Implementation of an Intelligent Telephone Dialing System Based on the Control of Steady-State Visual Evoked Potentials

Abstract

With the development of brain-computer interface (BCI) technology, researchers are now attempting to put current BCI techniques into practical applications. This paper proposes an intelligent telephone dialing system controlled by a steady-state visual evoked potential (SSVEP) based BCI. This dialing system consists of four parts: a visual stimulator, EEG signal acquisition and amplification, PC real-time processing system and an auto telephone dialing module. Seven volunteers participated in an experiment designed to test the performance of the dialing system. The experimental results suggested that all subjects succeeded in the phone dialing with mean accuracy rate of 94.5% and mean bit rate of 33.31 bit/min.
