The relationship model construction of dynamic color and visual attention based on mobile card layout

With the rapid development of mobile application industry, the interaction between human and mobile application interface has become an indispensable part of daily life. Designers also strive to guide users' visual attention reasonably on the limited screen. This paper analyzes the design elements of dynamic color in the mobile terminal card layout, establishes the relationship model between dynamic color and visual attention in mobile end card layout, and explores the relationship between dynamic color and visual attention of users. Based on the analytic hierarchy process (AHP), this paper constructs an index system that affects users' visual attention. By designing the control group experiment, users can evaluate the importance of the index layer factors in pairs, and finally get the weight value of the influence of color, purity, lightness and speed of the design factors of dynamic color on the visual note. The model can provide a theoretical basis for the design of dynamic color of mobile card layout and a method for designers to calculate the visual attention degree of interface elements to users.
