EEG measurements towards brain life-log system in outdoor environment

Abstract

In this paper, we studied electroencephalogram during ambulatory conditions in outdoor environment. Five healthy subjects participated in this experiment. The task of the self-paced walking subjects was to count the number of appearances of the target auditory stimulus using oddball paradigm. We observed P300 evoked potentials in ambulatory conditions in outdoor environment as well as sitting conditions in indoor environment. Our results are encouraging and make new direction to promising novel applications of ambulatory BCIs. © 2011 Springer-Verlag.
