Neurocam Automatically Records Only What You’re Interested in

Posted on by

The Neurocam is the latest invention from Neurowear – the minds behind the Necomimi cat ears and that tail that wags tail that wags based on your thoughts. Though this one seems like a slightly more useful, if not still strange device.

The Neurocam monitors brainwave activity to monitor your interest level in things you’re observing. When it senses that your interest threshold has been hit, it automatically captures images or video. In its current state, the system automatically creates 5-second GIFs of interesting subjects. Here’s a brief video demo of the Neurocam in action:

The device is a headband that holds the users smartphone in a bracket, and it appears that it also has some sort of 90-degree lens adapter for the smartphone so it captures images of whatever you’re looking at.

It’s definitely a novel idea, but all I can imagine is that for most guys, the Neurocam is only going to capture images of cleavage and butts.

Samsung explores touchless tablet interaction with brainwave technology

Samsung explores touchless tablet interaction with brainwave technology

Try and wrap this one around your noggin. Samsung is currently working with researchers at the University of Texas on a project involving EEG caps that harnesses the power of one's mind to control tablets and smartphones, and if that weren't enough, the company's actually hoping to take it mainstream. Now, before we get too far ahead of ourselves, let's be clear: in its current stage, the system is cumbersome and aimed at those with disabilities, but Samsung's already proven that it's interested in alternative input methods, and this could certainly be the logical conclusion.

As is, participants are asked to wear EEG caps that measure the electrical activity along their scalp. Then, they're able to make selections by focusing on an icon that flashes at a distinct frequency from others, which the system recognizes as a unique electrical pattern. Overall, the accuracy of the system is in the ballpark of 80 to 95 percent, and users are able to make selections on average of every five seconds. In order to make the system more approachable, the researchers hope to develop EEG hats that are more convenient and less intrusive -- in other words, ones that people can wear throughout the day. We can't promise this type of futuristic tech will come anytime soon, but for a closer peek, hit up the source link for a peek at Samsung's next wild idea.

Necomimi cat ears’ creators branch out into brain-controlled headphones (video)

While we've always thought that brain-controlled cat ears are a perfectly viable business model, it's usually in a company's best interest to diversify, in case, you know, the bottom ever drops out of the furry accessory market. Neurowear, the company behind the Necomimi, which provided some of the more memorable moments at this year's CES, showed off its latest project, the Mico, which continues the company's core competency of letting people do stuff with mind waves. In this case, it's music control. A big white pair of headphones are connected to a sensor that rests on your forehead and a dangling clip for your earlobe (a la the Necomimi).

The cans connect to your smartphone via Bluetooth, using your current mood to select a song from the company's app, which currently contains about 100 tracks. According to the company, the songs have been "neuro-tagged," based on its testing, to ensure that they match up to perceived mood. If your mood changes, just give the phone a shake and it will clean the musical slate Etch-a-Sketch-style.

Duke melds two rats’ minds through the internet, Spock may not approve

Duke University melds two rats' thoughts over the internet we're not sure Spock would approve

Some would say the internet already lets us share every minute detail of our thoughts, much to our followers' dismay. Duke University isn't deterred by our behavior -- if anything, it just took oversharing literally by connecting two rats' minds in an experiment, first in a lab and ultimately online. Electrodes attached to the brain of a host "encoder" rat in Brazil processed the motor-oriented mental activity for a desired behavior, such as pressing a lever on cue, and converted it into a signal that was then received by a "decoder" rat as far away as Duke's US campus. The majority of the time, the decoder rat performed the same action as the encoder. Researchers also found that rewarding the encoder alongside the decoder created a virtuous loop, as treating the first rat for a job well done focused its attention and improved the signal strength.

We're not sure that Vulcans would endorse this kind of mind meld, though: apart from immediately depriving the decoder rat of self-control, prolonged testing led to the same rodent developing additional sympathetic reactions to the encoder. There's also concerns that the test was too binary and didn't reflect the complexity of the whole brain. All the same, Duke's study is proof enough that we can export brainwaves in a meaningful way.

PLX’s XWave Sport gives brainwave interfaces a casual look, triggers ’80s flashbacks

PLX's XWave Sport gives brainwave interfaces a casual look, triggers '80s flashbacks

Brainwave-guided interfaces are common. Most of the time, though, they're not what we'd call subtle. PLX Devices hopes to have that licked through the XWave Sport, a brain interface that disguises all its sensors through a fuzzy, exercise-friendly headband. Underneath the incredibly 1980s-retro (but washable!) look, you'll get about six hours per charge of tracking for concentration, relaxation and other noggin-related data that can transmit over Bluetooth to apps for Android, iOS or old-fashioned PCs. An SDK is available now, but pre-orders for the $100 XWave Sport won't ship until September 20th. That should give us enough time to perfect our Flashdance reenactments.

Axio’s EEG headband helps you teach your brain to focus (hands-on)

Axio's EEG headband helps you teach your brain to focus handson

Usually when an EEG sensor headset graces these pages, it's used to peer into your thoughts or grant the wearer the power to control other gadgets with his or her mind. While such uses have appeal, start-up company Axio has a new EEG headband that aims to help you learn to better control your own brain. It tracks your level of mental focus in real-time and provides positive reinforcement audio feedback when you're mentally locked in. The neoprene band packs a trio of electrodes, a PCB with a Bluetooth radio and audio out, and a battery pack to power everything. It works by identifying the brainwave readings that correlate to ideal executive function in your pre-frontal cortex and shooting that data to your computer or phone via Bluetooth. Axio's software then shows an onscreen graph that charts your focus level in real-time, and for folks who prefer a more literal tracking method, there's a photo above the chart that moves in and out of focus along with your mind. Additionally, the headband provides pleasing audio neurofeedback when you're focused in order to train you to stay mentally engaged.

Unfortunately, we couldn't get much more information about the neurofeedback functionality, as the technology behind it is the company's secret sauce, and it won't divulge more until it's got the cash to bring the band to market. We also weren't able to actually test the band to see how it works, as it's still in the prototype phase and there's still a kink or two left to work out. Axio did tell us that the prototype we got our mitts on was the result of just six short months of work, and that after hacking together the original design using Arduino, the current iteration has a custom PCB better suited to Axio's needs. Co-founder Arye Barnehama also informed us that the band should be on sale by the end of summer, though he wouldn't say for how much or where we'll be able to pick one up. Sometime after it hits store shelves, Axio plans to release an SDK so that enterprising devs can make their own focus-aiding software and implement whatever audio feedback they prefer to help them take care of business -- a dose of Bachman-Turner Overdrive ought to do the trick.

Brain wave meter knows what you’re thinking, so get your mind out of the gutter (video)

Brain scanner knows when you are sleeping, knows when you're awake, knows when you've been bad or good so be good for goodness' sake

A team from Keio University has built a brain scanner that knows when you're stressed, sleepy or interested. Resembling John McEnroe's headband, the device examines the frequency rather than the type of waves your noggin produces. That data, combined with the team's algorithm enables your thoughts and feelings to be examined in real time. Advertisers might want to use the tech to learn what holds our interests, but there's probably plenty of better uses we could think of -- you can come up with some yourself when you watch the footage after the break.
