Introduction (you’re past that, thankfully)Table of Contents ( you are here)The OpenBCI is a device that lets (mostly) ordinary artists, tinkerers, or neuroscience researchers measure the electrical activity of their muscles, heart, and brain. The OpenBCI bridges the gap between three previous categories of brain-computer interfaces: Consumer devices, such as the Emotiv, NeuroSky, and Muse headsets, homebrew designs, such ...
Download the latest version of the software for your operating system from the OpenBCI Downloads Page. Follow the installation instructions on the OpenBCI Docs Pagefor your operating system. I had trouble with bugs in the official Linux software, and it took me a while to get it working. If the official instructions don’t work for you either, try t...
Plug the bluetooth dongle that came with your OpenBCI into a USB port, making sure the dongle’s switch is at the position lablled “GPIO6” (slid toward the computer), as opposed to the “RESET” posti...With the battery pack plugged in, slide the switch on the OpenBCI to “PC”. It should also have a blue indicator light when it’s turned on. (Note: I’d read that the blue indicator is supposed to fla...Launch the OpenBCI GUI with root privileges again, with the terminal command cd ~/application.linux64 && sudo bash OpenBCI_GUISelect “LIVE (From OpenBCI)” from the list of data sources.For the initial test of an EEG (Electroencephalograph, a device that measures electrical activity in the brain) it’s good to use a strong signal that you’ll recognize if everything’s working. Measuring EKG activity — electrical activity of the heart — is a popular first test, because it has a recognizable pattern and a strong signal. Electrical act...
Follow the same stepsyou used to test the connection at the beginning to start the data stream — plug in the dongle, turn on the OpenBCI, launch the GUI as root, select the correct serial port and settings, and click start system. Before you start the data stream, turn off the unused channels and set the gain for EKG. On the far left of the screen ...
It takes few seconds for the signal to settle out to anything meaningful. Adjust the electrodes as necessary. Although I’m not experienced with EKG, from what I could tell my signal was quite good for such a basic setup. After the initial run, I put a Micro SD card into the OpenBCI and restarted the GUI, this time setting it to log data to make sur...
When you’re done, clean the conductive paste from the electrodes to prevent them from corroding: Dunk the electrodes you used in near-boiling water a few times, making sure that the paste is all dissolved, then dry them and put them away. Leaving them soaking isn’t recommended, as the dissolved paste can damage the connection between the lead and e...
Hopefully this will help you take your initial OpenBCI recordings and minimize time spent dealing with technical issues. Next up: brainwaves! I’ll probably start with the easiest type to measure, alpha (7.5–12.5 Hz) activity over the occipital lobe (the back of the head), and publish my results, or perhaps a tutorial, here.

Feb 14, 2022 · Key steps to design a BCI for emotion recognition. More concretely, to design and deploy a BCI, several key steps have to be followed. Paradigm definition and signals recording. What do I want to model or estimate? What is the aim of my application? Do I want to control mechanical hands/feet? Assess vigilance during driving tasks? Predict diseases?
