  • Using the basic P300 example scenarios of OpenViBE

    NB: Document ONLY concerns OpenViBE 1.1.0 and earlier In OpenViBE 1.1.0 and earlier, the P300 scenarios bundled with OpenViBE in bci-examples/p300-speller* suffer from a glitch that makes them non-precise in some conditions. In order to make them work well you should follow some specific practices. Where is the problem This paragraph explains where is the issue with the current implementation. If you want to simply make P300 work you can saf... Continue reading
