Abstract
Following my previous studies about "the effect of animation character display method to user's reading", I now evaluated the people stimulation with an EEG (electroencephalogram). According to the results of the experience, among five kinds of motion of a word onto a screen, it appeared that when each unit of character of a word are displayed successively one by one onto the screen the mental activity attention is high. And when a full word is displayed many times in a short time the mental activity low.
