A Comparative Study of Icon Style Based on Cognitive Behavior

With the rapid development of mobile applications and the popularity of intelligent living environments, people's demand for the experience of using mobile devices is constantly increasing. As an important element in the interaction between users and mobile devices, the design form of interactive interface icons is also evolving. This study starts with the development trend of icon style in the interactive interface, adopts the research method of cognitive behavior, designs behavior experiments with the help of E-prime, a computerized behavior research platform, and compares the influence of flat icons and neumorphic icons on users' search performance and use experience in combination with subjective evaluation, to provide a quantitative decision-making basis for icon design decisions. According to the statistical results of experimental test data, the flat icon is slightly better than the neumorphic icon in icon search performance, the neumorphic icon has advantages in user preference and eye comfort, and the flat icon has certain advantages in clarity. The evaluation data of the flat icon and neumorphic icon are weighted by the weight of the evaluation index, and finally, it is concluded that the comprehensive performance of the flat icon is better than that of the neumorphic icon, which provides a reference for the design of interactive interface icon.
