Re: EEG digital board questions

Hello Yang,

I don't know enough to address your hardware questions regarding the 
OpenEEG.

Regarding sensing emotions with EEG: do you have an algorithm in mind to 
do this? Emotion detection, or "affective BCI", is an area in which 
there has been a lot of research but there are not many well-accepted 
general purpose algorithms.

If you're looking for an overview, this thread on NeuroBB has some good 
starting points:

Good luck with your project!
