Abstract:
In recent times, Steady State Visually Evoked Potentials
(SSVEP) based BCI have gained popularity over different
types of brain signals as they prove to demonstrate interesting
results. It is important to understand the behavior of brain signals
with the change of frequency and distance to the stimuli used to
evoke them. In this paper, we have looked at the behavior of the
SSVEP signals over 4 varying stimuli frequencies and 4 varying
distances between the subject and the stimulus. It was found that
the strongest SSVEP were elicited in the lower frequency range
around 8Hz and a distance up to 100 cm can have a significant
effect on the elicited SSVEP signals.
