Enhancement of SSVEP-based BCI system via SSAEP during Eye Fatigue Period
نویسندگان
چکیده
This paper proposes the auditory evoked potential (SSAEP) stimulation technique as well as its detection algorithm to replace the steady state visual evoked potential (SSVEP)-based brain-computer interface (BCI) system during the visual fatigue period. Optimal speaker position for two commands SSAEP-based BCI system and the possible electrode positions are investigated. With the proposed system, 85% accuracy for two commands can be achieved at T3-T5 and T4-T6 electrode positions by using only one speaker. Besides the replacement, SSAEP-based BCI system can also increase more commands when using together with the SSVEP system.
