Basics of EEG-based Brain-Computer Interfaces

You know what BCIs are capable of now: controlling robots, cursors, keyboards, video games. But, how? What do you have to think? What exactly is the brain-computer interface system attempting to detect from the brain? How can I get involved!?
In this event, current brain-controlled wheelchair project lead Adam Del Rosso will cover the basics of building a non-invasive EEG-based BCI system. An overview of the many disciplines that contribute to the neurotech field will be provided, including neuroscience, signal processing, and machine learning. Then, Adam will provide a status of work within the brain-controlled wheelchair team and demonstrate the current capabilities of their low-cost BCI system featuring OpenBCI technology.
While this event is targeted towards current and prospective members of the Neurotechnology Exploration Team (NXT) student club at RIT and U of R, all are welcome to attend!

As an "EEG-curious" person with affective computing concepts I'd like to research, and with a little bit bit of money, and with a little bit of programming experience, I found this very informative and a very good, information-dense presentation. Thank you very much for publishing it. I'm surprised the "viewer participation" is so low. Is EEG/BCI the WorldWideWeb (circa 1994) of human-computer interaction?

Thanks for this introduction. We are a plurality whose interest in BCI is to create a new communication channel for our internal muses who do not have the ability to use our physical voice. In doing so we hope to dispel the myths surrounding those of us with multiple personalities. Proving our existence would probably be as dramatic as finding life on Mars. And it would help so many people who are being told that they are crazy to finally be able to show that they are not.

Very interesting presentation! I am 5 years post stroke and have limited use of the left side. My question is are you able to compare the eeg from thought movement of the affected side to the the pattern of the unaffected side? Do, if extend my right wrist, is the pattern exactly the same or pretty close? Could we “copy and paste” the brainwave?

[@dezmar7144]

I am enrolling in a clinical trial, for stroke rehabilitation of the lower limb. They will be using BCI and FES. The FES is activated when you think about the movement of the lower limb. The hope is that the brain will eventually take over the task. By performing the task with the unaffected leg, can the brainwave be recorded and then if by thinking the movement of the affected leg, would the brainwave be similar?

what about psd supression on individual

I'm confused. You said there isn't much to gain in having a dense field of electrodes. But wouldn't a denser field of electrodes allow for triangulation, improving spatial resolution?
