I created TEST PROGRAMME exclusively by myself in order to investigate brainwave activity in different situations as well as familiarize myself with the EPOC headset. I was interested to test different subject brain responses to logical tasks as well as tasks which involved imagination and creative thinking. My aim was to create a set of different situations and by using a vague scientific method approach make observations and draw conclusions based on the gathered data. I am not following strictly scientific method but using some elements of it, such as: running tests (experiments), gathering and analyzing data, drawing conclusions and reporting results. My tasks purely consisted of testing EPOC headset with few individuals and then sum up the results.

I used available software (EPOC Control Panel, Mind Your OSCs) in order to gather and read data. I also created a custom built programs (Max/MSP, Processing) in order to transmit data using an OSC protocol and display it into visual graphs. The brainwave electric current data was transmitting continuously in real time therefore capturing out-coming data into still visual layout was crucial in order to conduct any further analysis. The graph displays brain activity recorded over 1 min period of time.

There are total number of 5 different emotional responses such as:

  • Engaged/Bored
  • Excitement
  • Excitement Long Term
  • Meditation
  • Frustration

The software I am using is registering a brain activity into these 5 categories mentioned above. I am measuring and recording each individual’s brain response to TEST PROGRAMME across these 5 categories defined by developers of the headset. An article on Wikipedia reports that “the names may not perfectly reflect exactly what the emotion is.” Wikipedia article, 2012. Emotiv Systems. [online] Available at: <http://libweb.anglia.ac.uk/referencing/harvard.htm&gt; [Accessed 20 March 2012].I will be taking it into consideration when summarizing results and focusing more on detecting brain activity patterns rather than defining what they could signify in any expressive form.

I did alter original questions a little bit and i decided to remove the last question due to its inappropriate nature. It sounded discriminating about sexuality and intimidating as a whole task so i decided to get rid of it.

Here are the updated questions i used throughout the TEST PROGRAMME:


Questions and tasks.

  1. Sit calm and relaxed with eyes closed. No stimuli.

  2. Sit calm and relaxed with eyes opened.

  3. Let the subject answer these questions:

    1. What is your name and surname?

    2. How old are you?

    3. What year is it now?

    4. Where are we?

    5. What colour is sugar?

  4. Let the subject answer these questions:

    1. How would you describe the taste of the concrete?

    2. Describe the feeling of having a tail?

  5. Ask the subject to imagine following situations with eyes closed:

    1. Swimming in the ocean at night.

    2. Continuously falling down from a tall building.

    3. Sitting in the field full of flowers.

  6. Ask the subject to imagine following situations with eyes closed:

    1. Being a huge colourful giant with long legs and flying.

    2. Being in the horror story and fighting zombies.

    3. Imagine pure bright light, nothing else.

  7. Ask the subject to perform mathematical calculations on the paper:

    1. 2+2=

    2. 32-12=

    3. 40/7=

    4. (1378/3)+(6382/12)=

  8. Ask the subject to sing a chosen song. Record it.

  9. Ask the subject to listen to the song (Bob Marley “Jammin’”)

  10. Playback recorded song to the subject he/she just sang.

  11. Ask the subject to draw:

    1. An apple.

    2. A death.

    3. A self-portrait.

12.  Ask the subject to stand up and fall back into someone’s arms with eyes closed.

13.  Dance to any chosen song.

I did compile a folder which contains all of the readings of my 6 testing subjects and it reflects on the whole TEST PROGRAMME. I also included conclusion section on each of them to explain what i have learned more from it.

The most important thing what i have learned out of this research is that every single person reacts to same situations totally different. There are some similarities in brain readings but very roughly sketched out. The individual inputs are always significant to particular person. In order to make any assumptions i would have to test it with much more people and then withdraw some general conclusions, and even then, i think that would be too daring of assumptions to make about people. it is impossible to put people in boxes and expect all of the belonging parties will react to a scripted brain activity. Every single individual reacts individually due to life experiences, condition of the brain and personality.

After conducting all of these tasks i have made another conclusion that it has helped me greatly to understand how the EPOC device works. That gave me important tips of how to wire the final visual projection. By knowing the type of emotions headset can detect i will be able to apply it on to generative visual body.
