TY - JOUR T1 - Should the parameters of a BCI translation algorithm be continually adapted?. JF - Journal of neuroscience methods Y1 - 2011 A1 - Dennis J. McFarland A1 - Sarnacki, William A. A1 - Jonathan Wolpaw KW - adaptation KW - brain-computer interface KW - EEG AB - People with or without motor disabilities can learn to control sensorimotor rhythms (SMRs) recorded from the scalp to move a computer cursor in one or more dimensions or can use the P300 event-related potential as a control signal to make discrete selections. Data collected from individuals using an SMR-based or P300-based BCI were evaluated offline to estimate the impact on performance of continually adapting the parameters of the translation algorithm during BCI operation. The performance of the SMR-based BCI was enhanced by adaptive updating of the feature weights or adaptive normalization of the features. In contrast, P300 performance did not benefit from either of these procedures. VL - 199 UR - http://www.ncbi.nlm.nih.gov/pubmed/21571004 ER -
