a couple of months back I bought myself Emotiv Epoc EEG headset. As I thought to save some money I didn’t purchase researcher license. Without the researcher license I wasn’t able to use Epoc’s API to get access to the raw data each electrode conveys. Without this access, I was able to play a little with free apps provided in Emotiv Store, but very quickly got bored.
Luckily later on I found out someone had hacked Epoc’s drivers and decrypted the data encryption, which meant it was now possible to see the raw sensor data. One of those hack implementations was done in java and because it had a very simple user interface and no option to save EEG data, I decided to create proper GUI for my research purposes on top of that.
