Open-source projects[edit]

Emokit is an open-source Python library for reading out sensor data from the EPOC (Emotiv Systems) by Cody Brocious. It was built by reverse-engineering the encrypted protocol.[34] Emokit has been deprecated in favour of emokit.[35]

In 2011 Make Magazine published an article on hacking NeuroSky headsets. In 2012 Hack a Day published an article on modifying NeuroSky headsets for sleep and dream research.

Open-source Matlab toolboxes such as EEGLAB, Fieldtrip, and the Neurophysiological Biomarker Toolbox (NBT) can be used to process data from the electroencephalography. The Fieldtrip toolbox also offers a real-time plugin.[36]

OpenVibe is a LGPL software platform (C++) to design, test and use BCI.[37] The software comes with an acquisition server that is currently compatible with many EEG device including Neurosky Mindset, Emotiv EPOC (Research Edition or above) and OpenEEG. The software is developed at INRIA.

Several open-source computer programs are also available from EPFL's CNBI project.[38][39]

The openEEG project [2] has developed several open hardware EEG devices while the openBCI project [3] plans to release an open hardware device in 2014.

Technology[edit]

The iFocusBand is the only stand-alone BCI so it's well suited to the non technical community. All of the devices listed use electroencephalography except the Neural Impulse Actuator which only uses electromyography. Some use both electroencephalography and electromyography, such as the BrainBand MindWave, EPOC, and MindSet.
