Re: SSVEP-Based BCI
Thanks Boulay, yeah I have read a lot about the frequencies I can make within the range that my monitor's refresh rate allows me. Now my only problem is how to generate these frequencies. My virtual world is in VRealbuilder and I have to generate the stimulus in it, since I can't have another progra...

Re: SSVEP-Based BCI
That's one of my big concerns, I want to have some lamps to flash in the VR world, I don't have time to use LEDs and I'm not professional in programming them. I need to either : . Put four flashing lamps around the virtual world page which have the camera's coordinates and move with it while navigat...

Re: SSVEP-Based BCI
I tried to find a way not to use BCI2000 and just use Emotiv and MATLAB,
but it seems to be harder than using BCI2000
Do you know anyone who has worked on this?
I mean connecting Emotiv directly to MATLAB.
Thank you.

Re: SSVEP-Based BCI
My preferance is to do all this asynchronously, so it's going to b harder..
How can I find that MATLAB-based Emotiv library?
And also, I need to give the user a feedback, right? Is it better to be just a sound or I need to do something visually too?
Thanks a lot.

Re: SSVEP-Based BCI
Hi Boulay, Thanks for the response. Yes, VRealmBuilder is MATLAB-based. Can you explain what you mean by doing the signal acquisition from the EPOC in MATLAB? I can read the data recorded by Emotiv which is connected to BCI2000, in MATLAB, by converting .dat files to .mat You mean there's no nead fo...

SSVEP-Based BCI
Hi all, I am working on a BCI system in which the user navigates in a virtual world using four commands with four specific frequencies to evoke the SSVEP. I'm recording the EEG using Emotiv EPOC and my virtual world is built in the VrealmBuilder and I have to do the signal processing in MATLAB. I ne...
