Abstract
A number of studies have been conducted to evaluate the ease of seeing signs in public spaces. Most of these studies have focused on aspects of visibility or attention value, such as figure-ground segregation or difference in brightness between two areas. This study will focus on readability and understandability of the public sign, both of which are important aspects of signs. To recognize objects and scenes, we use previous knowledge as well as perceptual information. Studies on color memory indicate that knowledge of typical colors of objects can help with object identification. Focusing on the visual characteristics and cognitive functions of human beings, we consider the elements of a new ” visibility” in this paper.
