HALF-FIELD SSVEP BASED BCI SYSTEM AND MOTION METHOD THEREOF

摘要

Disclosed are a BCI based SSVEP system and a method for operating the same. The BCI based SSVEP system comprises an EEG detection electrode unit which is attached to an occipital lobe of a user to measure a brainwave signal; a target staring unit in which a plurality of eyeline staring targets consisting of texts and numbers are arranged and which includes a plurality of visual stimulators that are arranged between two of the eyeline staring targets and are lighted on/off by different frequencies; and a processing unit which classifies and processes the brainwave signal outputted from the EEG detection electrode unit when the user stares each of the targets included in the target staring unit.
