From BCI

Open BCI: from lab to bedside

For more than a decade brain-computer interfaces (BCIs) have been a fashionable topic of several "proof of concept" studies. Time has come to combine the achievements of technology, psychophysics, neuroinformatics and all the relevant sciences into appliances that can help patients with dramatically limited communication possibilities. We believe in open development of software (GPL) and sharing of hardware designs not restricted by patents.

BCI Appliance

This design pioneers a new line of thought about the user-centered design of BCI systems: a simple box with on/off button, minimum necessary software, and user-controlled mode switching, connecting wirelessly to domotic and EEG acquisition devices. World's first solution providing dynamic menus for stable SSVEP stimuli.

Software

OpenBCI system is a very beginning version of a complete platform for brain-computer interfaces. As a signal display we intend to use Svarog -- Signal Viewer, Analyzer and Recorder on GPL. Finally, matching pursuit is a computationally intensive algorithm for adaptive approximation of signals in time-frequency dictionaries. At the moment it may be cosidered more on the research side of BCI, but given a free implementation open to optimizations for particular tasks, online applications are proven doable.

Communication with EEG hardware

Both Svarog and OpenBCI system communicate with EEG hardware via Multiplexer, hence the drivers will be common to both projects. Click here for current status.
