Examination of environmental factors that affect the “oversight” of displayed objects in public spaces -Analysis of experimental results for young adults-

Abstract

This study aims to clarify the environmental factors that can cause “oversight” of displayed objects that help people who move in public spaces. We installed a display in a shaded space and conducted a search experiment and an impression evaluation experiment by presenting a still image of public space. As a result, we clarified the factors of “oversight” as follows: 1) The visual features of the target, such as position and size, affect “oversight” basically, and especially the “emergency exit” is affected by the color and design associativity that examiner has. 2) The following three things tend to make “oversight” less likely to occur: reduced ceiling brightness for small targets near the ceiling; reduced vertical surface brightness for small and low-brightness targets; and decrease the number of displayed objects for targets that mainly contain text and number information and include multiple pieces of information. 3) Reduced vertical surface brightness makes the impression of space neat, spacious, and dark. Decrease the number of displayed objects reduces the psychological burden on the subject because it makes the space neat and spacious and enhances the overall positive impression.
