ABSTRACT
Metaphors could be used to help older adults build mental models of Information and Communication Technology (ICT) applications and services and thereby reduce the number of interaction problems, but currently, metaphors generally are not tailored to these older adults, and their construction remains vague. Inspired by concrete icons, this study proposes concrete metaphors to help novice older adults understand ICT applications and services and retains their knowledge over time. A new communication application based on concrete metaphors was designed, developed, and comparatively tested against another application based on abstract metaphors over a period of 9 days. The results indicated that the application with concrete metaphors contributed to fewer perception and cognition errors, higher usage intention, higher satisfaction, and higher preference compared to the application with abstract metaphors. In addition, the advantage of concrete metaphors was lasting, unlike concrete icons. These findings indicated that concrete metaphors could be an icebreaker or stepping stone to draw novice older adults into the information society. To further increase the impact of concrete metaphors, representing real-world operations is an essential challenge.
