This paper demonstrates a high performance brain-computer interface (BCI) that allows users to dial phone numbers. The system is based on Canonical Correlation Analysis (CCA) and Steady-State Visual Evoked Potential (SSVEP). Through six frequency bands (9Hz, 10Hz, 11Hz, 12Hz, 13 Hz, 14Hz) displayed on the screen, subjects can choose a phone number by gazing at the display interface. This proposed EEG system has been implemented in Field-Programmable Gate Arrays (FPGA), and shows high accuracy, high integration density, and low cost. These features are meaningful for implementing a real-time SSVEP-based BCI.
