DARPA (US Defense Advanced Research Projects Agency) wants to crowdsource cheap brain-computer interfaces

The US Defense Advanced Research Projects Agency wants the DIY (or Maker community) to develop inexpensive brain-computer interfaces according to a Sept. 27, 2013 news item by John Hewitt on phys.org,

This past Saturday [Sept. 21, 2013], at the Maker Faire in New York, a new low-cost EEG recording front end was debuted at DARPA’s booth. Known as OpenBCI, the device can process eight channels of high quality EEG data, and interface it to popular platforms like Arduino. …

DARPA program manager William Casebeer said that his goal was to return next year to the Maker meeting with a device that costs under $30.

Adrianne Jeffries’ Sept. 22, 2013 article for The Verge provides more information (Note: Links have been removed),

A working prototype of a low-cost electroencephalography device funded by the US Defense Advanced Research Projects Agency (DARPA) made its debut in New York this weekend [Sept. 21 – 22, 2013], the first step in the agency’s effort to jumpstart a do-it-yourself revolution in neuroscience.
There are some products like those in the Neurosky lineup, which range from $99 to $130. But most neural monitoring tools are relatively expensive and proprietary, the OpenBCI [OpenBCI, an open source device built to capture signals from eight electrodes at a time] team explained, which makes it tough for the casual scientist, hacker, or artist to play with EEG. If neural monitoring were cheap and open, we’d start to see more science experiments, art projects, mind-controlled video games, and even serious research using brainwaves. You could use an at-home EEG to create a brain-powered keyboard, for example, Dr. Allen [Lindsey Allen, engineer for Creare;  OpenBCI was built by Creare and biofeedback scientist Joel Murphy, and the prototype was finished only two weeks ago] said, and learn how to type with your mind.

I have written about various brain-computer interfaces previously, the most recent being a Dec. 5, 2012 posting about Muse, a $199 brainwave computer controller.

A brainwave computer controller named Muse

Toronto-based (Canada) company, InteraXon has just presented a portable brainwave controller at the ParisLeWeb 2012 meeting according to a Dec. 5, 2012 article by Nancy Owano for phys.org,

A Canadian company is talking about having a window, aka computer screen, into your mind. Another of the many ways to put it—they believe your computer can be so into you. And vice-versa. InteraXon, a Canadian company, is focused on making a business out of mind-control technology via a headband device, and they are planning to launch this as a $199 brainwave computer controller called Muse. The company is running an Indiegogo campaign to obtain needed funds. Muse is a Bluetooth-connected headset with four electroencephalography sensors, communicating with the person’s computer via the Bluetooth connection.

Here’s more about the technology from InteraXon’s How It Works webpage,

Your brain generates electrical patterns that resonate outside your head, which accumulate into brainwaves detectable by an Electroencephalograph (EEG). The EEG can’t read your thoughts, just your brain’s overall pattern of activity, like how relaxed or alert you are. With practice you can learn to manipulate your brainwave pattern, like flexing a muscle you’ve never used before.

InteraXon’s interface works by turning brainwaves into binary (ones and zeros). We’re like interpreters fluent in the language of the mind: our system analyses the frequency of your brainwaves and then translates them into a control signal for the computer to understand.

Just like a button or switch can activate whatever it’s connected to, your translated brainwaves can now control anything electric. InteraXon designers and engineers make the experience so seamless, the connected technology seems like an extension of your own body.

It would be nice to have found a little more technical detail.

InteraXon is currently featuring its work at the 2010 Olympics in Vancouver (Canada) as an example of past work,

When visitors arrive at Bright Ideas, InteraXon’s thought-controlled computing experience custom designed and built for the 2010 Olympics, they are lead to their own pod. In front of each pod is a large projection screen as well as a small training screen. Once seated, a trained host hands them a headset that will measure their brain’s electrical signals.

With help from the host, the participants learn to deliberately alter their brainwaves. By focusing or relaxing their mind, they learn to change the display on their training screen; music and seat vibrations provide immediate feedback to speed the learning process to five minutes or less. Now they are ready for the main event.

Thoughts are turned into light patterns instantaneously as their brain’s digital signal is beamed over the Rocky Mountains, across vast prairies all the way to three major Ontario icons – a distance of 3000 km.

This project – a first at this grand scale – allows each participant to experience a very personal connection with these massive Ontario landmarks, and with every Canadian watching the lightshow, whether online, or in-person.

As for Muse, InteraXon’s latest project, the company has a campaign on Indiegogo to raise money. Here’s the video on the campaign website,

They seem very excited about it all, don’t they? The question that arises is whether or not you actually need a device to let you know when you’re concentrating or when your thoughts are wandering.  Apparently, the answer is yes. The campaign has raised over $240,000 (they asked for $150,000) and it’s open until Dec. 7, 2012.  If you go today, you will find that in addition to the other pledge inducements there’s a special ParisLeWeb $149 pledge for one day only (Dec. 5, 2012). Here’s where you go.

The Canadian Broadcasting Corporation’s Spark radio programme featured an interview (either in Nov. or Dec. 2012) with Ariel Garten, Chief Executive Office of InteraXon discussing her company’s work. You can find podcast no. 197 here (it is approximately 55 mins. and there are other interviews bundled with Garten’s). Thanks to Richard Boyer for the tip about the Spark interview.

I have mentioned brain-computer interfaces previously.

Less confused about Europe’s FET (Future and Emerging Technologies programme)

I’ve had problems trying figure out the European Union’s Future and Emerging Technologies programme and so I’m glad to say that the Feb. 10, 2012 news item on Nanowerk offers to clear up a few matters for me (and presumably a few other people too).

From the news item,

Go forth and explore the frontiers of science and technology! This is the unspoken motto of the Future and Emerging Technologies programme (FET), which has for more than 20 years been funding and inspiring researchers across Europe to lay new foundations for information and communication technology (ICT). [emphasis mine]

The vanguard researchers of frontier ICT research don’t always come from IT backgrounds or follow the traditional academic career path. The European Commission’s FET programme encourages unconventional match-ups like chemistry and IT, physics and optics, biology and data engineering. Researchers funded by FET are driven by ideas and a sense of purpose which push the boundaries of science and technology.

They have three funding programmes (from the news item),

To address these challenges, the FET scheme supports long-term ICT programmes under three banners:

  • FET-Open, which has simple and fast mechanisms in place to receive new ideas for projects without pre-conceived boundaries or deadlines;
  • FET-Proactive, which spearheads ‘transformative’ research and supports community-building around a number of fundamental long-term ICT challenges; and
  • FET Flagships, which cut across national and European programmes to unite top research teams pursuing ambitious, large-scale, science-driven research with a visionary goal.

The news item goes on to describe a number of projects including the GRAPHENE-CA flagship pilot currently under consideration, along with five other flagship projects, for one of two 1 Billion Euro prizes. I have commented before (my Feb. 6, 2012 posting) on the communication strategies being employed by at least some of the members of this particular flagship project. Amazingly, they’ve done it again; theirs is the only flagship pilot project mentioned.

You can see the original article on the European Union website here where they have described other projects including this one, PRESENCCIA,

‘Light switches, TV remote controls and even house keys could become a thing of the past thanks to brain-computer interface (BCI) technology being developed in Europe that lets users perform everyday tasks with thoughts alone.’ So begins a story on ICT Results about a pioneering EU-funded FET project called Presenccia*.

Primary applications of BCI are in gaming/virtual reality (VR), home entertainment and domestic care, but the project partners also see their work helping the medical profession. ‘A virtual environment could be used to train a disabled person to control an electric wheelchair through a BCI,’ explained Mel Slater, the project coordinator. ‘It is much safer for them to learn in VR than in the real world, where mistakes could have physical consequences.’

So, PRESENCCIA is a project whereby people will be trained to use a BCI in virtual reality before attempting it in real life. I wish there was a bit more information about this BCI technology that is being developed in Europe as I am deeply fascinated and horrified by this notion of thought waves that ‘turn light switches on and off’ or possibly allow you to make a phone call as Professor Mark Welland at Cambridge University was speculating in 2010 (mentioned in my April 30, 2010 posting [scroll 1/2 way down]). Welland did mention that you would need some sort of brain implant to achieve a phone call with your thought waves, which is the aspect that makes me most uncomfortable.
