摘要
We present a Brain-Computer Interface (BCI) game. the MindGame, based oil the P300 event-related potential In the MindGame interface P300 events are translated into movements of a character on a three-dimensional game board A linear feature selection and classification scheme is applied to identify P300 events and calculate gradual feedback features from a scalp electrode array. The classification during the online run of the game is computed oil a single-trial basis without averaging over subtrials We achieve classification rates of O 65 on single-trials during the online operation of the system while providing gradual feedback to the player (C) 2009 Elsevier Ltd All rights reserved.
