Summary:
It is known that the attention time towards a target stimulus is delayed, when a person with high stress levels uses an SSVEP-based BCI. However, conventional research uses a flash stimulus for the visual stimulus. This means that practical knowledge is not sufficiently discussed since many of BCIs use a pattern reversal stimulus to evoke EEG responses. In addition, the level of stress is not quantified. In this paper, we measure SSVEP induction and the LF/HF ratio to analyze the relationship between SSVEP and stress level.
