Abstract
In our lives, we look at a specific object mainly in central vision and peripheral vision is an auxiliary. However, peripheral vision has some outstanding features such as sensitiveness to light-dark change and moving target. In recent years, these features are focused on some fields such as sports vision and visual inspection, and many applications to these fields have been researched. In this study, we focused attention on information presentation systems designed on the basis that these should be looked in central vision. In consideration of these peripheral vision characteristics, it is more effective under an emergent situation which needs quick thinking than presenting of an information calling for attention in central vision to present it in peripheral vision. Hence, we verified an appropriate vision angle to present visual signal such as the information calling for attention by an experiment measuring reaction time to blinking LEDs setting around a test subject as simple visual stimuli. This measuring experiment proved that the reaction time to visual stimuli in peripheral vision was smaller than the reaction time to visual stimuli in central vision.
