Great, keep up the good work. I'm only mentioning MindAffect because it is the most impressive BCI speller I've ever seen. You may be just fine with the OpenViBE P300 speller. As you mention you've al

P300 signal is so noisy, signal averaging is REQUIRED to bring the signal out of the noise. Please don't write off MindAffect as 'impossible' or unworkable, unless you have actually tried it and confi

But, in the P300 speller, the target letter flashes 15 times (it is possible to get averages) and if the persons looks at another letter for a moment it is not a big problem because doesn't start the

I guess I don't understand what P300 speller you are using. Don't all spellers have some sort of 'keyboard' that you look at? (The OpenViBE speller has this.) Typically the rows and columns of this le

PLEASE try the MindAffect cVEP based speller instead of the very old and unmaintained OpenViBE P300 speller. I am almost certain you will find it faster and more accurate.

The following is not SSVEP, but it is much better, called cVEP (code based). Many times easier and faster to operate (for the subject) than SSVEP. An SSVEP speller would require a multi-layer choice t

I searched this and other forums in order to find some open-source ssvep keyboard that I could use for creating a working speller with my openBCI setup. Unfortunately, I did not find anything that cou

This is a cVEP (code based Visual Evoked Potentials) speller from Mindaffect. Which is not over-hyped.

I hope you're doing well! Yes, I am using the OpenVIBE speller apps. It is true that the apps are pretty old... However, they do work somewhat with my headset right now -- admittedly not that well. I

Can you clarify if you are running the OpenViBE P300 speller apps? These are very old, no longer supported, and have not been updated for years. Link below shows history of OpenViBE forum posts regard
