The Unicorn Brain Interface is a high-quality wireless EEG-headset for brain-computer interface (BCI) applications to perfectly acquire brain waves. The Unicorn Brain Interface allows developers, artists and makers to acquire and process brain signals, ranging from simple display of the signals, to design and control attached devices or interact e.g. with artistic installations, toys, computer programs or applications. Unicorn Brain Interface acquires EEG from eight Unicorn Hybrid EEG Electrodes and comes with the Unicorn Suite, the main software application for the Unicorn Brain Interface. The data is sampled with 24 Bit and sampled with 250 Hz per channel.
The unique Unicorn hybrid EEG electrodes allow users to record dry or with gel which enables the usage for many different applications. The electrodes are placed per default on the
- sensorimotor cortex to realize motor imagery based BCIs,
- over the central, parietal and occipital areas for P300 paradigms and
- over the parietal regions for steady-state visual evoked potential (SSVEP) and code-based VEP paradigms.
Reference and ground electrodes are fixed on the mastoids for perfect noise reduction. The Unicorn Brain Interface is extremely lightweight to reduce movement artifacts, fits perfectly to different head shapes and keeps the device in position to guarantee the solid contact of the electrode to the scalp which is key for high quality recordings. The battery lasts for 2 hours and status LEDs in the Unicorn allow the user to see the operational status of the device.
