DiscussionUsing VR with brain waves (self.learnVRdev)

ThejusPU が 投稿

I'm doing my senior year project on seeing how effectively we perceive emotions in VR, using an EEG (an electroencephalogram). Eventually I want to make a horror game that will be able to read signals from the EEG and decide what happens in the game to effectively scare the person. In our lab we have an Emotiv and Open BCI. The other more complex systems are too occupied :P We are also using OpenVibe to read data. Anyone have any advice on which VR System I should get to be able to have an interconnected system that will work in real time with the brain waves.

Very cool! I think about doing this all the time, but don't have access to the hardware. Let me try to help as best I can. Also, you might want to talk to a behavioral psychology team who posted something similar recently, except having to do with eye tracking instead of EEG results.

I wrote this guide to hardware and software platforms for developing VR experiences. I'm not familiar with any game engines like Unity or Unreal3D that features built-in plugins for EEG results. You'd probably have to find a plugin or open source platform that you can use to push the data from OpenVibe/your EEG hardware to an in-engine object. This doesn't seem like a particularly difficult task, and I'm sure other researchers have methods for achieving it, although I don't have any examples handy.

The big question is, what sort of capability do you need in the VR experience? If you want a fully interactive world that responds to a player's EEG readings and such, that is quite a task! It might be easier to just make a 360 video and then get readings of the subject's responses to stimuli of vision/presence, although this doesn't have quite the utility of a VR experience which truly responds to subject feedback.
