BCI PRINCIPLES
Brain-computer interfaces are realized by 4 different principles:
slow waves
steady-state visual evoked potentials (SSVEP)
motor imagery (MI)
evoked potentials (EP)
In the BR41N.IO Hackathon Series, motor imagery and EP based systems
are mostly used to control the applications:
In the case of the motor imagery application, participants have to imagine e.g. left or right hand movement to produce an event-related desynchronization over the sensorimotor cortex. This is basically an amplitude change of the alpha and beta regions of the EEG.
In the case of EPs, the BCI system is showing different flashing icons and the user has to attend to the icon he wants to select. When the icon flashes on the computer screen, than a P300 wave is produced in the brain and the BCI system is able to detect it.
FOR UNICORN HYBRID BLACK OWNERS
Do you have a Unicorn Hybrid Black, a Unicorn Naked BCI or the Unicorn Education Kit at your university or at your lab? Great! Let's put together 40 students in teams of 5 students and let them participate and compete against other international students at this virtual BR41N.IO Hackathon.
As Unicorn Education Kit owner, you'll qualify as a Hosting Institution for this BR41N.IO Hackathon. This means, you'll get a speaking slot during the hackathon and raise awareness for your university.
Unicorn Education Kit is perfectly designed for professors who teach brain-computer interfaces, biomedical engineering or signal processing.
It comes with 8 Unicorn Hybrid Black devices including full access to the Unicorn Suite software.
Unicorn Hybrid Black is a wearable 8-channel EEG device that measures high-quality EEG signals from your brain.
It is perfectly suitable for creating your own brain-computer interface or neuroscience applications.
