Functional illiterates make up a significant portion of the population and need accessible interfaces. Icons, among other interface elements, are a design consideration that is often used to improve accessibility. However, neurophysiological evidence on their effectiveness in functional illiterates remains scant. In a controlled experiment based on online banking stimuli, this study used EEG and behavioral measures to objectively evaluate the efficaciousness of icons compared to words in literate and functional illiterate subjects. Results show that icons alone might not be sufficient to increase accessibility because their abstract nature can hinder their interpretation.

摘要

Functional illiterates make up a significant portion of the population and need accessible interfaces. Icons, among other interface elements, are a design consideration that is often used to improve accessibility. However, neurophysiological evidence on their effectiveness in functional illiterates remains scant. In a controlled experiment based on online banking stimuli, this study used EEG and behavioral measures to objectively evaluate the efficaciousness of icons compared to words in literate and functional illiterate subjects. Results show that icons alone might not be sufficient to increase accessibility because their abstract nature can hinder their interpretation.
