‘Graphic elements for easy-to-understand Pictograms – Comparison of General Early Adolescent and Adult Intellectual Disability Groups’ by Mao Kudo
Summary
This study investigated 20 pairs of pictograms to clarify the graphic elements of easy-to-understand pictograms for early adolescents and adults with intellectual disabilities, an attribute not covered by ISO 9186-1. The results showed that the following graphic elements were easily understood by both groups: (1) Person symbolizing the location, actions or actions to be performed at a place, (2) Symbolic element representing a place, (3) Direction of an item by real-life usage, (4) Motion line, (5) Arrow: the axis length that is twice the width of the arrow feather. However, there were differences between the adult intellectual disability group and the general early adolescent group in items where JIS was significantly easier to understand. As factors that caused the difference between the two groups, we considered differences in reading the meanings indicated by metaphors, visual perception of symmetrical forms, and retrieving ideograms from pictographs. Pictograms are the next step in standardization that responds to the diversity of each user.
