Abstract
According to IEEE PAR1789, flicker and the stroboscopic effect may induce biological response and health risks. This study designed an LED light generating different frequency strobe stimuli and recorded the electrodermal activity (EDA) signal under different frequency strobe stimuli. The EDA signal processing algorithms to study and analyze the influence of flicker on EDA signal are implemented, including the normalization of EDA signal, frequency filtering, and skin conductance response (SCR) positioning algorithm. To the best of our knowledge, this is the first to study the influence of flicker and the stroboscopic effect by EDA signal. The results show that flicker and the stroboscopic effect can influence the EDA signal, which indicates that flicker may influence the sympathetic nervous system. Moreover, this may also be the reason why flicker can induce human health risks.
