EEG2OSC was created for Rafał Zapała's Sensorium project. It was used to pass data from Emotiv EPOC EEG Headset to Max/MSP.
The code is available as open source: szymonkaliski/EEG2OSC/
For EEG data we used Emotiv EPOC and written a data transceiver which outputs OSC messages - it's open source and available for free: szymonkaliski/EEG2OSC.
