Method:
By giving some of my peers a short test involving the exposure to a series of randomly ordered images, I recorded some brain activity [presumably some from the actual perception of the image .. and some from ?] and then overlayed all of the readings for a particular image into a visualization.
Findings:
The tool [neurosky] definitely had its issues in providing steady data. With this small sample of subjects, a correlation between any sort of brain activity and an image could not be determined.
However, the visualizations show that the data varied from image to image. The visualization was made in processing using some simple commands to vary the placement of a Koch curve over time. The interesting outcome from all of this was the large variation in the visuals resulting from different sets of data going through the same algorithm.
*note: definitely not a controlled scientific experiment as much an visual generator.
