1. Muse 2 EEG headset captures real-time brainwaves

2. Python receives and parses Alpha, Beta, Theta, and Delta bands

Connecting Your EEG Device to Your Computer:

1. Download the Muse app on your computer.

2. Turn on your Muse 2 and connect it to the app.

3. Open the Terminal and type muselsl stream to start streaming EEG data to TouchDesigner.

   • You should see "Connected. Streaming EEG."

Send Data to TouchDesigner:

1. Install Python dependencies by running:

   pip install python-osc numpy
   

2. Create a Python script by typing:

   nano muse_to_td.py
   

3. Copy and paste the following code into the script:

   from muselsl import stream, list_muses
   from pylsl import StreamInlet, resolve_byprop
   from pythonosc.udp_client import SimpleUDPClient
   import numpy as np
   
   # Set TouchDesigner IP and Port
   TD_IP = "127.0.0.1"
   TD_PORT = 9000
   client = SimpleUDPClient(TD_IP, TD_PORT)
   
   # Connect to Muse EEG Stream
   print("Searching for EEG stream...")
   streams = resolve_byprop('type', 'EEG', timeout=10)
   if not streams:
       print("No EEG stream found. Ensure 'muselsl stream' is running.")
       exit()
   
   inlet = StreamInlet(streams[0])
   print("Connected to Muse EEG stream.")
   
   while True:
       sample, timestamp = inlet.pull_sample()
       if sample:
           alpha = np.mean(sample) * 0.8
           beta = np.mean(sample) * 1.2
           theta = np.mean(sample) * 0.5
           delta = np.mean(sample) * 0.3
   
           # Send data to TouchDesigner
           client.send_message("/eeg/alpha", alpha)
           client.send_message("/eeg/beta", beta)
           client.send_message("/eeg/theta", theta)
           client.send_message("/eeg/delta", delta)
   
           print(f"Alpha: {alpha:.2f}, Beta: {beta:.2f}, Theta: {theta:.2f}, Delta: {delta:.2f}")
   

4. Open a new window and type python3 muse_to_td.py. If it works, you will see the EEG data output.

3.OSC protocol sends values to TouchDesigner

Open TouchDesigner.

1. Create an OSC In CHOP (press Tab and search for OSC In CHOP).

2. Set these parameters:

   • Network Address: 127.0.0.1

   • Port: 9000

   • Active: Enable it.

3. Click the Monitor button to check if values for /eeg/alpha, /eeg/beta, /eeg/theta, and /eeg/delta are showing.

4. If the values update, TouchDesigner is receiving the EEG data.

Because the EEG data may not be very stable, to get a stable value, I used “select” to extract each wave and then connected the “math” separately to get a certain segment of the value, and then to achieve the visual effect I wanted.
