OpenViBE P300 Benchmarks
Hi everyone,
I've been trying the OpenVibe implementations of the P300 with OpenBCI. I know there are some old posts on P300 on this forum, but it's been quite a while and the old techniques do not necessarily translate over to the most recent version of OpenVibe. In the online evaluations, I usually get less than 50% accuracy (3 or 4 letters guessed correctly out of 10). This is despite an 80% accuracy in cross validation tests. I've run the scenarios with very little modifications, so I might need to make some more tweaks. Has anyone else tried the P300 experiments? If so, please share your results on this thread!

Winson, hi.
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 regarding speller.

Hi William!
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 know Jeremy did a tutorial many years ago with excellent accuracy. In any case, I'll look into the links you posted a bit more. Thanks!
