The element of user training for SSVEP-based BCI

Abstract

The paper investigates the element of training and potential advantages it can offer BCI systems operation using visual stimulation method referred to as Steady-State Visual Evoked Potential (SSVEP). The stimulus is presented in the form of black and white checkerboard displayed by a 12.9” tablet screen. The results of one trained user are compared against twelve untrained counterparts. Only 41.6 % of the untrained users could successfully operate BCI system. The trained user produced signals with amplitude values 2x higher on average compared to the untrained users.
