Help, i don't get how to use BCI

[kisioka]

Hi guys!
I'm attending the last year of high school(it's a technical institute with specialization in informatic). I'll have the final exam, and i wanted to talk about BCI. Now, 50 days(more o less) before, i got that the argument is more and more and more difficult of what i would have thought(even interesting).
In my paper i talked about the acquisition, the amplification and filtering, but i didn't made a system acquisition (no disponibility of electrodes) so i wanted to make something more particular about the programmation. I discovered BCI2000, IT'S FANTASTIC!, but i don't get how to use it .
In my mind i had planned to do something like:
-Analysis of a signal pre registered
-Application of the elaborated signal in a program written in c++
Can someone give me an' hint or, if it's possible, an exampe?

Hi,

Try the mu-rhythm tutorial link near the top-right of the page linked here.
Please post here if any of the tutorial steps do not work for you.

Good luck,
Chad

The program of the cursor task(just the black square where the ball moves around) is just a software that receive data form outside and associates them to the position of the ball?

That's close. The data controls the speed, not the position, of the ball.

A BCI comprises 3 parts: (1) brain signal acquisition and storage, (2) signal processing to convert brain signals to control signals, (3) an application that uses the control signals to control some stimulus or feedback.

You are asking just about one specific implementation of part 3. The same control signals can be used to control a robotic arm, a videogame, a lightswitch, or just about anything with 1,2, or 3 degrees of freedom. Users can use the BCI to communicate or using the BCI can act as a sort of training to improve how the brain functions.

I also encourage you to check out the P300 speller tutorial (linked at the same page as the mu rhythm tutorial). It uses entirely different signal processing and application but it is probably more effective for communication than is the mu rhythm + cursor task.
