To solve the problems that the conventional brain-computer interfaces (BCIs) transfer the mental intents into the control commands with a low judgment accuracy and unsatisfied information transfer rate (ITR)

a novel hybrid BCI called the P300-SSVEP-Speller was developed on the basis of the P300-Speller to combine SSVEP blocking (SSVEPB) features with P300 potentials.The offline usage of twelve subjects was investigated in the study.Results show that the elicited SSVEPB has little influence on the emergence of the P300 potentials in the degree of temporal signals.In addition

from the view of character recognition

the novel P300-SSVEP-Speller system has a better performance than the conventional P300-Speller on the judgment accuracy and ITR.
