Bryan, hi. What is your goal at this point? Can you just go ahead with your intention to use OpenViBE and one of Jeremy's tutorials on the speller or motor imagery? You have 8 or 16 channels, so even

I've been on Mac the last few years and switched over to Windows 10.I am trying to follow this tutorial.

BCI systems respond in real time. Look around for the threads on the OpenViBE P300 speller and motor imagery. These are not using source localization but rather training on feature extraction. They ar

See also the OpenViBE P300 speller, which Jeremy setup for OpenBCI,

As something more down to earth, take a look at the P300 speller tutorial threads.

Did you follow the suggestion from @Rceballos98 (August 13 post above)? What happens when you run his tutorial? Please reply in this thread, which is for helping those with P300 speller questions.

I'm unable to acquire signals from openbci to my openvibe p300 speller ?

It is my understanding that the P300 speller tutorial for OBCI might be a little outdated since the new OpenViBE release. I think @jfrey might have a bit more information on that.

@ayushmh , I already merged your question into this existing thread. Can you just be patient and see if someone on this existing speller thread will get back to you? You can also try sending a private

Ayush, I merged your question into this existing thread on the speller. When you post on an existing thread, you get more response because previous posters (such as Jeremy @jfrey ) are email notified.

@knife121 , hi. I merged your question into this existing thread on the P300 Speller, which uses OpenViBE. It is the type of BCI speller that is also found in commercial applications, as from g.tec (I

I merged your question about calling C++ from OpenViBE speller into this existing thread for the speller.

[can OpenViBE P300 speller invoke a C++ helper program?]

All mappings are arbitrary and determined by the experimenter. You can see Jeremy's channel mapping for the OpenViBE P300 speller here,

You can connect any channel to any 10-20 site, it's your choice. You can do a lot of good stuff with just 8 or less channels. See the OpenViBE speller tutorial. Note that without the daisy, you get 25

There is a trend toward "hyperscanning" in BCI, my guess is that OpenBCI could make it way cheaper. I have in mind an example with g.tec and P300 speller: 

program running on the board. Also see the P300 Speller thread with OpenViBE, which works fine with either board.

PS the related previous thread on the P300 Speller,

, where I describe how to setup a "P300 speller", that is to say to write using your brain activity -- sorry, no video, it did not seem pertinent at that time, you'll have to take my word f
