| This study focuses on developing a method to determine parameters to control
cursor movement using noninvasive brain signals, or electroencephalogram
(EEG) for brain-computer interface (BCI). There were two conditions applied i.e.
Control condition where subjects relax (resting state); and Task condition where
subjects imagine a movement. During both conditions, EEG signals were
recorded from 19 scalp locations. In Task condition, subjects were asked to
imagine a movement to move the cursor on the screen towards target position.
Fast Fourier Transform (FFT) was used to analyse the recorded EEG signals.
To obtain maximum speed and accuracy, EEG data were divided into various
interval and difference in power values between Task and Control conditions
were calculated. As conclusion, the present study suggests that difference in
delta frequency band between resting and active imagination may be use to
control one dimensional cursor movement and the region that gives optimum
output is at the parietal region. |
