Many signal processing techniques have been utilized in P300-Speller to restore the communication ability of these locked-in people. These techniques are capable of achieving high classification accuracy. However the classification accuracy dramatically decreases for single trial analysis. The reason for that is that the noises existing in the recorded signals are usually removed by averaging several trials. When only a single trial is available, averaging is no longer an option for de-noising. The \u201caveraging\u201d step becomes the bottle neck of P300 response detection which highly limits the processing speed. Researchers are looking for techniques that can accomplish the classification task in a single trial. In this work, a new, effective but simple processing technique for single trial electroencephalography (EEG) classification using variance analysis based method is presented. This method achieved an overall accuracy of 84.8% for single trial P300 response identification. When compared with a single trial stepwise linear discriminant analysis (SWLDA), the authors\u2019 method in terms of overall accuracy is more accurate and the data communication speed is significantly improved.<\/p>","DOI":"10.4018\/jehmc.2012100103","type":"journal-article","created":{"date-parts":[[2012,12,17]],"date-time":"2012-12-17T13:42:27Z","timestamp":1355751747000},"page":"31-41","source":"Crossref","is-referenced-by-count":2,"title":["A New Single Trial P300 Classification Method"],"prefix":"10.4018","volume":"3","author":[{"given":"Kun","family":"Li","sequence":"first","affiliation":[{"name":"Department of Electrical Engineering, University of South Florida, Tampa, FL, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ravi","family":"Sankar","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, University of South Florida, Tampa, FL, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ke","family":"Cao","sequence":"additional","affiliation":[{"name":"H.
