Abstract

MUCH PROGRESS HAS RECENTLY BEEN MADE IN BRAIN COMPUTER INTERFACE. DIFFERENT APPROACHES HAVE BEEN INTRODUCED TO REALIZE THIS INTERFACE BETWEEN COMPUTER AND PATIENT. WE CAN SEE SUCH INSTRUMENTS AVAILABLE IN FOREIGN TRADING CENTERS WHICH ARE USED BY A FEW PATIENTS BECAUSE OF THEIR HIGH EXPENSE. CONVENTIONAL SIGNALS USED FOR PROCESSING DURING THE BRAIN COMPUTER INTERFACE ARE ERS/ERD, SIGNALS, MU RHYTHM AND ERP. AMONG THESE SIGNALS, ERP HAS BEEN PRECEDE TO ACHIEVE THIS INTERFACE, IN THIS PAPER THE PROCEDURE IS STARTED BY VISUAL STIMULATION USING A TYPICAL QUADRATIC CROSS, RECORDING AND PROCESSING THE EEG SIGNAL FROM THE PZ, CZ, FZ CHANNELS SIMULTANEOUSLY WITH EOG CHANNELS FOR ARTIFACT OMITTING. IN THIS CASE, AN ERP SIGNAL OCCURS WITH THE PATIENT’S CHOICE WHICH IS RECOGNIZED BY THE PROCESS INTRODUCED IN THIS METHOD. THE ADVANTAGES OF THIS METHOD ARE HIGH PROCESSING SPEED AND THAT THE PATIENT NEED NOT TO BE TRAINED, BUT MANY TRAINING SESSIONS ARE (A FEW MONTHS) INCREDIBLE IN OTHER METHODS. SEVERAL METHODS HAVE BEEN INTRODUCED FOR RECOGNIZING THE PROCESSING METHOD MENTIONED HERE, IS A COMBINATION OF THE “PEAK-PICKING” METHOD, CORRELATION ,”MAXIMUM LIKELIHOOD METHOD FOR ESTIMATING THE AMPLITUDE AND LATENCIES OF EVOKED POTENTIALS” AND FINALLY “THE METHOD OF ERP COGNITIVE ELEMENTS RECOGNITION IN EEG USING WAVELET COEFFICIENTS”. THIS METHOD WAS TESTED ON TWO PERSONS (25 AND 26 YEARS OLD MAN). THE EFFICIENCY WAS 78% IN TARGET STIMULATION AND 85% IN NO TARGET STIMULATION, SIMILARLY THESE PERCENTS WERE 76% AND 83% FOR THE OTHER. THESE EFFICIENCIES ARE SOMEHOW NOTICEABLE THAT IS HOPED TO BE IMPROVED.
