Abstract

With the advancements in hardware and information technology, the use of dynamic icons in travel app interfaces to convey information has become increasingly common. The goal is to provide users with a novel experience that was not available in the static interfaces of the past. However, it remains unclear whether the availability and utilization of dynamic icons actually enhance the usability of apps and if it is done with genuine consideration for users' benefit. This study aims to investigate how users perceive and use dynamic icons in the context of human-computer interaction, using a travel app as the research object. We propose a user-centered subjective and objective hybrid evaluation methodology to examine the perceived usability of dynamic icons, taking into account different evaluation characteristics at various usability levels. Our results indicate no significant statistical difference between the perceived usability of dynamic icons and static icons. We employed two indicators, perceived ease and subjective priority, to evaluate the perceived usability of dynamic icons. The findings show that the perceived ease of dynamic icons is higher than that of static icons, with an increase of 3.72% (I) and 3.09% (II) in respective studies, but with a reduction of 13.19% compared to static icons in study III. We conclude that although the perceived usability of dynamic icons may not be significantly different from static icons, they exhibit higher objective usability in users' decision-making behavior.
