According to wikipedia, Electroencephalography (EEG) is the recording of electrical activity along the scalp produced by the firing of neurons within the brain. Basically, for EEG, you are looking for electrical activity of your brain by using electrodes. Brainwaves have very low frequency. There are some good projects for EEG like “Open EEG” or “Emotive”. However, I don’t know how easy and reliable it is.
Also, even a simple eye blinking is interfering with EEG values, for my project, I will be tracking people who are moving. So, there will a lot of inference.
I was talking with another ITP student (Neil Hickey), he worked on EEG before for his undergrad. I mentioned him that I will be using galvanic skin response with EEG. He mentioned that, galvanic skin response (GSR) would interfere with EEG also.
As a result, I will not be using EEG for my thesis, because my audience will be moving and I will be using GSR which are interfering with EEG.
Here are some images from my prototype that I made earlier..
