Takes EEG data coming in from an OpenEEG device, splits it into the different brainwaves and uses them to change an almost real-time OpenGL ES visualization. The purpose is to teach basic meditation by keeping the visualizations as static as possible.
It currently works on two platforms: X Windows (linux) and Raspberry Pi (tested with Raspbian)
Linux (X Windows)
To run on X11, the following libraries are required to be installed in /usr/include: X11, GLESv2, EGL, rfftw, fftw, Math and pthread.
These commands should take care of all setup on a Debian-based system, you may need to adapt for other systems:
sudo apt-get install git cmake libglm-dev sudo apt-get install libx11-dev sudo apt-get install libgles2-mesa-dev make setup_nsd # Fails? Install neuroserver manually (https://github.com/BCI-AR/NeuroServer) make setup_fftw2 # Fails? Install FFTW 2.1.5 manually (http://www.fftw.org/download.html) make meditrainer_x11 # Fails? Please contact the author!
If all of the above went correctly, these executable files should exist:
nsd modeegdriver meditrainer
./nsd # Starts neuroserver TCP server for EEG data sudo ./modeegdriver -d /dev/ttyUSB0 # Starts a driver to stream EEG data to the nsd. ttyUSB0 should point to the OpenEEG drive. ./meditrainer
At this point you should see red lines on a black screen. This is calibration mode.
Press the space bar or the 'a' key to move on to the different visualizations.
