description |
A Brain-Computer Interface (BCI) system that is being developed at the
University of Malaya for the control of a prosthetic hand consists of a computer, a BCI
box and a prosthetic hand. Electroencephalogram (EEG) signals are acquired using two
or four electrodes placed on the scalp of a subject. In the BCI box, the EEG signals are
amplified and filtered. The filtered signals are digitized and sent to a computer. Signal
processing, feature extraction and classification are carried out in the computer. The
classification results are sent to the controller to operate the prosthetic hand.
The present thesis describes my contribution to the development of the digitizer
and the communication system between the digitizer and the computer and other
devices. The filtered EEG signals are digitized at a sampling rate of 256 Hz and with a
resolution of 16 bits. The digitized data are sent to a computer through a universal serial
bus (USB) wire or a Bluetooth unit. A main control program in the computer
continuously reads the digitized data and transfers the data to a sub-program for signal
processing, feature extraction and classification. The output decision of the classifier is
sent to the controller to operate the prosthetic hand or to switch on one of four light
emitting diode (LED) lights that represent devices. |
