Results based on offline data have a gray background and binary classification accuracy is given in classwised balanced accuracy. Each subject spelled the same two sentences: a short (18 char) sentencea and a long (36 char) sentenceb. Spelling performance is quantified by the time (min), required to spell the complete sentence. Individual differences arise due to false selections. For participants VPnv, VPoc, and VPoe, the second sentence was canceled or not even started. One spelling runx was stopped after the 45th trial.
