The investigation of the human characteristic on visual and auditory reaction time is very important for making high-reality virtual environment and safe uses of multimedia machines. Up to now, human visual and auditory mechanisms have been investigated as two separate systems. In this study, we pay attention to human characteristics of the visual and auditory calculation processing, and the reaction time and electroencepha-logram (EEG) are measured. Based on the measurement results and the results in our previous functional magnetic resonance imaging (fMRI) study, the authors discuss the difference between the visual and the auditory information processing.
