THE BR41N.IO DESIGNERS' HACKATHON

 

BR41N.IO is a brainstorming and collaborative marathon designed to be a learning experience for  developers, technologists, engineers, students, artists, and scientists who cram and build brain-computer interface (BCI) applications together in teams. By putting creative minds from multiple disciplines together for a short period of time, BCI-related applications not readily thought of can be discovered and uncovered.

There are several predefined projects at the BR41N.IO Designers' Hackathon, which the participants can choose to work on. Below, the projects are described in detail including hard- and software specifications as well as the number of possible participants for each project.  The Unicorn Brain Interface and the Unicorn Suite application are mostly used to realize BR41N.IO projects. However, additional software should already be installed on your personal laptop before you come to the hackathon.

Who can participate?

Anyone can participate who has interests in BMI, BCI, robotics, AR, VR, machine learning, computing, sensors, human-machine interface systems, control, signal processing, big data, haptics, rehabilitation, and similar areas. Participants do not have to be a BMI expert to participate on a team! Interdisciplinary teams with a combination of BMI and non-BMI skills are often successful in building solutions and producing working prototypes. 

Can I submit a different project?

Professional teams can also participate to develop applications during the BR41N.IO Designers' Hackathon to demonstrate full potential of some of the sponsored hardware/software. If you are looking for team members, your project will be included among the BR41N.IO projects below where people can apply for it. Submit your project to contact@br41n.io.

What's in there for me?

Be creative, think outside the box. The BR41N.IO Designers' Hackathon is fun and gets you to network and collaborate with other Geeks. The best BR41N.IO projects will be awarded with tech-goodies.

What's the location?

The BR41N.IO Hackathon takes place at University of Duisburg-Essen, Campus Essen in Germany. Find the exact location and the timetable here.

BCI PRINCIPLES FOR BR41N.IO

 

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 BCI usage it is important to calibrate the system on each individual person. This is done within 5 minutes. Afterwards the user can already control an application in real-time. An important aspect of BCI usage is that EEG electrodes are fixed over the corresponding brain regions to allow high quality EEG control. Therefore, we are using 8-16 electrodes that are assembled on the sensorimotor cortex, parietal and occipital regions.
