Research of Information Presenting Method Based on Characteristics of Peripheral Vision

从应用于信息呈现系统的角度出发，通过对LED闪烁的反应时间和主观评价实验，验证了合适的视角和闪烁模式可以呈现出引起注意的信息等视觉信号。反应时测量实验证明，周边视觉对视觉刺激的反应时小于中心视觉和周边视觉对视觉刺激的反应时，尤其是30 ~ 50度视角比中心视觉更适合呈现引起注意的信息。 接下来，我们使用“清晰度”的心理测量来识别多种闪烁模式的可见性。实验结束后，我们从图形中选取了几种清晰度较高的闪烁图形，并得到了它们的反应时。结果表明，不同的心理测量结果与反应时相关。

From a perspective of application to information presentation system, we verified an appropriate vision angle and flickering pattern to present visual signal such as the information calling for attention by an experiment measuring reaction time and subjective assessment to blinking LEDs. Measuring experiment of reaction time proved that the reaction time to visual stimuli in peripheral vision was smaller than the reaction time to visual stimuli in central vision and peripheral vision, especially from 30 to 50 degrees vision angle is more suitable than central vision for presenting information calling for attention. Next, we identify the visibility of many kinds of flickering patterns using the mental measure of "distinctness". After the experiment, we select a few kinds of flickering patterns with higher distinctness out of patterns, and obtain the reaction time to their patterns. The results indicated that the mental measure of distinctness is correlated to reaction time.
