Figure 6From: The cost of space independence in P300-BCI spellersLetter detection accuracy (left) and ITR (right) in RSVP and Matrix modes. Figure shows mean and standard error of 50:50 train-test letter detection accuracies and ITRs as a function of the number of stimulus repetitions. These were calculated by including features within either 0-800 ms, 0-300 ms, or 300-600 ms of each epoch.Back to article page
