Brain-Computer Interface calibration

An EMG-controlled interface for BCI calibration with a gamification mode powered via Brainflow.

This interface has two modes:

An instruction-only interface with no feedback
A gamified interface with EMG feedback

The goal of this project is to provide an interface for subjects performing motor tasks. The gamification mode is intended to provide a more engaging experience for subjects.

Installation

Clone the repository
Install the dependencies with pip install -r requirements.txt

Usage

Run the interface with python main.py.

Scene selection

There are two scenes available:

--mode instructions (default) will display the scene with bare motor task instructions
--mode game will display the scene with the gamified interface

Data source

There are three ways to ingest data:

--input cyton (default) will ingest data directly from OpenBCI Cyton board
--input playback will ingest data from a file recorded with Brainflow.
- By default, the data is streamed from examples/example_1.csv. Use --file <FILENAME> to specify a different file.
--input openbci will ingest data from OpenBCI GUI on 225.1.1.1:6677. The assumption is that the streamed data come from a Cyton board.

Additional options

--fullscreen will display the interface in fullscreen mode. If not provided, the interface will be displayed in a small 800x600 window.
--channel <CHANNEL_NUMBER> will select the channel to use for the EMG feedback. By default, channel 1 is used.
