Description

<p>The caution making is used in various daily situations as a preventive measure of tumble accident which is one of the labor accidents. The purpose of this study is to propose a display that incorporates the Fraser-Wilcox illusion and has a higher attention effect. Fraser-Wilcox illusion is a type of visual illusion in which a part of a still image appears to be moving. We compare the attention effects of shapes that induce the Fraser-Wilcox illusion and those that do not. As an evaluation method of attention recall effect, the pre-cueing task which was an experimental technique to measure the characteristics of visual attention was used. The correlation between the amount of visual illusion and the target reaction time was examined. As a result, a strong negative correlation was observed. The larger the amount of visual illusion, the faster the detection of the target. These results suggest that the Fraser-Wilcox illusion has an alerting effect on visual illusion.</p>
