The work aims to explore an interactive default interface expression that can most effectively reduce the negative emotions of users and improve the user experience. In this thesis, anthropomorphism and metaphor, the most commonly used design methods for default pages, were selected as the research objects to explore the rationality of different default page design through the Positive and Negative Affect Schedule (PANAS) as well as the eye tracking technology. The experimental results revealed that anthropomorphism had a significant impact on user emotions. Expressional anthropomorphism significantly decreased the emotional valence of users, while postural anthropomorphism increased the emotional valence. Metaphor had no significant effect on users' emotions. Compared with real metaphor, unreal metaphor increased the subjective preference of subjects. Young people prefer the default page design with postural anthropomorphism because of their perception uncertainty Unreal metaphor is more favored by young users because of its humor. The unreal metaphor-postural anthropomorphism combination has the advantages of low cognitive processing cost and fun, so it becomes the best collocation combination. Postural anthropomorphism and unreal metaphor are effective means to improve default page user experience.
