Games of Active Life

This project was part of the course Brain Computer Interfacing. The BioSemi was used to measure EEG data. The experiment tested the standard P300 oddball paradigm. The oddball paradigm states that a peak will appear in the EEG signal when someone notices an odd element in a sequence of other elements. A user was seated in front of the computer with a EEG cap positioned on its head. Electrodes were connected to the cap. The user watched a series of images of monkeys and elephants in a frequent-rare ratio of 80-20%. Each image was shown for half a second. The user was asked to count the amount of monkeys. In the second test, the elephant image was replaced by the same monkey image but then vertically rotated. Sadly, data got lost, so no results could be observed. However, it is hypothesized that in the first situation a P300 peak could be seen when the person was watching an elephant and that also a peak could be observed when the person watched the “mirrored” monkey in the second situation.
