This study focused on the predictability of signboard noticeability by using analogy with illuminance calculation. Light source that modeled eyesight attribution was incorporated under 3D lighting simulation of the experimental condition. Based on previous study on visibility and legibility, area, luminance contrast, font factor and number of letters were used to derive the induced sight amount. Using logistic analysis, threshold value to notice was calculated, which equaled to condition of visual acuity of 0.7. Experiment 2 was done to verify the threshold value.As a result, relationship between numbers of noticed people and points that exceeded threshold value was seen.
We studied the imprevement of temporary system in conformity with practical use , and added the grade 3 which is existed in the middle of grade l and grade 2. We (
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
