From Wikipedia, the free encyclopedia
OpenBCI 32bit Board

OpenBCIis anopen-sourcebrain–computer interfaceplatform,[1]created by Joel Murphy andConor Russomanno,after a successful Kickstarter campaign in late 2013.

OpenBCI boards can be used to measure and record electrical activity produced by the brain (EEG), muscles (EMG), and heart (EKG), and is compatible with standard EEG electrodes. The OpenBCI boards can be used with the open source OpenBCI GUI, or they can be integrated with other open-source EEG signal processing tools.

Hardware

[edit]

The OpenBCI 32-bit board uses the ADS1299, anICdeveloped byTexas Instrumentsfor biopotential measurements.[2]The OpenBCI uses amicrocontrollerfor on-board processing — the 8bit version (now deprecated) uses anArduino-compatible ATmega328P IC, while the 32bit board uses aPICmicrocontroller — and can write the EEG data to an SD card, or transmit it to software on a computer over abluetoothlink.

In 2015, OpenBCI announced the Ganglion board with a 2ndKickstartercampaign. It has 4 input channels for measuring EEG, EMG, and EKG, and is also Bluetooth enabled. Initially it was offered on Kickstarter at $99,[3]before later being listed at $249.99,[4]and subsequently increasing in price to $499.00.[5]

Software

OpenBCI has released an open-source application for use with the OpenBCI, written withProcessing.Display and processing software written inNodeJSandPythonare also available.

3D Printed Headset

Design files for a3D printedheadset for pre-production OpenBCI boards have been released onGitHub.The headset, known as the Ultracortex, holds the electrodes in place, and makes it easy to configure their placement using the10–20 System.A headset design files are available for download from OpenBCI's GitHub account, or the headset can be purchased from the OpenBCI online store. The headsets are manufactured and produced by Voodoo Manufacturing.

Applications

[edit]

The OpenBCI has been used to control a HexBug robot usingSSVEPs(Steady State VisuallyEvoked Potentials).[6]Locked ingraffiti artistTempt Onehas used the OpenBCI and the low-costEyewritereye-tracking system to continue to draw after being diagnosed with the degenerative nerve disorderALS.[7]
