Emotiv's headset gives users mind-control over digital objects

Emotiv's headset allows users some control over objects on a computer. It is possible to move things around, with limited application, with your mind.

I've just made a small orange cube disappear with my mind. No hands necessary.

I'm testing out the San Francisco company's so-called brain control interface, the latest iteration of technology it first showed off a year ago, but which, unlike last year, is now almost ready for prime time.

The idea is a blending of hardware and software: A headset that seems a little like the one from the James Cameron-written 1995 film, Strange Days, complete with a set of sensors that are built to read your brain waves.

The software then is designed to interpret those brain waves in such a way as to allow users to manipulate objects onscreen with nothing but their mind.

So that's why I've come to this office in downtown San Francisco, where I'm face-to-face with this little orange cube. It's kind of mocking me, daring me to make it disappear.

The headset is designed to fit snugly on a user's head. The data it produces can, in theory, be plugged into a wide variety of software.

Here's how it works: The software has several choices for actions you can take. So, taking the disappearing cube as an example, once you're hooked up to the headset, you're directed to run a short, six-second test, where you concentrate on doing something, anything, with your mind--relax, focus, whatever.

Then, once you've completed the test, it's you against the cube. And the challenge is to see if you can reproduce what it was you were doing with your mind during the test; If so, the cube slowly disappears.

In my case, it disappeared, then came back, then disappeared again and then came back. Repeat.

They also ran me through another example, this time trying to pull the cube forward. This one was harder because the brain function I chose to do to synchronize with the challenge was more concentrated. It involved me sort of tensing up my head and imagining the act of pulling the cube forward. It didn't work very well.

But with the disappearing act, I simply relaxed my mind, with much better results.

Of course, there's no relationship at all between brain activity that is consciously trying to "pull" the cube forward and what happens. That is to say, it doesn't matter in any way what you're doing with your mind, so long as what you do during the six-second calibration matches what you do when you try to enact the action.

So really, the software is just looking for a pattern match. It's not all that complicated a concept, though I'm sure it's a pretty difficult engineering feat.

Emotiv has also built technology designed to read your facial expressions and emotions. So while there, I saw a demonstration where someone wearing the headset would smile, frown, smile again, and so forth. And a goofy-looking face on the monitor would repeat the expression.

For now, this is all still just in prototype phase. But Emotiv promised me that the headset would be available in time for Christmas this year, at a price of $299. It'll come bundled with a game that is geared toward using the technology, and presumably, more games will follow. The success, I think, of this product, will be how easy it is for developers to build the technology into their games. And that, presumably, is why the product is being showcased during this week's Game Developers Conference, here in San Francisco.

Emotiv also said that the company is working on a partnership with IBM to integrate the brain control interface technology with Big Blue's virtual worlds projects.

To be perfectly honest, I think this technology is a ways from being ready for any hard-core application. Based on what I saw, it's very interesting and even quite impressive. But I just don't know if it can improve fast enough to make a real difference in the market in the next year. Perhaps it can, and if so, that would be fantastic.

Nintendo's Wii and Guitar Hero have opened people's eyes to all-new interfaces, and I'm sure that this would fit into that category. But the things that have made the Wii and the Guitar Hero controller so successful is that they are easy and intuitive to use. Whether Emotiv's technology is as well is something I'd have to reserve judgment on.

Still, I was able to make that cube disappear without using my hands. And that's something.

Does this technology worry anyone else?

It seems troublesome to me that they are making progress in reading brain activity. Maybe at some point nothing will remain private anymore.

Amazing potential for severely handicapped
by msui772 February 25, 2008 2:52 AM PST
This amazing technology may eventually prove a viable alternative for those who, like Stephen Hawking, are severely handicapped but need an interface to a computer to communicate or control their environment! Wow!

I wanted this until I gave it some thought...

This would be great until the first time the cube is replaced by another image when your boss walked in and you started thinking about throwing stuff at them or that hot co-worker walks in and your mind takes a turn towards the gutter. In a split second you violate sexual harassment laws and company computer use policy. Bad Bad Things. :)

This is old stuff
by niieani February 25, 2008 8:20 AM PST
This is relativly old stuff. It's just a written up software for the hardware that existed for years now. In fact, I have a similar device at home, it's called OpenEEG and you can look it up on google. There are quite a few games already that you can control with your mind and you can improve your concentration, learning and relaxation abilities by playing them and practicing. Though the "facial expression" part is new, it doesn't seem like a "must-have" in business applications. EEG's were also used for years in medical business. Their home use started somewhere about year 2000.
