— This paper describes an optimization strategy for steady state visual evoked potential (SSVEP)-based brain-computer interface (BCI), especially in a spelling program application. In this application, there are at least three components for implementing a complete BCI application: stimulator, signal processing, and application (spelling program). Ideally,(More)
INTRODUCTION Brain – computer interface (BCI) systems allow people to send information without moving [1]. Some BCIs rely on the Steady State Visual Evoked Potential (SSVEP), a type of EEG activity that occurs when subjects focus attention on a stimulus that oscillates between about 5-40 Hz. Thus, the efficacy of an SSVEP BCI depends on how quickly and(More)
