MOTOR IMAGERY BASED ON WAVELET POWER SPECTRUM FOR A BRAIN COMPUTER INTERFACE

A Brain Computer Interface (BCI) is often used to command devices and clinical applications. In this study a BCI based on wavelet power spectrum using motor imagery is implemented. Four motor tasks were used and the method proposed achieved success rate of 89% and ITR of 11.40 bit/min. The proposed method had statistical significance (p-value 2.0) for sensitivity, specificity,
