Brain Computer Interfaces (BCI) is a system that allows you to control machines using your brain activity directly, rather than through intermediary interfaces like a mouse, keyboard, touchscreen or voice.

EmotivBCI is a desktop application for Mac and Windows that allows you to view and train the EMOTIV data streams used for BCI. These data streams are the following:
