The influence of flickering patterns on the quality of brain signals for Brain-Computer Interface

Abstract

This paper investigates brain’s response to visual stimulation using ten different flickering patterns, which were designed and tested at 10 Hz oscillation in multiple trials using white light only. The tests were carried out in a normal office environment. The resulting brainwaves were compared by looking at the fundamental 10 Hz peak levels, noise floor and harmonic artifacts. The tests proved that there is a fundamental relationship between flicker patterns and the brain signals they elicit.
