You are quite right. I am also not such an expert about EEG, but I will have to. Meanwhile I think I have found a good site which can explain such an experiment:
http://blog.neuroelectrics.com/blog/bid/323640/Quick-Tips-for-P300-Detection I hope the NeuroSky device is not too simple to deliver such an P300 signal, otherwise there are also sample datas which I could test on. best regards, Hans Czylok 2014/1/10 Matthew Taylor <[email protected]> > Maybe something simpler and more reproducible to attempt first (and > bear with me, because I know nothing about EEG) would be to stimulate > the brain with some external sensory input that might produce > recognizable patterns in the EEG output.
