Online spelling using AMUSE Auditory MUlticlass Spatial ERP BCI
Although the P300 spelling grid has been modestly successful even for patients, the visual ﬂashes that are needed are not accessible for those with vision deterioration. For these potential users, tactile or auditory stimulation are the modalities of choice, but their implementations are mostly binary in nature. In [1,2] we presented the ofﬂine results for a new auditory multi-class paradigm to overcome some of these difﬁculties. Here we present the results from an online trial with 21 healthy subjects.
