When making Event Related Potential measurements, the intrusion of several artifacts, like eye movements, muscular activities and environmental noise, is an important problem. We assessed an independent component analysis method for dynamically eliminating such artifacts. Using this method we could extract the P3 component of the Eye-Fixation Related Potential (EFRP). Here we present the results of this method and also the effects of the workload caused by information processing on the P3 latency time, and also refer to the possibility to assess the cognitive load using P3 latency in EFRP.
