Over the past several weeks we have been working pretty diligently to generate meaningful graphics related to brainwave data on ThinkSuite.io. This is actually pretty difficult to do well, but here is the best version of the graphic we came up with.
These waves are correlated with specific thought/mood patterns, and thus can provide helpful insight. Easy to read, clearly beta waves were higher and more consistent the first half of the experiment, as opposed to the second half. Beta waves are associated with higher order thinking, or conscious thought.
This makes sense, because for the first half of the experiment we were still trying to properly ensure the sensors were working and we were reviewing data.
The second half of the experiment was a simple reading task, i.e. browse Hacker News. During this stage Theta wave activity increased, likely due to the more relaxed and scanning nature. There wasn’t any hard thought going into it.
The increase is definitely less pronounced, but still pretty clear.
The most clear change in brainwave pattern is probably Gamma waves, often associated with higher level thought, but is definitely associated with muscle movement (i.e. moving your arm/leg make the waves go higher).
We will continue to tweak, and if anyone has any suggestions to improve brainwave viewing, please let us know!
We are currently using Google Charts, with data created using either OpenBCI or Emotiv EEG’s.
