Unicorn Hybrid Black
The Unicorn Hybrid Black 8-channel EEG is a low-cost head-mounted and wireless EEG system that is developed and distributed by Gtec. Besides 8 channels of EEG, it provides 3 accelerometer channels, 3 gyroscope channel, the battery status and a sample counter.
The Unicorn is available in a “Black” version, including head-mounted enclosure, and in a “Naked” PCB-only version.
Interface with MATLAB and FieldTrip
This MATLAB implementation mainly serves the purpose to test and demonstrate whether the Bluetooth protocol can directly be used on other (non-Windows) computers and to decipher the data stream. This implementation is inefficient and unstable, hence we recommend not to use this for serious research.
The ft_realtime_unicornproxy function implements a native interface between the Bluetooth-connected Unicorn system and the FieldTrip buffer.
Windows and LSL
The Unicorn system comes with a Windows-only software suite, which uncludes the UnicornLSL application that streams data directly to LabStreamingLayer (LSL). Since LSL is compatible with MATLAB, Python and C/C++, you can use this. This is a robust solution, but requires a Windows data acquisition computer.
BrainFlow lists the Unicorn as one of the supported systems. It seems that it makes use of Python bindings to the proprietary dynamically linked library (dll) which is available for Windows and Linux (on Intel and Raspberry Pi).
