Brain Computer Interface (BCI) - Hello World Code!¶

BCI connects the brain to computers or devices.

There is Different types of BCI devices exist, such as EEG or fNIRS etc.

This is an EEG BCI hello world code in Python using OpenBCI library.

BCI Applications¶

• controlling a robotic arm,
• playing a video game
• typing a message

BCI is a fascinating and promising field of research that can have many benefits for humanity

In [ ]:

# Import the OpenBCI library
import openbci

# Define a callback function to process the EEG data
def process_data(sample):
    # Get the EEG channel values
    eeg_channels = sample.channels_data

    # Get the blink value (1 if blink, 0 if not)
    blink = sample.aux_data[0]

    # Print the EEG channel values
    print("EEG channels:", eeg_channels)

    # Print "Hello World!" if blink
    if blink == 1:
        print("Hello World!")

# Create an OpenBCI object
board = openbci.OpenBCIBoard(port='COM3', baud=115200)

# Start streaming the EEG data and call the callback function
board.start_streaming(process_data)
