Abstract
We investigated whether attention on both changes of geometric figures drifting in the screen and sentences scrolling along the screen of the screen edges depend on the screen size, using displays of which sizes were 15 and 4 inches. There were not significant difference in accuracy rate of sentences and detection of figure change between 15 and 4 inches display. Most of participants answered that conspicuous display was 15 inches in subjective assessment. However, some participants exhibited better record for 4 inches than 15 inches on chacges of geometric graphics.
