OK here goes. A brief time ago we recorded real-time EEG while a person walked and shopped in a grocery store. An abbreviated version of the movie can be seen here.

As you can see, besides the large frame showing what the person is oriented towards (although there is no eye-tracking) the smaller right hand frame displays a flurry of brain activation. Basically, this shows alpha-band activation, and the source localization is done by algorithms on a Nokia N900 smartphone.

The aim of this movie was a proof-of-concept approach. We were able to demonstrate that we can use this approach, we have sufficient signal for appropriate analysis, and at  the same time we made some nice public appearance in the Danish national broadcast company.

Now, the time is ready for more scrutinizing research, and through coming blog posts, I will let you in on this approach. Basically, although we were able to make cool brain signals in the store, there are still many important issues to be resolved, including:

  • finding a suitable set-up – this is probably the smalles of problems; one could compare different conditions (picking an object and putting it down again vs picking an object and putting it in the basket), or even states (women’s level of alpha band activation while in the grocery store vs the shoe store…)
  • minimizing noise – although much can be done with noise reduction algorithms, there is still a need for starting off with a stationary set-up with a higher degree of control over signals, and then move out of the lab
  • identifying neural predictors of …. (purchase, attention, memory, … fill in the blanks) – also done best first in the lab, and then moved into the mobile settings
  • being creative – the tool can be used for so much more than in-store decisions. Imaging using it at the museum, at the casino, when driving a car, for patients studies, at the trading floor….!!!!

    Good day! Do you know if they make any plugins to help with
    SEO? I’m trying to get my blog to rank for some targeted keywords but I’m not seeing very good gains.

    If you know of any please share. Thank you!

    I am a victim of the brain initiative. It is the implanting of a microchip to enable torture. They are violent, raping, maiming, sodomizing Newport News and Virginia State Police. They implant you and use the “nerve stimulator” to keep in in constant pain, sleep deprivation, heart attacks and other inhuman unGodly torture. I believe it to be the mark of the beast. They are the childrent of Satan and they are preparing for the anti-Christ. They call it rape and sodomy – they know how it feels and they do it repeatedly. They call it giving me the beat down of a life time. The hopitals call it sleep deprivation and heart attack. They pulse energy projectiles at your body. Virginia State Trooper Jared Vance told my clients they use laser to come through the electronics. They create laser induced plasma channels and fire neurons and nerve endings. Walter Reed has already done this in 1993. Dr. Stephen Cunningham, Virginia Beach Psychiatric Center, told me this was all a state police setup. It enables law enforcement to see through your eyes what you see and hear what you hear. It is truly just for ubiquitous surveillance. Read Springer’s book “Safeguards in a World of Ambient Intelligence”. It discusses how to read minds remotely. It is a gross violation of my constitutional rights and human rights. There are laws in Virginia that ban implantation of microchips, Federal laws against torture, and National Institute of Health requires informed express knowlege and consent. Virginia is using it’s innocent citizens as a fund raiser. It is criminal rico. The Commonwealth Attorney and the Attorney General are participating in the torture. Monday, the police left a dozen microphone with antennas eavesdropping bugs on my kitchen counter. They told the judge there was no criminal investigation of me. It is horrible when they comment on your body when you shower. Or if you lift your bottom to wipe, they give you a jolt of electricity to make you fall off the toilet. They are truly evil men and women. Their attorneys are participating in the torture. Only one removed herself from the case after hearing me cry out in pain. I have spent a lot of years crying because the pain was unbearable. My own doctors office of 30 years got involved in this criminal rico. Where do you go when there is so much corruption. I am headed to the supreme court. I apologize if there are legitimate brain studies, but I never volunteered to have my life destroyed. I am no longer living my life, I am enduring it!
