DARPA is helping six groups create neural interfaces for our brains
Elon Musk isn't the only one looking to rummage around inside your skull. DARPA announced on Monday that it has selected its five grant recipients for the Neural Engineering System Design (NESD) program, which it began at the start of this year. Brown University, Columbia University, The Seeing and Hearing Foundation, the John B. Pierce Laboratory, Paradromics Inc and the University of California, Berkeley will all receive multi-million dollar grants to help develop various aspects of the emerging technology.
Implants enable richer communication for people with paralysis
John Scalzi's science fiction novel Lock In predicts a near future where people with complete body paralysis can live meaningful, authentic lives thanks to (fictional) advances in brain-computer interfaces. A new study by researchers at Stanford University might be the first step towards such a reality.
UF researchers let people race drones using their minds
As drone racing gets faster, cheaper and more mainstream, it was only a matter of time before drone pilots ditched the controller and made the leap to an actual brain-computer interface, as these researchers from the University of Florida did last week.
G-Tec Intendix brain-computer interface ready for consumers (video)
If you've seen G-Tec's thought control cap being used to control a Second Life avatar, play a game of Pong, or make music in an orchestral setting, you probably wondered when the thing would become available for less frivolous pursuits (to help the disabled communicate, for starters). Well, it looks like that day is close at hand: With the brand name Intendix, the €9000 (about $12,250) brain-computer interface gives you everything you need to send text messages with brain activity alone via EEG cap. According to the company, most people achieve five to ten characters per minute the first time they use the thing, with some folks eventually typing as fast as 1 character per second. In addition to text messages, the system can also be used to trigger an alarm, send email, or send commands to external devices. There's no word on a shipping date yet, but we did thoughtfully provide that Second Life demo for you after the break.
Thought controlled orchestra makes its debut in Prague
The Multimodal Brain Orchestra had its world premiere last week in Prague, a city known for its big thinkers (and its Velvet Revolution). As a guy in black tie-and-tails led the traditional players through their arpeggios and glissandos, an "emotional conductor" led four performers fitted with G-Tec caps as they controlled both visuals and the sounds, frequencies, and volumes of various instruments. The controls were based on two of the effects that EEGs measure, SSVEP (or steady-state evoked potential) and the P300 signal. While we're not sure if this will ever take off in the classical world, we do think that there are quite a few turntablists who could do some wild things with a thought controlled Kaoss Pad. Are you listening, Korg? Video after the break.[Via Make]
Mind reading gets closer to real thanks to Canadian scientists
Hate to break it to you, but that clairvoyant you've been paying daily to read you fortune cookies while blindfolded actually isn't some sort of medium. Tough to swallow, we know. That said, researchers at Canada's largest children's rehabilitation hospital are getting closer to equipping entrepreneurial individuals with the tools they need to read minds. By measuring the intensity of near-infrared light absorbed in brain tissue, scientists were able to decode a person's preference for one of two drinks with 80 percent accuracy, all without a single minute of training on the human's behalf. This research gives promise to finding out true feelings of those who can't speak or move due to physical limitations, though there's no word on how close it is to becoming viable outside of a lab. As an aside, we hear Professor X is pretty perturbed.
USF scientists develop brainwave controlled wheel chair
Those crazy kids at the University of South Florida are at it again -- they've given us 'intelligent' scarecrows and engaged an RFID network in the fight against Alzheimer's, and now they're doing some rather interesting work with the Brain-Computer Interface (BCI). The device uses an electrode-covered head cap to capture P-300 brainwave responses and convert them into action, such as "typing" or manipulating a robotic finger. The team has developed a motorized "smart wheelchair" that allows users to pilot the chair and even control a robotic arm without any physical movement whatsoever. USF researchers say that this will be a great help not only for those with special needs, but also for the extremely lazy.[Via MedGadget]
Researchers devise neural implant that learns over time
Brain-machine interfaces have done quite a bit in helping handicapped individuals interact with prosthetic limbs, computers and other humans, but a new neural implant concocted at the University of Florida could make all those past devices look archaic. Put simply, researchers have discovered a method that would enable brain-machine interfaces to "adapt to a person's behavior over time and use the knowledge to help complete a task more efficiently." Until now, the brain was the instrument doing all the talking while the computer simply accepted commands; with this method, "the computer could have a say in that conversation, too." In all seriousness, this type of learning mechanism could be game-changing in the world of physical therapy, but we hesitate to give something mechanical inside of our body too much free will, ya dig?[Via Physorg]
Researchers develop robotic brain-computer interface
Brain-computer interfaces have been kicking around for a few years now, but they're relatively slow and unwieldy, which kind of puts a damper on world-domination plans -- the guy with the keyboard would probably be well into the missile-launch sequence by the time you've strapped on your dork-helmet. That might be slowly changing, though, as Caltech researchers are working on a robotic brain-computer interface, which can currently be implanted directly into non-human primate brains and move itself around to optimize readings. Although the MEMS-based motor system that actually moves the electrodes is still being developed, the software to do the job is ready to go, and the whole system being presented this week at the IEEE International Conference on Robotics and Automation in Pasadena. Robot-android chimps? Sure, that's just what we need.
Researchers cram bio-signal monitoring system inside baseball cap
Never before has headgear been so intrinsically linked with actual brain waves. Thanks to a team of researchers looking to create a method for "continuously monitoring high-temporal resolution brain dynamics without requiring conductive gels applied to the scalp," a new baseball cap has been created to do the trick. Said hat conceals five embedded dry electrodes which contact the wearer's forehead, while a single electrode behind the left ear acquires EEG signals. From there, the data is transferred wirelessly and can be processed in real-time to determine a driver's level of drowsiness, for instance. The gurus behind the invention have high hopes for its future, and they've already envisioned it being used in a plethora of medical scenarios and for controlling home electronics. To those about to rock this -- prepare for some serious hat-hair.
New brain control development could help quadriplegics get around
Sure, we've seen brain power used to give mobility back to the immobile, but a new development in Europe is one-upping current efforts by adding in a hint of artificial intelligence to the tried and true brain-computer interface. The MAIA BCI not only converts signals emitted by the brain into actions -- such moving a wheelchair forward -- it also thinks for itself when needed in order to assist the user in getting where he / she wants to go. Essentially, the individual need only think about going left or forward (for example), and the machine itself will automatically detect obstacles and potential barriers in order to move more efficiently. As it stands, there's still quite a bit of testing to be done before MAIA-based wheelchairs would be available to the public, but researchers are already hoping to integrate said technology into artificial limbs and the like.[Via Physorg]
Brain2Robot project creates EEG-controlled robot arm
Thought-controlled appendages are far from new, but an international team of researchers have apparently created an apparatus that aims to make the lives of paralyzed individuals a tad easier. The Brain2Robot project utilizes electroencephalograph (EEG) signals in order to give patients the ability to control a robotic arm, which could eventually be used to do everything from hold periodicals to lift a cup of coffee. Reportedly, the arm could be ready for commercial use within just a few years, but there's no mention of an expected price range. Granted, we'd be a bit more excited about all of this if the technology were somehow made mobile, but it's hard to kvetch about a helping hand, regardless.[Via Primidi]
G-Tec's thought control hat
Hey you. Yeah, you, listen in close; we've seen the future here at CeBIT. If you thought that the idea of controlling your gaming rig with only your mind was just a bit too Tomorrowland, then you haven't laid eyes on the "brain-computer interface" developed by Austria's Guger Tecnologies (g.tec). We're happy to report that in a game of thought-control vs. Engadget man-editor, we were totally pwned at Pong. 10-to-4 if you must know. Our competition sat smug in his stool thinking about where he wanted his paddle to go, as we flailed about helpless with mouse and keyboard in a wake of alpha waves. At least we didn't have to smear gel on our scalp and wear a funny hat -- ha! The system works by cleverly measuring fluctuations in electrical voltage in the brain and then translating them into computer commands. The technology has already been commercialized into the size of an iPAQ Pocket PC for hospitals and research institutes. It costs about $5,000 with a 99 - 100% level of accuracy for "trained subjects." We had our hat handed to us by a person who just started using the system, yesterday. Hell, that's a shorter learning curve than Graffiti. Although the technology shows great promise in controlling prosthetics and assisting the disabled with communications, we found ourselves (and our new best scientist friends, Christoph Guger and Ingo Niedermayer) eagerly discussing its use as a Second Life controller and of course, in robotics.

Neurochip acts as a second motor cortex
Haven't you ever wished that you had a second motor cortex? If you've suffered a brain injury of some kind, you just might. For the last few years, researchers at the University of Washington have designed and installed a special computer chip attached to the top of monkeys' heads to record the brain's motor cortex nerve signals. This computer chip, dubbed the Neurochip, creates a brain-computer interface that records every movement sent from the motor cortex to the rest of the monkeys' bodies. Then the Neurochip converts those signals into a stimulus that can be fed back to the brain, creating new neural pathways that theoretically could be used if the motor cortex was damaged in some way. We've still got a few questions, like exactly how this happens, how big physically this interface is, and when we should expect human trials. Of course, we've seen previous brain-computer interfaces before, but this one seems a bit more practical than strapping your head to some type of computer. The team published its results in the November 2, 2006 issue of Nature.
Teenager plays Space Invaders with only his brain
While having a robotic assistant play video games for you might sound novel, it's certainly not as thrilling as interacting with the 1s and 0s yourself. A team of researchers, engineers, and students at Washington University in St. Louis have crafted a brain-computer interface system that allowed a 14-year old gamer suffering from epilepsy to cruise through the first two levels of Space Invaders using only his imagination. Rather than picking up an Xbox 360 and perusing through the Xbox Live Arcade, the crew went back to their roots and programmed an Atari 2600 to interface with the brain-sensing apparatus. The headgear boasted a grid of sensors that monitored "electrocorticographic activity" from the brain's surface to detect signals based on thought processes that were going on. By calibrating his thoughts with video game triggers, the teenager was able to learn the ropes "almost instantaneously," and had no qualms demolishing the competition while twiddling his thumbs. The group plans to use this successful experiment to further understand the mysterious signals of the mind and give physically disabled individuals a chance to show of their mental sharpness, but we're hoping to see this thing bundled in with the sure-to-be-delayed PlayStation 8 that should hit shelves sometime before 2040 2050.[Via MedGadget]
Mind-controlled PONG featured at CeBIT
Brain-computer interfaces hold enormous promise for perfecting prosthetics, assisting quadriplegics, and improving vehicle safety. So what's the first application shown off at the CeBIT 2006 show? A way of playing (and losing) a game of PONG... with - your - mind.Sure, you could also check out a typing application that's still in the pre-beta-alpha stage below (man, typing on a post on that would take... a very long time), but playing an ancient arcade game with no hands seems like a more entertaining proposition at this point.See also: The Berlin Brain-Computer Interface from Dr. Klaus-Robert Müller A short video clip of that brain-typing application A look back at Joystiq posts featuring the word "PONG" 5.46 GHz PC shown at CeBIT Japanese doctors recommend Brain Training for seniors
