document: Design and implementation of a brain-computer interface with high transfer rates This paper presents a brain-computer interface -LRB- BCI -RRB- that can help users to input phone numbers . The system is based on the steady-state visual evoked potential -LRB- SSVEP -RRB- . Twelve buttons illuminated at different rates were displayed on a computer monitor . The buttons constituted a virtual telephone keypad , representing the ten digits 0-9 , BACKSPACE , and ENTER . Users could input phone number by gazing at these buttons . The frequency-coded SSVEP was used to judge which button the user desired . Eight of the thirteen subjects succeeded in ringing the mobile phone using the system . The average transfer rate over all subjects was 27.15 bits/min . The attractive features of the system are noninvasive signal recording , little training required for use , and high information transfer rate . Approaches to improve the performance of the system are discussed
