Abstract

Approximately 900,000 Americans have little to no control over their hands, which causes daily tasks to become difficult and decreases quality of life. Our goal is to help improve quality of life with a brain computer interface that allows subjects to read an electronic book (eBook), using affordable, commercially available components. Concentrating on a blinking square induces SSVEP (steady-state visually evoked potentials) signals in the brain’s occipital lobe at the same frequency as the stimulus. The SSVEP signal is used as a control signal to flip pages of an eBook. EEG signals from the occipital lobe are acquired with the Emotiv EPOC headset while the subject concentrates on two squares blinking at different frequencies. Frequency domain features detect if the subject is concentrating on one of the blinking squares, and the control signal is used to turn eBook pages.
