nary a keyboard or a mouse in sight.Back in the 80s, virtual reality was cumbersome and uncomfortable, requiring a head-mounted display and a special glove to move around the world. Twenty years later, the display is gone and the gloves are off. We've had Second Life to be the world of imagination; now we're developing the means to put ourselves into it. HandsFree3D currently can do little more than move your avatar around -- but imagine if this was combined with puppeteering -- the ability for your avatar to mimic your real-life facial expressions and body language? And perhaps add in the Emotiv headset that reads moods and emotions straight from your brain? This truly revolutionizes interactions with the virtual world and those who dwell within it. In a few years, the idea of sitting at a keyboard to play a game may well seem quaint and old-fashioned.Check out the video of HandsFree3D in action after the break.
GDC08: 'Brain control' Emotiv headset, round two
Though their press conference on Tuesday night was ... well, it was a disaster (watch our video to relive every cringe-inducing moment), that didn't stop the electroencephalographers at Emotiv from demoing their technology on the GDC show floor to, evidently, better effect. Mahalo Daily's Veronica Belmont donned the cephalopodic contraption and, using nothing more than the power of her mind, managed to make a box disappear. While the technology appears to work well enough (now), we're still not sold on it as a real gaming interface and not a novelty. *concentrates on finishing post*
GDC08: Watch Emotiv's 'performance anxiety'
Emotiv's press conference was less than stellar (if you recall). Technical problems plagued the presentation, making us walk away saying "wow" ... but for all the wrong reasons. We were skeptical about brain controlled gaming, and Emotiv's conference did little to change our jaded expectations. The test subject utterly failed to produce the results the company expected, much to the dismay of the presenters. Watch the awkward silence that fills the room as we wait (and wait) for the test subject make a block disappear with the power of his mind! Afterwards, the company was forced to continue with a brave, but awkward presentation where we're encouraged to use our imaginations in lieu of a working demonstration. Ultimately, the company blamed the "very high power, frequency-hopping, spread-spectrum technology" headsets used by the sound crew for all the technical glitches. Hmm. Whatever caused the problems Emotiv faced, the night ended up being rather surreal, and we hope this video can capture a little bit of the awkwardness that filled the theater.
GDC08: Emotiv 'brain control' headset shows its kinks
"I think we found a bug," mocked an audience member during an embarrassing lapse in the presentation, one of countless hiccups that marred Emotiv's would-be grand unveiling of the "world's first consumer 'Brain Computer Interface'" (not "Brain Control Interface," as the press invite alluringly stated). Spunky CEO Nam Do kicked things off with a burst of energy, firing off adjectives like "super cool" and "uber-cool" to describe his company's 'next generation human-machine,' a conscious and non-conscious processor with a three-part 'total communication' interface: affectiv, expressiv and cognitiv. Clearly, something was missing. Nam explained that the machine could read feeling and emotion, things that "distinguish us from humans ... er, computers!" An assistant, Marco, entered stage right sporting Emotiv's neuro-headset, a mess of tentacled sensors wrapped around his temple, as Nam introduced Marco's virtual counterpart, Emobot. A robot head with a cute, round face began to mimic Marco's facial expressions on a large screen behind Nam. "Look cute, look cute," goaded Nam, and Marco and the Emobot responded, blinking their eyes and pursing their lips. Emobot followed along for a few more moments before freezing up -- and it was onto the next demonstration. Nam pressed Marco to "think of something, and make it happen" by manipulating a three-dimensional cube now occupying the center screen. A simple 'zoom' command seemingly worked, but when told to mind-push the cube along multiple axes, Marco failed. "Weak mind, weak mind," teased Nam, warding off the inevitable tension. He filled the pause with pseudo-science, something about electrical impulses converted into an image of thought within a roughly 90,000-dimensional space. (90,000 dimensions? Had we heard that right?) Marco was still squeezing his eyes shut, carefully molding thoughts with his hands. Still nothing ... and then ... the cube spun briefly to life. "You feeling okay to do the risky one?" Nam asked. (No, it was not a question.) %Gallery-16463%
Emotiv to make mind-controlled games a reality by Christmas
The idea of wearing a funny hat to mind control software is certainly nothing new 'round these parts. Now Emotiv Systems returns with an update to their Project Epoch USB headset. Crave went hands-on with the system which required a short, six-second calibration before entering the first "game." At that point, Crave was able manipulate a simple cube on the screen with varied success at making it disappear or pull forward. Oooh, what fun! Mind you, it's just a prototype and we've seen this tech applied to old-school arcade games like Pong and Space Invaders to great effect. You'll get your chance soon enough as Emotiv plans to launch the first thought-controlled, consumer gaming device this Christmas for $299 with at least one bundled PC game. One more picture of that Alien face-hugger of a headset after the break.
