Abstract :
A new approach to realise computer monitor flickers that can be used to elicit steady-state visual evoked potentials (SSVEP) at a flexible frequency is proposed. An SSVEP-based brain-computer interface (BCI) with 16 targets was then implemented using the proposed method. In an online test on three subjects, a high information transfer rate of 75.4 bits/min was achieved.
