Brain wave meter knows what you're thinking, so get your mind out of the gutter (video)
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.
Cornell students steer Pong using brain waves, can't quite play during naps (video)
We here at Engadget are always fans of brain wave experiments, and so we were delighted when two Cornell University electrical engineering students, Chuck Moyes and Mengxiang Jiang, wrapped up a final project using brain waves in the best way possible: playing Pong. Their experiment links a baseball cap full of EEG-scanning electrodes to a computer, letting the cap wearer control a paddle using Alpha or Mu waves. Depending on the waves you use, you can move the paddle either by changing your concentration level or by thinking about moving your feet. You won't rack up a high score while napping (or with a teammate narrating over your shoulder), but with a budget under $75, it's hard to find fault. You can grab the source code below, and check out a video of Jiang and Moyes' handiwork after the break. [Thanks, Chuck and Mengxiang]
Haier Brain Wave TV mind-on
We'd all love to be able to control stuff with our minds and seeing as Haier's 58-inch Brain Wave TV was at CES we had to try. To use the mind control, you have to snap a controller on your head which attaches to your earlobe and with a small metal pad on your forehead. Unfortunately, this time around, we couldn't interface with the set to change channels and adjust volume and such but there was a game where you try to fly a bird through a maze. How'd we do? Well, we made the bird float up and down but that's about all. So, for those of you with dreams of never again having to relinquish the remote control because you're wearing it, keep dreaming. Video and pics below the break.
Haier's mind control TV prototype hits IFA, we go foreheads-on (video)
The remote control revolutionized the way we watch television, doing away with the need for frequent trips to the set in order to change channels. One prototype in Haier's portfolio makes the whole remote thing look like a back breaking chore by comparison. The Brain Wave (definitely not a final product name) television protoype showcased at IFA this week brings mind control into the picture, promising users a future where channels can be changed and volume controlled with mere thought. The set is still in the early prototype stages at the moment, however, so we're still a ways away from such life altering precision. At the moment, the only available demo involves blowing up an animated barrel with your mind. Naturally, we had to give the thing a spin. Check out the results after the break.%Gallery-132589%
KDDI's mind-reading Android app monitors your brainstorms, or lack thereof... (video)
Ready for an epic brainwave dance-off between Jobs' Jets and Rubin's Sharks? Well, put down your shivs and get back to that alpha state because it's gonna take a little while. Developed by KDDI's R&D labs, this prototype mind-monitoring, sensor-laden headband connects wirelessly to your Android device to let you know just how stressed out you are. All it takes is a simple 30-second game of "mash mash mash the little green robot" (amongst others) to translate your focused and relaxed states into an easily readable brain pattern chart. The tech's nothing we haven't already seen the ominously named NeuroSky do for the iOS platform, but it should help to get those fanboy flames a-blazing. Of course, if mobile OS turf wars don't get your neurons in a tizzy, you could always spend half a minute thinking of your honey -- or actual honey. Whatever floats your neural boat. Video demonstration after the break.
XWave lets you control your iPhone with your noodle, levitate if you're lucky
In the early, chaotic, primordial years of the mobile phone era, you had to press real, actual "buttons" to get things done. Almost barbaric to think about now, isn't it? As society advanced and we gradually became a more civilized species, buttons gave way to touchscreens and voice control, mercifully giving the atrophied sausages we call "arms" and "fingers" a bit of respite every time we needed to surf through cyberspace, place a phone call, or send a text message. Now, it seems the evolution of Homo sapiens is reaching its inevitable final stage with the release of the PLX XWave, headgear that plugs into your iPhone, iPod touch, or iPad and -- after a bit of training -- lets you control the device with your mind alone. As you might expect, the headset makes use of the NeuroSky technology that we've seen several times through the years and will be made available with a number of apps upon its release next month including a game, dedicated training app, a music controller (which will let you compare brainwaves with other XWave users, interestingly), and an "Om Meditation Timer." If none of those titles have captured your imagination, you'll be able to write your own apps with the device's SDK; needless to say, we'll be patiently waiting for the levitation app depicted here. Orders are online now for $100 with delivery in October.
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.
