Assessment of steady-state visual evoked potential for brain computer communication

Abstract

This paper describes the investigation of the steady-state visual evoked potential (SSVEP) response elicited by a flickering visual stimulus. Preliminary results from five subjects have shown that SSVEP have certain characteristics including good signal to noise ratio (SNR), minimal user training and number of electrodes, despite constraints such as the need for a visual stimulating apparatus and possible induced of visual fatigue. Based on these promising results, SSVEP can be used as a tool for controlling signal for future brain computer interface (BCI) application.
