Muse brain-sensing headband thoughts-on (video)
Plenty of companies are experimenting with thought-reading gadgets, and in the cluttered South Hall here at CES, we came across the folks from InteraXon showing off their Indiegogo-funded "Muse brain-sensing headband." It measures EEG signals from four forehead sensors and two tucked behind the ears, and sends those brain measurements to other gear via Bluetooth. InteraXon has developed an app suite for mobile devices to showcase the headband's capabilities, including thought-controlled games and brain tracking, exercise and fitness software for improving cognitive function, memory, attention and for reducing stress. That'll come bundled with any purchased units, but an SDK is also available for third-party developers to explore other possibilities. They had a demonstration set up on the show floor, so we thought we'd sit down and take it for a spin. The headband was flexible and surprisingly comfortable, and with a bit of fiddling, we were good to go. One monitor showed brain activity on a couple of complicated graphs, while a scene on a second monitor grew busier as our concentration increased. Watching one graph react to blinking was pretty cool, and once concentration levels reached over 85%, it started to snow on the animated scene. While this obviously isn't very relevant to any potential applications, it was fun to watch the hardware clearly working as intended. You can check out our shots of the headband in the gallery, or check out the video of us trying it out below. Unfortunately we were only allowed to use it for a limited time -- the demonstration was in danger of breaking due to this editors' massive brain. Kevin Wong contributed to this report.
Monkeys control virtual arm with their brains, may herald breakthrough for paraplegics
Monkey mind-controlled arm: It sounds like the name of an awesomely terrible sci-fi film or a fledgling grindcore group, but it's a very real phenomenon, and one that could pay significant dividends for paraplegics everywhere. Neurobiology professor Miguel Nicolelis and his team of researchers at Duke University recently devised a method by which monkeys (and, perhaps one day, humans) can control a virtual arm using only their brains. It's a concept similar to what DARPA has been pursuing with its mind-controlled "Luke" arm, with one important difference: Nicolelis' system not only allows users to remotely execute motor functions, but provides them with near-instantaneous sensory feedback, as well. Most similar techniques use electrode implants to stimulate brain activity, but this can create confusion when a patient's brain sends and receives signals to and from a prosthetic arm. Nicolelis circumvented this problem with a new interface that can read and transmit brain signals to an artificial limb, before switching to a receptive mode in just milliseconds. After designing the technology, Nicolelis and his colleagues tested it on two, electrode-equipped rhesus monkeys. One set of electrodes was placed in the motor cortex of each animal, with the other implanted within their brains' sensory regions. They then trained the monkeys to look at a three identical objects on a computer screen and to "touch" each object with a virtual arm, controlled by signals sent from the brain electrodes. Only one of the three objects had a so-called "virtual texture," which, if selected with the on-screen arm, would send a sensory signal back to the monkey's brain (while triggering a tasty squirt of fruit juice for the lucky contestant). The two rhesus species ended up passing the test with flying colors, resulting in a "proof of principle" that Nicolelis' system can send tactile signals to the brain in almost real-time. The scientists have already developed a way for monkeys to control the arm wirelessly, and are now embedding their technology within a full-body, mind-controlled exoskeleton for paralyzed patients, as well. Of course, the technology still needs to be tested on actual humans, though Nicolelis seems confident that he and his team have already cleared the most difficult hurdle: "Since we cannot talk to the monkeys, I assume with human patients, it's going to be much easier."
Toyota Prius Project's concept bike lets you shift gears with your mind
Got mind control on the mind? Check out this new concept bike from Deeplocal -- a Pittsburgh-based design house that's adding a neurological twist to the art of cycling. As part of Toyota Prius Project No. 11, the company outfitted the seat post of a Parlee PXP aero road bike with a wireless transmitter, allowing users to remotely shift gears with a smartphone. Deeplocal's designers then added a set of neuron transmitters to a helmet and re-programmed the PXP to communicate with them -- meaning, in theory, that riders could control the bike's gears by simply thinking about it. Theory, of course, isn't the same thing as practice, but perhaps the concept will become a reality if we think really hard about it.
AMO Arm pneumatic prosthetic does mind-control on the cheap
We're no strangers to amputees moving stuff with their minds -- for that matter, a thought-controlled prosthetic isn't really new to us, either -- but the pneumatic arm you see here isn't like other intelligent limbs. Unlike most mind-operated prosthesis, the Artificial Muscle-Operated (AMO) Arm doesn't require invasive surgery, and according to its inventors, it costs a quarter of the price to make. Here's how the thing works: the host human wears a headset that sends brain signals to a chip in the arm that then matches those signals to a database of related actions, triggering a series of pneumatic pumps and valves to move the limb. Thus, if the wearer thinks 'up,' the arm moves up. The AMO Arm's creators, a pair of undergraduate biomed students, say that not only is their invention a steal to produce, but it also takes just minutes to acclimate to, which has us wondering, do you have to be missing an arm to get a hold of one of these things? You know, we can always use an extra hand. Full PR after the break.
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.
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]
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]
NeuroSky and Square Enix set to demo mind-controlled gaming
The last time we saw NeuroSky's MindSet brainwave-controlled gaming headset, the company was partnering with Sega -- now the peripheral-maker has teamed with Square Enix to produce what we hope will be a "mind-blowing" (groan) demo at this year's Tokyo Game Show. If you'll recall, NeuroSky has been pushing its unique brand of mind-controlled gaming since way back in 2005, but it appears the technology has become increasingly attractive to notable game-makers as of late. On Thursday, the two companies plan a demonstration of the in-game powers of relaxation at TGS in what appears to be a perfect example of Neo-like godliness. The whole thing goes down October 9th, so be there or be Square. Enix.
