Fear detection

Hello, i am building an app, a VR horror game in unity more specifically. I want the AI of the game to adapt and become harder the more the player fears . I wanted to ask you if is it possible using the OpenBCI via EEG signals to detect fear levels in real time for the AI to use.

    Yes, but have you considered instead using polygraph type measures of heart rate and skin conductance?

    CodeMaster, hi.

    I would agree with Billh, there are probably easier was to gauge stress level with GSR (skin conductance) and heart measures (pulse rate or HRV).


    Check out the Wild Divine game, which incorporated GSR in the VR simulation.


    But there are papers showing EEG correlates of anxiety.

    I have considered both HRV and GSR before. I thought that maybe EEG would be much more accurate and more efficient. I have practically no idea about EEG. During this week i am doing research on it and trying to figure out how will be possible. Someone advised me that since i have no idea how to  make it work, maybe i should train it via neural networks. However you might have already thought that this means that i am gonna need a lot of data to train it. Any advice and opinion is welcome. Maybe EEG is not the best solution and HRV and GSR is easier and have better results. If so can you recommend me a device or board for GSR since the lab i am working on doesnt have any and we may have to buy one. 
    Thank for your time and answers

    "I thought that maybe EEG would be much more accurate and more efficient." Actually it's the other way around. 

    I don't have experience with specific GSR devices, but there are some on the market that connect for example with usb. Other search results will show you ways to achieve GSR with simple Arduino setups (also connected via usb).
