Estimation of the Tracking States of Multiple Moving Targets by Steady State Visual Evoked Potential

Abstract

In daily life, we can attend to multiple moving objects. For example, the drivers always pay attention to pedestrians, cars and so on while driving a car. Attention to multiple moving targets is an essential ability of visual system. Extracting information to which the driver pays attention may allow us to prevent the accidents caused by lack of attention. To investigate attentional status to multiple moving objects, steady state visual evoked potential (SSVEP) elicited by these stimuli when participants were instructed to track two moving targets among three. The results showed that SSVEP amplitudes differed depending on attentional states, meaning that it is possible to extract attentional states to multiple moving targets using SSVEPs. Future studies include estimation of the level of the subject's concentration to multiple moving targets using SSVEPs.
